The soil chemical treatment is applied to the plots where the underground pests are heavier. Before the sowing, the soil is mixed with fine soil, mixed and evenly spread on the soil surface. Immediately after sowing, shallow tillage or alfalfa, pesticides and fertilizers can also be applied. Mixed application.
The implementation of pesticide seed dressing and chemical dressing is an economic, simple, safe and efficient measure to control pests and diseases throughout the wheat production process.
