Abstract

The invention discloses a high-efficient bactericidal composition containing hexamethylene flusulfamide. The composition comprises an active component A and an active component B, wherein the active component A is selected from hexamethylene flusulfamide, the active component B is any one compound selected from the following compounds: triazolone, pyrimidine nucleotide antibiotic, JS399-19, and bromothalonil, and the weight ratio of the active component A to the active component B is 1:60 to 80:1. The composition has a high activity on a plurality of pest diseases on a plurality of crops, has a prominent synergetic effect, enlarges the bactericidal spectrum, and has the characteristics of little drug using amount, rain washing resistance, and prominent synergetic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition containing cyclohexasulfame to crop diseases. technical background [0002] Cyclohexasulfame chemical name: N-(2-trifluoromethyl-4-chlorophenyl)-a-oxocyclohexylsulfonamide. It has strong preventive, therapeutic and osmotic activities, and has high persistence. The field test results show that cyclazone can effectively control Botrytis cinerea, rape sclerotinia, cucumber brown spot and scab. [0003] In the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases,...
