I. the cause of wheat root rot

1. Weather reason

There are many reasons for the weather, such as the common rainy and low temperature, in which case, the resistance of wheat itself is weak, and the incidence of root rot is much higher.

two。 Field management

In soil preparation and sowing time management is not in place, such as sowing too late or too early, sowing too deep or too shallow, and poor quality of field preparation, wheat grown in these cases is easy to be infected with root rot.

3. Continuous cropping for many years

Due to some reasons, wheat roots are easily infected with root rot when they are cut or broken. Under the same circumstances, intact wheat roots are more resistant to the disease.

2. Distribution range of wheat root rot.

There is a high incidence of wheat root rot in Northeast, Northwest, North China and Inner Mongolia, and the disease can also infect Gramineae crops such as barley, oats, rye and more than 30 species of Gramineae weeds. Therefore, we must do a good job in prevention and treatment to avoid losses caused by the outbreak of the disease in a large area.
