Sterilization composition containing cyazofamid and pyraclostrobine and application thereof

Abstract

The invention belongs to the technical field of pesticide, and specifically relates to a sterilization composition containing cyazofamid and pyraclostrobine, and application of the sterilization composition in the aspects of controlling fungal diseases of crops. The weight ratio of cyazofamid to pyraclostrobine in the composition is 50:1 to 1:50; and by compounding, the composition has synergistic action, is wide in application range, low in cost and good in effect, can be used for controlling downy mildew, epidemic disease and other diseases generated by phycomycetes and other fungi on grape, cucumber, tomato, potato and other crops, has excellent control effect and simultaneously has better action on delaying the pesticide resistance of pathogenic bacteria.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a bactericidal composition compounded with pyraclostrobin and cyafamid, and its application in preventing and treating fungal diseases of crops. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, chemical name N-[2-[[1-(4-chlorophenyl)pyrazol-3-yl]oxymethyl]phenyl]-N - Methyl methoxycarbamate, a methoxyacrylate fungicide with a pyrazole structure, inhibits mitochondrial respiration by preventing electron transfer between cell pigment b and C1, interferes with cell energy supply, and causes cell death , thereby exerting a bactericidal effect. Pyraclostrobin has good protection, treatment, systemic conduction and resistance to rain erosion, and has a broad spectrum of sterilization, which is effective against almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes) It shows good activity; at the same time, it can have a po...

AI Technical Summary

Problems solved by technology

It has effects on all growth stages of oomycetes, and is active against metalaxyl-resistant or sensitive bacteria. It has certain systemic and therapeutic activity, long-lasting effect, resistant to rain erosion, and is safe for crops, humans, and the environment. However, long-term single use will inevitably make bacteria resistant to it

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the generation of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a large increase in dosage, shortened spraying cycle, and poor use effect, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products also increase, which affects the health and normal survival of humans and animals. The compound use of pyraclostrobin and Cyazofamid is used to prevent and control crop diseases. Not yet reported at home and abroad
