What pesticide is used to coat wheat seeds? What is the purpose of wheat seed coating? Please give an introductionCarrying out seed coating and chemical seed dressing before wheat sowing is a key measure for reducing the pest and disease base, moving the control threshold forward, and lessening the occurrence and damage of pests and diseases in the coming year. Zhongdiwang has compiled the common coating agents and precautions for wheat seeds, listed below for netizens' reference.
Common insecticides for wheat seed coating:
In areas where soil-dwelling pests generally occur, dress seeds with 40% phoxim at 0.2% of the seed amount, or with 48% chlorpyrifos emulsifiable concentrate at 0.3% of the seed weight; after dressing, pile and cover for 4-6 hours. This can effectively control soil-dwelling pests such as mole crickets, white grubs and wireworms, and also control red spiders, aphids and small brown planthoppers at the seedling stage.
Common fungicides for wheat seed coating:
In areas where wheat bunt, loose smut, root rot, sheath blight and take-all occur, you may choose 2% tebuconazole (Raxil) dry dressing or wet dressing at 10-15 grams to dress 10 kg of wheat seed, or 2.5% fludioxonil (Celest) suspension concentrate at 10-20 milliliters to dress 10 kg of wheat seed, or 40% quintozene at 0.4%-0.5% of the seed amount for seed dressing.
Common growth agents for wheat seed coating:
You may choose Handilong at 0.5% of the seed amount, or 0.2%-0.3% potassium dihydrogen phosphate, etc. for seed dressing, to increase the emergence rate, promote faster emergence of wheat seedlings, enhance their own disease resistance, and reduce the chance of pathogen infection.
Coating formulas for wheat control of sheath blight, root rot and bunt:
You may use 25 g/L fludioxonil suspension concentrate seed coating agent, dilute 10 milliliters in 0.5-1 kg of water, and dress 10 kg of wheat seed; or 30 g/L difenoconazole suspension concentrate seed coating agent at 0.2%-0.3% of the seed amount for seed dressing, or 15% carbendazim·thiram seed coating agent at 1 to 60-80 (agent-to-seed ratio) for seed dressing.
Coating formulas for wheat control of aphids, soil-dwelling pests and rust:
You may choose 60% imidacloprid suspension concentrate seed coating agent (Gaucho) 30 milliliters + 6% tebuconazole suspension concentrate seed coating agent (Raxil) 10 milliliters, add 0.3-0.4 kg of water, and coat 15-20 kg. Note: seed coating should be done as early as possible to ensure the pesticide effect is fully absorbed by the seeds.
Precautions for wheat seed coating:
The amount of seed dressing agent must strictly follow the requirements. Generally, first dilute the insecticide with water in the required proportion to make a medicinal solution, use a sprayer to evenly spray the solution onto the seeds, pile and cover for 4-6 hours, then spread out to dry, and before sowing mix in the fungicide and regulator; mix and sow immediately, and do not leave it standing for long. In addition, seed dressing with chemicals must have a dedicated person in charge and be carried out strictly according to operating standards. During seed dressing, smoking, drinking water and eating snacks are prohibited; after seed dressing, wash hands and face promptly, and store chemically dressed wheat seed separately, and strictly prohibit poisoning accidents to people and livestock.
