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 discloses a composition containing coumoxystrobin and a related bactericide. The composition contains coumoxystrobin and fenamidone, zoxamide or proquinazid. Through combination of two bactericides with different action mechanisms, pathogenic fungus resistance to coumoxystrobin is reduced. Through synergism, disease prevention effects are substantially improved. An observation result shows that the wheat powdery mildew prevention and treatment efficiency of the composition is 128.89% higher than that of coumoxystrobin, 142.92% higher than that of fenamidone, 156.69% higher than that of zoxamide and 149.78% higher than that of proquinazid, rice blast prevention and treatment efficiency of the composition is 155.07% of that of coumoxystrobin, 271.42% higher than that of fenamidone, 385.52% higher than that of zoxamide and 225.34% higher than that of proquinazid, and apple tree canker prevention and treatment efficiency of the composition is 150.45% higher than that of coumoxystrobin, 181.52% higher than that of fenamidone, 215.62% higher than that of zoxamide and 147.20% higher than that of proquinazid.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fungicides, and in particular relates to a composition containing syringstrobin and related fungicides, wherein the other fungicides are one of imidaclomidone, benzamid and propoxyquinoline . Background technique [0002] The structural formula of syringstrobin is as follows: [0003] [0004] Syringstrobin 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 Blight, wheat powdery mildew, cucumber powdery mildew, cucumber downy mildew, wheat sheath blight, cucumber gray mold, banana gray spot and other pathogens have high antibacterial activity, (Chinese patent application number 200480020125.5). However, syringstrobin is a methoxyacrylate compound with a single mechanism of action. Long-term...
