How to prevent and control pepper tobacco insects?

The insect body is orange-red, there are black hairs and white wax on the back, some stick to the branches of flowers and trees, some lie in the middle of the veins on the front or back of the leaves, the leaves are yellow and fall off after absorbing the sap, and the branches are shriveled, and there are also like cotton sticking to the branches and fruit stalks of flowers and trees. 50 grams of tobacco leaves, 100 grams of cigarette butts, kilograms of water, half an hour, degree or day and night after soaking, rub repeatedly with your hands, then filter gauze and sprinkle with ?2?

Sexual detergent against aphids, spider mite, cicadas, thrips, leaf insects and various other leaf-eating pests.

Chilli water. Take 50 grams of dried red pepper, add about 1 kg of water and boil for 10-20 minutes, filter and spray the clear liquid, which can control aphids, red spiders, whiteflies, etc. After repeated rubbing by hand, filter with gauze, and spray with neutral laundry detergent, it can control aphids, red spiders, leafhoppers, thrips, leaf rollers and other leaf-eating pests.

Green onion liquid: take 50 grams of green onions and mash them into a puree, add 50 grams of water, soak them for 12 hours, spray them with filtrate after filtration, many times a day, spray them for 3 or 4 days, and treat aphids and other pests.

Garlic juice. Take a kilogram of purple garlic, add a little water and soak for a while, mash the juice and dilute it with water 10 times. Spray immediately, which protects against aphids, red spiders, scabies nymphs; Pouring garlic juice into the soil prevents nematodes, earthworms.

Bacterial diseases: scabs, soft rot. Fungal diseases:

Blight, anthracnose, leaf mold, root rot. Viral diseases: specific periods of occurrence of tobacco mosaic virus and cucumber mosaic virus

Root rot: It often rains and is overwatered during the pepper production period; Put a few drops of dish soap in the watering can, shake well and spray directly. It can be used with stabbing and sucking mouthparts.

Imidacloprid, thiamethoxam, ethylspinosam, etc. Chewing mouthparts can be killed with pyrethrins.

Agricultural control: rational cultivation to reduce the source of insects; First of all, when we are plowing and irrigating in the open field, we have to kill the pupae in the soil. In early spring, you can consider planting a row of early corn in the northwest direction of the green pepper field, and the adults will fly to the corn plant to lay eggs, and then you can concentrate on removing the eggs, reducing the number of insects, and then reducing the harm; In addition, reasonable crop rotation is also very effective, such as the implementation of vegetable and rice rotation systems.

At this time, pesticides should be sprayed, because the most feared thing is pesticides, so spraying pesticides can be controlled.

Pesticides. Because after the pesticide was applied to the peppers in my house, the tobacco insects died, so I can use pesticides to control them.

Use insecticides to kill insects, after all, these insects are afraid of the chemical composition of insecticides, so they are easy to kill.

With the progress of science and technology and the development of society, many agriculture is basically mechanical integration. However, some farmers still insist on growing their own crops at home, and the food they make is not only delicious and healthy, but also does not have to worry about safety. Chili pepper is a vegetable that people love to eat very much in their daily life, not only as a flavoring agent, but also has a lot of vitamins.

So the pepper bacacia is the most common insect pest in peppers, is this insect harmful to peppers? <>

1. Absorb the juice of the pepper Once the pepper baccoratia smoker reproduces on the pepper, then these larvae will use the juice on the pepper as nutrition, and the pepper will wither for a long time. Therefore, if the farmer finds that his pepper has been attacked by pests and diseases, he must take measures in time. The most direct and effective method is to spray pesticides directly, but if you spray too much, it will also have a certain negative impact on crops, so you must pay attention to the appropriate amount.

Second, the reason why peppers can grow fast is because the soil is rich in nutrients, which can add certain nutrients to peppers. But if the bacia bacmisi multiply on the peppers, they will compete with the peppers for nutrients. For a long time, peppers have grown very slowly, and they have grown very small, which cannot meet people's normal needs.

When the farmer grows peppers, he also often goes to the field to observe the growth of peppers. <>

3. Prevention and control methodsIf you find that your pepper has been infested by the pepper smoke insect, then you must take certain measures and methods at this time. If you want to use a green and healthy method, you can also use biological control, in the most popular words, it is to attract the natural enemies of the pepper tobacco insects, so that the pepper tobacco insects will be driven away, and the peppers will be able to grow strongly. However, if you want to get a quick effect, it is recommended to spray pesticides.

It mainly pests peppers and tobacco, likes to eat pepper fruits, and also harms flowers, buds, buds, leaves and young stems. The newly hatched larvae can be harmful to day and night activities, and the amount of food increases after the 3rd instar, and they can turn plants and fruits. When the pepper is harmed, the whole body of the tobacco insect is bored into the fruit, the hole edge can be seen outside the fruit, the whole larva burrows into the fruit, gnaws and excretes a large amount of feces, only one cavity is left on the fruit surface, the pulp and the placenta are eaten, the residual peel is left, and the fruit is full of insect feces and molting, so that the fruit is inedible.

It is also very harmful, at the beginning there will be yellowing of the leaves, and it will also wither in a short period of time, so it will lead to a lot of rot and spots on the roots, and finally all of them will die, which will attract a lot of small insects.

The harm of this insect is that it will destroy the pepper, and it will affect the yield of the pepper, and it is also very contagious, and humans eating such pepper will cause diarrhea and poisoning, and it will also cause harm to the pepper, which is the harm of this bug.

The larvae of the pepper smoker insect like to eat the buds, flowers and fruits of the pepper, causing the pepper to drop buds, flowers, fruits or rot. Sometimes it also gnaws on young leaves and stems, causing holes.

It will cause a lot of spots on the pepper, and the rate of spread will be faster and faster, and the leaves will slowly rot, which will also lead to a very slow growth rate, and will cause the yield and quality of the pepper to be lower.

It depends on how much is planted, and if there is not much, you can manually remove insects. There are also chili peppers in the vegetable garden in our hometown, and there are probably two seeds that are not very numerous, and I usually dispose of these insects if I find them. For some insects that are visible to the naked eye, I basically burn them with a lighter, or crush them to death with other things, because there are not many plants, only two, so even if it is manual to remove the insects, it will not take a long time.

Of course, this method is not suitable for large-scale planting, and large-scale planting is definitely not possible, it is too wasteful of manpower. <>

Large-scale planting of pesticides for control. Pesticide killing is a relatively fast and effective way, now want to kill the tobacco green insects, in fact, the control effect is the best in the early stage, wait until these insects enter the fruit and then carry out the control, often the effect is not satisfactory, so we must be timely early detection and early medicine, which can ensure our yield, so as not to affect the growth of the fruit. One of the main characteristics of this insect is actually the larvae of some moths, if we find that there are larvae and eggs, then this period should be sprayed for a week and then continue to strengthen pesticide spraying, which can play a role in killing.

Natural predators can be cultivated to kill these insects. For example, like this red-eyed bee and this ladybug, they will feed on these tobacco bees, so you can raise some red-eyed bees when planting peppers on a large scale, so that you don't need to spray pesticides, and you can also kill the tobacco insects. <>

In addition, booby traps can be used to kill. This way of booby trapping is no stranger, moths to the fire I think everyone understands, so you can choose to use lights to trap when planting, the second day in the morning with a plastic bag to cover these insects, directly these insects are killed, which is more time-saving and labor-saving. However, we must follow the principle of early detection and early prevention, and we must do a good job of prevention in advance, rather than making up for it afterwards.

The way to control it is to go to the health center and buy pesticides, mix and match them, and mix them with fertilizers, so that you can kill these insects.

Hello! Bacillus fumigatis can be controlled with pesticides such as emamectin benzoate, indoxacarb, cyhalothrin, fenozazide, ethylspinosad, cypermethrin and so on.

Get a good **, but also be able to solve the corresponding things, pay attention to the corresponding things, especially should also use more pesticides.

Pesticides should be sprayed in a timely manner, insect pests should be removed regularly, and some insecticides and fungicides should be sprayed, and then keep sufficient light, timely watering and fertilization, strengthen water and fertilizer management, and do a good job of loosening soil and ventilation.

Our living environment will undergo various changes all the time, the first thing I have to say is that our country has been a big agricultural country since ancient times, and people's demand for food is also very large. But it has to be said that with the development of social economy, we have found that many pests endanger the health of our crops and seriously affect the harvest of the products. These include peppers and other crops.

One of the more common insect pests is the pepper tobacco green worm, so for this kind of pest, how should we prevent it, we should combine many aspects of this analysis, and then we can give the final result. <

After a long-term investigation, about 40% of the pepper fields trapped by hail will lead to low yields, and we should be aware of the need to prevent this pest. So after this kind of heavy damage to our farmland, we can take some more efficient, low-toxicity, low-residue pollution-free pesticides for prevention and treatment. Among them, the drug we generally use is 50% phosphine, this drug for this pest, their lethality is still very high, and the damage to crops is not so high, so this drug has been widely used in many places, and when we use this drug, we must choose to spray in the morning or evening, so that the effect is better.

In addition, it has to be said that this insect pest, the consequences are very serious, this larvae live in the flowers and fruits, the impact on crops is still very large, they can focus on the fruit, can eat the crop bands, etc., for the occurrence of this phenomenon, in addition to spraying control, we can also through manual capture, in addition, we can also use toxin trapping, but we must pay attention to the seedlings and the use of drugs that are safe and harmful to crops. <

You can use 50% zinc thion, 40% emulsifiable concentrate, 80% dichlorfon soluble powder brightening agent, deltamethrin emulsifiable concentrate, 20% fenvalerate milk Jinghe oil, etc., these things can kill this disease and insect pests, are very good.

Generally, you can choose 50% phosphine EC, 50% pine borer EC, 40% acemethamide phosphate EC, 80% enemy creep 100 insect soluble powder, etc., or deltamethrin EC, 20% fenvalerate EC, kung fu methrin EC, 5% cisvalerate EC, these drugs can be prevented.

It can be used to infiltrate 800 times of trichlorfon, 3000 times of dichlorofenthrin, 4000 times of cypermethrin, 3000 times of pyrethrin and 4000-6000 times of dichlorofenthrin.

You can directly use some chemicals, and then you can also spray some pesticides, so that you can prevent well.

Bisamide insecticide, this pesticide is very useful, and it is very good for ** insect pests.

First of all, when planting, we must choose the soil is relatively fertile and wide land, and in the process of fertilization, we must use farmhouse fertilizer, do not use fertilizer bought outside, but also often water the plants, and also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. In this way, you can prevent the chili smoke insects.

Some weeds should be cleaned up in time, and fertilizer and watering should be applied in time, and the density of planting should be paid attention to the seedlings, and some drugs can be used if necessary.

It is necessary to spray some pesticides in time to kill these pests and diseases, and then remove the problematic plants in time.

1. Planting tobacco to induce overwintering adults to lay eggs. Because the overwintering adults have a strong orientation to tobacco, the overwintering adults can be induced to lay eggs to facilitate centralized elimination.

2. Ploughing and pupation in winter; Reduce the number of worms in the coming year.
