[0002] Seeds and seedlings are vulnerable to damage and infection by various underground and above-ground pests and pathogenic bacteria, and are the most vulnerable link in the growth process of crops; seeds and seedlings are eaten by pests, or infected by pathogenic bacteria, and diseased seedlings and dead seedlings appear. It will reduce the effective number of crops per unit area, resulting in a large area of crop production and quality decline

Abstract
The invention provides a seed treating agent, and belongs to the technical field of pesticides. Active ingredients of the treating agent are thiamethoxam and brevibacterium, particularly 1 gram of preparation contains 2 to 200 billion brevibacterium, and the thiamethoxam accounts for 1 to 40 weight percent of the treating agent. The thiamethoxam and the brevibacterium are synergized with each other, and can provide global protection for seeds by acting on two different target points at the same time. The seed treating agent has good environmental compatibility, low toxicity and biosafety for human, animals, natural enemies and the like, and belongs to a broad-spectrum and high-efficiency biological seed treating agent. A dry-blending agent or suspension seed dressing agent can be prepared by adding proper auxiliary materials into the treating agent, can be prevent and control grub, wireworm, mole cricket and other underground pests in crop fields of corn, wheat, paddy and the like by seed dressing or seed pelleting, can prevent and control aphid at seedling stage, laodelphax striatellus, thrips palmi karny, trialeurodes vaporariorum, leafhopper and other insects with sucking mouth part, and can prevent and control blast, banded sclerotial blight, full rot, rice blast, botrytis, powdery mildew, bacterial wilt and other diseases.
Description
technical field [0001] The invention belongs to the technical field of pesticides, in particular to a seed treatment agent. Background technique [0002] Seeds and seedlings are vulnerable to damage and infection by various underground and above-ground pests and pathogenic bacteria, and are the most vulnerable link in the growth process of crops; seeds and seedlings are eaten by pests, or infected by pathogenic bacteria, and diseased seedlings and dead seedlings appear. It will reduce the effective number of crops per unit area, resulting in a large-scale reduction in yield and quality of crops. [0003] Seed coating technology is currently the most advanced seed health care technology in the world, and has become an important item of seed standardization. In recent years, my country has vigorously advocated and promoted the seed treatment technology, which is mainly to compound insecticides, fungicides, compound fertilizers, trace elements and plant growth regulators to fo...
