Recently, the reporter learned from interviews with the countryside that the current control of corn horses in some areas has reached a point of complete loss of control. Many farmers desperately removed all the young maize seedlings and chose to replant them. This is mainly due to the fact that there is less rain this year, which creates suitable conditions for the outbreak of sucking mouth-feeding pest P. turcicum, and that farmers’ friends have not taken preventive measures in time, leading to serious consequences. Reporters walked into the field to observe the appearance of intermittent silver-white spots on the edges of damaged maize leaves. At the same time, the thrips will release mucus in the damage of corn leaves, and the heart leaves will not be able to expand. With the growth of corn, the heart of the corn will form a "cow tail" shape, causing malformation of the plant, resulting in serious damage to the heart. The growth and development of corn. After consulting with the newspaper expert Yin Kezhong, the reporter learned that the following points should be taken into account when controlling corn humming horses: 1. For corn seedlings that have grown into "cow-tail" shape, you can use an awl to poke in from the base of the heart and leave it open from the middle to encourage the leaf to unfold and grow in time. 2. Use the habits of the horses' morning and evening activities to take the right time to spray the medicines. Usually, the spraying will be controlled before 8 am or after 5 pm. 3. Currently used imidacloprid, acetamiprid, beta-cypermethrin, spinosad and other conventional pharmaceuticals have good effects. You can use 10% imidacloprid wettable powder 1500 times and 4.5% high efficiency cypermethrin cream 1000 times. One beta-cypermethrin cannot be mixed with silicone additives. Spinosad's insecticidal effect is also very obvious, but the relatively high price. 4. Spraying In addition to spray weeds, the more important is to spray corn leaves, to cover the top spray, spray from top to bottom, rather than from the bottom up, so that the liquid into the heart leaves , kill pests and eggs hidden in mesophyll tissue.
