In April, the following pests and diseases should be prevented in wheat planting:
Wheat take-all: from the greening stage to before jointing, use 100 g of 20% triadimefon EC per mu, or 150 g of 15% triadimefon wettable powder, mix with 50-70 kg of water, and use a sprayer with the swirl plate removed to spray the wheat roots along the rows. The effect is very obvious, and it can also control wheat sharp eyespot.
Wheat root rot: at the early stage of onset, use 20-30 g of 12.5% hexaconazole or 40-50 g of 20% triadimefon, mix with 50-60 kg of water, remove the nozzle and spray directly at the base of the wheat stems, once every 15 days, for two consecutive sprays. Alternatively, use 50 ml of 50% strong fungicide and 5 ml of Jiamu, add 40 kg of water, and spray once every 7-10 days for 2-3 consecutive sprays.
Wheat sharp eyespot: at the early jointing stage of wheat, use 100-150 ml of 5% jinggangmycin aqueous solution per mu, mix with 50-70 kg of water, and spray the base of the wheat stems along the rows.
Wheat powdery mildew and rust: use 50 g of 20% triadimefon EC per mu, mix with 60-70 kg of water, and spray at the initial stage of onset.
Wheat aphids: use 10 g of 10% imidacloprid or 3% acetamiprid wettable powder per mu, mix with 50-60 kg of water, and spray to kill.
Wheat red spiders: use 15 ml of 2% abamectin per mu, mix with 30-40 kg of water, and spray, which also controls small brown planthoppers and prevents wheat dwarf virus disease.
Soil-dwelling pests: after wheat turns green, soil-dwelling pests begin to move upward and cause damage. When the rate of damaged wheat seedlings reaches 3%, use 2-2.5 kg of 3% phoxim granules per mu mixed with 50 kg of fine soil, spread along the rows, and then hoe. Alternatively, use 20-30 ml of 50% phoxim EC, mix with 300-500 ml of water, mix with 1-1.5 kg of roasted corn grits, soybean cake or wheat bran, and scatter it into the wheat field in the evening to trap and kill.
