Watermelon virus disease, commonly known as lobular disease, is one of the main diseases of watermelon. There is no specific medicine for this disease, and prevention is the key. 1. Control the mites to remove weeds in and around the melon fields, and cut off the breeding ground for mites. At the beginning of the seedling stage, every 2 to 10 days, the medicinal agent 2.5% cyhalothrin 1500 times solution or 10% imidacloprid 1500 times solution and 20% virus A600 times mixed solution are sprayed to prevent the fruiting period. Before and after the wheat harvest, if there are locusts flying, immediately apply quick-acting insecticides, such as 20% fenpropathrin emulsifiable concentrate 3000~4000 times liquid or 3% acetamiprid emulsifiable concentrate 1500~2000 times liquid. At the same time, we must control the crops and weeds near the melon field to prevent the poisonous aphids from transmitting poison in the field. Because the locusts are far away from the distance, the variety is large, and the breeding is fast, it is best to carry out unified drug application and prevention, in order to get twice the result with half the effort. 2. Strengthen field management, pay attention to drought prevention, timely watering in appropriate amount, and spray 0.1% zinc sulfate and multi-micro fertilizer on the foliage to improve plant resistance. When the field is smashed and pruned, the robust plants are first sorted out, and the seriously ill plants found in the field should be removed in time to cut off the source of the virus. 3. In the early stage of the disease prevention or treatment, the plant is lighter, using 20% ​​virus A wettable powder 500 times liquid or 1.5% phytotoxic milk 1000 times liquid, 5% bactericidal water clearing agent 200~400 times liquid, 0.5% anti-drug Spray No. 1 water agent 300 times liquid, 6% triazole nucleoside · copper · zinc 500 ~ 800 times liquid for spray control. Spray once every 7~10 days, even spray 2~3 times.
