Environment-friendly dispersible oily seed treatment agent and preparation method thereof

Abstract

The invention discloses an environment-friendly dispersible oily seed treatment agent and a preparation method thereof, and belongs to the technical field of pesticide seed treatment agents. The seedtreatment agent comprises the following components in percentage by weight: 50%-90% of benfuracarb or carbosulfan, 5-10% of an emulsifier, 0.1-5% of a film forming agent and the balance of an oily environment-friendly solvent. The environment-friendly dispersible oily seed treatment agent provided by the invention is high in physical and chemical stability; a pesticide film is uniform and does noteasily fall off; problems of adhesion and unsmoothness are avoided after seeds are coated; the seed treatment agent not only can be independently used, but also can be mixed with other water-based preparations for use; compatibility is high; safety and environment friendliness are achieved; and the application value is high.

Description

technical field [0001] The invention belongs to the technical field of pesticide seed treatment agents, in particular to an environment-friendly dispersible oily seed treatment agent and a preparation method thereof. Background technique [0002] Seed treatment is the most economical and effective method in the control of plant diseases and insect pests. It plays an important role in the prevention and control of plant diseases and insect pests in the seedling stage and the entire growth period. It uses less medicine, has good effects, has little impact on humans, animals and the environment, and has a long duration. , no matter in terms of economy, health, and efficacy, it is of great significance to agricultural production, and has become an important means of crop protection recognized internationally. [0003] Seed treatment agents are made from pesticides (insecticides, fungicides, etc.), fertilizers, growth regulators, film-forming agents and supporting auxiliaries thr...

AI Technical Summary

Problems solved by technology

[0004] At present, the dosage forms of seed treatment agents mainly include suspension seed coating agent, dispersible powder for seed treatment, dry powder for seed treatment, etc., the content of which is relatively low, most of which are below 40% (between 10% and 30%). Water-based or mixed with water, and in order to reduce costs, most domestic seed companies do not have a drying process after coating, which will cause the water content of the coated seeds to exceed the standard, which will cause the respiration of the seeds to increase during storage , produce mildew, it is difficult to meet the national standard

In addition, due to the limitation of the amount of water added to the seeds during the coating process, the water evaporates rapidly during the coating process, which often causes the seed treatment agent to form an uneven drug film on the surface of the seeds, and the shedding rate increases, which seriously affects the quality of the seeds after coating. Moreover, after the coating of some seeds is completed, due to the addition of a water-based film-forming agent, the seeds will stick together, the seeds will be sticky, astringent, and have poor fluidity, which is not conducive to the seeds to be packaged
