What medicine is used for dry snails in vegetable fields, and what drugs are used to prevent and con

How to treat snails.

1. Pesticide method.

2 kg of 6% Mida (tetraacetaldehyde) snail killing granules, 8% snail kill granules or 10% paraacetaldehyde (snail enemy) granules can be used per mu, accompanied by an appropriate amount of fine soil or fine sand, and evenly sprinkled in the field in the evening.

2. Sprinkle grass and wood ashes.

In the evening, spray the leaves of vegetables with grass and wood ash water, which can play a role in controlling existing snails; Applying ash water to the soil can kill snail eggs. In addition, plant ash is also a good potash fertilizer, killing three birds with one stone.

3. Sprinkle quicklime.

Sprinkle some lime powder around the roots of the cabbage.

In this way, the snail comes out to feed at night, and when it passes, it will be stained with lime and burned to death by the high temperature generated or die of water loss.

However, lime should not be sprinkled too much, otherwise it will affect the soil and is not conducive to the growth of vegetables.

It is also best to do it when the soil is dry, and the soil is more humid and will cause the effect to be poor.

4. Booby trapping vegetable leaves or melon peels.

In the evening, use melon peels, vegetable leaves or weeds (any kind is sufficient), put them aside, and the snails hide under them at night, and the vegetable leaves can be uncovered in the early morning of the next day to kill the snails that are trapped.

Snails refer to the terrestrial species of the class Gastropoda.

All kinds. Including the snail family and the large snail family.

The whole body of the snail includes eyes, mouth, feet, shell, antennae and other parts, and the spiral shell on the back of the body, its shape, color and size are different, and their shells are pagoda-shaped, top-shaped, conical, spherical, pipe-shaped, and so on. Now the white jade snail is bred in China.

Cover large snails, scattered large snails, bright large snails, brown cloud agate snails.

and so on have their own unique shape. The eyes of the snail grow on the back pair of antennae on the head.

Snail shells are generally low-conical in shape, right-handed or left-handed. The head is conspicuous, with 2 pairs of antennae, and the apex of the large 1 pair has eyes. The ventral surface of the head has a mouth with a toothed tongue that can be used to scrape food.

Snails have carapaces, are shaped like small snails, and are diverse in color; The head has four antennae, the head is extended when walking, and the head and tail are retracted into the carapace together when frightened; Snails have saliva on their bodies, which can restrain centipedes and scorpions. In June and July, when it is hot, it hangs under the leaves and rises high until it dies after salivaing.

Snails are the animals with the most teeth, but their teeth are not "three-dimensional teeth". Despite having tens of thousands of teeth, they are unable to chew food. This is because they crush food with a toothed tongue – a ribbon-like structure covered with teeth – so that it can be digested.

Over the course of a lifetime, their tiny teeth slowly wear out and dull and are replaced by new, sharper teeth. Snail excretion is excreted close to the breathing hole, which is called a stomata. It will pass poop on its own body, and eventually leave it on the ground through its gastropods and mucus.

Comprehensive measures can be taken to control snails in vegetable fields. 1. Clean the ditch in time, remove weeds, ensure that the furrow surface is dry, and destroy the snail's habitat and spawning place. 2. Manually kill, pile the half-dried weeds on the vegetable furrow, and kill the snails that are concentrated on it in the morning.

3, sprinkle quicklime, after the surface of the rapeseed soil is dry, sprinkle quicklime around it, 5-10 kg per mu, snails stained with quicklime will lose water and die, the agent control per mu with 6% polyaldehyde carbacarb granules 600-750 grams, evenly sprinkled into the field in the evening.

Snails, slugs, snails.

Prevention and control: Tetraacetaldehyde can be sprinkled before and after evening to prevent snail security.

Scattering quicklime strips is also an effective way to control snails, and sprinkling about five centimeters of quicklime around the farmland can effectively prevent snails from entering the field.

It can also be sprayed before 10 o'clock in the morning or around the evening, and the effect is also good.

What should I do if there are too many vegetable snails growing at home? Teach you to make 2 kinds of insecticides, the effect of snail control is very good.

What to do if celery doesn't go roots?

With the medicine you said, it will not affect the growth of celery.

Prevention and control method 1: Before planting, fully decomposed organic manure should be applied to reduce the burning of roots and seedlings caused by immature manure; In addition, it is necessary to reduce the amount of chemical fertilizers, deepen the soil layer, and reduce the burning of roots and seedlings caused by excessive return of fertilizer next to the fertilizer or direct contact with fertilizer seedlings. 2. Spray regulators and liquid fertilizers, such as foliar spraying of gibberellin, plant power 2003, agricultural vitality, Jintailong top dressing, power pioneer, Luoxiaowang, 518 liquid fertilizer, etc., to reduce herbicide damage and regulate plant growth. 3. Chong Shijia has a source of life or infiltrates Hangui humic acid or root-increasing products, regulates the soil, increases the root system, enhances the stress resistance of vegetables, and improves the growth environment of vegetable roots.

Hello, pro will not rest assured.

1. 600 grams of 10% snail dichloride (polyacetaldehyde) granules can be used and sprinkled on the furrow surface or under the corn bottom. 2. You can also use 30-60 grams of 80% tetraacetaldehyde, spray with water, and when the disaster is serious, you can apply the pesticide again every 10-15 days. 3. Snails will eat the fine buds and young leaves of crops, and eat various vegetables, weeds and melon peels.

4. Snails will parasitize on citrus fruits, gnawing on leaves, branch cortex and fruits.

1. What medicine can get rid of snails in cornfields

1. Remove the agent of the corn field snail.

1) Use 600 grams of 10% snail dichloride (polyacetaldehyde) granules per mu, spray the agent evenly on the furrow surface, or sprinkle the particles on the ground below the corn.

2) 30-60 grams of 80% tetraacetaldehyde can also be sprayed with water, and in the seriously damaged plots, it can be sprayed again at intervals of 10-15 days.

2. Symptoms of snails harming corn.

1) When snails are infested in corn fields, strip-like cracks will appear on the leaves of corn. Cracks in leaves that have been bitten by snails often leave only a layer of transparent epidermis.

2) When the snail damage is serious, it will lead to the lack of seedlings and the distortion of the leaves of the corn, which will affect the photosynthesis.

3) The rate of snail damage to corn fields is 10-15%, and the rate of damage in serious fields is more than 50%, which poses a great threat to the normal growth of corn.

Second, the hazards of snails

1. Snails are one of the most common mollusks on land, mainly feeding on plants and preferring to nibble on the fine buds and young leaves of crops.

2. Snails have a wide range of diets, staple food of various vegetables, weeds and melon peels, and will also gnaw on the leaves, stems, buds, flowers, juicy fruits of crops and various grass barley feed, juicy feed, bran feed, cake feed, etc., so wild snails have greater harm to crops.

3. Snails often parasitize on citrus fruit trees, citrus leaves are often eaten into notches, and the branch cortex of fruit trees is often eaten, and snails will gnaw on citrus fruits, resulting in the formation of pits.

4. Snails can also parasitize on plants such as forest seedlings, vegetables and flowers.

5. Snails will harm soybeans, generally in the soybean seedling stage, which will cause damage to leaves and stems, delay the emergence of stiff seedlings, decline in seedling rate, and eat up all the soybean seedlings in serious cases.

Summary. Hello, the control of wheat snails is sprinkled with tetraacetaldehyde granules<> how to treat wheat snails?

Hello, wheat snail control using tetraacetaldehyde granules for sprinkling<> per mu with 6% granules 500 grams of high slow letter, evenly sprinkled, Qi wheel or mixed fine sand sprinkled, which noisy Fushou snails, snails, slugs are easy to contact the agent, can achieve the effect of seedling preservation. <>

It can also be sprayed with 40-50 grams of 80% wettable powder per mu and mixed with water. <> precautions for dressing up: 1

In case of low temperature (below) or high temperature (above 35), the snail activity is weak, which affects the control effect. 2.Do not practice the forest chain in the ground after application, if it rains heavily, the pesticide particles are washed into the water by the rain, which will also affect the efficacy of the medicine and need to be supplemented.

3.After using this pesticide, do not trample on the field. After taking the drug, wash your hands and contact with soap and water**.

Prevention and control methods: 1. Sprinkle plant ash. In the evening, sprinkle dry and pure plant ash on the stems and leaves of melons and vegetables, if the stems and leaves are dry, you can spray some water first, so that the leaves are moist and then sprinkled with a ruler, and the snail will not climb on the stems and leaves to bite the stems and leaves.

2. Sprinkle lime powder. After heavy rain, a layer of lime powder is sprinkled around the crop, about 3 5 mm thick and 40 50 cm wide.

3. Remove weeds, thoroughly clean up the places where snails can inhabit such as stones and debris on the ground, and eliminate snail breeding grounds. Cultivating soil can kill some snails and reduce the density of snails.

Fourth, vegetable leaf trapping. In the evening, set up a number of large vegetable leaves or fresh grass piles in the field, and the snails hide under them at night, and the vegetable leaves can be uncovered in the early morning of the next day, and the snails that are trapped.

5. Manual capture. Snails crawl extremely slowly and are easy to catch. In the early morning or on rainy days, it is easy to kill a large number of snails on the soil surface and plants.

6. Chemical control. Generally, 1-1 5kg of 8% snail kill is used per mu, mixed with l0-20kg of sieved fine soil, and the soil surface is sprinkled in the evening on a sunny day. Or use 6 Mida granules to mix dry fine sand according to 1g m2 and evenly sprinkle it in the furrow for control.

Growing and developing vegetables and melons and fruits, it is easy to be harmed by snails, mainly biting stems and leaves, melon flesh, pulp, causing rot, in the evening, early morning and after the rain is the most serious, because the snail is a crawling pest, it will run away after biting, it is difficult to use drugs to prevent and control, and day and night, many times of medication will pollute vegetables and melons and fruits, the following methods can be taken to prevent and control:

1. Sprinkle plant ash in the evening with dry and pure plant ash sprinkled on the stems and leaves of melons and vegetables, if the stems and leaves are dry, you can spray some water first, so that the leaves are moist and then sprinkled, snails will not climb up the stems and leaves to bite the stems and leaves.

2. Sprinkle lime powder After heavy rain, sprinkle a layer of lime powder around the trunk of the fruit tree, about 3 5 mm thick and 40 50 cm wide.

3. Spray tea bran liquid with 1 kg of tea bran, process it into powder, add 10 15 kg of water, stir fully and mix evenly, soak for 8 12 hours, take the clarification solution, when it is found that there are snails on the stems and leaves of vegetables and melon flesh and pulp, when the flesh is harmed, spray on the stems and leaves or the crown of the tree, you can kill the snail.

The above prevention and control methods do not have any toxic residues, will not pollute vegetables and fruits, spray or sprinkle on the same day, can be harvested on the same day, and do not endanger human health.
