First, the characteristics.
Peanut root rot can occur in every growth period of peanuts. Peanut disease after sowing before sowing can cause bad seeds and rotten buds; damage caused by seedling stage leads to root rot and seedling blight; damage caused by adult plants causes root rot, stem rot and rot, and the upper part of the diseased plant has short stature and poor growth. The leaves turned yellow and eventually the whole plant withered. Since the disease is mainly located in the roots and vascular bundles, the roots of the diseased plants turn brown and rot, the vascular bundles turn brown, and the main roots shrink and dry rot, resembling mouse tails, and the surface of the affected area has a yellow-white to reddish mildew layer.
Second, control methods
1. Turn off the good seeds. Do a good job in seed collection, selection, drying, and storage: sow seeds before sowing, remove seeds that are discolored, mildewed, and damaged, and use a 40% triadimefon or carbendazim wettable powder with a seed weight of 0.3%. Species, sowed after 24 hours of sealing.
2. Reasonably apply base fertilizer. Base fertilizer should be re-applied phosphorus and potash fertilizer, appropriate use of nitrogen fertilizer, 30-40 kg of potassium chloride compound fertilizer per mu, 30 kg of soil conditioner, 5-10 kg of microbial agent or 200 g/mu of soil conditioner and compound fertilizer Use it.
3. Drug control. The bacteria can be used to collect roots or spray at the stem base. Potassium permanganate 600-1000 times can also be used to spray the roots of 3-4 sprays per mu.
4 Rational rotation. Peanuts and cereal crops, sweet potatoes, or cotton and vegetables have their own crop rotation. Due to the different characteristics of fertilizer requirements, they can make fuller use of nutrients in the soil. It can also reduce the occurrence of diseases.
