Tomato damping-off mostly occurs in seedling stage, seeds are easy to suffer before they are unearthed, and there are often rotten seeds, dead seedlings, damping-off and other symptoms. Control methods are as follows: 1, seedbed sterilization, choose a slightly higher place to hang, convenient drainage. 2. Strengthen the management of seedling stage, and the planting density should not be too large. Pesticide fungicide control methods: Prevention programmes: The root was irrigated with 500 times solution of Qingkuliki at the seedling stage and the first panicle flowering and expansion stage, once every 7 days, 2-3 times in each stage. Treatment options: 50ml of Qingkulike +10m of garlic oil mixed with 15kg of water are used for irrigating roots in small areas of seriously diseased plants and plants within 2-3 meters around the diseased plants for two times at an interval of one day, and then consolidating the medicine for one time at an interval of 3-5 days after the second medicine according to the disease condition; and the rest can be prevented by acupoint irrigation with 500-fold solution for 1-2 times at an interval of 3-5 days. 1. When irrigating, the amount of water per plant should be irrigated thoroughly (about 100-200ml at seedling stage; 200-500ml at flowering and fruiting stage, depending on plant growth period and soil humidity). 2. When the disease is serious and the growth of the plant is weak, it can be applied with 300 times solution of "Seaweed Rooting Agent-Foundation Treasure" at the same time, and root irrigation can be carried out at the same time to promote root growth. Notes: When the plant is weak, foliar fertilizer (Wofengsu, Duodasu) needs to be sprayed to strengthen the plant and enhance the disease resistance of the plant.
