Integrated control of diseases and insect pests in balsam pear

Virus disease. Harm seedlings and plants that have just bloomed and melons, make the growth point shrink, the leaves curl, the longer the plant grows, the smaller it becomes, and gradually wither and die. When the leaves begin to curl, spray 2- 3 times of 600 times of plant virus vaccine aqueous solution, or 800 times of virus A aqueous solution, or 600 times of plant growth promoter aqueous solution for prevention and control, spray once every 7- 10 days. Powdery mildew. When the disease occurs during flowering and fruiting, the leaves are covered with white powder, which causes the leaves to lose green and yellow, causes premature senescence of the plants, leads to interval flowering and fruiting and deformity of young melons, and shortens the harvest period. When white powder appears on the leaves, the leaves should be sprayed once every 7- 10 days with 1500 times of myclobutanil aqueous solution, or 1000 times of triadimefon aqueous solution, or 600 times of sulfur suspending agent aqueous solution for prevention and control, continuously spraying 2- 3 times. Melon fruit fly. The larvae bore into the young melon harm, so that the young melon deformed, and early color, then rotten deterioration, but also issued a foul smell. In the young melon stage, spray the young melon with 1000 times of Regent aqueous solution, or 1500 times of Nongdile aqueous solution, or 2500 times of green kung fu aqueous solution for 2- 3 times, once every 4- 5 days, and remove the abnormal fruit in time, burn or bury it outside the garden. Worker spider. harm leaves, suck juice, make leaves chlorosis, plant premature senescence, young melon can not expand, cause interval flowering and young melon deformity, shorten harvest period, reduce yield and quality, during balsam pear growth and development period, pay attention to check leaves, find pink needle size larvae adsorbed on leaves, namely continuously spray 2- 3 times of 1000 times of mite dead water solution, or 1500 times of mite cleaning water solution, or 1000 times of Lesben water solution for prevention and control, Spray once every 7- 10 days. Aphids, whiteflies, tea mites. Harm leaves, prick and suck juice, weaken plants, affect flowering and melon, spread viruses, aggravate the occurrence and harm of virus diseases, when aphids, whitefly and tea yellow mites are found on leaves, spray 1500 times omethoate aqueous solution, or 1000 times aphids net aqueous solution, or 1000 times a piece of purified water solution on leaves. Scarab, Lymantria, Papilio, Spodoptera. Mainly bite leaves, reduce nutrient accumulation, affect flowering and fruit, so that young melon can not expand, yield significantly decreased, after each new leaf out, spray 800 times trichlorfon aqueous solution, or 1000 times dichlorvos aqueous solution to the leaf surface for control.
