Control of Root Rot of growing Soybean

1. Disease-resistant varieties were selected.

2. Rotation with corn, millet, sweet potato and other non-host crops.

3. Increase the application of farm manure, potash fertilizer, phosphate fertilizer and so on when sowing.

4. When sowing, metalaxyl granule was applied to make the soybean root absorb and prevent the root infection.

5. Mix seeds with 35% metalaxyl powder with 0.3% seed weight before sowing.

6. Strengthen field management, cultivate soil and weed in deep and middle ploughing in time, and remove stagnant water in time after rain to prevent excessive humidity.

7. when diseased plants are found, the remnants of diseased plants are removed thoroughly, and quicklime is disinfected in and around the planting holes of diseased plants.

8. After the occurrence of the disease, it is difficult to cure and prevention should be given priority to. For prevention, you can choose 40% Gen Fuling 400x solution, or 70% methyl thiophanate wettable powder 1000 times solution, or 58% Ruidu wettable powder 600x solution, or 50% carbendazim wettable powder 400x solution, or 75% chlorothalonil wettable powder 600x solution, or 77% chlorothalonil wettable powder 600x solution, or 64% trichlorothalonil wettable powder solution 900x. Any of the above pesticides was sprayed with 600x liquid fertilizer, 500x fulvic acid solution and 1000 times rooting powder solution. Spray once every 7 days, 2-3 times continuously, using alternately, focusing on the base of the main stem of the plant. If the above solution is used to irrigate the root of the plant, the effect is better.
