Bactericidal composition containing isofetamid and captan

Abstract

The invention discloses a bactericidal composition containing isofetamid and captan and application of the bactericidal composition. An effective active ingredient is composed of a first active ingredient of isofetamid and a second active ingredient of captan, and the weight ratio of the first active ingredient to the second active ingredient is (1 to 70) to (70 to 1), preferably (1 to 50) to (50to 1). The bactericidal composition can be prepared into agriculturally acceptable agent forms of wettable powder, water dispersible granules, suspending agents, suspension emulsions, emulsions in water and microemulsions. The bactericidal composition is reasonable in components and good in bactericidal effect, and the activity and the bactericidal effect are not a simple superposition of the activity of the components; and compared with an existing single preparation, the bactericidal composition has the significant bactericidal effect and a significant synergistic effect, and is good in cropsafety. The bactericidal composition has significant control effects on crop gray mold, sclerotinia, venturia inaequalis and ring rot.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient iprotianil, a second active ingredient captan and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Isoprofen, the English name is isofetamid, the chemical name is N-[1,1-dimethyl-2-(4-isopropoxy-o-tolyl)-2-oxoethyl]-3- Methylthiophene-2-carboxamide. An amide fungicide developed by Ishihara Sangyo Co., Ltd. in Japan, it mainly acts on succinate dehydrogenase in pathogenic bacteria and inhibits its respiration to play a role. In 2014, it was launched in the United States by Summit Agro, and it is used to prevent Botrytis cinerea and Sclerotinia caused by Botrytis cinerea. [0003] Captan, English common name: captan, chemical name: 3a, 4, 7, 7a-tetrahydro-2-(trichloromethylsulfur)-1H isoindole-1,3-(2H)-dione. It can prevent and control a variety of diseases on fruit trees, vegetables and crops, a...
