Abstract

The invention discloses a sterilization composition containing captan and a copper preparation. The effective active components are an active component A and an active component B, wherein the active component A is captan, the active component B is any one of the following copper preparations: cuppric nonyl phenolsulfonate, copper oxychloride, copper dicarboxylate, and cupric acetate, and the weight ratio of the active component A to the active component B is 1:80-80:1. The composition has synergism effect for a plurality of diseases which are harm to agricultural production, reduces pesticide usage amount, reduces residual amount of the pesticide on crops, mitigates environment pollution, and is safe to people and livestock, the environment compatibility is good, and pesticide resistance for disease is not easily generated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing captan and copper preparations on crop diseases. Background technique [0002] Captan chemical name: 3a,4,7,7a-tetrahydro-2-(trichloromethylsulfur)-1H isoindole-1,3-(2H)-dione, molecular formula: C 9 h 8 Cl 3 NO 2 S, Captan can prevent and control various diseases on fruit trees, vegetables and crops, and can also be used as a seed treatment agent or root irrigation to prevent stem blight, blight, and black spot. It is phytotoxic to certain varieties of apples and pears, and has effects on lettuce, celery, and tomato seeds. [0003] Copper nonyl, copper king, copper succinate, and copper acetate are all copper preparations, which are widely used in crop diseases. Copper oxide can also be compounded with captan. [0004] However, in the actual process of agricultural production, the most likely problem in disease cont...
