Fungicidal composition containing chesulfamide and zoxamide and application of composition

Abstract

The invention discloses a fungicidal composition containing chesulfamide and zoxamide and application of the composition. According to the fungicidal composition, chesulfamide and zoxamide serve as main effective components, and the mass ratio of chesulfamide to zoxamide is 1:50-70:1. The fungicidal composition can be applied to preventing diseases of cereal, fruit trees and vegetables, has a high synergistic function, overcomes and delays the insecticide resistance of germs, is high in fungicidal speed and long in lasting time, reduces the application cost, and has the prevention effect which is obviously better than that of single fungicides in use. The fungicidal composition can be used for preventing fungal diseases on crops, can be particularly used for preventing gray mold, scab, brown patch, sclerotiniose, sheath blight, late blight, downy mildew and other fungal diseases, and has effects better than those of the single fungicides in use.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with cyclazone and benzamid as main active ingredients and its application. Background technique [0002] Cyclohexasulfam chemical name: N-(2-trifluoromethyl-4-chlorophenyl)-α-oxocyclohexylsulfonamide. It has strong preventive, therapeutic and osmotic activities, and has high persistence. The field test results show that it can effectively control Botrytis cinerea, rape sclerotinia, cucumber brown spot and scab. [0003] Zoxamide, molecular formula: C 14 h 16 Cl 3 NO 2 . The chemical name is: 3,5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-4-methylbenzamide. The mechanism of action of benzamid is very unique among oomycete fungicides. It inhibits sclerotin division through the binding of tubulin β-subunit and the rupture of microtubule cytoskeleton. Benhexamid did not affect zoospore motility, cyst formation or germination...

AI Technical Summary

Problems solved by technology

[0004] At present, the prevention and control of plant pathogens is becoming more and more difficult. The main reasons are as follows: First, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased. The second is that the current climate is abnormal, which provides certain conditions for the outbreak of the disease; the third is the long-term selective influence of chemical drugs, which makes the resistance of pathogenic bacteria increase year by year under the pressure of continuous drug selection. The effect is greatly reduced

In summary, the current plant disease control is facing major challenges
