Before winter melon planting, seed disinfection is generally carried out, mainly to remove the source of the disease, mainly including blight, stagnation, powdery mildew, downy mildew, root rot, and bacterial wilt.
Control method: Each kilogram of seed is mixed with Luheng No. 1 (99% carbaryl) 0.5-1 g + Luheng No. 2 (Duofu Zinc), and can be mixed with dry and wet.
Second, seedbed disinfection
After the seedbed disinfection, mainly to remove soil pathogens, mainly blight, stagnation, root rot, bacterial wilt, anthracnose and so on.
Control method: use 0.5-1g of green hen 1 + 4g of green hen 2 per square meter and mix 20kg of fine soil. After mixing well, half of it will be sprinkled on the noodles, and half of the seeds will be covered. Or use the Green Hunting No. 9 to spray the surface.
Third, prevention and control during seedling
The main control objects of winter melon seedlings (30-50 days) are: squatting disease, blight, root rot, aphids, and key roots. From the seeding of melon seeds, to the cotyledons growing out of the soil until 4-7 pieces of true leaves grow, lasting 30-50 days, the focus of this stage is long roots.
Control method:
Use Luheng 4 + Tianbao (rotation to root use) + Shidingkang spray, prevent disease and pests and promote roots and strong seedlings.
Fourth, prevention and control during the pumping period
During the convulsion period (10-20 days), the main control objects are: downy mildew, powdery mildew, aphids, thrips, whitefly, and leafminer. The melon seedlings have 6-8 true leaves, and the tendrils begin to be extracted. Some begin to grow long flower buds. From erect growth to sorghum growth, the leaf area expands rapidly, and the side vines begin to differentiate. Generally, it lasts for 10-20 days. leaf.
Control method:
Use Hurricane + Dinger Carvacrol + Shidingkang Spray to prevent red spiders with 哒螨 脒 or avermectin.

Winter melon is budded until the fruit is ripe. It is a period of strong growth of winter melon. The melon is continuously flowering and fruit set. The focus is on the preservation of the fruit and the supply of phosphorus and potassium fertilizer.
Control method:
Sweeping powder + butyl carvacrol + flower + cloud Wanbao + green hen 106 spray, or use charcoal lock + green heng 6 + SM6 + Shun Fanning spray, or use hurricane + butyl carvacrol + Tianbao + love autumn spray The above formula is rotated for 7-10 days. During this period, winter melon requires a large amount of phosphorus and potassium fertilizer, which can be used to root or rush to apply cola root or spray to supplement nutrients.
The above is about the introduction of pest control in the five periods of melon. From the above, we can see that the pests and diseases are different in different periods of winter melon planting, and the control methods are different.
