Abstract

The invention discloses a bactericidal composition containing isothiazolone. The bactericidal composition containing the isothiazolone comprises effective active ingredients including a first active ingredient isothiazolone and a second active ingredient strobilurin fungicide, wherein the second active ingredient strobilurin fungicide is selected from azoxystrobin, kresoxim-methyl, pyraclostrobin, trifloxystrobin and orysastrobin, and the weight ratio of the first active ingredient to the second active ingredient is 1:100-5:1 and preferably is 1:50-1:1. The bactericidal composition can be prepared into microemulsion, suspension emulsion and paste which are allowable agriculturally. The bactericidal composition is reasonable in ingredients, good in bactericidal effect and low in pesticide cost, and the activity and the bactericidal effect are not produced by simple superposition of activity of the ingredients. Compared with existing single preparations, except the remarkable bactericidal effect, the bactericidal composition has remarkable synergistic effect, is free of pollution to crops and good in safety, meets the safety requirements for pesticide preparations and has remarkable prevention and control effect on rotten diseases of apple trees, rice blast and banded sclerotial blight of rice.

Description

technical field [0001] The present invention relates to a bactericidal composition containing isothiazolinone, especially an isothiazolinone as the first active ingredient selected from azoxystrobin, kresoxim-methyl, pyraclostrobin, trifloxystrobin, and oxime The methoxyacrylate fungicides of kresastrobin and syringstrobin as the second active ingredient belong to the technical field of compound pesticides. Background technique [0002] Isothiazolinone is a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI), technical indicators Implement the industry standard HG / T 3657-2008, product name: CIT / MIT, Kathon, Kathon, Kathon. Isothiazolinone is a broad-spectrum, high-efficiency, low-toxicity, non-oxidative biocide that kills bacteria and algae by breaking the bonds of proteins. After contacting with microorganisms, isothiazolones can quickly and irreversibly inhibit their growth, resulting in the death of microbial cells, and have st...
