Farmers who grow eggplant know that eggplant is prone to root rot during the growth process, especially in the early spring greenhouse. If the eggplant root rot is not controlled in time, it will easily affect the yield of eggplant, and if it is serious, it will lead to the production of eggplant. So what is the cause of eggplant root rot? How to prevent it? First, the cause of the disease Eggplant root rot is a fungus that is infected by Fusarium solani to the roots of eggplant, causing a large area of ​​dead mites. The pathogen generally invades from the wound in the root of the eggplant, and then produces conidia at the affected part, and spreads and spreads by means of rainwater, irrigation water, and the like. Second, the symptoms In the early stage of eggplant root rot, eggplant leaves showed wilting during the day, and sooner or later indicated normal growth. The base of the eggplant seedlings and the epidermis of the primary roots are brown, and the capillary roots are rotted, which causes the supply of nutrients of the eggplant seedlings to be blocked. However, after repeated occurrences of such a situation, the eggplant seedlings eventually turn yellow and die. Third, prevention measures 1. Agricultural control (1) Reasonably determine the mouth and rotation In the practice of sorghum cultivation, the depth of the side ditch and furrow should exceed 40 cm, and the plant line should be no less than 40×40 cm to avoid root rot caused by rainwater in the roots of the eggplant. (2) Applying farmyard manure and applying less fertilizer 100 kg of pig manure can be used, 2 kg of quicklime, 10 kg of firewood fertilizer can be evenly mixed, and fertilized around the root of tomato seedlings according to the standard of 2 kg per plant. It should be noted that before applying farmyard manure, it is necessary to dry it and sterilize it with sunlight. (3) Pay attention to timely drainage and clearing in the rain to prevent root rot caused by excessive moisture in the soil. In case of long-term drought, carbendazim should be sprayed with water to spray the roots of the eggplant seedlings about 3 days before the irrigation. Then, the tomato seedlings should be irrigated with small water on a sunny morning, and then spread with hay ash to the around the eggplant seedlings. The disease resistance of eggplant seedlings reduces the incidence of root rot. 2, chemical control (1) Before planting the tomato seedlings, it can be mixed with 50% carbendazim WP 2 kg and 35 kg of fine soil, and 50 g per plant is used to prevent disease. (2) After the tomato seedlings are planted, if the eggplant seedlings are found to be dead due to root rot, the dead plants should be removed in time, and the plants should be disinfected with quicklime, and the dead plants should be concentrated and burned. (3) In the early stage of root rot disease, it can be treated with 2000 times of copper sulfate or 800 times of benzoic acid WP 800 times, but the dosage should not be too much. Under normal circumstances, each plant is filled with 0.2 liters of liquid, once every 10 days, 2-3 times in a row can cure the root rot of eggplant and prevent its spread. The above is the cause, symptoms and prevention measures of eggplant root rot. Eggplant root rot has a great influence on eggplant. Therefore, farmers must master the above prevention and control measures to prevent and cause unnecessary losses.
