The cabbage has a pest and I don t want to spray, how to solve it?

Insects can be caught manually in the evening or in the morning. In rural areas, many people do this, and choosing this time to remove insects is the most effective.

Neem seed leach.

Spraying with a small watering can can prevent and control leaf miner flies and whiteflies, and although aphids and noctuidae cannot be directly killed, they can be expelled anyway.

Laundry detergent water. Simplest, Dege still likes to use laundry detergent mixed with water to deal with these pests. Compared with the first two spicy eyes and choking nose, laundry detergent water is colorless and odorless, much milder, but the effect is leveraged.

The preparation is also simple, 1 gram of laundry detergent + 200 grams of warm water melts. When using, add a little cooking oil to increase the viscosity, spray the cabbage once, aphids, red spiders, whiteflies, night worms, these pests, for a period of time is not visible.

The scientific name of the insect is aphid. The following medications can be taken for aphids**

1. Spray the plants 1 2 times with 1000 times of 50% marathon emulsion, or 1000 times of 50% pine borer emulsion, or 3000 times of 50% anti-aphid wettable powder, or 3000 times of deltamethrin emulsion, or 3000 times of dissol emulsion, or 1500-2000 times of 40% imidacloprid water solvent.

2. Prepare chili water with a ratio of 1:6-1:8 (boil for about half an hour), or use 1:

20-1:30 ratio of the preparation of laundry detergent water spray, or with 1:20:

The ratio of 400 is sprayed with a mixed solution of laundry detergent, urea and water, and the plants are sprayed 2 or 3 times in a row.

What should I do if the cabbage attracts cabbage worms? No need to use pesticides, simple tricks to deal with it easily!

Just planted the cabbage just two leaves have small eyes, and I can't see the insects, what should I do.

It depends on what kind of insect it is, there are ground pests such as cabbage worms and aphids, as well as underground pests such as ground tigers and mole crickets, and the medication is completely different.

This is Spider-Man, it's not a bug, a spider isn't a bug.

Cabbage does not apply pesticides to treat insects:

1. Before planting, the film can be used to cover the planting ground to kill the adults and eggs in the soil through light and high temperature;

You can choose continuous high temperature weather, mulching in the morning, and enhancing the ground temperature through high temperature evaporation at noon, so as to suffocate the insect pests in the soil; It can reduce and inhibit the occurrence of insect pests in the process of Chinese cabbage planting.

2. Artificial insect catchingIf the cabbage has been infested, it is necessary to identify which insect pest is infesting the cabbage; In the morning, manual insect catching can be used to reduce insect pests;

In general, bok choy is susceptible to aphids, borers, diamondback moths, cabbage worms, and maggots; Artificial insect catching can effectively reduce the damage of borborer and cabbage worm.

Cabbage does not use pesticides usually use the following four soil methods to control cabbage pests: the longest use is to sprinkle ash (plant ash) on the leaves after the cabbage insects, which can play a good role in the prevention and control of aphids, cabbage insects and other pests, and the principle of action is that the fine particles formed after the ash is dispersed can block the stomata of pests, thereby killing pests. Grass ash will not hurt cabbage leaves, but if the amount is too large, the attachment time is too long will affect the photosynthesis of the leaves and affect the growth rate of cabbage, so when using plant ash to prevent and control cabbage diseases, sprinkle a thin layer, it is best to sprinkle the day before the rain, so that the residual plant ash can be washed off in time through rainfall.

Then there is cabbage and these aromatic vegetables interplanting, which can play a role in reducing insect pests, such as: cabbage interplanting celery, which can significantly reduce the occurrence of thrips; Intercropping of cabbage with onion and garlic can effectively reduce the damage of aphids and red spiders. There are also including garlic, onion, mugwort and other plants of the stems and leaves and other organs in the solution formed after soaking or cooking, contains the components that can kill pests, by spraying this kind of plant leaching solution can also play a role in killing cabbage pests, with this insecticidal effect of the plant more, the methods commonly used include:

After mashing the onion and garlic, add 25 times the water and stir well to mix well, and take the supernatant to spray the cabbage leaves after stationing, which can effectively kill aphids, red spiders, scale insects and other pests; Take green mugwort leaves, pound them and boil them in boiling water that is 10 times the volume for 30 minutes, and spray them with supernatant, which can effectively control pests such as cabbage worms and aphids; Take the fresh stinky Tsubaki leaves and mash them, add 3 times the volume of water, boil for 30 minutes and then stand still for 3 days, take the supernatant and dilute 40 times and spray the cabbage leaves, which can effectively control cabbage insects and aphids. There are also similar insecticidal effects of Zanthoxylum pepper leaves, Zanthoxylum bungeanum pepper, ginkgo biloba, honey locust, etc. The above is the insect control method of cabbage without pesticides, I hope it can be used for reference.

Hello, glad to answer for you. Insect control methods without spraying pesticides:1

Kill each other in kind, treat cabbage worms with mashed cabbage worms mixed with washing powder, and then sprayed with water. The specific method is to catch some cabbage worms on the cabbage, and then soak them in water for 24 hours, and after the decay and deterioration, spray the cabbage with the rotten liquid with water and washing clothes, which can effectively control the cabbage worms, and there is no pollution, and the cabbage grows vigorously, which is equivalent to spraying foliar fertilizer. 2.

Green onions can be used for control, garlic juice can be used for control, and garlic juice can be used for treatment in the peak season of aphids. The specific method is to take 2-3 garlic heads and a loofah, then mix and mash, and then spray the cabbage with water. You can also mash it with green onions and water, and then spray the cabbage evenly with an appropriate amount of water, which can also control cabbage worms.

3.Interplanting at intervals, so that cabbage insects are far away from each other, do not let cabbage grow in pieces, cabbage growing in pieces is conducive to the reproduction and climbing of cabbage worms, you can take the method of interplanting, and garlic, peppers, eggplants, tomatoes and other vegetables with a strong taste are planted together, so that the smell of these emitted smokes the cabbageworms, which is not conducive to the growth of insects, and then realizes the purpose of insect repellent. 4.

Spraying or sprinkling plant ash directly on the leaves is not only a fertilizer, but also an insecticide, and proper use can play a role in insecticide and foliar fertilizer. In the prevention and control of cabbage insects, you can first soak the plant ash for a whole day, and then spray the soaking solution with water, or you can use the plant ash to sprinkle the cavity directly on the leaves, which can touch and kill the cabbage insects.

If you have to spray a large amount of clean water early to dilute the pesticide concentration on the cabbage leaves, so as to reduce the degree of pesticide damage. Because of the pesticide damage caused by the spray of the leaves and plants, if it is found in time, when the liquid Xiaoboling has not completely penetrated into the plant, you can quickly spray the damaged plants with a large amount of water, 2-3 times in a row, and try to wash off the drug on the surface of the plant, which can well alleviate the continuous development of the pesticide damage. At the same time, it is recommended that we add the alkaline surface in the sprayed water, because most pesticides are acidic, and the neutralization reaction will occur when encountering alkaline substances, reducing the efficacy, so it can speed up the decomposition of the agent, thereby reducing the pesticide damage of crops.
