Key Technical Points for Pest and Disease Control During the Autumn Sowing Period of Wheat

The autumn sowing period is the foundation and key to doing a good job of wheat pest and disease control. We hope farmers will seize this favorable opportunity of autumn sowing, adopt effective measures, and carry out pest and disease control work well for soil-dwelling pests, wheat powdery mildew, and other problems, striving to eliminate wheat pests, diseases, and weeds in the bud stage.

The technical measures for wheat pest and disease control during the autumn sowing period are as follows:

Do a good job of plant quarantine. During the autumn sowing period, seeds are transported frequently, making it easiest to spread quarantine pests and diseases. Therefore, quarantine work must be strengthened to strictly prevent quarantine pests, diseases, and weeds from spreading and proliferating along with seed transport. When buying seeds, be sure to purchase seeds with a quarantine certificate from a legitimate seed business entity.

Strengthen agricultural control. Main technical measures include reasonable crop rotation, deep plowing to improve the soil, fine land preparation, soil testing and formulated fertilization, reasonable fertilization, not applying uncured organic fertilizer, sowing at the appropriate time and rate, and clearing volunteer wheat seedlings and weeds from fields, field edges, and yards.

Soil pesticide treatment. For plots with severe soil-dwelling pest occurrence in the previous crop, when preparing the land before sowing, mix the pesticide with dry fine soil, mix evenly, and spread it uniformly on the soil surface. After spreading, immediately shallow plow or harrow, or mix the pesticide with fertilizer and apply it.

Implement pesticide seed dressing. Seed coating and pesticide seed dressing are economical, simple, safe, and efficient measures for pest and disease control throughout the entire wheat production process, and are also basic key measures for wheat pest and disease control. Their application should be strongly promoted.
