Abstract

The present invention relates to a kind of suspending type biological seed coating agent and its preparation method and its application, which is concentrated by dispersant, film forming agent, antifreeze agent, coloring agent, preservative, insecticide, disease prevention type dormant somatic microorganism Composition of material and silicone defoamer. Compared with the existing chemical seed coating agent, the suspension-type biological seed coating agent of the present invention has good stability, short film-forming time, does not affect the germination rate of seeds, has remarkable effects of insect and disease prevention, and has a good effect of increasing yield, and is effective against root rot of corn seedlings. The disease control effect reaches 85‑96%, the control effect on underground pest cutworms and mole crickets reaches 20‑88.9%, and the production increase effect reaches 10‑30%.

Description

【Technical field】 [0001] The invention belongs to the technical field of biological pesticide control. More specifically, the present invention relates to a suspension-type biological seed coating agent, a preparation method of the suspension-type biological seed-coating agent, and an application of the suspension-type biological seed-coating agent. 【Background technique】 [0002] Soil-borne diseases at the seedling stage of field crops and underground insect pests are a very serious type of plant diseases and insect pests, and their incidence is increasing year by year, resulting in serious loss of grain crop yield and huge losses to the agricultural economy. Pre-sowing seed dressing with highly toxic and high-residue pesticides has been the main method for controlling seedling pests and diseases for many years. However, the long-term use of single chemical pesticides increases the resistance of diseases and insect pests and reduces the control effect; at the same time, it ...
