How to prevent and control soybean root rot? These methods you need to master

1. Select disease-resistant varieties.

2. Rotate with non-host crops such as corn, millet, and sweet potato.

3. When sowing, apply more farmyard manure, potassium fertilizer, phosphate fertilizer, etc.

4. When sowing, apply metalaxyl granules so that soybean roots can absorb them to prevent root infection.

5. Before sowing, treat seeds with 35% metalaxyl powder at 0.3% of seed weight.

6. Strengthen field management, carry out timely deep plowing and intertillage hilling and weeding, and drain accumulated water promptly after rain to prevent excessive humidity.

7. When diseased plants are found, pull them out promptly, thoroughly remove the diseased plant residues, and spread quicklime in the planting holes of diseased plants and around them for disinfection.

8. Once this disease occurs, it is very difficult to cure, so prevention should be the main approach. For prevention, you may choose 40% Genfuling 400-fold solution, or 70% thiophanate-methyl wettable powder 1000-fold solution, or 58% metalaxyl wettable powder 600-fold solution, or 50% carbendazim wettable powder 400-fold solution, or 75% chlorothalonil wettable powder 600-fold solution, or 77% Keshade wettable powder 600-fold solution, or 64% Sandofan wettable powder 900-fold solution. Any one of the above pesticides plus amino acid (such as soybean Jianlibao or Santianlv, etc.) liquid fertilizer 600-fold solution, plus fulvic acid salt 500-fold solution, plus rooting powder 1000-fold solution for spraying. Spray once every 7 days, 2-3 times in succession, using them alternately, focusing on spraying the base of the main stem of the plants. If the above medicinal solution is used to drench the roots of the plants, the effect is even better.
