Problems solved by technology

[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 are also increasing, which affects the health and normal survival of humans and animals. The compound use of kasugamycin and cyazazole is used to prevent and control crop diseases. Domestic Not yet reported

Abstract

The invention belongs to the technical field of pesticides, in particular to a complex bactericidal composition containing kasugamycin and cyazofamid and an application thereof in the aspects of controlling fungal and bacterial diseases of crops. The weight ratio of kasugamycin to cyazofamid in the composition is that kasugamycin: cyazofamid is equal to 1:1-1:100, the composition plays the synergy through complexing, has the advantages of a wide range of applications, low cost and good effects and can be used for controlling downy mildew, blight and other diseases of grapes, cucumbers, tomatoes, potatoes and other crops caused by phycomycetes and other fungi, as well as bacterial diseases, such as bacterial angular leaf spot of cucumber, the controlling effects are good, and the composition simultaneously has the better role of retarding the drug resistance of pathogens.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a bactericidal composition compounded with kasugamycin and cyafamid, and its application in preventing and treating fungal and bacterial diseases of crops. Background technique [0002] The chemical name of Cyazofamid is 4-chloro-2-cyano-5-p-methylphenyl-imidazole-1-N, N-dimethylsulfonamide, which belongs to imidazole fungicides. Cyazofazol is a mitochondrial respiration inhibitor, which 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, and is resistant to rain erosion. , safe for crops, humans, and the environment, but long-term single use will inevitably make bacteria resistant to it. [0003] Kasugamycin is also known as kasugamycin, and its chemical name is 5-amino-2-methyl-6-(2,3,4,5,6-carbonylcyclohexyloxy)pyran-3 -Amino-a-iminoacetic aci...
