What are the effects of pesticides on earthworms in the soil

According to surveys, the use of pesticides, especially highly toxic pesticides, can cause earthworms.

Small quantities. In the general organophosphorus pesticides, glutathion, diazinon, pine borer, marathon, trichlorfon, etc., under normal dosage conditions, there is no obvious toxic effect on earthworms, but there are some such as chlordane, heptachlor, dichlorvos, methyl bromide, chloropicrin, simazine, carbaryl, carbofuran, aldicarb, copper sulfate.

3911 and so on are very toxic to earthworms. It is best not to use these pesticides for earthworms in field farming. Some chemical fertilizers such as ammonium sulfate, ammonium bicarbonate, potassium nitrate, ammonia, etc., also have great damage to earthworms at a certain concentration.

For example, ammonia water is applied 25 times that of water according to the common method of agriculture, once the earthworm comes into contact with this 4% ammonia solution.

Water dies in tens of seconds, or in a few minutes. Therefore, if it is a farmland where earthworms are raised, organic fertilizer or urea should be applied as much as possible.

The urea concentration is less than 1%, which not only does not poison earthworms, but can also be used as a nitrogen source to promote the growth and development of earthworms.

Pesticides can have an impact on earthworms in controlling the number of pests in the soil, protecting earthworm habitat and improving soil fertility.

First, the use of pesticides can help control the number of pests in the soil. When there are too many pests, they can destroy crops and affect their growth.

Secondly, pesticides can also protect the habitat of earthworms. Earthworms need a moist, breathable environment to survive, but some pests can destroy the earthworm's habitat and make it impossible for them to survive.

However, it is worth noting that some pesticides may be toxic to earthworms, such as chlordane, heptachlor, dichlorvos among organophosphorus pesticides. If these pesticides are used, they may have a negative impact on earthworm populations. In addition, some chemical fertilizers such as ammonium sulfate, ammonium bicarbonate, potassium nitrate, ammonia, etc. may also kill earthworms.

Therefore, these fertilizers or pesticides should be used as little as possible in the farmland where earthworms are farmed.

At the same time, pesticides can also help improve soil fertility. Because earthworms are very important organisms in the soil, they can help improve soil fertility. Earthworms swallow organic matter in the soil, digest it and excrete it into earthworm droppings.

This earthworm manure is rich in nutrients that can help improve soil fertility.

Overall, while pesticides help protect and improve the soil, they also need to take into account the impact on soil organisms such as earthworms to maintain the balance and health of the soil ecology.

Insecticides are toxic, earthworms are very sensitive to them, and earthworms will flee when they encounter insecticides.

If there are earthworms in the pot, you can choose to go to the flower shop to buy some pesticide powder and sprinkle it on the surface of the soil, you can choose pesticides such as trichlorfon and sprinkle it on the surface of the soil, and trichlorfon can kill the earthworms.

You can also choose to use tea saponin, which is used in emulsifiable pesticide, which has the advantage of good control effect, rain resistance and long-lasting effect. Moreover, the biological hormones contained in tea saponins are also good for the plant itself.

If there are earthworms in the pot, the use of tea saponin can not only effectively kill, but also will not pollute the soil, which is conducive to protecting the environment. If earthworms appear in the pot, it is better to get rid of them or eliminate them as soon as possible. If it is not very serious, try not to choose medication.

The earthworms can be killed with trichlorfon powder, just sprinkle the agent on the surface of the soil, stir well with the soil, and water can play a role. In addition, the most direct way to kill an earthworm is to soak it in water, because the earthworm is afraid of water, as long as it is watered a lot, let the earthworm in the soil be soaked in water overnight, and it will crawl out of the soil on its own.

Although earthworms have the effect of loosening the soil, they will also affect the growth of crops and even destroy the potato pieces under the soil; It can be killed without pesticides, sprinkled with lime powder into the soil or watered with lime water.

In fact, earthworms are not considered pests, but if the number of earthworms is too large, you can use diazinon and ground insect elimination, where earthworms are concentrated, and mix diluted dianon into the soil. In addition, the use of pesticides must not be abused, pesticides are not omnipotent, too many pesticides are harmful.

How to use: 1. The lawn is sprayed with 80-100 kg of water per 250 grams of water for 2-3 days after the lawn grass is mowed, and the spraying area is 330 square meters.

2. The use of nursery land can be appropriately sprayed on the surface according to the dosage of 500 grams per mu mixed with water, and then watered;

3. Seedlings with a diameter at breast height of less than 10 cm can be opened at the root of a 40-50 cm annular soil ditch, with a depth of 5-10 cm, this product is diluted 200-300 times the liquid for spraying, each bottle can be used with 10-12 trees, and then watered and covered with soil; For those with a diameter of 10-15 cm, a soil ditch of 60-80 cm is opened at the root of the tree, and 6-8 trees can be sprayed per bottle; For large trees with a diameter of more than 15 cm, a 100-120 cm soil trench should be opened, and 2-4 trees should be sprayed per bottle.

Earthworms are beneficial insects, there is no need to kill them, earthworms can loosen the soil. It can make the soil softer and good for plants. Earthworms can be killed with insect meal.

Zinc sulfon is specialized in killing underground pests, and the effect of up to 50 to 60 days of efficacy, insecticidal widespread, direct sunlight decomposition, high efficiency and low toxicity.

There are a lot of earthworms and bloodworms in the soil, which is a good thing, which is enough to show that the land is very fertile and less polluted by chemical fertilizers, which not only does not have any impact on the crops, but also greatly benefits the crops. Earthworms and bloodworms suck on decaying and spoiled things, and feces are the best organic compounds that crops can easily absorb. Earthworms and bloodworms will penetrate and drill holes, so that the land has favorable conditions for ventilation and water leakage, and the roots of crops absorb nutrients quickly, in abundance and uniformly.

The movement of earthworms homogenizes the soil with a huge disparity between the rich and the poor, and crops grow in a balanced manner. The earthworms in the field mostly live in the roots of plants, and suck the harmful substances produced by the roots of plants, and the manure released is organic fertilizer, which is a good nutrient for crops.

Earthworms and bloodworms can loosen land. There are many earthworms and bloodworms in the soil, which means that the soil is fertile, and there are many earthworms and bloodworms, and the constant movement in the soil also has a great effect on reducing the problem of soil compaction. Earthworms and bloodworms only eat rotten leaves, rotten leaves, animal feces, etc., and do not eat animals and plants that have not been fermented and rotted, because earthworms have no teeth and cannot bite.

Therefore, if you are growing vegetables, you can regularly pile up some rotten vegetable leaves and peels on the surface of the soil, and earthworms and bloodworms will not gnaw on the roots of vegetables if they have to eat.

Earthworms and bloodworms are beneficial insects, which can not only loosen the soil, but also excrete manure is a very good organic fertilizer, which is very helpful for the growth of vegetables, and we farmers need to make good use of it. The movement of earthworms and bloodworms in the soil can make the soil permeable, and the excrement of earthworms and bloodworms is a good organic fertilizer for plant growth, which has a great effect on improving the quality of soil and the growth of crops. The movement of earthworms and bloodworms in the soil can also improve the soil structure, and the acidic soil and alkaline soil are transformed into neutral soil, which is more suitable for the growth of crops.

The movement of earthworms and bloodworms in the soil can also improve the soil structure, and the acidic soil and alkaline soil are transformed into neutral soil, which is more suitable for the growth of crops.

Therefore, earthworms and bloodworms not only do not affect the growth of crops, but also have the effect of enriching the soil and improving the quality of the soil. Earthworms and bloodworms are also good feed for chickens, ducks, fish, soft-shelled turtles, etc., and can also be used as raw materials for pharmaceuticals and bait for fishing.

Earthworms can also degrade soil pollution caused by sewage irrigation, the sedimentation of polluted dust, and the abuse of pesticides and fertilizers, while earthworms can absorb and decompose pollutants in the habitat, such as organic pesticides, heavy metals, radioactive substances, etc. Some factories abroad have built tall vermicompost air purification towers, through which toxic gases and foul-smelling gases can be detoxified and deodorized. In the United States, research is underway to use earthworms to purify municipal sewage so that it becomes clean water that flows back into rivers.

In this way, the soil can become more fertile, and at the same time, it can also achieve the effect of loosening the soil, and finally it can also improve the yield of crops, and it is also a very good organism, and the soil can also be improved, and the soil will be very soft, which can also reduce the workload of farmers.

It can loosen the soil, make the soil more nutritious, improve the soil environment, make the soil more drainable, and let the plants grow better.

It can make the soil more fertile and reduce some pollution, so the soil should have a lot of organic compounds, which is more suitable for plant growth and can make the nutrients more balanced.
