Peanut root rot is commonly known as "rat tail" and rot. Each growth period can be onset. Infected just germinated seeds, causing bad species: seedlings were injured, the main root became brown, and the plants withered. In adult plants, the main root rhizomes were sulky and brownish-spotted. The roots were wet and rot. The cortex was brownish and rot, easily detached and detached. There were no lateral roots or very few, and they resembled rat tails. Roots of adventitious roots when wet. The upper part of the diseased plant is short, poorly growing, the leaves turn yellow, and the flowering results are few and mostly fruiting. Recently, due to frequent rain, moisture in the ground, poor soil permeability, rooting, and root rot caused the roots to absorb nutrients and cause the leaves to yellow. If left untreated, the yield will be greatly affected. Control measures: 1. Increase fertilizer and improve soil. Pay attention to the use of the net feces without diseased body, appropriate application of phosphorus and potassium fertilizers. In the early management of peanuts, plant growth regulators should be sprayed in time to suppress the growth and promote the differentiation of flower buds. In the early flowering stage, young fruit stage and fruit expansion stage, the root swelling agent is sprayed to make the underground fruit nutrient transportation conduit thicker. , To increase the vitality of fruit, increase the output of peanuts. 2. Special effects fungicides + foliar fertilizers should be mixed to spray the roots or stem bases. Can be used in combination with peanut leaf spot, peanut scab, 30% propiconazole, difenoconazole (Ai Miao), 20 ml or 50% of Chlorobromo isocyanuric acid, 40 g or 60% of Pyraclostrobin. Water dispersible granules (Baitai) 16g + foliar fertilizer 50ml water 30 ~ 50kg spray, every 10 to 15 days spray 1, even spray 2 to 3 times, alternate application, spray feet thoroughly. If locusts and bollworms occur in the field, 10% imidacloprid 20-25 g, 4.5% beta-cypermethrin 1500 times, or 1.8% abamectin 3,000 times can be added at the same time.
