Detailed Explanation of Seed Treatment Methods for Autumn-Sown Wheat
How should autumn-sown wheat seeds be treated? Please help introduce the following methods that can be used to treat wheat seeds before sowing: 1. Insect-control treatment. For underground wheat pests such as mole crickets, white grubs, and wireworms, you can use 0.5 kg of 50% 1605 emulsion, add 50 kg of water, mix with 500 kg of seed, and let it sit sealed for 4-6 hours; or use 75% phox...

Before sowing wheat seeds, you can refer to the following treatment methods:
1. Insect-control treatment. For underground wheat pests such as mole crickets, white grubs, and wireworms, you can use 0.5 kg of 50% 1605 emulsion, add 50 kg of water, mix with 500 kg of seed, and let it sit sealed for 4-6 hours; or use 0.5 kg of 75% phoxim emulsion, add 50-100 kg of water, mix with 500-1000 kg of seed, and pile and seal for more than 4 hours; or use 0.5 kg of 75% 3911 emulsion, add 15-25 kg of water, mix with 150-250 kg of seed, and seal for 12-24 hours for control. At the same time, it can also kill aphids and small brown planthoppers, and simultaneously control yellow dwarf disease and.
2. Disease-control treatment. For wheat root rot, at sowing time you can use 0.3% captan, tuijunya, or fu-mei-arsenic based on seed weight, or 0.15% carbendazim or carboxin for seed dressing, which can not only significantly reduce the disease incidence but also promote seed and seedling protection; for wheat scab, soak the seed with 1% quicklime water, with the water covering the seeds by 9.9-13.2 cm, soaking for 3-4 days at a temperature of 20°C, 2 days at 25°C, and one day at 30°C. After putting the seeds into the lime water, stirring is prohibited to prevent reducing the sterilization effect. For wheat bunt, use 0.3% hexachlorobenzene based on seed weight, or 0.3% phytonquinone, or 0.2% quintozene, or 0.3% thiram for seed dressing.
3. Drought-resistance treatment. Add 3 kg of crushed superphosphate to 50 kg of clean water, stir thoroughly with a wooden stick, then let it stand, pour the clarified liquid into another container to obtain a 6% superphosphate extract, then add 50 g of boric acid and stir evenly to obtain a phosphorus-boron mixed solution. Spray the phosphorus-boron mixed solution at 10% of the air-dried seed weight, turning the seeds while spraying, requiring every seed to be evenly soaked in the solution. After treating the seeds with this method, the plant's water absorption and water retention capacity are enhanced, which helps protect the protoplasm in the plant and shows a drought-tolerant effect.
4. Plant growth regulator treatment. For seed soaking with Fuleiding, take 1 mL of the stock solution per kilogram of wheat seed, add 2 kg of water to dilute and mix evenly, submerge the seeds for 8-24 hours, then take out the seeds and dry them in the shade for sowing. Soaking seeds by this method can enhance drought resistance, cold resistance, and disease resistance, and strengthen wheat growth vigor and vitality.
5. Trace element fertilizer treatment. Wheat is not sensitive to zinc, but applying it significantly increases yield. For seed dressing, use 5-6 g of zinc sulfate per kilogram of seed. Weigh the zinc sulfate, dissolve it in a small amount of water, spray it onto the wheat seeds, stirring while spraying, and mix the wheat seeds evenly with small amounts added multiple times.
