Abstract

The invention discloses a sterilization composition containing penthiopyrad. The sterilization composition contains an active component A and an active component B, wherein the active component A is selected from penthiopyrad; the active component B is selected from any one of the following compounds: cymoxanil, dimethomorph, propamocarb or a salt thereof, iprovalicarb, captan, chlorothalonil, metalaxyl or a salt thereof; the weight ratio of the component A to the component B ranges from (1:80) to (60:1). The composition has a synergistic effect on a plurality of types of diseases which endanger agricultural production; the dosage of pesticides is reduced; the residual amount of the pesticides on crops is reduced and the environmental pollution is alleviated; the composition is safe to human and livestock and has good environment compatibility, and drug resistance of the diseases is not easy to cause.

Description

[0001] This application is a divisional application. The original application is an invention patent submitted by Shaanxi Meibang Pesticide Co., Ltd. The original application name is "a fungicidal composition containing penthiopyram", the application number is "201210342423.2", and the application date is For: 2012.09.14. technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing penthiopyrad on crop diseases. Background technique [0003] Penthiopyrad (Penthiopyrad) Chemical Name: (RS)-N-[2-(1,3-Dimethylbutyl)-3-thiophenolyl]-methyl-3-(trifluoromethyl)- 1H-pyrazole-4-carboxamide, molecular formula: C 16 h 20 f 3 N 3 OS, Penthiopyrad is a new type of amide fungicide developed by Mitsui Chemicals, Japan. It has a different bactericidal spectrum from the existing carboxamide fungicides, except that it is as effective as the existing carboxamide fungicides against basidiomycetes ...
