How to control diseases and insect pests of balsam pear? The pests that are difficult to control are melon fruit fly, melon aphid and melon silk borer. 1. Melon fruit fly: commonly known as "needle wasp", adults lay eggs in melons and fruits, and larvae eat in melon flesh, resulting in melon rot and even fruit drop, seriously affecting the quality and yield of melons. At present, it is the peak period for the emergence of needle wasps, and the comprehensive management methods of pastoral cleaning, trapping and killing adults, insecticides and bagging melons are adopted. It is recommended to use kung fu to kill insects with chemicals. A small bag (5 ml) of Kung Fu on the market can be exchanged for a bucket of water (15 liters). Spraying is carried out before 10-11:00 in the morning or 4-6 in the afternoon during the peak period of adult activity, and the effect is better during the adult mating and spawning period. One of the ways to trap and kill is to use yellow board, yellow cardboard or glue board coated with Vaseline in the vegetable garden, about 20 yuan per mu, which has a better trapping and killing effect on adults. Vigorously popularizing the new technology of bagging and protecting melons can not only reduce the damage of various diseases and insect pests, but also improve the quality and commodity value of melons and fruits. 2. Melon aphid: the adults and nymphs of melon aphids are clustered on the back of leaves, tender stems and shoots to absorb juice. The insect will damage the shoot, the leaf curls, the growing point dies, the leaf shrinks, yellowing and shedding ahead of time, it can also cause soot disease and spread virus disease. Pesticide control recommends 25% Aktai water dispersible granule with high efficiency, broad spectrum, safety and lasting for 21 days, which can effectively control melon aphid and many other pests such as thrips and Liriomyza huidobrensis by using 5000-10000 times. 3. Melon silk borer: the larvae gnaw on the leaves, resulting in perforation or engraving of the leaves, which are often eaten into the melon, affecting the yield and quality. Use 50% curon 1000 times or 2.5% kungfu 1500 times spray every 7-10 days. Click to get more balsam pear planting techniques click to get more vegetable planting techniques
