What to do if there are snails in growing vegetables, and what to do if snails eat vegetable seedlin

1. Soil treatment.

Try not to go to the creek to get soil, which is a favorite spot for snails because of its proximity to water. It is best to spread out the soil and expose it to the sun for five or six days, using ultraviolet rays and high temperatures, which can burn most of the pests inside. If you want to be faster, it is recommended to boil a pot of boiling water to blanch the soil before using it to grow vegetables.

This method is suitable for those vegetable gardens that have not been harmed by snails, if there are already snails, the following method can only be used.

2. Grass 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, and the snails will not climb up the stems and leaves to bite the stems and leaves.

3. Quicklime.

When the soil is dry, sprinkle a layer of quicklime around the vegetable, about 3 5 mm thick and 40 50 cm wide. Remember to remove excess quicklime afterwards to avoid accidentally injuring your vegetables with too much quicklime.

4. Weeding frequently.

Frequent removal of weeds and thorough removal of snail habitat areas such as rocks and debris on the ground can reduce humidity, reduce snail hiding places, and worsen snail habitats.

5. Turn the soil frequently.

Turn over the soil when you have nothing to do, especially in late spring and early summer, so that the snails and egg masses are exposed to the soil surface, so that they die from exposure to the sun. Ploughing in winter and spring when the ground is cold and frozen can make some adult snails, young snails, and eggs exposed to the ground and be frozen to death or pecked by natural enemies.

6. Entrapment. Taking advantage of the characteristics of snails, large vegetable leaves or fresh grass piles are piled up outside the planting field for trapping (mixed with certain pesticides is more effective), and then the snail dwelling is intensively treated.

It turns out that beer really kills snails, but there are certain premises! What should I do if I encounter snails when planting flowers and vegetables? Teach you a trick without medicine, easy to eliminate!

1. Sprinkle grass ash in the evening, spray grass and wood ash water on vegetable leaves, which can play a role in preventing and controlling existing snails; Applying ash water to the soil can kill snail eggs (not required for hydroponics). In addition, plant ash is also a good potash fertilizer.

2. When the area of quicklime is small, sprinkle some lime powder around the vegetable root or vegetable garden, so that the snail comes out to feed at night, and when it passes, it will be stained with lime and burned to death or water loss by the high temperature generated. When the area is larger, sprinkle a quicklime belt about 10 centimeters wide on the edge of the ditch and the ground, and use 5 kg of quicklime per mu to kill the snails that cross the lime belt.

3. Vegetable leaves or melon peels or fried wheat bran booby trapping in the evening with vegetable leaves and melon peels can be combined with some fried wheat bran, put them aside, and uncover the vegetable leaves in the early morning the next day, and kill the snails that are trapped.

4. Manually catching snails crawls slowly, easy to identify, especially when hydroponic planting, there are fewer places for snails to hide, especially in greenhouses, and it is very easy to catch snails by hand. Soil culture is more troublesome, but before sunset, leaves, weeds, vegetable leaves, etc. are piled up in the field, and one pile is placed every 3 5 meters, and the grass pile is opened before dawn to concentrate on catching.

Snails are ground-crawling gastropod mollusks that generally reproduce for 1 to 3 generations a year, and reproduce quickly during the season of high humidity and high temperature. The peak of activity is from mid-May to early October every year, and eggs are laid under grass roots, soil crevices, dead leaves or rocks in April and May, and each adult can lay 50 to 300 eggs. Snail activity is at its peak from June to September, and it begins to decrease until late October.

The control of snails usually involves a series of integrated measures with a focus on reducing their population. The main period for snail eradication is late spring and early summer, especially before the peak snail breeding season in May and June. During this period, the environment for snail breeding should be deteriorated, and the specific measures are as follows:

1. Controlling soil moisture plays a key role in the prevention and control of snails, and there is more rain in the first half of the year, especially in areas with high groundwater levels, so ditches should be opened in time to remove stagnant water and reduce soil moisture.

2. Artificial hoeing or spraying herbicides to remove weeds around green spaces, flower beds, and ditches, and remove lush vegetation, plant residues, stones and other debris on the surface, which can reduce humidity, reduce the hiding place of snails, and worsen the place where snails live.

3 Before the end of spring and the beginning of summer, the soil should be loosened or turned frequently, so that the snails and egg masses are exposed to the surface of the soil and die in the sun. In winter and spring, when the ground is cold, ploughing can expose some eggs to the ground and be frozen to death or eaten by natural enemies.

4 Manual pick-up is time-consuming but effective. Insist on catching on the soil surface and green leaves before sunrise or when the snail is active every day, so that the number of the population is greatly reduced and changed to once a week, and the caught snail must be killed, not thrown nearby, in case the eggs in the body can still hatch after the death of the mother.

5 Scattering quicklime strips is also an effective way to control snails. If you sprinkle lime strips on the edge of green areas, snails will lose water and die if they get lime on them. This method must be done while the green space is dry and can kill some of the adult snails or larvae.

6. Use chemical drugs for prevention and control, in the peak of the occurrence of 2 snail bait to kilogram per mu, or 5 mida (tetraacetaldehyde) snail killing granules per mu to kilograms, or 8 snail pellets, 10 paraacetaldehyde (snail enemy) granules to 1 kilogram after stirring dry fine soil or fine sand, evenly sprinkled on the lawn soil surface in the evening. Put up to 20 to 30 grains at the base of the adult plant, and the snail killing effect is better. There are some other control methods, such as in the early morning, when the snail dives into the soil (cloudy days can be in the morning) with copper sulfate 1800 times liquid or 1 salt water spraying control.

Spray 800 to 1000 times of snail or 70 to 400 times of ammonia for prevention and control. It is recommended that these drugs be used alternately to ensure that the snails are killed and that they prevent the development of resistance.

In fact, using the habits of snails, you can also control snails in vegetable fields without pesticides, and recommend several methods: 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, and the snails will not climb up the stems and leaves to bite the stems and leaves. Second, sprinkle lime powder After heavy rain, sprinkle a layer of lime powder around the vegetables, about 3 5 mm thick and about 40 50 cm wide, for the snails that climb higher places, after the lime powder, they will be salted to death by lime powder.

3. Spray tea bran liquid with 1 kg of tea bran, process it into powder, add 10 15 kg of water, stir 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 vegetable crowns, you can kill the snails. The above prevention and control methods do not have any toxic residues, will not pollute vegetables and melons and fruits, spray or sprinkle on the same day, and can be harvested on the day of hunger, without endangering human health.
