Abstract

A disclosed compound sterilization composition containing oxathiapiprolin comprises an active component A and an active component B according to the weight ratio of 1:80-60:1, the active component A is oxathiapiprolin, and the active component B is selected from any one of the following compounds: metalaxyl, metalaxyl-m, propamocarb, propamocarb hydrochloride, cymoxanil and iprovalicarb. The composition has relatively high activity on multiple diseases of multiple crops, has obvious synergic effect, is expanded in bactericidal spectrum, and also has the characteristics of small drug usage amount, resistance to rain washing and obvious synergic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a compound bactericidal composition containing thiazolidinone to crop diseases. technical background [0002] Fluthiapiprofen is a new type of fungicide, which has remarkable control effect on downy mildew and blight. [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, the compounding effects of pesticides are additive effects, and there are very few compoundings that really have synergistic effects, especially those with very obvious synergistic effects and high synergistic ratios.
