Abstract

The invention discloses an insecticidal and disease-preventing suspended seed coating agent which is mainly characterized in that effective active components are fludioxonil and an effective component B, wherein a weight ratio of fludioxonil to the effective component B is 1:60-60:1. The composition is prepared into the suspended seed coating agent. The suspended seed coating agent provided by the invention has the advantages of good film-forming performance, uniform coating, high suspension rate, good safety, low toxicity, and the like. The suspended seed coating agent can be widely applied in seed treatments of crops such as wheat, corn, paddy rice, peanut, cotton, and the like. The seed coating agent has a sustained-release effect, such that pesticide dose is reduced. The seed coating agent is safe to human and animals, has no phytotoxicity, and has good environmental compatibility.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a suspension seed coating agent for killing insects and preventing diseases. Background technique [0002] Fludioxonil (fludioxonil), chemical name: 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1-hydrogen-pyrrole-3-carbonitrile, molecular formula :C 12 h 6 f 2 N 2 o 2 , the drug is a broad-spectrum contact fungicide, used for seed treatment, and can prevent and control most of the fungal diseases that are carried by seeds and soil. It is stable in the soil and forms a protective zone in the rhizosphere of seeds and seedlings to prevent the invasion of pathogens. The structure is new, and it is not easy to cross-resistance with other fungicides. [0003] Clothianidin, chemical name: (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-2-nitroguanidine, molecular formula: C 6 h 8 ClN 5 o 2 S, Fludioxonil is a neonicotinoid insecticide. It is a new type of insectici...
