The cabbage insects on the radish and cabbage are rampant and I don t want to use pesticides, what i

When farmers grow vegetables, the most annoying thing is that the vegetables they grow have pests and diseases! Even if you spray some pesticides, you can quickly discard them. But sometimes farmers often don't want to use pesticides because once they do, there is a risk that the pesticides will be left behind in the vegetables.

As a result, many vegetable dishes grown in rural areas are not very good, and some wormholes are often found in these dishes. The dishes of the better vegetables in the market basically use various pesticides. After all, in the process of growing vegetable farmers, there are bound to be various pests.

One might say that by setting up special planting sheds, pests can be avoided as long as insects are prevented from entering the planting sheds. In fact, there are many pests, which all dig out of the soil and harm growing vegetables.

So, do farmers not use pesticides to avoid the harm of pests to vegetables? In fact, long ago, before pesticides came out, we had many local ways to control pests. However, these soil methods are certainly not as effective as pesticides compared to pesticides.

For example, a farmer or a turnip in cabbage has cabbage worms, and the farmer does not want to use pesticides, the following earthmoving methods can be used for prevention and control.

First, farmers can use rural ash to control cabbage worms. Despite the fact that burning wood for cooking is now banned in many places, farmers want to get some plant ash, but it is relatively easy. Farmers collect plant ash, which is then mixed with water.

The mixing ratio depends on the situation. Usually, water is 1 to 3 times more than plant ash. If the pest is more severe, add less water.

Soak the plant ash in water for more than 12 hours, then filter out the soaking solution of the plant ash and spray it on the vegetable leaves of radish or cabbage. If you want it to work better, you can also add a little trichlorfon to it for even better results.

Then the farmer can also use the garlic, mash it and mix it with water. The general mixing ratio is one pound of garlic and two pounds of water. Soak it for more than 12 hours before straining out the garlic mixture.

This mixture of garlic and water is then sprayed on the leaves of radish or cabbage. Although the effect is not as good as that of plant ash mixtures, it is also a relatively good method in the soil method.

Farmers can also use biological control methods to remove radish or cabbage cabbage greenworms from the ground. If there are cabbage worms in the vegetable field, the farmer can put the chicken in the vegetable field. Although chickens will also eat some vegetable leaves, if there are worms, chickens will choose to eat the worms first.

However, it is better to have someone to guard the vegetable patch. When you feel that the chickens are starting to eat a lot of vegetable leaves, you need to drive the chickens out of the vegetable patch. In addition, if the vegetable patch can be surrounded by a net, then the farmer can take advantage of the frog's characteristics to eat insects to control radish or cabbage cabbage greenworms in the ground.

And frogs can only eat cabbage worms or other pests, not vegetable leaves.

Cucumber vine spray: If you happen to plant cucumbers, you can add a little water to mash the fresh cucumber vines from the whole branch, filter out the residue, and spray with 3 times the water with the juice, which can also control cabbage worms and vegetable borers, and the control effect is 95%.

Artificial insect control: It can manually catch or pinch off the pupa and larvae of cabbage green worms on vegetable leaves. Remove residues such as branches and leaves from the potting soil in time after harvesting.

Pepper water spray: use kilograms of fresh red pepper (the spicier the better), mash and add 5 kilograms of water, heat and cook for 1 hour, take its filtrate and spray, which can control cabbage worms, vegetable borers, etc.

In this case, you can use plant ash to dilute it with water and spray it on top of the leaves. Then after the cabbage worm eats the vegetable leaves sprayed with the dilution of plant ash, the worm will die.

This small number can be removed by hand, after all, green insects can be seen, if there are more, you can use plant ash mixed with water to kill insects, the effect is also good.

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.

A variety of vegetable spacing methods are used. When the cabbage worm is young, it often wriggles on the vegetable leaves, and keeps gnawing on the tender leaves of vegetables, as the cabbage worms grow up, they eat more and more, and the vegetable leaves are eaten into many residues, and some directly bite the leaf surface into a big hole, and the disabled area of the vegetable leaves is getting larger and larger, and some of the leaves become net-like, which seriously affects the growth of vegetables, even if such vegetables grow up, they cannot be sold. Then, 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 deworming effect.

Catching 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 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. <>

Hang nets in spring to prevent insects. Spring and autumn is the season when cabbage worms often appear, the size of cabbage worms from small to large may appear, generally the eggs become worms and then slowly wriggle to the leaves of vegetables, and at the end of autumn, they will crawl to the hidden place near the vegetables to form a pupa butterfly to lay eggs. Therefore, hanging a 2 mm mesh insect net in early spring can effectively prevent cabbage insects from crawling in and out, which is more conducive to the treatment of cabbage worms.

Use natural predators: Spiders and ladybugs are more common in rural areas, and we can put these in the vegetable garden, which can eat some of the larvae, which can reduce the damage of cabbage worms.

The above are several methods commonly used by our farmers, all of which use pure natural plants and natural enemies to trap and kill, and their effects are remarkable. However, these can only be used in the early stage, when the harm is less severe. If the scope is too large, I recommend that the drug be used to prevent and control it, so as not to delay production.

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.

To kill cabbage insects on radish cabbage, biological agents such as Bacillus brevis, Bacillus thuringiensis, azadirachtin and karyotype polyhedrovirus can be selected.

Expand your knowledge: How is radish cultivation seeded and managed?

First, select and prepare the land.

Radish varieties should be selected with strong disease resistance, high yield, good appearance, and suitable for local market sales. The fleshy roots of radish are relatively developed, so it is suitable for planting in loose and fertile areas, strong water and fertilizer retention capacity, and convenient drainage and irrigation.

A few days before sowing, try to plough the soil and dry it, and apply about 3,000 kg of decomposed organic fertilizer, about 15 kg of urea, 30-40 kg of superphosphate, and about 10 kg of potassium sulfate as base fertilizer. Then the rake is finely leveled, leaving no large clods of soil, so as not to affect the emergence of seedlings.

2. Sowing and management.

1. Radish should not be planted with stubble, and should also be avoided with cruciferous vegetables to avoid pests and diseases, because it will affect the quality and quality of radish.

2. The early growth of radish is mainly based on basal fertilizer, if there are weak seedlings after the seedlings are full and the growth is not good, the fast-acting nitrogen fertilizer can be applied in time. Try not to chase fast-acting fertilizer after the seedlings are set, so as not to grow the seedlings and affect the swelling of fleshy roots. Although the water requirement of the seedling stage is small, it is necessary to ensure that the soil is moist and not dry.

When the roots begin to swell, about 10 kg of urea per mu is applied, and phosphorus and potassium fertilizers are added at the same time, such as the polymerization of potassium dihydrogen phosphate by soil chefs.

3. When the root of radish is in peak growth period, the amount of water supply should be increased, and the soil moisture should be kept at about 70-80%. to prevent hollow turnips. During this period, about 10 kg of urea can be applied with water during watering, and micro-fertilizer supplemented with soil trace elements can be used to ensure the quality of the fleshy roots of radish.
