Problems solved by technology

[0003] At present, the commonly used seed treatment agent is solid powder, which needs to be ground into fine particles during the preparation process, which causes great difficulties in the processing of the seed treatment agent, and at the same time, a large number of particles will be produced floating in the air, which is harmful to people and The environment causes pollution and harm; once the particle size is too large or uneven, it will cause uneven seed dressing during use, resulting in a decline in the control effect
The process of preparation and processing is relatively cumbersome, requiring a lot of manpower, material resources, and financial resources, and it is inconvenient to use. Once the processing quality cannot be guaranteed, there will be a problem of reduced control effect

Abstract

The invention provides a hymexazol and capsaicine compound seed finishing agent and a preparation thereof. The seed finishing agent comprises 2 to10 wt. % of hymexazol, 1 to 5 wt. % of capsaicine, 10 to 35 wt. % of surface active agent, 10 to 30 wt. % of solvent, 1 to 5 wt. % of film-forming agent and 51 to 76 wt. % of water. The hymexazol and capsaicine compound seed finishing agent of the invention can prevent and cure seedling blight of paddy rice, can drive away injurious insects and mice, has less dose, high efficiency, quick absorption and strengthening drone function, greatly decreases the use dose, lowers the agricultural production cost and lessens the environmental pollution caused by using a large amount of medicine. A field trial of insecticide proves that the invention can excellently prevent injurious insects in the seedling stage of paddy rice and the field seedling preserving ratio is high.

Description

technical field [0001] The present invention relates to a seed treatment agent. technical background [0002] Due to safety and environmental considerations, the structure of pesticides is changing, and seed treatment agents are getting more and more attention in agricultural production. One of the main reasons is its high degree of targeting. Different from general field spraying and application, seed treatment concentrates the application of pesticides on crop seeds, thereby greatly reducing the amount of pesticides used. Compared with furrow application, 15% of it is not used for seed treatment; compared with foliar spraying, less than 1% of it is used for seed treatment. Therefore, seed treatment is an important way to reduce the amount of pesticide active substances, which is in line with the current general trend of the world. From the perspective of environmental protection, seed treatment agents are popular pesticide preparations. The fungicides used in seed treatm...
