Fusarium wilt seriously endangers banana production, it causes yield loss and even no yield. It is spread by soil and transportation of seedlings, and chlamydospores of its pathogen survive in soil for 30 years. It is very difficult for the disease to be controlled, and it is always the focus of the government, academic field and banana industry. The experts, scholars, and related practitioners of domestic and abroad have done extensive and deep related research for solving this hard issue. This paper reviewed the previous research progress from the occurrence and harm of banana Fusarium wilt, the relationship between plant rhizosphere microecology and soil-borne diseases, banana rhizosphere microecology and their effects and contributions in Fusarium wilt control. The paper proposed the research trends of the interaction mechanism between Fusarium wilt and banana rhizosphere microecology, strain screening scope and isolating incubation methods, development and application of biocontrol agents with high efficiency and strong stability, aiming to provide references for subsequent in-depth study of banana rhizosphere microecology, the excavation and innovation utilization of excellent biological control resources and the efficient control of banana Fusarium wilt.

【Objective】 This study was to clarify the induction effect of amino oligosaccharin, isotianil and Hezhizhuang organic water-soluble fertilizer to banana Sigatoka leaf spot and provide a theoretical and practical basis for the selection of inducers to control banana Sigatoka leaf spot.【Method】 The effects of four inducer resistances on the banana Sigatoka leaf spot were studied based on the foliar spraying, foliar spraying plus root pouring and root pouring treatments in field. 【Result】Four resistant inducers had better effect on banana Sigatoka leaf spot under three induction treatments. Especially, the effect of foliar spraying plus root pouring treatment was the best and the induction effects of 5 % amino oligosaccharin AS, 20 % isotianil SC, 77 % isotianil WG and Hezhizhuang organic water-soluble fertilizer were 70.02 %, 72.62 %, 63.61 % and 67.67 % 7 days after the third induction, respectively. Moreover, the average induction effects of 5 % amino oligosaccharin AS, 20 % isotianil SC, 77 % isotianil WG and Hezhizhuang organic water-soluble fertilizer were 53.18 %, 56.68 %, 42.16 % and 53.34 % four surveys after the third induction, respectively. Then induced effects of 20 % isotianil SC, Hezhizhuang organic water-soluble fertilizer applied foliar spraying, root pouring were above 63 % 7 days after the third induction. Furthermore, the average control effect of Hezhizhuang organic water-soluble fertilizer applied root pouring was 52.33 % four surveys after the third induction. Hezhizhuang organic water-soluble fertilizer applied root pouring fell the least, followed by Hezhizhuang organic water-soluble fertilizer, 20 % isotianil SC and 5 % amino oligosaccharin AS applied foliar spraying plus root pouring, lasted above 28 days. In addition, 77 % isotianil WG applied root pouring fell the most, lasted only 7 to 14 days, the other treatments were 14 to 21 days. 【Conclusion】5 % amino oligosaccharin AS, 20 % isotianil SC and Hezhizhuang organic water-soluble fertilizer applied foliar spraying plus root pouring, Hezhizhuang organic water-soluble fertilizer applied root pouring had the strong inducing effects against banana Sigatoka leaf spot and the duration of the induced resistance could remain at least 28 days.
