Wheat root disease is a problem often encountered by friends who grow wheat in recent years. Due to the adjustment of planting structure and the increase of chemical fertilizer application rate, the occurrence of wheat root disease has also increased year by year. How to prevent and cure wheat root disease? Let me introduce the prevention and control of wheat root disease.

Wheat root disease is mainly caused by the following pathogens: Rhizoctonia solani, wheat total rot, and wheat root rot, and the corresponding root diseases are wheat sheath blight, wheat total etch, and wheat root rot.

Causes of wheat root disease:

1. Heavy cropping: Wheat is planted year after year, and the amount of bacteria in the soil increases year by year, resulting in an increase in the incidence of root diseases.

2. Variety is resistant to disease: Large-scale planting of susceptible varieties provides good parasitic conditions for disease infiltration, reproduction, accumulation and spread.

3. Fertilization is unreasonable: farmers apply heavy nitrogen fertilizer, lightly apply phosphorus and potassium fertilizer, organic fertilizer, reduce soil organic matter content, deteriorate soil structure, wheat plants are not robust, and poor resistance to stress.

4. Improper management: In production, planting management is extensive, plant density is high, ventilation and light transmission are poor, irrigated land, low water holding capacity is high, and drainage is poor.

5, improper control: wheat seed dressing only use insecticides, not fungicides.

Wheat root disease prevention and control measures:

1. Selection of resistant varieties: Eliminate susceptible varieties, select resistant varieties and comparatively resistant varieties according to local conditions.

2. Reasonable fertilization: Before planting wheat, apply more soil and fertilizer, increase soil organic matter, increase phosphorus and potassium fertilizer, and apply proper amount of nitrogen fertilizer according to ground force.

3, the rotation of the collapse: reasonable rotation of the collapse, adjust the planting structure, using scientific planting methods.

4, pesticide dressing: wheat before sowing with 20% powder rusting cream 50 ml or 10% powder rusting wettable powder 150 grams of water 2-3 kg, seeded 50 kg.
