Wax gourd planting: how to prevent and cure wax gourd gray mold?

How to prevent and cure wax gourd gray mold? Please introduce the effective control methods of wax gourd Botrytis cinerea can be controlled by the following methods: 1. Select disease-resistant varieties. 2. Select the disease-free seeds, leave the seeds from the disease-free shed and disease-free plants, and use the frozen filter paper method to test whether the seeds carry bacteria or not. 3. Soaking seeds with warm soup or medicament: good germicidal effect can be obtained by soaking seeds with 55 Mel 60 ℃ at constant temperature for 15 minutes, or 50% carbendazim wettable powder solution for 20 minutes and then rinsing and then sprouting, or with 0.3% carbendazim 50% wettable powder. 4. Mulching plastic film, adopting water-saving techniques such as drip irrigation, crop rotation, serious disease greenhouse (field) and non-melon crops should be rotated. 5. Fumigation and disinfection: 10 days before planting in greenhouse and plastic shed, 0.13 kg of sulfur powder is used for every 55 cubic meters of space, 0.25 kg of sawdust is mixed and placed in several places, lit and sealed in the greenhouse for one night. 6. Strengthening cultivation management: it is very important to control watering from planting to melon setting stage. In protected cultivation, ecological control should be adopted as far as possible, especially temperature and humidity management, ventilation and humidity drainage, control of irrigation and other measures to reduce humidity in the greenhouse, reduce leaf condensation, inhibit germ germination and invasion, control temperature 28 ℃ in daytime, 15 ℃ at night, and relative humidity less than 90%. The incidence of the disease can be reduced by controlling the average temperature of the medium-temperature and low-humidity greenhouse at 21ml 25C, or controlling the humidity of the greenhouse above 90% for no more than 8 hours. 7. At the initial stage of the disease, the dust or smoke method began to spray more than 10% dust spray with a powder sprayer, or 5% anti-black star dust agent 1 kg per mu, or applied 45% chlorothalonil smoke remover 200 grams per mu, continuous prevention and control for 3 times for 4 times. 8. Spray 8000 times of 40% Fuxing EC or 50% carbendazim wettable powder plus 70% mancozeb wettable powder, or 2% BO-10 aqueous solution plus 50% carbendazim BO-10 in greenhouse or open field. Or 75% chlorothalonil wettable powder 600x liquid, 50% carbendazim wettable powder 1500 times liquid, 80% carbendazim wettable powder 500x liquid, 60mu 65 liters per mu, once every 7ml for 10 days, continuous prevention and treatment for 3 times. 9. Strengthen quarantine to prevent the spread of the disease. Click to get more wax gourd planting techniques click to get more vegetable planting techniques
