Backgraund: The presence or absence of fungi on the seed surface is an important aspect that determines the quality of seeds. Since the data on the presence of Fusarium spp. and other seed-borne pathogens on vegetable pea in Serbia are scarce, the aim of this study was to isolate seed-borne pathogens and identify the disease-causing Fusarium spp. from the infected pea seed. Methods: Colony morphology and microscopic characters of isolated Fusarium species were recorded from the cultures grown on PDA and CLA, respectively. In order to confirm the morphological identification at the species level, a single-spore culture of the representative isolates was subjected to genomic DNA extraction and gene amplification using the translational elongation factor 1α (TEF-1) region. The PCR products were sequenced and the sequences were compared against the GenBank nucleotide database by using the BLAST alignment. Result: Based on morphological and microscopic characteristics, as well as molecular identification by sequencing the TEF gene, the presence of Fusarium equiseti and F. proliferatum was confirmed on the representative isolates Ps18, Ps19 and Ps1, Ps36 obtained from vegetable pea seeds, respectively. According to our knowledge and research, this is the first report of F. equiseti and F. proliferatum on vegetable pea seeds in Serbia. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the efficacy of tau - fluvalinate and lambda - cyhalothrin based insecticides in the control of P. rapae and P. xylostella caterpillars. In the agroecological conditions of Vojvodina province (Serbia) (localities Futog and Čurug) the production of cabbage is present every year at vast areas. During 2011, the experiments were performed according to a standard EPPO (PP PP 1/83 (2) 2004) method. The applied preparations are based on tau - fluvalinate (240 g of a.s. /l of the preparation) Mavrik - EW in amount of 0.3 l/ ha, and lambda - cyhalothrin (25 g/l of the preparation) Grom, in the amount 0.4 l/ha. The assessment of pests population abundance was performed before the treatment, two i.e. four and seven days after the treatment. The efficacy of insecticides was determined according to Henderson and Tilton and significance of differences by ANOVA.The average number of P. rapae caterpillars (25 plants/repetition) in Futog site before the treatment was 4.7 - 6.2, after four days it was 0-0.2 and after seven days 0.25-1.25, regardless on the applied insecticides, while the number in the control was 7.7 after four and 10.2 after seven days. Efficacy of insecticides at this site after four days ranged from 96.4 to 100 % and after seven days 89.8 - 97.3 %. At Čurug locality, the number of P. rapae caterpillars before the treatment was 9.7 - 12, while after two and seven days it ranged from 0.5 to 0.75, whereas in the control it was 11.5 after two and 11 after seven days. At this site, two days after the treatment, the efficacy ranged from 93.8 to 95.3 %, and after seven days from 92.7 to 96 %. The average number of P. xylostella caterpillars at locality Futog before the treatment was 13.5 -17.7. Four days after the treatment it was 1.75 - 2.25, and after seven days 1-1.25, while in the control it was 23.0 after four and 27.2 after seven days. At site Čurug before the treatment the average number of P. xylostella caterpillars ranged from 14 to 16.7. Two days after the treatment the average number ranged from 0.75 to 1, and after seven days 0-0.5, regardless on the applied insecticides, while in the control it was 13.0 after two days and 10 after seven days. The efficacy of tested insecticides for controlling P. xylostella caterpillars at Futog site ranged from 87.3 to 92.1 %, after four, and 94.1- 96.2 % after seven days. At Čurug, the efficacy ranged from 92.7 to 95.2 %, after two days and 95.3 to 100 % after seven days. By choosing insecticides based on tau-fluvalinate and lambda-cyhalothrin, in addition to satisfactory efficacy in the control of harmful caterpillars of cabbage, the applied amounts of a pyrethroids, compared to organophosphorus insecticides are far smaller i.e. 79 g and 10 g a.s./ha (respectively).
