Abstract

The invention relates to a bactericide composition for control of corynespora cassiicola, with synergism, of crops. The composition is composed of two or three active substances, wherein A component is diethofencarb, and B and C components are any one of azoxystrobin, pyrimethanil, prochloraz, hexaconazole, cyprodinil, fluazinam, boscalid, fludioxonil, mancozeb and chlorothalonil. In a binary composition AB, the weight ratio of diethofencarb to another bactericide is 99-1:1-99. In a ternary composition ABC, the weight ratio of A, B and C is 1-50:1-50:1-50. The other components are auxiliary components which are allowed to be used and acceptable in pesticides. The bactericide composition can be prepared into wettable powder, missible oil, suspending agents, water dispersible granules, emulsion in water and microemulsion. The bactericide composition has obvious synergism, has multiple action mechanisms and acting sites and can delay the occurrence of resistance to drugs of pathogens.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a fungicide composition for preventing and treating Corynespora leaf spot. Background technique [0002] Corynespora cassiicola is an important plant pathogenic fungus, which can parasitize vegetables, trees and ornamental crops in tropical and subtropical regions. From 2005 to now, in the field survey on the damage of Corynesporium leaf spot on vegetables in my country, it was found that 19 provinces including Shandong, Hebei, Beijing, Liaoning, Jilin, Henan, Yunnan and Hainan had serious outbreaks of the disease, mainly affecting cucumber, eggplant and tomato. Vegetables such as beans, kidney beans, and economic crops rubber, the area of ​​occurrence exceeds 10 million mu every year, and the loss exceeds 5 billion. Corynespora multiprimum has the characteristics of wide range of hosts, strong infestation and destructive power, wide transmission route, easy mutation, and lack of contro...
