Cabbage insects on radish and cabbage are rampant, how to solve it if you don t use pesticides?

You can use the method of interplanting, in the cabbage, radish field, interplanting pepper, garlic and other spicy vegetables, these vegetables will exude a special strange taste in the growth process, directly make the cabbage worm escape from the vegetable garden from a young age, so that it can have the effect of repelling insects. If you grow more vegetables, it will be too slow. Then come to a method of insect control, when there are cabbage green worms on the cabbage radish, catch a part, and then mash it and soak it in water for half a day, then filter out the residue, add laundry detergent and spray.

It only eats the mesophyll part of the leaf, so we can always see that the leaf has only two skins left, which is actually eating the mesophyll. When it grows up a little, its mouth becomes thicker, and it doesn't pick anything to eat, even the belt meat goes down, and the so-called "insect eyes" will appear on the leaves. The leaves are bitten in the east and in the west, which affects the growth of radish and cabbage.

After all, these are all home-grown, so that you can eat organic vegetables without any pesticides, so that you can be healthy. At present, there are several of them that are widely used in rural areas, and I think the effect is not bad.

White and silver-grey mulch cover repels aphids and reduces the damage of aphids. Using the yellowing nature of aphids to hang yellow sticky aphid plates, a large number of winged aphids and leafminers can be killed. The first method, if there are not many insects, you can directly catch the insects on the leaves with your hands.

Some people are afraid and dare not catch it directly with their hands, or they can use two small sticks to clip it down, and it is best to turn over the leaves to take a look when catching, because cabbage insects often hide on the opposite side of the leaves.

One is to use Artemisia annua to expel it. In our local villages, wild Artemisia annua can be said to be everywhere, so rural people often make rational use of resources, cut off wild Artemisia annua, and put it into manure ponds, latrines or fields, which can kill bacteria, insects, and fertilizer. It seriously affects the growth and development of radish and cabbage plants, resulting in reduced yield, and even affects the core of the damaged cabbage.

Damaged radishes and cabbage are full of insect mouths, and they are also very susceptible to infection by germs, inducing diseases such as soft rot, so they may cause more serious losses.

If you don't use pesticides, you should water radishes and cabbage more and apply more fertilizers to them.

Grass and wood ash from the countryside can be used to control cabbage insects. The plant ash is collected and then mixed with water. The proportion of mixing depends on the situation, and generally the water is 1 3 times that of plant ash.

If the infestation is severe, add less water. Soak the ashes in water for more than 12 hours, then filter out the soaking solution and spray them on the leaves of radishes or cabbage. If you want its effect to be better, you can also add a little trichlorfon to it, which can have a better effect.

When planting, vegetable farmers can use the method of interplanting, in the cabbage, radish field, interplanting peppers, garlic and other spicy vegetables, these vegetables will exude a special strange taste in the growth process, directly make the cabbage worms escape from the vegetable garden from a young age, so that it can play a role in repelling insects.

Pesticide prevention and control, can be sprayed with 1000 times of phosphine, 2000 times of dichlorbuthrin, 2000 times of cyhalothrin for prevention and control, spraying time to 9 11 o'clock in the morning, 3 5 o'clock in the afternoon is appropriate. Generally speaking, there will be fewer insect pests in the month before the radish harvest, and the insect pests are cabbage green insects: the larvae of cabbage butterflies, mainly the leaves.

The larvae of cabbage arterium have a small amount of food before the third instar and poor drug resistance, so the pesticide control should be controlled before the third instar. For the prevention and control of pesticides, 10% of the suspension agent is 1500 times the liquid, or Laixi suspension.

Garlic and silk nuts can be used to control cabbage worms. Take garlic, or loofah each a kilogram, then add an appropriate amount of water, mash it into a paste respectively, and then add 5 kg of water respectively, filter the residue, respectively, used to spray vegetables, so that you can prevent and control insects by hand is also a common method in the past, direct and effective, the key is that the work efficiency is low, if there are more vegetables planted, it is too slow. Then let's have a method of insect control, when there are cabbage green worms on the cabbage radish, catch a part.

When the cabbage moth turns from eggs to green insects, it is also the time when it eats away at the leaves of vegetables, and when it eats carefully when it is a child, it only eats the mesophyll part of the leaves, so we can always see that the leaves only have two skins, in fact, it is eating the mesophyll. Wait for it to be slightly longer and manually captured: cabbage insects generally appear in the morning or evening, and the elderly in our village will go to their own vegetable gardens at this time to manually capture them, catch the larvae or remove the eggs, which is more labor-intensive, and can only be practical in a small area, but effective.

1.Sprinkle plant ash. Grass ash is the rural people use firewood and grass to boil water for cooking, fully burned ashes, its main component is potassium carbonate, it can be sprinkled in the field can be made potassium fertilizer, can also be insecticidal and sterilized, it can be said that kill two birds with one stone, used to deal with cabbage insects The effect is also good, it should be noted that do not sprinkle grass ash in the weather before the wind and rain, so as not to be blown away by the wind and rain.

In addition to dry application, you can also sprinkle plant ash in clean water, stir well, let it stand for two hours, and then spray vegetable leaves with its leachate, the effect is also obvious. 2.Spray with a mixture of paprika and peppercorns.

It is best to use Chaotian pepper with a relatively large degree of spiciness, so that the mixture is numb and spicy, spray it on the radish and cabbage leaves, and you will no longer be afraid of cabbage worms. If possible, mash the garlic and add it to the mixture for better results

The same kind of killing, cabbage green worm treatment mixes the mashed green worm with detergent and sprays it with water. Specifically, we catch the green worms in the cabbage, soak them in water for a day, and wait until the green worms are rotten and deteriorated, with the spoilage liquid, water and washing clothes to spray on the cabbage, which not only protects the environment and has no pollution, but also can effectively prevent and control the cabbage worms, and the cabbage will grow as long as possible, and when the cabbage is ripe, you can eat delicious green cabbage.

You can use pesticides to control, which is the simplest and most effective, you can also use the grass ash produced when you burn the pot in the countryside, and the skill sterilization can also increase soil fertility, and if you have time, you can also catch insects every day.

The cabbage planted has been harmed by some green cabbage insects, and I don't want to sprinkle pesticides, how should I prevent it? At present, the effective control method is spraying drugs, but considering the pesticide residues and people's popularity of organic vegetables, Chinese farmers have given up drug control in order to facilitate vegetable sales, and have used various local soil methods to control cabbage worms. The following will introduce you to several soil methods for the prevention and control of green cabbage insects.

Plant ash insecticidal method.

As the name suggests, plant ash is the ash left behind by burning tree branches, straw, etc., and can be found in every kitchen in rural areas. We can use its alkaline water to spray green vegetables. This method is not only insectic, but also can be absorbed by vegetable leaves as foliar fertilizer.

You can also soak the roots of vegetables with plant ash soaking water, and the eggs in the ground will be burned off when they come into contact with the plant ash. This method can not only inhibit the activity of underground pests, but also improve the self-resistance of vegetables. Plant ash insecticide is a control method worth promoting, which can inhibit the control of various crop diseases and pests.

Orange peel insecticidal method.

Mix a few pieces of orange peel with water and soak them in a container for more than 24 hours, then spray the soaked orange peel liquid on the cabbage to get rid of the aphids that eat the cabbage. Because orange peel contains substances that kill insects, it is harmless to people and animals. It is a new type of high-efficiency, broad-spectrum, non-polluting insecticide.

Pepper water insecticidal method.

Sichuan pepper itself is a natural insecticide. The peculiar smell of Sichuan peppercorns is the natural enemy of most pests. The method is to take an appropriate amount of pepper and soak it in water for 24 hours, filter it and spray it on the green vegetables, which can effectively kill the green vegetable pests that harm the cabbage.

Tobacco and tobacco insecticidal methods.

The method of using tobacco and tobacco to kill insects is also very effective, and the control effect on green vegetable pests is more obvious. The method is the same as that of Sichuan peppercorns. Soak an appropriate amount of shredded tobacco or tobacco in water for 24 hours and spray it on top of the cabbage.

The reason why tobacco leaves can kill insects after soaking in water is that tobacco contains nicotine, which is a harmful ingredient that can kill some small animals and insects.

Soak the roots of the vegetables in water with plant ash, and the eggs in the field will be scorched when they come into contact with the plant ash. This method not only inhibits the activity of underground pests, but also improves the self-resistance of vegetables.

The best thing to do is to spray some garlic juice, which will have a deworming effect and will not contaminate the vegetables.

Use some alkaline water for spraying, which can also be effectively controlled, and can better protect plants.

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.

1. Sprinkle grass and wood ashes. Because the plant ash is alkaline and inedible, sprinkling the plant ash on the vegetable leaves can prevent the cabbage insects from eating the vegetable leaves. 2. Artificial insect catching.

Manual insect catching is a more troublesome method, but it works well; 3. You can mash Chaotian pepper or garlic, add water to filter the juice, and then spray the juice evenly on the leaves of vegetables.

You can mix the mashed cabbage worms with cabbage, and then spray them on top of the crops, so that you can have a dispersal effect, and you can also use green onions for control, garlic can also be used for control, and you can also carry out interplanting at intervals.

At this time, you can choose the method of interplanting, and you can plant garlic or pepper around the cabbage, which is spicy, and then can achieve the effect of killing insects.

You can put some other physical methods, and it is better to put some lights, which can be very good for insect prevention.

I think you can beat garlic into juice and then dilute it fifty times to spray, so that it can also have the effect of killing insects.

I think it's okay to have a few chickens so that the chickens can eat the bugs and there will be no pesticide damage.

In addition to pesticides, there is really no way to stop these insects, unless the insects are stopped at the root and vegetables are developed that are not afraid of such insects.

You can choose a variety of methods to spacing vegetables, you can sprinkle plant ash directly on the leaves, or you can spray it with a liquid made of things that you often use at home.

Catch bugs with your hands. You can pinch all those bugs to death, and that will solve the problem.
