Eggplant verticillium wilt, also known as half mad, black heart disease, known as plant cancer. In recent years, the occurrence of this disease has been increasing year by year. The incidence rate in general years is 40% to 50%, and in severe years, the incidence rate is as high as 70% or more. Symptoms of Verticillium wilt occur mostly after fruiting in the pod, and gradually increase after entering the full fruit period. In the early stage of disease, the veins or leaves of the middle and lower leaves of the plant yellowed and withered and curled upwards, gradually developed to half of the branches and leaves turned yellow and died, and the fruit rigidity was not long. When the disease is serious, the whole plant withers away, the leaves fall off and become light stalks, and the vascular bundle becomes brown as the rhizome is cut open. Incidence conditions 1. Climate: Verticillium wilt occurs the most when the weather is humid and rainy and temperatures reach 20°C to 25°C. From the time of planting to the flowering stage, the more days the average daily temperature is below 15°C, the sooner and later the occurrence of Verticillium wilt. When the temperature exceeds 28°C, the occurrence of verticillium wilt is inhibited. 2. Cultivation: Verticillium wilt occurs more severely in plots with low-lying terrain, poor drainage, heavy soil viscosity, and frequent re-harrowing. At the time of cultivation, if the root system is damaged during planting, the density is too thin, and unfamiliar human and animal manure is applied, etc., it is easy to cause a disease pandemic. Control Technology 1. In advance prevention, 5 to 6 bags of Enbibacterial powder are used per acre before planting, and 100 kg of water is poured into the soil with each bag of bacteria powder to promote rooting and enhance disease resistance. 2. Chemical control: At the beginning of the disease, use 1 capsule of Chunyu No. 1 and a sterile and highly effective fungicide, add 15-30 kg of water and spray, spray once every 7-10 days, spray 2 or 3 times, and the control effect can be achieved. More than 98%.
