How to control the cowpea insects planted?

If it's not particularly serious, you should apply some pesticides at the early detection to kill the worm in the cradle.

See what kind of bug it is, and then use an insecticide suitable to kill this bug, so that the treatment will eliminate the bugs on the cowpea.

Cowpeas have insects, you can also spray pesticides. Try to choose pesticides with relatively low residues.

Spraying treatment, generally this is the way to govern.

Self-grown green products also need to be insected. Otherwise, the bugs will become a disaster to survive.

The insects are caused by the humid environment in which the dried beans are located. Therefore, after buying dried beans, they should continue to dry in the sun for a day, and then put them in a sealed jar and store them in a cool and dry place after they are thoroughly dried.

Be sure to dry in the sun, and then store it in a cool, dry place in an airtight jar, or in the refrigerator if possible. It can also be dried and stored in a plastic bag in the freezer, which has a better effect.

Before storage, you need to screen out the bad and long worms, and then seal it with a lock, and you can have a clean bag, but you must ensure that the bag is dry and must be sealed.

I can't eat it, so I can only throw it away.

First of all, it should be sown in June and July, and the temperature should be higher, and some pesticides should be sprayed at the same time, and some sterilization drugs should also be used, so that it can be well controlled, and some nitrogen fertilizer, phosphate fertilizer, organic fertilizer should also be applied.

You can use some lights to trap and kill adult insects, and you should clean up some weeds in the field in time, and use some drugs to spray these insects, which can also increase the moderation of the field.

If you want to deal with the cowpea insects that are planted, you should spray some insecticides, which are very effective.

Answer]: 1. Before sowing, the soil should be treated with insecticide, and the agent should be added with a new high-fat film to enhance the efficacy of the drug.

2. Strengthen fertilizer and water management. The emergence of seedlings is consistent, the growth is neat, and the flowering and podding period is relatively concentrated, so as to concentrate on eliminating the insect during the critical grinding period.

3. Pay attention to the prevention and treatment of pharmaceuticals. Spray the larvae in the flower buds before the flowering period. After flowering, the pod grows into more than 10 centimeters long, and when sprayed once, it can kill the young larvae that have hatched and bored into the young pods.

The agent uses kung fu 1500 times liquid (or avermectin 1500 times liquid spray, or Aruibao emulsifiable concentrate 1000-2000 times liquid) + new high lipid film 800 times liquid The effect is better than grip leakage.

<> can be sprayed with 40 dimethoate or 80 dimethoate rotten divos emulsion 1000-1500 times; Spray 1000 times of Yubiyan vine essence; Spray 60 times of lime water (need to add washing powder) and other methods to control cowpea aphids.

To start the control of carob borer insect pests during the flowering period of carob, imidacloprid and cyhalothrin can be used, which can have a good control effect.

The bean borer is warm-loving and occurs for many generations a year. The first hatching larvae are infested by borrowing flowers. After the third instar, the pods eat beans and have the habit of turning pods many times, and their feces accumulate.

It often causes pod rot. Cause flower drop, pupation and cocooning in October to overwinter in weeds and soil. The adult body length of the bean borer is about 13 mm, the body is dark yellow-brown, the back of its wings is about 25 mm, the ** part of the forewings has two white transparent spots, the hindwings are white translucent, and there are dark brown wavy stripes on the inside.

<> eliminate the adult worms, reduce the source of infection, completely remove the dead vines, fallen leaves, and damaged pods on the previous stubble, and in winter, deeply turn the land to destroy the wintering place of the pests. Chemical control: spraying with chlorantraniliprole, perchloramectectin benzoate, fenozide, indoxacarb and other agents, do not control pod borer to emphasize an "early treatment", must be in the peak of incubation control, once the larvae drill into the flower bud or pod after increasing the difficulty of control.

Avoid heavy cropping, do not crop with leguminous crops, and stay away from the plots where leguminous crops were planted in the previous year and the plots where leguminous crops have been planted in the current year. In this way, we can "avoid" the phenomenon of the nearest harm of the pod borer and reduce the source of insects; Clean up the places where the pod borer overwinters, and if possible, the field can be set up without black lights, and the adults of the bean pod borer can be trapped, so as to reduce the number of insect sources. Choose varieties with early maturity and high yield, short pod setting period and insect resistance to reduce the harm of pod borer to cowpea.

From the beginning of the pod setting period of cowpea, it is necessary to use regular medication in a timely manner, and generally prevent and control it twice in a row.

In rural areas, physical methods are often used to kill them: adults can be trapped at night with incandescent lamps and black lights. After the crop is harvested, the field should be cleaned in time, the residual branches and leaves should be swept away, and the frozen stubble of the soil should be deeply turned in winter to eliminate the overwintering insect eggs.

Generally, it is found that 2-3 days after the increase of insect moths is the egg incubation period, at this time the best effect of the drug, generally you can choose emamectin benzoate plus cyfluthrin, Ruijinte, cyantraniliprole and other insecticide spray, should be together with flowers, buds, pods, etc.

Beans can be controlled with plant ash for insects. Many beans will encounter a variety of insects in the process of growth, the carob leaves are eaten sparsely, and the soil method in the countryside is to sprinkle grass ash on the carob leaves, which can prevent insect pests, so that you can eat at ease.

At this time, you should spray a large number of pesticides, after all, this situation will cause a decrease in yield, and when you encounter this kind of problem, you should choose to solve it as soon as possible, otherwise there will be more serious problems in the later stage.

1. Remove fallen flowers and pods in the field in time. Clear the ground in time after harvest to reduce the source of insects.

2. Place a black light in the field to trap and kill adult insects. From the beginning of the month to the end of August, all carob fields in the flowering period generally must be medicated twice (once each in the first flowering stage and in the full flowering stage). At 8 to 10 o'clock in the morning, when the carob flowers are opened, the medicine is used, and the prevention and control effect is the best.
