Is there a way to get rid of pests on vegetables without pesticides?

Vegetables with a special smell can be chosen to be planted, which will reduce pests, such as leeks, garlic, onions, lettuce, celery, and many more. You can also use insect nets to keep pests out of the shed, or you can use insecticidal lamps to trap them.

There is no way, because the vitality of pests is very tenacious, and they will not be completely eliminated without pesticides.

Use black lights or frequency vibration insecticidal lamps for booby-trapping, and place a black light or frequency vibration insecticidal lamp at intervals in the field to trap pests at night. It can effectively control many phototaxis pests such as Lepidoptera.

There is no way to remove the pests on the vegetables without pesticides, so we must use pesticides when there are pests.

Avoid and trap insects in the vent of the shed set up butter board trapping, the method is to use waste fiberboard, planted into 1 meter long strip, painted yellow with paint, and then coated with a layer of sticky oil, placed between the rows can be the same height as the plant, when the whitefly sticks to the board surface, need to be recoated with sticky oil in time.

Insecticides should not be sprayed on vegetables to kill insects. Pesticides are toxic and harmful to the elderly or children. Insecticides are mainly used to control agricultural pests and urban health pests, with a long history of use, large dosage and many varieties.

According to **, it can be divided into two categories: bio-derived pesticides and chemically synthesized pesticides.

Pesticide Category:

1. Biological pesticides: Biological pesticides have special control effects on pests, and are extremely safe, with high efficiency, low toxicity, no residue, and drug resistance.

Slow and other characteristics. Such as the bacterial insecticide BT (Bacillus thuringiensis.

microbial insecticides), avermectin.

Niacinidine plant insecticides; fungal insecticides (Beauveria bassiana); Insect viruses, insecticides, and insect pheromones (e.g., sexual attractants).

2. Plant-derived pesticides of modern concepts: plant extracts (such as azadirachtin and sensendantin) that have specific effects on pests such as refusing food, repelling, hindering development, and interfering with reproduction.

3. Insect growth regulators: they can play a controlling role by hindering the peeling of pests and interfering with development, which is harmless to humans and higher animals, has little impact on natural enemies, and is safe for the environment.

4. High-efficiency, fast-acting, low-residue agents: such as pyrethroids, especially some new varieties, such as tetrabromothhrin to control vegetable pests, the dilution concentration can reach 8000 10000 times, and low residue, short safety interval.

5. New insecticides: This type of insecticide has a unique structure and mechanism of action, and is highly effective against harmful pests, such as imidacloprid.

It has been widely used. Another example is Actay.

It is a new generation of strong systemic insecticide, low toxicity and high efficiency insecticide, which has a special effect on the control of whitefly, and the dilution concentration is up to 5000 times.

These pests are a necessary guarantee for high yields of green vegetables. In particular, cabbage, radish, cabbage and other large green leafy vegetables are the favorite food of cabbage insects, and if they are not stopped in time, cabbage insects can even gnaw the whole vegetable leaves. At present, the most commonly used control method is to spray the drug, taking into account the 70 centimeters, erect and branched, the flowering period is April, and the fruiting period is May.

Green cabbage is native to Asia and is currently widely cultivated in the north and south of China, mainly in the Yangtze River Basin. The young leaves of green vegetables are edible and are also a favorite food for pests.

<> then what other way to eat cabbage besides using pesticides, but every year my mother only starts to plant it after winter, and she can usually eat cabbage or cabbage from her garden in winter or early spring. I don't understand why other seasons are not suitable for growing cabbage or cabbage. My mother said no, saying that only in the cold temperatures of winter can green vegetables taste tender and juicy, and are an ideal ingredient for many pests.

It is also a group with a high incidence of insects, how to kill and expel insects without using pesticides, in fact, there are many soil methods in rural areas that can be done, some plants themselves contain toxins, and the production of soil pesticides is the key to the current life, diet, everyone advocates green pollution-free and pollution-free food, we have this idea, there is this awareness, in fact, it is still good. However, if you want to kill the vegetables without pesticides when you plant a large area, it is almost the first thing to choose a variety of vegetables that have fewer insects.

For example, lettuce, cabbage, spinach, penny, summer water spinach, kraft cabbage and other green vegetables, rarely attract insects to eat, these vegetables are just when the seedlings emerge, aphids eat quickly, spray pesticides appropriately, and will not use drugs later, and there are few insects. Vegetables, cauliflower and other vegetables, if no pesticides are used during planting, it will not take long for the leaves of vegetables to be covered with many insect eyes, now many people advocate green planting, no pesticides and no chemical fertilizers, so what should be done to make vegetables not grow insects under the premise of not using pesticides?

We should spray some vinegar because vinegar is also effective in preventing pests and diseases, and it can also increase the yield of green vegetables.

According to the survey, among the birds inhabiting in China, most of the gray magpies and woodpeckers are beneficial birds that prey on pests, which play a huge role in controlling the harm of fruit tree pests. In or around the orchard, insects can be treated by hanging artificial nests to protect and attract beneficial birds. It can also take advantage of the habit of chickens and ducks pecking at insects such as green worms, caterpillars, and beetles, and carry out free-range breeding in orchards to control the occurrence of insect pests.

You can put some plant ash on top of the greens, and the plant ash also has the effect of preventing insects, which will automatically keep the insects away from the greens.
