What's the use of wheat seed coating? Please introduce that seed coating and chemical seed dressing before wheat sowing is a key measure to lower the base number of diseases and insect pests, move forward the control gate, and reduce the occurrence of diseases and insect pests in the coming year. Seed coating can effectively prevent and control wheat rust, powdery mildew, sheath blight, smut, total erosion disease, virus disease, underground pests, wheat aphid, gray planthopper and other diseases and insect pests. Pesticide seed dressing technology insecticides: in the general occurrence area of underground pests, the seeds are mixed with 40% phoxim according to 0.2% seed quantity, or 48% chlorpyrifos EC according to 0.3% seed weight for 4-6 hours, which can effectively control mole cricket, grub, golden needle insects and other underground pests, as well as red spiders, aphids and gray planthoppers at seedling stage. Fungicides: wheat fishy smut, scattered smut, root rot, sheath blight, total erosion and other occurrence areas, you can choose 2% tebuconazole (Likexiu) dry mixing agent or wet mixing agent 10-15 grams of mixed wheat seed 10kg, or 2.5% chlorobenzene suspension 10-20ml mixed wheat seed 10kg, or 40% pentachloronitrobenzene at 0.4% 0.5% of the seed amount. Growth agent: you can choose dryland dragon seed quantity 0.5%, or 0.2% Murray 0.3% potassium dihydrogen phosphate, etc., to improve the emergence rate, accelerate the emergence of wheat seedlings, enhance their own disease resistance, and reduce the chance of bacterial infection. Note: the dosage of seed dressing must be carried out in strict accordance with the requirements. Generally, the insecticide should be diluted into a liquid by adding water according to the required proportion, and the liquid should be evenly sprayed on the seeds with a sprayer, then spread out for 4-6 hours to dry, then mix fungicides and regulators before sowing, and sow along with mixing, not for a long time. In addition, special personnel should be responsible for seed dressing, which should be carried out in strict accordance with operating standards. It is forbidden to smoke, drink water and eat snacks during medicine mixing. Wash hands and wash face in time after medicine mixing. Wheat seeds mixed with medicine should be stored separately. Human and animal poisoning accidents are strictly prohibited. Seed coating technology has the advantages of simple, slow release and long-term effect. it not only can control diseases and insect pests, but also has the function of seed fertilizer. Each district and county can select the seed coating agent with appropriate formula according to the occurrence types of diseases and insect pests. For example, to control wheat sheath blight, root rot, fishy smut and other diseases, you can choose 25 g / L fipronil suspension seed coating agent, 0.5-1 kg per 10 ml of water, 10 kg mixed wheat seed, or 30 g / liter difenoconazole suspension seed coating agent according to the seed amount of 0.2% color 0.3%, or 15% multi-Fu seed coating agent 1: 60-80 (drug ratio). For example, to prevent diseases such as aphids, underground pests and rust, you can choose 60% imidacloprid suspension seed coating agent (Gao Qiao) 30 ml 6% tebuconazole suspension seed coating agent (Likexiu) 10 ml, add water 0.3-0.4 kg, coating 15-20 kg. Note: seed coating should be done as early as possible to ensure that the efficacy is fully absorbed by the seed.
