Pepper borer is the main pest and disease of green pepper, how to control pepper borborer?

When we plant many plants and crops, some pests and diseases will occur, such as some pepper borer diseases will occur when planting green peppers, which is the main pest and disease of green peppers, and it also constantly affects the yield of green peppers. For green peppers, it is a frequent occurrence of pests and diseases in summer and autumn, even if many people say that they spray a lot of pesticides, they still can't control this pest and disease, so we need to come up with certain measures to prevent and control.

Characteristics of the hazardIf we want to fundamentally prevent the emergence of pepper borborer, then we need to understand what its harm is, they will appear on the leaves of peppers at the larval stage to harm their stamens and fruits. In the beginning, the larvae will suck the epidermal tissue on the surface of our peppers, causing our peppers to have some holes, and as it grows, it will start to eat our young pots. Until its food begins to increase, it will devour the pulp, and even continue to reproduce and parasitize, and it will come out more at night.

Control measuresWhen we are planting, if we want to control pepper borerworm, we need to catch it from the time it is born. Because many times the appearance of pepper borer is because we are ploughing, or when we dredge the soil, some bacteria cause some bacteria to contaminate the leaves. Therefore, when they are just born, they need to use some pollution-free pesticides for efficient spraying.

Because they reproduce very quickly and they come out more at night, it is best for us to be able to control them during the day, so as to reduce the effect of them coming out at night to prey on the peppers we grow.

Precautions: Many larvae are caused by the lack of effective control in the early stages, which leads to their continuous reproduction, which affects the yield of our planting. When we loosen the soil, we often fail to disinfect the seeds, which will cause bacteria to infect the soil and cause the crops we grow to be infected with pests and diseases. We must pay attention to hygiene and cleanliness when protecting these crops, reduce the breeding of bacteria, and effectively prevent pests and diseases.

We can turn the soil frequently, so that we can also turn these insects out, or we can trap them by lights, and put some black lights at night. It can also be booby-trapped with sweet and sour liquid, with white sweet and sour liquor in a certain proportion to form a bait, or it can be sprayed on the leaves of peppers through some medicine.

Grasp the prevention and control strategy, seize the prevention and control period, select high-efficiency, low-toxicity, low-residue, pollution-free pesticides, and also take winter ploughing, water and drought rotation to kill pupa and so on.

The fastest solution to this pest and disease is to spray the corresponding pesticides in time, and to water in time, fertilize in time, and supplement light.

It can be prevented and treated with pyrethrins, avermectin, emamectin benzoate and other agents. The worm can harm rice, corn, sugarcane, beans, apples, pomegranates, peach trees and other crops, and the prevention and control will cause serious harm to plant leaves, stems and fruits and other organs.

You can use emamectin benzoate, indoxacarb, chlorantraniliprole, flubellurea, tetrachlorantraniliprole, and so on, and the effect is very good.

Emamectin benzoate, this chemical can directly kill all the insects, and it is also a chemical agent often used when planting green peppers.

<>1. During the peak hatching period of larvae, spray 5000-6000 times of kung fu emulsifiable concentrate and 800 times of new high lipid film, or spray 1000 times of microbial pesticide "HD-1" and 800 times of new high lipid film. 2. During the peak hatching period of larvae, spray 2000-2500 times of 20% metmethrin EC, or 5000-7500 times of tetrabromothrin EC, spray 1 time every 6-7 days, and spray 2-3 times in a row.

1. What kind of agricultural medicine is used for pepper borers

1. During the peak of larval hatching, spray 5000-6000 times of pyrethrin splitting pesticide rapid killing, Lyflexin, Kung Fu emulsifiable concentrate 800 times of new high lipid film and other drugs in the morning or evening, or spray 1000 times of microbial pesticide "HD-1" and 800 times of new high lipid film.

2. At the peak of larval hatching, spray 2000-2500 times of 20% metpermethrin EC, or 5000-7500 times of tetrabromothrin EC, or 2000-4000 times of flaccofthrin EC, or 3000 times of 5% cis-permethrin EC, spray once every 6-7 days, and spray 2-3 times continuously.

3. 10 days before the first picking of peppers, it is necessary to stop using drugs, and if you still want to prevent and control them in the future, you can only use biological agents, you can use 50-100 grams of indonin emulsifiable concentrate with 50 liters of water per mu, and then spray, which can not only control insect pests, but also do not harm natural enemies, and will not cause pollution to the environment.

Second, the harmful symptoms of pepper heartworm are Changxin

1. The larvae will eat the buds, leaves, buds and fruits of the pepper, and the pepper fruit that has been eaten will have obvious holes (the whole larvae will generally burrow into the inside of the pepper fruit), and the larvae will also discharge a large amount of feces, resulting in the entire pepper fruit being inedible, and the pepper fruit will rot when the situation is serious, causing a large number of fruit drops.

2. The hatched larvae will first feed on the egg shell, and then on the epidermal tissue of the young leaves, forming holes or notches. The first instar larvae feed day and night, and the amount of food increases after entering the 3rd instar stage, and at this time they have the ability to transfer plants and fruits to harm, and generally lurk under the host leaves or soil crevices during the day, and come out at night to move.

3. After the larvae emerge into adults, they will lay eggs at the veins of the upper leaves (front and back) of the host crop in the early stage, and generally lay eggs on pepper fruits, sepals and petals in the later stage, and each place can lay 1 egg, or 3-4 eggs gathered in one place.

Seeds are soaked and disinfected, seedbed soil is disinfected, and crop rotation is implemented with other non-solanaceae crops. **Method: Spray with 70% methyl ketone, not only 1000 times the liquid of visible powder, once every 7 days, 2 3 times in a row.

Clean up the soil and remove the debris and leaves, dig deep into the soil or disinfect the soil to eliminate the source of insects. **Method: It can be sprayed with 10% imidacloprid wettable powder 1000 times, kung fu emulsifiable concentrate 2500 times, and 5% fipronil emulsifiable concentrate 1500 times, once every 5 days, 4 5 times in a row.

In the selection of varieties, choose varieties with strong disease resistance to fundamentally reduce the occurrence of diseases; secondly, select plots with higher terrain and good drainage, strengthen field management, and reduce the occurrence of diseases; Third, drug prevention and control.

It must be planted scientifically and fertilized reasonably. select excellent varieties that are resistant to viruses and disinfect seeds when sowing; Try not to rotate with nightshade vegetables and re-recommend planting. Do a good job in field management of peppers with pests and diseases, agricultural measures:

We place the seedbed on a leeward, well-drained, well-lit plot that is conducive to moisture drainage; The temperature is controlled at 25-28 degrees, and the ground temperature is kept above 16 degrees to prevent low temperatures.

For anthrax, difenoconazole or fluridine or azoxystrobin can be used to spray the whole pepper tree with water. For pepper blight, the diseased strains should be removed first, and then sprayed with azylester bacteria or fluridine or enoylmorpholine mixed with water. For places exposed to direct sunlight, shade nets should be used to cover them to avoid direct sunlight on the fruits; Appropriate irrigation to replenish soil moisture; Remove diseased fruits in time to prevent the invasion and spread of germs.

The control of pesticides can be 500-600 times of 75% chlorothalonil, or 500 times of 70% mancozeb, or 500 times of mancozeb, or 1:1:200 Bordeaux solution, or 500 times of 77% killable powder, and the above agents are applied alternately to avoid drug resistance.

Peppers can be sprayed with pesticides. Some pesticides can eliminate aphids.

I think pepper aphids are a very common insect pest, and if we want to better control pepper aphids, we should take measures in advance and spray some ** aphid drugs on the surface.

Silver-gray membrane repels aphids. Silver-gray has strong repellent properties against aphids, and silver plastic strips can be hung in the field or vegetables covered with silver-gray mulch. Laundry detergent is out of print. The main ingredient of laundry detergent is sodium dodecylbenzene sulfonate, which has a strong contact killing effect on aphids.
