The invention with the application number CN201510495917.8 discloses a watermelon pest control method, which includes the following control steps: (1) Seed sterilization: a. spread out the watermelon seeds, expose them to the sun for 3-5 hours, and flip them every hour; b. .Put the watermelon seeds after soaking into the salt water with a concentration of 8-12% and soak for 0.5-1h; (2) Clean up the melon field: remove the weeds in the melon field and the peripheral 5-8m of the melon field, and sprinkle them on every square meter Go into 120-150g lime powder, sprinkle into 180-250g sulfur powder per square meter after two days; Spray once a day for prevention and control, spray 3-4 times; b. Dilute 20g of Jinjier wilting water to 12-15kg, spray once every 10-12 days, spray 2-3 times; (4) Flowering period: a. Dilute 0.2-0.4% azadirachtin 800-1200 times, spray once every 10-12 days, spray 4-6 times; b. Dilute 20g of Jinjier with water to 8-10Kg, every 8-10 days Spray control once, spray 2-3 times; this method has a certain effect of pest control, but if the underground pests in the melon field cannot be removed first, and the seeds cannot be covered with film for protection, the watermelon seed stage is vulnerable to gnawing by underground pests, etc.
