Title: tudy the antagonistic of the tomato's endogeny rayungus ts-6 on the Botrytis cinerea and it's control effect
Abstract: This article determined the antagonistic of the tomato's endogeny rayungus ts-6 on the Botrytis cinerea and it's control effect.The result indicated that,confronts raise the ts-6 strain has obviously antagonistic action on the botrytis cinerea hypha growth,after culture 7 day to be possible to form diameter 30mm the inhibitory zone,it can be reache to12 mm.Under the microscope the inhibitory zone edge mycelium abnormally expands obviously,the separation,the branching increase,the partial hyphas peak expands becomes the vesicle shape,some vesicles burst,thebioplasm revelation;Inhibition of metabolites of TS-6 to spore germination and mycelium growth of Botrytis cinerea,it shows that: its metabolites are both have the bacteriostasis ingredient which has the endurance of high temperature,and has the enzyme class bacteriostatics which is easy deactivation when it meets high temperature;Examination of the detached and the greenhouse preventing shows that,the effect of prevention of the ts-6 strain nutrient fluid on grey mould is well than the spore suspension and the sterile filtrate.When hours of inoculating pathogen after treatments is 24h,effect of preventing of sterile filtrate is well than spore suspension;When hours of inoculating pathogen after treatments is 48h,effect of preventing of the spore suspension is well than sterile filtrate.
