Abstract

The invention discloses a pesticide composition containing captan. The effective active components of the composition are captan, thiamethoxam and an active component C, the active component C is selected from azoxystrobin, carboxin, or metalaxyl, or metalaxyl-M, wherein the weight ratio of captan to thiamethoxam to the active component C is 1-80:1-80:1-80, and the composition can be prepared to a suspended seed coating agent. The composition can be used for preventing and treating soil insects and pathogenic bacteria, has obvious synergism effect, enlarges controlling spectrum, and has high activity for crop pests and pathogenic bacteria; the pests consist of aphids, midge, root-knot nematodes, wireworms, grubs, cutworms, thrips, mole crickets, athetis lepigone and borers, and diseases consist of sheath blight, bakanae disease, gummy stem blight, rust disease, stripe rust, root rot, head blight, powdery mildew, anthracnose, head smut and full rot. The composition has a sustained-release effect, the dosage of pesticides is reduced, and the composition is safe to human and livestock, is free from damage caused by chemicals and is good in environmental compatibility.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a captan-containing pesticide composition. Background technique [0002] Molecular formula of captan: 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] Thiamethoxam (thiamethoxam), chemical name: 3-(2-chloro-1,3-thiazol-5-ylmethyl)-5-methyl-1,3,5-oxadiazin-4-yl fork ( Nitro)amine, the drug is a new type of high-efficiency, low-toxicity broad-spectrum insecticide. It is a second-generation neonicotinoid insecticide, and its mechanism of action is similar to that of the first-generation neonicotinoid insecticides such as imidacloprid, but it has higher activity. It has the characteristi...
