Seed treating agent based on insect viruses and thiamethoxam

Abstract

The invention relates to a seed treating agent based on insect viruses and thiamethoxam. The seed treating agent is prepared by mixing the following materials by weight percent: 0.001-96.9 percent of insect-virus particle technical material, 0.1-96.999 percent of thiamethoxam, 1-5 percent of adhesive fixing agent and 1-10 percent of suspension auxiliary agent. The seed treating agent is prepared by mixing the insect viruses and the thiamethoxam, not only utilizes the high-efficiency contact-poisoning effect of the thiamethoxam, but also utilizes high biocompatibility, nutrition, long action, continuity, amplification and replication of the insect viruses so as to achieve the effect of forming a virus insect-resistant area and achieve the purposes of high efficiency, environmental protection, economy and long action; and compared with the seed treating agent prepared by singly using the thiamethoxam, the seed treating agent has the advantages that the emergence rate is increased by 10-20%, the incidence rate and insect attack rate of seedlings of the treated seeds are reduced by 10-20%, and the yield is increased by 10-20%.

Description

technical field [0001] The present invention relates to a seed treatment agent based on insect virus and thiamethoxam. Background technique [0002] Seed coating agents, seed dressing agents and seed soaking agents are collectively referred to as seed treatment agents. Seed coating refers to wrapping the dry and wet plant seeds with a composition such as pesticides or fertilizers containing binders to form a protective layer with certain functions and wrapping strength. This process is called seed coating, and the original composition wrapped in the seed is called seed coating agent. If the medicament only forms a weak adsorption layer on the outer layer of the seed, it is called a medicament seed dressing agent. The powder seed dressing agent is also called seed powder coating agent. Seed soaking with liquid medicine is called seed soaking agent. The active ingredients of seed treatment agents are usually insecticides, fungicides, rodenticides, plant growth regulators, ...

AI Technical Summary

Problems solved by technology

Although thiamethoxam has the above-mentioned advantages, it has the disadvantages of poor biocompatibility as a chemical pesticide, short persistence, especially unstable to alkaline environment, and most microorganisms in the soil can degrade it, etc.
