Problems solved by technology

However, syringstrobin is a methoxyacrylate compound with a single mechanism of action. Long-term repeated use in field applications may lead to selectivity of fungal strains in many cases, and the strains form adaptive resistance to syringstrobin, resulting in The control effect of syringstrobin against these fungi is reduced or even ineffective, causing the disease to expand and spread, crop yield reduction, and pesticide waste

Abstract

The invention belongs to the field of agricultural chemical bactericides, and discloses an agricultural antifungal composition which is characterized by comprising components A and B, wherein the component A is coumoxystrobin, the component B is a compound selected from triazole bactericides, and the weight ratio of A to B is 1:40-40:1. The composition weakens or retards the generation of resistance of pathogenic fungi to the coumoxystrobin, and avoids the reduction of drug effect resulted from the resistance. Simultaneously, because heterogeneous fungicides form synergism of the composition,the control effect of the composition on diseases is remarkably improved. The composition can be prepared into the formulations of suspending agents, aqueous emulsion, wettable powder or microemulsion, and the like, and is applied to the controlling sclerotinia rot of colza, apple tree canker, rice blast, tomato leaf mold, wheat scab, cucumber scab, tomato anthracnose, cucumber blight, apple ringrot, rice sheath blight, rice bakanae disease, wheat powdery mildew, cucumber powdery mildew, cucumber downy mildew, wheat sheath blight, cucumber gray mold, banana gray pattern disease, and the like.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fungicides, in particular to an agricultural fungicidal composition containing syringstrobin and triazole fungicides. Background technique [0002] [0003] The Chinese common name of formula I compound is syringstrobin, chemical name: [0004] E)-methyl2-(2-((3-butyl-4-methyl-2-oxo-2H-chromen-7-yloxy)methyl)phenyl)-3-methoxyacrylate(E)-2-(2-((3 -Butyl-4-methyl-coumarin-7-yloxy)methyl)phenyl)-3-methoxymethyl acrylate is an efficient and broad-spectrum agricultural fungicide. Rapeseed sclerotinia, apple tree rot, rice blast, tomato leaf mold, wheat head blight, cucumber scab, tomato anthracnose, cucumber wilt, apple ring spot, rice sheath blight, rice bad seedlings Pathogens such as wheat powdery mildew, cucumber powdery mildew, cucumber downy mildew, wheat sheath blight, cucumber gray mold, and banana gray spot have very high antibacterial activity, (Chinese patent application number 2004...
