Abstract
[Objective] The aim was to determine the control effect of 68.75% Fluopicolide propamocarb SC applied in different periods on Phytophthora capsici and its safety.[Method] With Zhongjiao 7 as tested material and P.capsici as control object,the control effect of several fungicides applied in different periods on P.capsici were studied.[Result] 68.75% Fluopicolide propamocarb SC had good control effect on P.capsici,and it was safe to Capsicum annuum at the experimental dosages and had no phytotoxicity.The fungicides applied in different periods had different controlling effect on P.capsici and the optimum way for controlling P.capsici was that applying fungicides in seeding stage combined with fungicide spraying in field after transplanting.72.2% Propamocarb hydrochloride AS at 43 320 g/hm2 was suggested to irrigate seedbed in seedling stage or 68.75% Fluopicolide propamocarb SC at 17 187.5 g/hm2 was applied for pouring root or root-irrigation before transplanting.68.75% Fluopicolide propamocarb SC at 773.44-1031.25 g/hm2 was suggested to spray stem in the early stage.The fungicides were applied once every 7 days and could be sprayed 2-3 times continuously.[Conclusion] The research provided the scientific basis for controlling P.capsici.
