Select pest-resistant varieties to select pest-resistant varieties for the main pests and diseases in the local area, and do a good job of rational distribution of varieties.
Create disease-preserving ecological environment, fine-tune the land, remove the diseased debris and weeds in the field. Rational rotation, formula fertilization, application of decomposed farmyard manure. Adopting suitable cultivation techniques such as late sowing, semi-precision sowing, etc., to improve the resistance of the wheat itself to pests and diseases.
Treatment of soil underground pests and wheat midgein re-emergence areas, 50-% phoxim or 40% methyl iso-phosphorus emulsifiable concentrate 0.25-0.3 kg per acre, adding 1-2 kg of water, 25 kg of fine soil to make toxic soil. It can also be used with 3% methyl isoflavone or phoxim granules 2.5-3 kg, fine soil 15-20 kg, evenly spread the ground before plowing the ground, and turn into the soil with the plow.
For the common pests of underground pests, 50% methyl isoflavin or 50% phoxim emulsifiable concentrate 50g, 4-5 kg ​​of water, 40-50 kg of wheat. Wheat sheath blight, smut, stripe rust, can be used 2% Likexiu according to the weight of 0.1% -0.15%, or 20% triadimefon EC by weight of 0.15%, or 12.5% ​​Heguoli according to the weight of 0.12% Dosage seed dressing. Excessive use of triadimefon and hepatic fruit has an effect on wheat emergence and growth, and the dosage should be strictly controlled to avoid phytotoxicity. For wheat total eclipse, use 200 ml of 2.5% cola, add 1.5-2 kg of water, mix 50-100 kg of wheat, and dry it for sowing. Wheat yellow dwarf disease, bush dwarf disease, use 75-5% phorate emulsifiable concentrate 100-150 ml, add water 3-4 kg, mix 50 kg of wheat seeds, mix well and stack for 12 hours. In the mixed areas of pests and diseases, it is necessary to vigorously promote the mixing of seedicides and insecticides, and mix the insecticides with fungicides to prevent poisoning of humans and animals. Seed coating seed coating agent is a new type of pesticide which is processed by compounding insecticide, fungicide, micro-fertilizer, plant growth regulator and film-forming agent. The seed coating has the advantages of simple, slow release and long-acting effect. In addition to controlling pests and diseases, it also has the role of seed fertilizer. Appropriately formulated seed coating agents can be selected according to the type of pests and diseases.
The sowing period of winter wheat is a key period for controlling various pests and diseases of wheat. This period of prevention and control saves labor, saves time and medicine, can control a variety of pests and diseases, and has a multiplier effect. In the wheat planting period, the following control measures are recommended:
