The objective of the present study was to determine the best phosphite source and concentration to control anthracnose and its effects on the physical and chemical characteristics of ‘Prata-anã’ banana. Bouquets of banana fruits were immersed in solutions containing different formulations of copper phosphite FCu1 (4% Cu + 20% P2O5), FCu2 (4% Cu + 22% P2O5) at concentrations of 0.5; 1.0, 1.5- and 2.0-mL L-1 and potassium phosphite FK (42% P2O5 + 27.7% K2O) at concentrations of 0.5; 1.0, 1.5 and 2.0 mg L-1. Controls consisted of the application of pure water and Imazalil application (0.5 mL. L-1). Subsequently, anthracnose incidence and severity were evaluated every three days. The physical and chemical characteristics of fruits were evaluated at the end of the anthracnose intensity evaluation. The experimental design used was completely randomized. The results showed that the different phosphite sources FCu1, FCu2 and FK at the concentrations tested were not effective in controlling anthracnose. The physical and chemical characteristics of fruits were influenced by the different phosphite sources and concentrations applied. Fresh fruit mass loss is proportional to the applied phosphite concentration. Resumo Objetivou-se com o presente estudo determinar a melhor fonte e concentração de fosfito no controle da antracnose e seus efeitos nas características físicas e químicas em banana ‘Prata-anã’. Buquês de frutos de banana foram imersos em soluções contendo as diferentes formulações de fosfito de cobre FCu1 (4% de Cu + 20% de P2O5), FCu2 (4% de Cu + 22% de P2O5), nas concentrações de 0,5; 1,0; 1,5 e 2,0 mL L-1, e fosfito de potássio FK (42 % de P2O5 + 27,7% de K2O) nas concentrações de 0,5; 1,0; 1,5 e 2,0 mg L-1. As testemunhas consistiram na aplicação de água pura e aplicação do Imazalil (0,5 mL.L-1). Posteriormente, foram avaliadas a incidência e a severidade da antracnose a cada três dias. As características físicas e químicas dos frutos foram realizadas no término da avaliação da intensidade de antracnose. O delineamento experimental utilizado foi o inteiramente casualizado. Os resultados demonstraram que as diferentes fontes de fosfito FCu1, FCu2 e FK, nas concentrações testadas, não apresentaram eficácia no controle da antracnose. As características físicas e químicas dos frutos foram influenciadas pelas diferentes fontes e concentrações de fosfito aplicadas. A perda de massa fresca dos frutos é proporcional à concentração de fosfito aplicada.

Mango (Mangifera indica L.) has great socioeconomic importance to Brazil, but its production is affected by anthracnose. Chitosan films have shown potential in controlling this disease. In this study, the effect of the association of chitosan with phenolic compounds and extracts on the Colletotrichum tropicaledevelopment was evaluated. Phenolic compounds and extracts from mango peel were incorporated into 2.0% chitosan solutions and tested in vitro. In the in vivo experiment, after pathogen inoculation and application of treatments, fruits were evaluated for anthracnose incidence and severity. Controls consisted of the application of water or pure culture medium and fungicide imazalil. The experimental design was completely randomized and data were submitted to analysis of variance. In the in vitro test and in the assessment of disease intensity, means were compared using the Scott-Knott and Tukey tests (p

Aims: The study objective was to determine the harvest point of red pitaya produced in the north of Minas Gerais, Brazil, according to physical and chemical changes during refrigerated storage. Study Design: The experiment was conducted through a completely randomized design in a 3 x 5 factorial scheme composed of three treatments (ripening stages) and five post-harvest assessment days (0, 5, 10, 15 and 20), with four repeats of four fruits per experimental unit. Study Place and Duration: The experiment was conducted in a cold chamber at the State University of Montes Claros, Brazil, between July and August 2018. Methodology: The following quality parameters were assessed: fruit fresh mass, length and diameter at harvest point, color, firmness, soluble solid content, titratable acidity, total sugars, reducing and non-reducing, pH and amide, during storage. Results: There was no significant difference for fresh mass, length and diameter as a function of ripening stages. Ripening stages 2 and 3 presented higher soluble solid content means. Conclusion: Considering the conditions of northern Minas Gerais, harvest should happen at stages 2 or 3, when fruits have a brighter red hue, that is, are more attractive and of easier identification by producers. In addition, pitayas at these stages have higher soluble solid contents and reduced pulp acidity during storage in relation to fruits harvested at S1.

Objective: The objective of this study was to assess the effect of hydrothermal treatment applied to banana ‘Prata-Anã’ before refrigerated storage. Study Design: The employed experimental design was the completely randomized type (CRD) and composed of 4 repeats with 4 fruits, in a 5 x 4 +1 factorial scheme, with five storage days (days 1, 2, 3, 4 and 5) at 25°C after removal from the refrigerated chamber, four immersion temperatures and one control (fruits without hydrothermal treatment). Study Location and Duration: The experiment was conducted in the Post-Harvest Physiology Laboratory of the State University of Montes Claros between March and June 2017. Methodology: The bananas were harvested and separated into 4-fruit bouquets, which were immersed in water at 50, 52, 54 and 56°C for 2 minutes; fruits without hydrothermal treatment were used as control. Each bouquet was placed in polyolefin membrane packs that were then contained in boxes and stored in chambers at 10oC and RH of 80% for 25 days. After the 25 days, the fruits were taken out of the chamber and stored at 25oC. During the 25oC storage, physical and chemical analyses were performed. Results: On the day of removal from the refrigerated chamber, all bananas, regardless of treatment, presented a yellowish color. The temperature of 56oC resulted in greater fresh mass loss and higher solute extravasation values. Lower chilling index values and higher vitamin C values were found as the immersion temperature increased. Conclusion: The full ripening process of banana ‘Prata-Anã’ occurred after removal from the refrigerated chamber in all hydrothermal treatments and with lower chilling index values.

Aims: To evaluate the in vitro effect of mango peel extracts using different types of solvent and concentrations on the Colletotrichum gloeosporioides development. Study Design: Activities were aimed at evaluating the in vitro antifungal potential of mango peel extracts. Study Location and duration: The study was carried out at the Laboratory of Post-Harvest Pathology of Fruits and Vegetables - State University of Montes Claros and Laboratory of Natural Products, Department of Chemistry - Federal University of Lavras during October and December 2018. Methodology: ‘Palmer’ mango peel (Mangifera indica) was submitted to drying in oven and grinding. Subsequently, extracts were obtained in Soxhlet system, using methanol, ethyl acetate and hexane as solvents. The three extracts were tested in vitro at concentrations of 0.0; 0.25; 0.5; 1.0 and 2.0 mg/mL by adding them in culture medium against C. gloeosporioides, which was isolated from mango fruits with anthracnose symptoms. The effect of extracts and their respective concentrations on the mycelial growth rate and conidia production and germination was evaluated. The design was completely randomized in a 3 x 5 factorial arrangement with 5 replicates. Results: Increased extract concentrations caused reduction in the mycelial growth rate of the pathogen (R2 = 0.96). Both factors under study acted simultaneously in conidia production (P < 0.05), and the hexane extract presented better results for this analyzed variable. There was total germination inhibition (P < 0.05) when 1 mg/mL ethyl acetate extract and 2 mg/mL methanol and hexane extracts were used. Conclusion: Methanol, hexane and ethyl acetate mango peel extracts had inhibitory effect on the in vitro C. gloeosporioides development.

Banana as a climacteric fruit has a relatively short shelf-life period and thus, technologies that decrease the metabolism and the triggering of the maturation process are extremely necessary on its postharvest conservation. However, the consequences of these technologies on quality attributes are unknown. Therefore, we evaluate the effects of 1-Methylcyclopropene associated with low density polyethylene bags on physical and chemical attributes in the postharvest of banana fruits. Bananas were treated with different concentration of 1-Methylcyclopropene as 0, 50, 100, 150 and 200 ηL.L-1 under refrigeration and harvest in five different times after treatment. Further, fruits treated with 50 ŋL.L-¹ showed a more advanced stage of ripening after the 25 days of storage. Altogether, our results suggest 1-MCP is an effective treatment to control sugar and starch metabolism in banana and its efficiency is directly dependent of storage temperature. Additionally we identify interestingly correlation with skin color changes with sugars and starch content, which can indicate its potentiality of the fitted equations for prediction of central metabolism of bananas non-destructively using ‘hue angle and chrome’ value.

Aims: The objective of this study was to evaluate the effect of the modified atmosphere under refrigeration for 28 days in the Atemoya Gefner. Study Design: Experiment 1 and 2 was installed in a completely randomized design, in a factorial 1x4 and 2x8, respectively. Place and Duration of Study: The experiment was conducted in a cold chamber at the State University of Montes Claros, Brazil, between July and August 2018. Methodology: In the first, the percentage of fruits that presented cold injury (CI) in unpackaged fruits and stored at 15°C for six days was visually evaluated. In the second experiment two pack were used and stored at 15°C and evaluated the physical and chemical characteristics. Results: In the first experiment, from the 2nd day 100% of the fruits showed CI that progressed to stage 3 on the 6th day of storage. This result justifies the need to store the atemoya under modified atmosphere under 15°C for 28 days. It was found at the end of 28 days, experiment two, that the packages 1 and 2 showed quality fruits, with characteristics of ripe fruits, with 22 °Brix average values, reduced titrable acidity, light green color peel and good lightness. The pack1 showed better weight maintenance, with 1.54% of fresh weight loss against 2.36% for pack2. Conclusion: There was a higher solubilization of total sugars and non-reducing sugars in pack1, being this the most indicated for atemoya fruits grown in northern Minas Gerais.

The aim of this study was to evaluate the anthracnose intensity in ‘Prata-Anã’ banana with the application of three phosphite formulations in two application intervals in the developing banana bunches and to evaluate the physical and chemical characteristics of fruits. In the field, in addition to producer management, three phosphite formulations were evaluated: FCu1 (4% Cu + 20% P2O5), FCu2 (4% Cu + 22% P2O5) and FK (42% P2O5 + 27.7% K2O) sprayed on banana bunches at different application frequencies: four and eight times. The experiment was carried out in a randomized blocks design following a 5 x 2 factorial scheme, with 3 phosphite formulations, pure water and no application and two application intervals. Pure water and no application were used as control. Fruits were harvested, stored in refrigeration chamber (25 ± 1 ° C and 80 ± 5% RH) and evaluated for anthracnose incidence and severity, as well as physical and chemical characteristics. The application of copper phosphite can control anthracnose incidence by 38% and severity by 49.5%. The frequency of phosphite application does not affect anthracnose intensity. FCu1 phosphite application in ‘Prata-Anã’ banana bunches, as well as eight phosphite applications increases fresh mass loss. Phosphite application frequency affected the chemical characteristics of banana fruits. Resumo O objetivo do trabalho foi avaliar a intensidade de antracnose em banana ‘Prata-Anã’ com aplicação de três formulações de fosfito, em dois intervalos de aplicação nos cachos da bananeira em desenvolvimento, e avaliar as características físicas e químicas dos frutos. No campo, em adição ao manejo do produtor, foram avaliadas três formulações de fosfito: FCu1 (4% de Cu + 20% de P2O5), FCu2 (4% de Cu + 22% de P2O5) e FK (42 % de P2O5 + 27,7% de K2O) pulverizados nos cachos da bananeira, em diferentes frequências de aplicação: quatro e oito vezes. O experimento foi conduzido em blocos casualizados, seguindo esquema fatorial 5 x 2, sendo 3 formulações de fosfito, água pura e sem aplicação e dois intervalos de aplicação. Foram adotadas como testemunha água pura e ausência de aplicação. Os frutos foram colhidos, armazenados em câmara de refrigeração (25 ±1°C e 80 ±5% UR) e avaliados quanto à incidência e à severidade da antracnose bem como as características físicas e químicas. A aplicação de fosfito de cobre pode controlar a incidência da antracnose em até 38%, e a severidade, em 49,5 %. As frequências de aplicação dos fosfitos não interferem na intensidade da antracnose. A aplicação de fosfito FCu1 nos cachos de banana ‘Prata-Anã’, assim como realizar oito aplicações de fosfitos, aumenta a perda de massa fresca. A frequência de aplicação dos fosfitos interferiu nas características químicas dos frutos de banana.

FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior The balanced supply of nitrogen to fruit trees leads to higher fruit quality and reduced incidence of diseases. The aim of this study was to evaluate anthracnose intensity and the physical and chemical characteristics of ‘Prata Anã’ banana under different nitrogen doses. Regarding anthracnose intensity, N doses of 150, 200, 250, 400 and 600 kg ha-1 were used. The Area Under the Incidence Progress (AUIPC) and Severity Curves (AUSPC) were evaluated. The physical and chemical characteristics were: fruit and pulp mass; soluble solids; starch; total, reducing and non-reducing sugars; coloration and nutrient concentration in peel, evaluated every three days for 15 days. Plants fertilized with N doses of 200, 250 and 400 kg.ha-1 had lower AUIPC values and the application of 250 kg.ha-1 reduced AUSPC in fruits inoculated with C. musae. N, P and K increased in banana peel, fruit and pulp mass, soluble solids, starch, total sugars, reducing sugars, with increasing N doses. There was no difference in the contents of micronutrients in fruit peel. N dose of 600 kg.ha-1 reduced the shelf life of fruits and provided higher sugar content and higher disease severity. O fornecimento equilibrado de nitrogênio para as fruteiras propicia maior qualidade dos frutos e redução de doenças. O objetivo foi avaliar a intensidade de antracnose e as características físicas e químicas em banana- ‘Prata-anã’ sob diferentes doses de nitrogênio. Na intensidade de antracnose, foram utilizados 150; 200; 250; 400 e 600 kg.ha-1 de N. Avaliaram-se a Área Abaixo da Curva de Progresso da Incidência (AACPI) e a Severidade (AACPS). As características físicas e químicas foram: massa do fruto e polpa; sólidos solúveis; amido; açúcares totais, redutores e não redutores; coloração e concentração de nutrientes na casca, avaliadas a cada três dias, por 15 dias. Plantas adubadas com 200; 250 e 400 kg.ha-1 de N apresentaram menores valores de AACPI, e a aplicação de 250 kg.ha-1 reduziu a AACPS em frutos inoculados com C. musae. Obteve-se aumento de N, P e K na casca da banana, na massa do fruto e da polpa, sólidos solúveis, amido, açúcares totais, açúcares redutores, com o aumento das doses de N. Não houve diferença nos teores de micronutrientes na casca dos frutos. A dose de 600 kg.ha-1 reduziu a vida de prateleira dos frutos e proporcionou maior teor de açúcar e maior severidade de doença.

O objetivo do trabalho foi determinar a época de ensacamento da banana ‘Prata-Anã’ visando a reduzir a doença antracnose. Os tratamentos consistiram na proteção dos cachos de banana com sacos de TNT na emissão de 30; 60; 90 e 120 dias após a emissão e de cachos não ensacados. Os frutos foram colhidos, armazenados em câmara de refrigeração (25 ±1°C e 80 ±5% UR) e avaliados quanto à incidência e a severidade da antracnose. O delineamento foi o inteiramente casualizado, com seis tratamentos, repetidos em dois anos. Os dados foram submetidos à análise de variância e teste de Tukey (p

The introduction of rhizobacteria to the soil can be done via treatment of propagating materials. The aim of this work was to evaluate in greenhouse the influence of immersion periods of micropropagated ‘Prata-Anã’ banana seedling roots in suspension of different rhizobacterial isolates on the growth of seedlings and control of Meloidogyne javanica. The experiment was set up in greenhouse in a randomized block design in a 10 x 2 factorial scheme (rhizobacteria isolates) x (immersion periods: 60 and 120 minutes) with 10 replicates. The additional treatment (control) was composed of seedlings without any treatment infected with M. javanica. Treated seedlings were planted in pots containing soil: previously autoclaved sand. After twenty-four hours, suspension containing 3,000 M. javanica eggs was added to the soil. At 60 days, number of galls, egg mass and eggs per root system, number of second-stage juveniles (J2) per 100 cm3 of soil were evaluated and the reproduction factor was calculated. Shoot dry matter mass was also evaluated. Of the four rhizobacteria that reduced the reproductive capacity of the nematode, three were more efficient when seedlings were treated for 120 minutes. The treatment period of banana seedlings did not affect the shoot dry matter yield and all rhizobacteria increased the dry matter weight of seedlings infected with Meloidogyne javanica. It could be concluded that rhizobacteria have different treatment time requirements for seedlings to control the nematode, but do not interfere with the development of seedlings. Resumo A introdução de rizobactérias ao solo pode ser feita via tratamento de materiais propagativos. O objetivo deste trabalho foi avaliar, em casa de vegetação, a influência de períodos de imersão de raízes de mudas de bananeira ‘Prata-Anã’ micropropagadas, em suspensão de diferentes isolados de rizobactérias no crescimento de mudas e no controle de Meloidogyne javanica. O experimento foi montado em casa de vegetação, em delineamento em blocos ao acaso, em esquema fatorial 10 (isolados de rizobactérias) x 2 (períodos de imersão: 60 e 120 minutos), com 10 repetições. O tratamento adicional (testemunha) foi composto por mudas sem nenhum tratamento, infectadas com M. javanica. As mudas tratadas foram plantadas em vasos contendo solo: areia previamente autoclavados. Após vinte e quatro horas, suspensão contendo 3.000 ovos de M. javanica foi adicionada ao solo. Aos 60 dias, avaliaram-se: número de galhas, de massas de ovos e de ovos por sistema radicular, número de juvenis de segundo estádio (J2) por 100 cm³ de solo e calculou-se o fator de reprodução. Avaliou-se também a massa de matéria seca da parte aérea. Das quatro rizobactérias que reduziram a capacidade reprodutiva do nematoide, três foram mais eficientes quando as mudas foram tratadas por 120 minutos. O período de tratamento das mudas de bananeira não afetou a produção de matéria seca da parte aérea e todas rizobactérias aumentaram o peso da matéria seca de mudas infectadas com Meloidogyne javanica. Conclui-se que as rizobactérias têm requerimentos diferentes de tempo de tratamento de mudas para controlarem o nematoide, mas não interferem no desenvolvimento das mudas.

Os nematoides do genero Meloidogyne sao responsaveis por perdas elevadas no pepineiro em campo e cultivo protegido. Devido a ausencia de cultivares resistentes, o uso de silicato de calcio pode ser uma alternativa para o controle dos nematoides. Objetivou-se avaliar a eficiencia de diferentes doses de silicato de calcio em solo de textura arenosa e argilosa no controle de M. javanica em pepineiro. Para a avaliacao do efeito das doses de silicato de calcio no controle de M. javanica em pepino de conserva em solo arenoso foram avaliadas quatro doses de silicato de calcio, 0 (testemunha), 1: 0,5g.kg -1 , 2: 0,8g.kg -1 , 3:1,1g.kg -1 de solo. Para a avaliacao em solo argiloso utilizou-se as seguintes doses: 0 (testemunha), 0,2 g.kg -1 , 0,5 g. kg -1 , 0,8 g.kg -1 . O delineamento estatistico foi em blocos ao acaso com cinco repeticoes e cada repeticao composta por dois vasos, para os dois ensaios. Com relacao ao numero de juvenis de segundo estadio (J2) por 100 cm3 de solo no ensaio realizado em solo arenoso constatou-se reducao de 74,29% na dose de 1,1g/kg de solo quando comparado a testemunha. No ensaio em solo argiloso foi observado efeito significativo das doses de silicato de calcio na reducao do numero de ovos. Nao houve efeito sobre o desenvolvimento da planta.

Anthracnose stands out among rot diseases that can occur in the post-harvest phase of banana. The aim of this study was to evaluate the thermotherapy in the control of anthracnose in ‘Prata Anã’ banana produced in northern state of Minas Gerais. Bananas ‘Prata Anã’ variety were divided into groups of three fruits and inoculated with Colletotrichum musae. Groups were submitted to thermotherapy using five temperatures (40°C, 44°C, 48°C, 52°C and 56°C) and four immersion times (4, 8, 12 and 16 minutes) and control. Treatments were repeated five times in a completely randomized design. Area under the incidence progress curve (AUIPC) and area under the severity progress curve (AUSPC) were calculated. To evaluate the thermotherapy efficiency compared to chemical control, fruits were submitted to the following treatments: thermotherapy with and without fungicide application and fruits treated with fungicide only, the control fruits without thermotherapy and without fungicide application. After fifteen days of storage, fruits were evaluated for anthracnose severity. The results of experiments were submitted to analysis of variance and regression and means were compared by the Scott-Knott test (p

ABSTRACTThe pink pitaya of red pulp is a cactacea with potential for economic exploitation, due to its nutritional components and high commercial value, however there is little research about its post-harvest characteristics. The aim of this study was to characterize physical, chemical and nutritionally pink pitaya of red pulp. Fruits harvested fully ripe were sanitized, selected and divided into groups of four fruits per repetition, constituting a total of 30 samples. Then the samples were subjected to the following evaluations: length, diameter, peel thickness, freshmatter, peel and pulp mass, moisture content, peel firmness, soluble solids, pH, titratable acidity, sugars and crude fiber, chromaticity, hue angle and brightness of the peel and pulp and nutrient content. For the obtained data, it was determined mean, minimum and maximum values, standard deviation and coefficient of variation. The fruit showed high water content, content of fiber and nutrients nitrogen, potassium, calcium, iron, manganese and zinc. As for soluble solids content it was observed average of 13.14 ° Brix and titratable acidity 0.29 mg of Malic acid in 100-1 ml of juice. For sugars were found values of 5.56, 8.79 and 3.07% respectively for the reducing sugars, total and non-reducing ones. As for color, the fruits showed higher values for brightness and chromaticity of the peel and the Hue angle of the pulp. The pink pitaya of red pulp (Hylocereus polyrhizus) has interesting physical, chemical and nutritional characteristics to be consumed in nature.

The genetic distances ranged from 0.06 to 0.56 and the average distance of 0.21. A dendrogram constructed based on the UPGMA clustering method revealed 8 and no correlation between molecular grouping and geographical origin was observed.

Durante a extração do mesocarpo interno do pequi que corresponde à parte comestível e possui valor comercial, são descartados no ambiente o exocarpo e o mesocarpo externo. Objetivou-se neste trabalho investigar o uso do extrato aquoso e do pó moído dos resíduos de pequi no controle do nematóide das galhas (Meloidogyne javanica). Do exocarpo e do mesocarpo externo foram obtidos extrato aquoso e o pó moído. Cinco doses do extrato aquoso (0,0; 2,5; 5; 10 ou 20%) foram avaliadas quanto ao efeito na eclosão e mortalidade de juvenis de segundo estádio (J2) do nematóide das galhas in vitro. Os ensaios foram montados em delineamento inteiramente casualizado com 10 repetições por tratamento. O teste de eclosão foi feito em câmaras de eclosão às quais foram adicionados 800 ovos do nematoide e 10 mL das diferentes doses do extrato. Durante 14 dias contou-se o número de J2 eclodidos com auxílio do microscópio ótico. O ensaio de mortalidade de J2 do nematóide das galhas foi avaliado colocando-se 100 μL de cada dose do extrato em cada célula da placa Elisa e 20 μL contendo 20 J2. Após 24 h contou-se o número de nematoides vivos e mortos. O pó de pequi moído foi testado em tomateiro em casa de vegetação em quatro doses (0; 7,5; 15 ou 30 g/4 kg de solo) em delineamento em blocos ao acaso com 10 repetições por tratamento. O pó de pequi foi incorporado sete dias antes do plantio do tomateiro e a inoculação de ovos do nematoide foi feita após o plantio. Após 40 dias foram avaliados: o número de galhas, massas de ovos, ovos por raiz e J2/200 cm³ de solo e altura e peso de massa seca de parte aérea do tomateiro. O extrato aquoso reduziu significativamente a eclosão e aumentou a mortalidade de J2 do nematóide das galhas. O aumento das doses do pó reduziu o número de galhas, massas de ovos e ovos do nematóide das galhas por sistema radicular, bem como o peso da massa seca de parte aérea e da altura do tomateiro os quais são indicativos de fitotoxicidade.The exocarp and external mesocarp of pequi fruit are discarded during the extraction of internal mesocarp which is the commercial part used as food. The objective of this research was to study the use of aqueous extract and of pequi ground-powder to the control of root-knot nematode (Meloidogyne javanica). From ground pequi fruit exocarp and external mesocarp were obtained the aquaeous extract and powder. Five doses of aquaeous extract (0.0; 2.5; 5; 10 or 20%) were evaluated on root-knot nematode J2 (second stage juvenile) hatching and mortality. The assays were carried out in entirely randomized design with 10 replications. The hatching assay was set in Petri plates with 800 nematode eggs and 10 mL of different doses of extract. During 14 days we counted the number of hatched juveniles under optical microscope. The mortality assay of root-knot nematode was evaluated putting 100 µL of each dose of extract plus 20 µL of supension containing 20 J2 in each cell Elisa plate. After 24 h was counted the number of live and dead juveniles. The pequi powder was tested in tomato plants in greenhouse in four doses (0; 7.5; 15 or 30 g/4 kg of soil) in randomized blocks design with 10 replications per treatment. The pequi powder was incorporated to the soil seven days before transplanting and nematode eggs inoculation was carried out after transplanting. After 40 days we evaluated the number of galls, egg masses, eggs/root and J2 per 200 cm³ soil and the tomato shoot dry weight and height. The aquaeous extract reduced J2 hatching and increased J2 mortality. The increased application of powder doses reduced the number of galls, egg masses and eggs of root-knot nematodes per root system and the tomato shoot dry weight being a good indication of phytotoxicity.

The effects of treating seeds of the common bean with rhizobacteria before sowing associated with different nitrogen (N) doses on the control of the nematode Meloidogyne javanica was evaluated. The assay was carried out in a greenhouse in random blocks, with a factorial arrangement of 5 × 5 + 1: five N doses (0, 25, 50, 100, and 200 kg/ha); five isolates: Bacillus pumilus (1, 60 and 76), Bacillus subtilis.-34, Bacillus sp.-36, and one control treatment. The plants were inoculated with 3,000 nematode eggs/pot. After 60 days the assay was evaluated. In the absence of N, B. pumilus-60 promoted a reduction of more than 50% in the number of galls and egg masses compared to the control. B. pumilus (1 and 76) and Bacillus sp.-36 reduced the number of galls in combination with increased N doses. Treatment of seeds with Bacillus in combination with N fertilization contributed to a reduction in the number of galls and nematode egg masses. B. pumilus (60 and 76) reduced the number of galls and egg masses in the absence of N, indicating a nematicidal effect. The treatments had no effect on the number of second-stage juveniles, eggs, or the plant parameters.

O cultivar Prata Anã é o mais plantada no Norte de Minas Gerais, o que demonstra estar a bananicultura regional baseada numa variedade suscetível à sigatoca-negra. Apesar de existirem cultivares resistentes em fase de recomendação para o cultivo na região, ainda são escassos os trabalhos relacionados a metodologias de conservação pós-colheita. Assim, o objetivo deste trabalho foi avaliar o período de armazenamento e as características físico-químicas e sensoriais dos cultivares de bananeira Fhia - 02 e Precioso, ambos resistentes à sigatoca-negra, e o efeito da atmosfera modificada associada à refrigeração. Foram realizados três experimentos, o primeiro em temperatura ambiente, o segundo a 12 ºC e o terceiro a 15 ºC. Esses experimentos foram instalados no delineamento em blocos casualizados em esquema de parcelas subdivididas no tempo, tendo nas parcelas um fatorial 2 (com e sem embalagem) x 2 (Fhia - 02 e Precioso) e nas subparcelas as avaliações em intervalo de seis e dois dias para frutos armazenados nas temperaturas de 12, 15 e 25 ºC, com quatro repetições e três frutos por unidade experimental. Após o tratamento, os frutos foram dispostos em bandejas de poliestireno expandido (sem embalagem) e embalagens de 10 e 16 µm e umidade relativa de 90%. As características avaliadas foram: tamanho, diâmetro, cor, firmeza, perda de matéria fresca, sólidos solúveis totais (SST), acidez total titulável (ATT), SST/ATT, pH e análise sensorial. O uso da embalagem associada à refrigeração permitiu armazenar os frutos por 28 dias, mantendo as características físico-químicas. The cultivar Prata Anã is widely grown in the North of Minas Gerais State, Brazil, hence, the banana business in the region is based on a variety susceptible to Black Sigatoka. Although there are resistant cultivars being recommended to cultivation in the region, studies related to post-harvest conservation are still scarce. The objective of the present work was to evaluate the storage period and physiochemical and sensorial characteristics of cultivars, Fhia - 02 and Preciosa, both resistant to Black Sigatoka, and the effect of the modified atmosphere associated with cooling. Three experiments were carried out, the first under ambient temperature, the second at 12ºC and the third at 15ºC, The experiments were arranged in randomized block design with split-plots in the time, having in the plots a 2x2 factorial (with and without packing) x (Fhia - 02 and Preciosa), and in the subplots the evaluations at six and two days, at 12, 15 and 25º C, with four repetitions and three fruits per experimental unit. After the treatment, the fruits were placed in expanded polystyrene trays (without packaging) and 10µm and 16µm packagings and relative humidity of 90 %. The evaluated characteristics were size, diameter, color, firmness, loss of fresh matter, total soluble solids (TSS), total titratable acidity (TTA), TSS/TTA, pH and sensorial analysis. The use of packaging associated with cooling allowed fruit storage for 28 days keeping its physical-chemical characteristics.

FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Alternative forms of disease control in fruits have been researched in an attempt to minimize the negative effects of chemical control on men and environment. The aim of this study was to determine the best concentration of essential oils to control the development of Colletotrichum musae and anthracnose intensity in ‘Prata Anã’ banana. In order to inhibit germination, mycelial growth and sporulation, four essential oils of clove (Eugenia caryophyllus), tea tree (Melaleuca alternifolia), thyme (Thymus vulgaris) and ginger (Zingiber officinale) species were used at concentrations of 2, 4, 6 and 8 μL. In fruits, the same essential oils were applied at concentrations of 80, 160, 240 and 320 μL to evaluate the incidence and severity of anthracnose. Clove and thyme oils were the most efficient in inhibiting mycelial growth, germination and sporulation at all concentrations tested. The volatile compounds present in clove and thyme oils provide complete inhibition of fungal growth. Tea tree and ginger oils have the ability to suppress anthracnose in ‘Prata Anã’ banana. Concentrations of 160 μL of ginger oil, 160 and 240 μL of tea tree oil reduced the anthracnose severity in fruits. Ginger and tea tree essential oils have the potential to control banana anthracnose, reducing the anthracnose incidence in fruits by 48% and 24%, respectively.

Alguns hibridos tetraploides apresentam resistência à antracnose, porém são reduzidas as informações sobre os níveis de resistência desses genótipos e o comportamento dos mesmos no Brasil. O objetivo do presente trabalho foi avaliar a incidência e a severidade de antracnose sobre o comportamento de diferentes genótipos de bananeiras resistentes a Sigatoka-Negra em função de diferentes concentrações de conídios de Colletotrichum musae em diferentes épocas de avaliação. Os frutos colhidos no estádio de maturação fisiológica dos genótipos, Thap Maeo, Caipira, Pacovan Ken, Ambrosia, PV 42-53, PA 42-44, FHIA 01, FHIA 18 e a cultivar Prata-Anã utilizada como testemunha. Buquês contendo três frutos foram atomizados com diferentes concentrações (0; 10²; 10³; 10(4); 10(5) e 10(6) conídios/mL) de C. musae. Os frutos foram incubados a 25 ºC. A incidência e severidade da antracnose foi avaliada aos 3; 6; 9 e 12 dias após a inoculação. Foi utilizado o delineamento inteiramente casualizado, em esquema fatorial 9x6x4 (genótipos, concentrações de esporos e épocas de avaliação), com quatro repetições, contendo quatro buquês de três frutos. Aos doze dias de avaliação, todos os frutos de todos os genótipos estudados apresentaram incidência de C. musae quando inoculados com as diferentes concentrações de inóculo. A cultivar Thap Maeo apresentou a menor severidade (27,5%) de antracnose, enquanto os genótipos Ambrosia, PV 42-53, FHIA 18 e FHIA 01 foram as mais suscetíveis à antracnose com 64%, 64%, 61,33% e 58% de severidade, respectivamente. Some tetraploides hybrids present resistance to anthracnose, however the information on the levels of resistance of these genotypes and the behavior in Brazil are reduced. The aim of this study was to evaluate the incidence and severity of injury on the behavior of different banana genotypes resistant to Black Sigatoka for different concentrations of conidia of Colletotrichum musae in different times of evaluation. The fruits of the genotypes, Thap Maeo, Caipira, Pacovan Ken, Ambrosia, PV 42-53, PA 42-44, FHIA 01, FHIA 18 and cultivar Prata Anã, were collected at the stage of physiological maturation. Bunches containing three fruits were atomized with different concentrations: 0, 10², 10³, 10(4), 10(5) and 10(6) conidia/mL of C. musae. The fruits were incubated at 25 ºC. The incidence and severity of the anthracnose were evaluated 3, 6, 9 and 12 days after the inoculation. A completely randomized experimental design was used, in a factorial scheme 9x6x4 (genotypes, concentrations of spores and evaluation periods) with four replications containing four bunches of three fruits. After twelve days of evaluation all the fruits of all the studied genotypes presented incidence of C. musae when different concentrations of inoculum were used. Concerning the severity of the anthracnose, the cultivar Thap Maeo had the lowest severity (27,5%) of anthracnose while the genotypes Ambrosia, PV 42-53, FHIA 18 and FHIA 01 were the most susceptible to the anthracnose at 64%, 64%, 61,33%, 58% of severity, respectively.

Pequi waste added to soil can lead to promising results in the management of plant nematodes. This study evaluated the effect of organic compost of pequi fruit waste in the control of Meloidogyne javanica in okra plants. The compost was comprised of cattle manure, sugarcane straw, and pequi rind waste in the ratio 1:1:1. Treatments were five doses of organic compost (0, 5, 10, 20, and 30 g dm-3) and two additional controls: manure (20 g dm-3) and mineral fertilizer (100 mg dm-3 of N), arranged in randomized block design with 10 repetitions. Different treatments were incorporated into pots containing 3 dm-3 of sandy soil infested with 5,000 eggs of M. javanica. Seedlings were transplanted five days later, and evaluated after 60 days of transplanting. Organic compost with pequi waste incorporated to soil increased shoot dry weight and root weight, and reduced the number of egg masses, galls and eggs of M. javanica per gram of root, and reproduction factor. Doses of 20 and 30 g dm-3 increased plant development and reduced the reproductivity of M. javanica compared to mineral fertilizer.

RESUMO A antracnose é uma das principais doenças pós-colheita em bananas. O trabalho teve como objetivos avaliar, durante dez meses, a intensidade da antracnose e o efeito da lavagem e sanitização das frutas no controle da doença em pós-colheita de bananas. O experimento foi realizado de setembro de 2013 a junho de 2014. As coletas dos frutos foram realizadas, mensalmente, em cinco propriedades comerciais localizadas nos municípios de Jaíba, Janaúba e Nova Porteirinha, cultivadas com banana ‘Prata-Anã’. As pencas foram subdivididas em buquês de três frutos, o delineamento experimental foi o inteiramente casualizado em esquema fatorial e submetidos aos tratamentos: frutos sem a realização da lavagem (testemunha); frutos lavados na propriedade; frutos lavados no laboratório com hipoclorito de sódio a 2%; frutos lavados no laboratório com hipoclorito de sódio a 2% seguido de aplicação com fungicida Imazalil. As avaliações foram realizadas em 10 épocas e os tratamentos repetidos cinco vezes. Calculou-se área abaixo da curva de progresso da intensidade (AACPI) e área abaixo da curva de progresso da severidade (AACPS). Os resultados obtidos foram submetidos à análise de variância e as médias comparadas através do teste de Scott-Knott, a 5% de probabilidade. A maior intensidade de antracnose em bananas no Norte de Minas ocorre nos meses de novembro de 2013 a março de 2014. A menor intensidade ocorre nos meses de setembro e outubro de 2013 e abril a junho de 2014. Nos meses de novembro a março, época de maior intensidade de doença, a lavagem dos frutos com detergente neutro e hipoclorito de sódio a 2% seguida de aplicação do fungicida Imazalil é a técnica mais eficiente de controle. A lavagem dos frutos, apenas com detergente neutro pode favorecer o aparecimento de antracnose, pela degradação da cutícula. ABSTRACT Anthracnose is one of the major post harvest diseases of bananas. The study aimed to evaluate for ten months the intensity of the anthracnose and the effect of washing and sanitizing of the fruits in the disease control on the post harvest of bananas. The experiment was conducted from September 2013 to June 2014. The samplings of the fruits were held monthly in five commercial properties located in the cities of Jaíba, Janaúba and Nova Porteirinha, cultivated with banana “Prata-Anã”. The bunch of bananas were subdivided into bouquets of three fruits, the experimental design was entirely randomized in factorial scheme and subjected to the treatments: fruits without the realization of the washing (control); fruits washed in the property; fruits washed in the laboratory with sodium hypochlorite at 2%; fruits washed in the laboratory with sodium hypochlorite followed by 2% Imazalil fungicide application. The evaluations were performed in 10 seasons, and the treatments replicated five times. It was calculated the area below the intensity progress curve (ABIPC) and the area below the severity progress curve (ABSPC).The results obtained were subjected to analysis of variance and average compared by the Scott-Knott test at 5% of probability. The highest intensity of anthracnose on bananas in North of Minas Gerais occurred in the months of November 2013 to March 2014. The lower intensity occurred in the months of September and October 2013 and from April to June 2014. In the months from November to March, period of higher intensity of the disease, the washing of the fruits with neutral detergent and sodium hypochlorite at 2% followed by application of Imazalil fungicide is the most efficient control technique. Washing of fruit, only with neutral detergent may increase the incidence of anthracnose, a deterioration of the cuticle.

A aplicação de novas tecnologias torna-se necessário para aumentar o período de comercialização da pinha (Annona squamosa ) que apresenta alta perecibilidade e vida útil curta. Com o objetivo de retardar a evolução do amadurecimento, as pinhas foram tratadas com 1-metilciclopropeno (1-MCP) nas concentrações de 0; 200; 400 e 600 nL L-1, durante 8 horas, a 25ºC. Posteriormente, os frutos foram armazenados a 15ºC, durante 21 dias. Em intervalos de sete dias, amostras foram retiradas da câmara para análises quanto à firmeza, perda de massa fresca, coloração (cromaticidade e ºHue), pH, sólidos solúveis (ºbrix), acidez titulável, relação sólidos solúveis/acidez titulável, teor de amido, açúcares totais, açúcares redutores e sacarose. Não houve efeito significativo dos tratamentos quanto ao pH, sólidos solúveis, acidez titulável, relação sólidos solúveis/acidez titulável, perda de massa fresca e sacarose, somente efeito de tempo de armazenamento. A acidez titulável não apresentou modelo estatístico que explicasse o efeito da época de armazenamento. Houve interação significativa da concentração de 1-MCP e dos dias de armazenamento em relação à firmeza, coloração, teor de amido, açúcares totais e açúcares redutores. Quanto maior a dose de 1-MCP aplicado, mais lenta foi a evolução do amadurecimento, sendo que a concentração de 600 nL L-1 foi a que melhor retardou o amadurecimento . The application of new technologies is necessary to increase the marketing period of 'pinha' (Annona squamosa), which is highly perishable and presents short shelf life. Aiming at retarding the maturation evolution, 'pinhas' were treated with 1-methylcyclopropene (1-MCP) at concentrations of 0, 200, 400 and 600 nL L-1 during 8 hours at 25ºC. Then, the fruits were stored at 15ºC for 21 days. The fruits were taken from the chamber at 7-day intervals to be analyzed as to firmness, weight loss, color (chromaticity and ºHue), pH, total soluble solids, titratable acidity, soluble solids/acidity relation, starch content, total sugars, reducing sugars and sucrose. There was no significant effect of the treatments on pH, soluble solids, titratable acidity, solid soluble/titratable acidity relation, fresh mass loss or sucrose, but there was only the effect of the time of storage. The titratable acidity did not present a statistical model to explain the effect of the time of storage. There was a significant interaction of the concentration of 1-MCP and the days of storage in relation to firmness, color, starch content, total sugars and reducing sugars. The higher the dose of 1-MCP applied, the slower the maturation evolution. The concentration of 600 nL L-1 was the best to retard maturation and extend the shelf life of custard apple.

As cultivares de bananeira mais plantadas no Brasil são suscetíveis às principais doenças da cultura, estando em curso a busca por variedades resistentes que possam substituí-las com boa aceitação dos produtores e consumidores. O objetivo deste trabalho foi avaliar as características físicas, químicas e sensoriais de frutos da bananeira 'Prata-Anã' e seu híbrido 'BRS Platina', armazenados a 15 ºC e a 25 ºC, ao longo do amadurecimento. O delineamento experimental foi o inteiramente casualizado, no esquema fatorial 2 (genótipos) x 2 (temperaturas) x 4 (estádios de maturação). Os frutos foram avaliados sensorialmente e quanto à coloração da casca, diâmetro, comprimento, resistência ao despencamento, firmeza, massa com e sem casca, espessura da casca, relação polpa/casca, sólidos solúveis, pH, acidez titulável, açúcares totais, açúcares redutores e amido. A 'BRS Platina' apresenta frutos com maior diâmetro, comprimento e massa, acidez semelhante e menor doçura em comparação à 'Prata-Anã'. O armazenamento a 15 ºC confere maior firmeza e resistência ao despencamento aos frutos de 'Prata-Anã' e 'BRS Platina', em comparação com o armazenamento a 25 ºC. Os frutos de 'BRS Platina' apresentam índice de aceitação satisfatório, porém inferior ao obtido para os de 'Prata-Anã'. Banana cultivars grown in Brazil are susceptible to major banana diseases, it has been underway to search for resistant varieties that can replace them with good acceptance by producers and consumers. This study aimed to evaluate the physical and chemical characteristics of banana fruits of 'Prata Anã' cultivar and its hybrids 'BRS Platina', stored at 15 ºC and 25 ºC. The experimental design was entirely at random in factorial scheme 2 (genotypes) x 2 (temperature) x 4 (ripening stage). The fruits were evaluated as for sensory analysis, and skin color, diameter, length, finger drop resistance, firmness, weight with and without skin, skin thickness, pulp/peel ratio, soluble solids, pH, acidity, total sugars and starch. The 'BRS Platina' genotype shows better characteristics with fruit size, it is similar as for acidity and lesser sweetness compared to 'Prata Anã' cultivar. Storage at 15 ºC increases firmness and resistance to dropping of 'Prata Anã' and 'BRS Platina' fruits in comparation to storage at 25 ºC. The 'BRS Platina' fruits had satisfactory level of acceptance, however lower than 'Prata Anã'.
