Symptoms Eggplant verticillium is commonly known as "half-side yellow, half-mad". It begins to show symptoms after fruit setting, and it develops from bottom to top or from side to whole. At first, the leaves turn green and yellow between the veins and the leaf margins, and then develop to the half leaves or the whole leaves turn yellow. In the early stage of the disease, the diseased leaves are wilting in the sunny days, and can be restored in the morning and evening. The diseased leaves turn yellow from yellow in the late stage, eventually leading to dryness and shedding. In severe cases, the whole plant leaves become brown and only the stems remain, until the whole plant is dead. The disease is a whole-plant disease. The typical symptoms are dead type, macular type, yellow mottled type. The roots, stems, branches and petioles of the diseased roots are browned, and the squeezed section has no milky white concentrated liquid. Unlike the bacterial wilt.
Prevention (1) Selection of resistant varieties. Choose early-ripening and low-temperature resistant varieties, such as Jizao Changzhi No.1, Korean Black Dragon King Long Eggplant, Japanese New Black Coral Eggplant, etc. (2) Seed treatment. Warm the water before sowing, soak it in hot water at 55 °C for 10-15 minutes, then germination. (3) Rotation. It has been rotated for more than 4 years with non-solanaceae crops such as onions and garlic. (4) Reasonable close planting. It is advisable to plant 1800-2000 plants per 667 square meters (1 mu). (5) Balanced fertilization. Generally, 667 square meters of fully-fertilized high-quality soil mixed fertilizer 3000-4000 kg, phosphorus and potassium fertilizers in the seedling stage, and the application of nitrogen fertilizer and potassium fertilizer. After the vine is harvested, 1000-1500 times of Fuwan potassium solution and 1500-2000 times of bryostatin 481 and other foliar fertilizers are sprayed every 5-7 days to enhance the plant's resistance. (6) Scientific watering. Do small water and water pouring, keep dry and see wet, avoid flooding, protect micro-drip and dark-cast under the membrane. (7) Grafting and disease prevention. Common rootstocks include red cigar, torubum, and warm shed anvil. (8) Chemical control. The planting period, the initial flowering period and the saplings were harvested with 28% activated ion 500-600 times solution, 0.5 kg per plant; 70% diclofenac 500-600 times solution or tomato disease in the early stage of the disease Tylenol 500-600 times liquid, or 10% treatment of wilt water agent 200-300 times liquid, or Zhikang 600-800 times liquid irrigation root, each plant 150-200 ml, 7-10 days once, continuous 2 - 3 times.
