When Wheat Leaf Rust Controls

In most wheat areas of China, the wheat rust bacterium after harvest is transferred from the wheat seedlings to the self-producing wheat seedlings over the summer. After the wheat is sown, the pathogens are transferred to the wheat seedlings for harm and wintering. After turning green, the germs invade new leaves when the average temperature is stable above 10°C. Climatic conditions are the determinants of the popularity of leaf rust in spring. The temperature rose early and there was rain dew. Leaf rust disease developed early and the disease was heavy. Prevention and treatment of wheat leaf rust can be controlled when the diseased leaf rate reaches 5% to 10%. In recent years, wheat leaf rust has only occurred in some areas of our province and has not occurred to a certain extent. In areas where leaf rust occurs, it is generally not necessary to use individual drugs for prevention and control. It can be combined with the control of sheath blight, powdery mildew, and other diseases.
