1、 Medicament seed dressing

The so-called medicament seed dressing is to mix an appropriate amount of medicament with seeds before planting, and then sow. The medicine can protect the seeds, which is also the first coating. After the seeds germinate in the later stage, spray the medicine once and coat the heart twice, so as to effectively prevent aphids

2、 Spraying fertilizer

In case of aphid damage to corn, brush off the pests with a brush as soon as possible, and then spray imidacloprid and methoxam as soon as possible. It can be controlled once every other week, about three or four times. In addition, it is not only possible to spray when there are pests. It can also control pests by doping an appropriate amount of chemicals in each fertilization

3、 Improve the environment

When there are aphids, in addition to spraying drugs, we should also improve the environment. Usually, the disease is caused by high temperature environment or poor ventilation. Weeding should be carried out frequently to ensure ventilation, which can effectively reduce the harm of aphids. In addition, when planting, it is best to plant it in a place with good light. If the light is sufficient, the probability of infection with aphids will be reduced
