How to Control Wheat Root Rot by Root Rot and Stem wilt Leaf Yellow

The symptom of wheat root rot is similar to that of retting root disease. After the wheat root was infected by bacteria, it first spread from the fibrous root to the branch root and then to the main root, and the color became dark brown. After the disease, the roots slowly rot, the initial ground stem has no obvious symptoms, but for a long time, there is no fertilizer and water supplied by the roots, the stems will wither and the branches and leaves will turn yellow until death.

Wheat root rot

1. Causes of wheat root rot:

Wheat continuous cropping for many years, soil organic matter is too small, coupled with unfavorable weather; or planting wheat soil is too high, both sides of the trench fertilization or weeding, damage the root system; or because Rain Water, irrigation, too much water, drainage is not timely; or lack of light, low temperature and high humidity, soil viscosity is too large, soil caking, poor ventilation; when the root system is injured and broken, it is easy to be invaded by germs. Rain Water has a lot of seasons.

Second, control the root rot of wheat:

1. Agricultural prevention and control methods:

A, because stagnant water and untimely drainage will cause the disease, so choose a relatively flat place to plant. B, do a good job of drainage, discharge stagnant water, especially in the rainy season. C, ploughing in time to increase soil permeability. D, apply rotten organic fertilizer, potash fertilizer, phosphate fertilizer to make wheat "strong" to enhance disease resistance.

2. Pesticide control:

① seeds were sterilized. Disinfection dosage of wheat seeds: seeds can be mixed with 600,800 times of chlorpromazine or 1000 times of carbendazim. Before planting ②, the soil was disinfected. You can use 1200-1500 times of carbendazim or 1500-2000 times of carbendazim. Root irrigation was performed after the onset of ③. 1200-1500 times of carbendazim or 1500-2000 times of carbendazim.
