During the production of cowpea, there are more pests and diseases. Recently, when interviewed by the Provincial Agriculture Department's plant protection experts, the reporter found that in addition to conventional pesticides , there are also high-efficiency and low-toxic pesticides. The price is not high and the effect is remarkable. All cities and counties in the province can buy them. Pea pods are the most common pests of cowpea. The anterior wing of the worm is long and narrow, with a white longitudinal band along the leading edge and a golden yellow wide transverse band at the third of the proximal wing. The old larvae have a "human" shape black spot in the center of the chest. Its hazard is that the larvae feed on the beans in the pods, the light ones bite the beans into holes, and the heavy ones bite the whole pods. Cai Dejiang, the station manager of the Provincial Agriculture Department's Plant Protection Station, said that in order to control the pests of the pea pods, it is necessary to remove the fallen flowers and pods in the field and remove the damaged leaf and pods to reduce the insect source. In the prevention and treatment of pesticides, farmers are accustomed to using traditional pesticides. Although the effect is good, it needs to be used frequently. It should be sprayed once every 3 to 5 days, and the safety interval is longer. Generally, it can be picked 7 days after spraying. Nowadays, there is an imported medicine on the market called chlorantraniliprole suspending agent. Although the price is twice that of ordinary medicine, it can be effectively sprayed once for 15 days. The comprehensive cost is still lower than traditional pesticides. More importantly, this agent has no toxic side effects, and it is used in some countries in the West to produce organic foods because it ensures food quality and safety. This highly effective and low-toxic agent is used in a 5% chlorantraniliprole suspension, once every 15 days, and 2 to 3 times in a production season. Especially in the prevention and control of pea pods before harvest, this agent works best. Cowpea also has a common pest - the hummer. This insect breeds faster in Hainan, with the peak season of winter melon growing. Its harm is that sucking heart leaves, tender stems, flower organs and young juice liquids, causing fruit drop and rough skin, have great influence on yield and quality. Cai Dejiang said that the best medicinal agent for the control of cowpea is the ethyl spinosad suspension, which not only has good effect, but also has a short safety interval. Picking after 3 days of spraying can also ensure quality and safety. This agent is used by spraying 3 to 5 heads per plant and using a 60% ethyl doxorubicin suspension 1500 times. Compared with other similar pesticides, this drug is not expensive. Cai Dejiang said that there are many kinds of pesticides for the control of cowpea pests. If a pesticide is used for a long time, pests will develop resistance and are not conducive to prevention and treatment. Therefore, it is recommended that farmers should not use one pesticide frequently when selecting pesticides, and use other low-toxic pesticides.
