1. How to treat the disease of white melon

1. Downy mildew

Chemical control: commonly used agents and concentrations of 25% Ruiduo wettable powder or 25% metalaxyl wettable powder, 40% aluminum ethyl phosphorus wettable powder, 78% ethyl phosphorus manganese zinc wettable powder, 68% methyl cream manganese zinc wettable powder, or 50% thiram wettable powder or Bordeaux solution 1 ∶ 1 ∶ 200 times. It should be noted that some varieties are prone to drug damage at seedling stage. Spray 60-70kg per 667m2, once every 7-10 days. If downy mildew is mixed with powdery mildew, it can be sprayed with 1500 times of metalaxyl and 1500 times of metalaxyl; if downy mildew and bacterial leaf spot are mixed, spray 50% copper succinate wettable powder and 25% metalaxyl wettable powder. Mixed dispensing should be used now.

2. Powdery mildew

Chemical control: choose 1000-1500 times of the wettable powder or 1500-2000 times of the EC, spray once every 15-20 days, the control effect is remarkable. Or use 50% sulfur suspension 200,300x solution, 100x solution with 30% dichloromethone or 1000 times solution with 50% methyl topiramate wettable powder, 1000 times liquid of polyparathion, spray about 60kg every 667m2.

3. Anthrax

Drug control: spraying at the initial stage of the disease, commonly used agents are: 65% mancozeb wettable powder, 70% mancozeb wettable powder, 50% carbendazim wettable powder, 50% methyl topiramate wettable powder, 80% anthrax Fumei wettable powder, 20% antibiotic agricultural resistance 120200 times. Spray once every 7-10 days, 2-3 times in a row, and it is better to add micro-fertilizer or foliar fertilizer when spraying. Melons stored or transported in long distance must be strictly selected to get rid of sick and injured fruits. When there are conditions, the use of low-temperature storage and transportation or smear antistaling agent, the temperature is best controlled at about 4 ℃. Too high or too low temperature can easily cause fruit rot.

4. Fusarium wilt

Chemical control: the soil can be applied at the acupoint, and the ratio of soil to medicine is 1 ∶ 100. cover the bottom of the hole, and then cover the soil. The medicament can choose 25% benzoate, 50% carbendazim, 50% methyl topiramate, 40% seed double powder, 0.5-1g per 667m2. (2) root irrigation at the initial stage of the disease. When sporadic diseased plants are found in the field, 500-1000 times solution of benzoate, methyl topiramate, carbendazim or dimethazone can be irrigated around the root of the plant. Each plant is 200-250ml, the interval is 7-10 days, and continuous irrigation is 2-3 times.
