Can vegetable lettuce bruises be cured without pesticides? What are the solutions?

It is also possible to apply no pesticides. Solution:1

The waste of flue-cured tobacco or waste tobacco leaves is used to spray vegetables after soaking in water, which can prevent the breeding of cabbage insects, aphids and other insects. 2.Sprinkled quicklime in the soil can effectively kill insect eggs and germs, and can also prevent vegetable rhizobia.

3.Sprinkle vegetables with stove ash, which is also plant ash, which can not only prevent insects, but also increase the nutrients of vegetables, and is usually used in the seedling stage. 4.

Sprinkle with sulfur powder. Before planting vegetables, scatter them in the ground to prevent insects from entering and laying eggs. 5.

Artemisia annua has a very strong taste, after picking, it can be placed in a pit or a container and soaked in water, and used to water vegetables after two weeks.

Yes, this kind of green bug can also be removed by some methods, it is not necessary to kill it completely, such as using some high-intensity water flow, washing the bug away or taking some lime powder, you can remove them.

Yes. Put it in a bottle with brown sugar dissolved water, 1 bottle every 2 meters, bury half of the bottle in the soil, open the bottle mouth, and the insects smell the sweetness and enter the bottle. Plants such as flue-cured tobacco stalks, soil tobacco stalks, Sophora sophora roots, Masan leaves, neem seeds, etc., are sprayed with soaked liquid to kill insects, and the effect is better, but it is more troublesome when soaking the liquid medicine, and it is not convenient to use pesticides now.

The planting area is not too large, about one acre of land, from the beginning of the seedlings began to eat, until the uneaten ones were dug out and eaten garlic, from planting to harvesting there are almost no obvious insects. It's the same with chili peppers, which are very easy to manage and don't attract bugs.

The methods that can repel insects without pesticides are: loofah insect treatment, garlic insect treatment, cucumber vine insect treatment, and insect treatment method.

1. Loofah insect treatment method:

Harvest an appropriate amount of fresh loofah, then put it in a container and pour a small amount of water, mash it, and filter it to get the original solution. Mix the stock solution and water according to the ratio of 12, then add an appropriate amount of soapy water, shake well and spray.

2. Garlic insect treatment method:

Prepare 1 kg of garlic, then put it in a container and pour an appropriate amount of water, mash it into a puree, then pour 5 kg of water, filter the residue and spray it, which can not only control cabbage insects, but also treat aphids and other pests.

3. Cucumber vine insect control method:

Prepare 1 kg of fresh cucumber vines, then put them in a container and pour an appropriate amount of water, mash them to remove the slag, and drain the water to get the original solution. Each kilogram of stock solution can be mixed with 5 kg of water, and it can be sprayed after mixing.

4. Insect treatment method:

After the occurrence of cabbage worms, catch them in time, collect about 100 grams and mash them, then pour 400 grams of water and soak them for 1 day to let them rot, then filter the original solution, mix 50 kg of water and add 50 grams of laundry detergent, spray on Chinese cabbage to control cabbage.

Popular science of small greens:

Small cabbage is also known as small cabbage, also known as non-balling cabbage, greens, rape. Native to China, it is distributed in all parts of the north and south, and is widely cultivated in China. Brassicaceae spp.

Chinese cabbage is a mustard cultivated plant, the stems and leaves are edible, one or two annual herbaceous plants, often cultivated annually. The plants are shorter, with shallow roots and well-developed fibrous roots.

1. You can raise chickens in the vegetable field and eat the insects, 2. You can cover the vegetables with a wire net, and 3. Put a fluorescent lamp to attract insects, these insect control methods are very effective, so that the vegetables can grow well.

The first method is that all these greens can be transplanted into the greenhouse for planting, the second method is that you should maintain sufficient sunlight every day, the third method is to increase the distance of planting, try to stay away from some, the fourth method is to water more, and the fifth method is to fertilize more when planting, so that there will be no small insects on the surface.

Insects can be exterminated in a physical way, such as setting up an insect-proof net outside the circle, and then you can also place a fluorescent lamp next to the vegetable garden, and then put a large basin next to it, and then you can also choose to catch insects manually.

When growing green vegetables, especially oilseed rape, cauliflower, and other vegetables, it is easy to breed insects. If no pesticides are used during the cultivation process, the leaves of the vegetables will soon be covered by the eyes of many insects. Nowadays, many people advocate green planting, no pesticides, no chemical fertilizers.

So, how do you keep vegetables free of insects without using pesticides? Vegetables grown are prone to insects and can be eliminated without the use of pesticides.

Method 1: Reasonable planting

Some vegetables attract insects easily, but some rarely attract insects, such as peppers and garlic vegetables. For example, in a piece of land, vegetables that attract insects are planted in the middle. Chili peppers and garlic do not attract insects easily. Vegetables grown on both sides can also reduce the occurrence of pests.

Method 2: Capture manually

Bugs about green vegetables can quickly become serious. Many of the causes of severe insect infestations are due to not being properly treated. Therefore, when insects have just occurred, they can be exterminated by artificial capture.

When I was growing vegetables and vegetables that attract insects, my grandma caught them every morning when the sun wasn't shining. I heard my grandmother say that when the sun comes out, the weather gets hot, the insects crawl to the ground, and it's only cool in the morning. When I came out looking for food, everyone was able to catch insects in the morning dew.

Method 3: Spray tobacco leaf water and pepper water

After planting insects on green vegetables, tobacco leaves can be soaked in water, chopped peppers can be soaked in water, and the insects can be expelled. Worms like to eat green vegetables because they don't have other strange tastes. Water soaked in tobacco and chili peppers has a pungent and unpleasant taste.

After spraying on the leaves of vegetables, there will be an unpleasant smell on the leaves, which insects will smell. This taste will not be eaten with vegetables anymore.

Method 4: Spotlight

If possible, it's best to use an insect trap to catch pests, especially for large vegetable growers. However, it is impractical for farmers who only grow vegetables on a small scale. Therefore, the use of trapping light to capture pests depends on the actual situation.

We can use biological control methods to deal with these insects that are harmful to green vegetables.

There are two ways to treat insects, one is through companion plants, and the other is through the use of natural materials.

1. Associated plant method: intercropping and planting of two plants can achieve the effect of insect control. For example: intercropping of green peppers and garlic, intercropping of tomatoes and cabbage, intercropping of shallots and carrots, etc., all of which can have the effect of repelling insects.

Second, the use of natural materials to treat insects:

1. Treat insects with ash liquor. 10 kg of plant ash mixed with 50 kg of water, soaked for 24 hours, and sprayed with filtrate can effectively control aphids and yellow insects.

2. Brown sugar solution to prevent and treat diseases. 300 grams of brown sugar dissolved in 500 ml of water, 10 grams of white-coated yeast were added, placed in a greenhouse or greenhouse, stirred once a day, fermented for 15 to 20 days, until a white film layer appeared on its surface. Then add 100 grams of rice vinegar and shochu to this fermentation broth, and 100 kilograms of water.

It is a good medicine for the prevention and control of cucumber bacterial spot disease and gray mold.

3. Urine lotion mixture to treat vegetable aphids. Washing powder, urea, water according to the ratio of 1 4 400 to make a mixture, can control vegetable aphid, insecticidal rate of more than 90.

4. Tie grass to the trunk to remove insects. Untying the grass and burning it intensively can reduce the overwintering base of pests and get twice the result with half the effort.

5. Plywood painting gathers and captures micro pests. Apply orange-yellow paint on both sides of the larger plywood, and then apply a layer of engine oil and butter mixed oil after drying, and distribute it in the orchard or vegetable garden, where pests such as aphids, whiteflies, and American spotted loon flies will fall into the net. After a week, change the paint and mix it better.

Try using physical or biological insect control.

Remove weeds, residual branches and dead leaves in the field, and eliminate the growth space of pupal cocoons. After autumn, weeds and dead leaves are removed from the field to eliminate overwintering adults. In early spring, when weeds grow, they should also be removed in time so that the overwintering adults have no food**.

In fact, you can apply high heat to the greens, so that the insects can be killed.

Remove weeds and dead leaves from the field, plant vegetables in season, and rotate food.

I haven't grown crops, so I don't know how this thing is.

If you don't want to use pesticides, wash them with water before eating.

Greenhouse culture can be used, so that the insect infestation can be effectively mitigated.

Some of the grass and trees can be planted with greens, or the method of manual cleaning can be adopted.

This may not be available at the moment, but it should be fine to wash carefully before eating.
