Pay attention to the control of diseases and insect pests during wheat sowing

At present, the sowing season of wheat has come. In recent years, underground wheat pests (mole cricket, golden needle worm), locust, cricket, wheat smut, wheat clump dwarf disease, wheat sheath blight, root rot, leaf blight and wheat total erosion disease have occurred in varying degrees in our county, and some plots have occurred seriously. In order to ensure that the whole wheat seedlings are strong, and in order to ensure a bumper harvest next year, comprehensive measures should be taken to control the wheat sowing period.

Prevention and control measures:

First, seed selection: select disease-free and insect-free seeds, especially those without smut.

Second, do a good job in weeding and eliminating wasteland, and remove weeds in the fields.

Third, sowing seeds at the right time. The suitable sowing date in our county is October 1-8, and appropriate late sowing can reduce the occurrence of cluster dwarf disease.

4. Seed treatment:

1. Use 40% Lesbon EC and 40% phoxim EC to mix wheat seeds 400-500 kg, add appropriate amount of water, and sow seeds for 4 hours, which can effectively control underground pests and control locusts, planthoppers, crickets and so on.

2. Wheat smut, sheath blight and rust can be controlled by sowing wheat seeds with 50 kg of 100 grams of 15% trimethoprim 80-100 g, 12.5% uniconazole 20-30 g and 70% methyl topiramate for 2-4 hours.

3. After mixing 20ml of 20ml + water 100ml to 150ml, evenly mix seeds 10kg or coat seeds to control wheat total erosion disease; or 12.5% total erosion water suspension 20-40ml, mixed with water 150g and wheat seeds 10kg per mu, and the dosage can be adjusted according to the degree of the disease.

Fifth, spray control: in the wheat seedling to three-leaf stage, 25% Kuaishaling EC 1000 times spray can control planthopper, soil locust, cricket, pay special attention to field edge, ditch edge, interplanting wheat drug control.
