There are many species of locusts, and the main peach plants are peach aphid, peach aphid, and peach aphid. These locusts all attacked the leaves when the peaches sprouted and spread, and the Cheng and Ruoqiang groups gathered on the back of the peach leaves and sucked on the shoots. The damaged leaves show black, red or yellow spots, gradually turning the leaves into white curls, causing defoliation in severe cases, weakening the tree vigor and affecting the yield and flower bud formation of peach trees. Therefore, it is necessary to pay attention to timely chemical control. Timely application The best period for the prevention and control of pesticides is the dew-green buds of peach leaves. When buds buds, they can be used once, and then they can be used for 1 or 2 times depending on the situation of the insects. Each medication must be before the leaf is wound, otherwise Will affect the control effect. Control methods 1. 50% sprayed pesticide can be used to spray fog 3000 to 4000 times or 50% phoxim EC 1500 times or 50% malathion EC 1000 times or 10% imidacloprid WP 5000 times etc. . In order to improve the control effect, a certain amount of spreading agent can be added to the drug solution, and several agents are used alternately to avoid using a single agent. 2. The agent is dried with 1 part of 40% Dimethoate, 1 part of multi-functional plant synergist, 2 parts of water, mixed and mixed with liquid medicine, and brush the trunk with a brush about 10 centimeters wide. If the bark is rough, the old rough skin can be scraped off and then coated. After coating with a newspaper or plastic film can be better. 3. The trunk injection is on the trunk with an iron cone penetrating upward from the top and down to the xylem, then inject 40% Dimethoate EC 1ml into the needle and then close the orifice. After 2 or 3 days, the trunk can be closed. More than 95% of locusts kill. 4. There are many natural enemies for the protection of natural enemies, such as ladybugs, hoverfly, grasshoppers, parasitic bees, etc., which have a strong inhibitory effect on aphids. Therefore, it is necessary to spray as little as possible with broad-spectrum insecticides and to avoid spraying during natural enemies, in order to protect natural enemies and use natural enemies to eliminate aphids.
