Abstract

The invention belongs to the field of pesticide bactericides and in particular relates to a bactericide compound composition containing difenoconazole and bismerthiazol. The composition is characterized in that the weight ratio of difenoconazole to bismerthiazol is (5:1)-(1:5); the weight percent contents of the active ingredients difenoconazole and bismerthiazol in the compound bactericide are 10-80%; and the rest ingredients are auxiliary ingredients which are allowed to be used and can be accepted in pesticides. The composition is mainly used for controlling watermelon gummy stem blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, heiyabing, citrus scab, rice bacterial leaf blight, cucumber target leaf spot and the like and has the characteristics of obvious synergy, bactericidal broad spectrum, long duration, safety for crops and the like.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a compound fungicide whose active ingredients are difenoconazole and ecloconazole. Background technique [0002] Difenoconazole is a broad-spectrum and high-efficiency fungicide, which mainly inhibits the biosynthesis of ergosterol in pathogen cells, thereby destroying the structure and function of cell membranes. It is mainly used in fruit trees, vegetables, wheat, potatoes, beans, melons and other crops , It has very good protective and therapeutic effects on various fungal diseases such as vegetables and melons and fruits. However, it has little mobility in soil and slowly degrades. It can control pear scab, apple spot defoliation, tomato drought blight, watermelon blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, black scab, citrus scab, etc. the [0003] Ectilazole (Yeqingshuang) is a systemic fungicide independently developed...
