Abstract
The invention discloses a pesticide composition containing carboxin. The composition is mainly characterized in that effective active constituents of the composition comprise carboxin and effective component B, the effective component B is selected from the group consisting of thiamethoxam, thiacloprid, imidacloprid and clothianidin, a weight ratio of carboxin to the effective component B is 1: 80 to 40: 1, and a suspended seed coating agent is prepared from the composition. The composition provided by the invention can be used for preventing and treating a variety of soil pests and pathogens, produces an obvious synergistic effect, has an expanded prevention and treatment spectrum and shows high activity to pests and pathogens on wheat, corn, sorghum and cotton, wherein wheat, corn, sorghum and cotton diseases include corn head smut, wheat smut, wheat rust, millet smut, loose kernel smut of sorghum, head smut, damping-off of cotton and cotton verticillium wilt; furthermore, the composition has a sustained release effect, reduces the dosage of a pesticide, is safe to people and livestock, produces no phytotoxicity and has good environmental compatibility.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to a pesticide composition containing wisterin. Background technique [0002] Carboxin, chemical name: 5,6-dihydro-2-methyl-1,4-oxathia-3-formylanilide, molecular formula: C 12 h 13 NO 2 S, Carboxyl is a heterocyclic fungicide with systemic effect. The pure product is white needle crystal. Insoluble in water, soluble in methanol, acetone, benzene and other organic solvents. It is easy to decompose and fail when encountering alkaline substances. Dosage forms include wettable powder, emulsifiable concentrate, etc. It is mainly used to prevent and control cereal smut such as sorghum head smut, and can also prevent and control wheat rust, cotton grass disease, and millet disease. Low toxicity to humans and animals, mice orally LD503200mg / kg. [0003] The long-term use of a single agent of wisterin will easily cause the disease to develop drug resistance, leading to problems such...
