CATDOLL : CATDOLL: What medicine is effective in killing snails?

1. Does highly effective chlorfenapyr kill snails?

Can kill snails.

High-efficiency cyhalothrin belongs to the pyrethroid insecticide, which has contact and stomach poison effects and a broad insecticide spectrum. It mainly controls pests with piercing-sucking mouthparts such as aphids, and can also control pests with chewing mouthparts, and can also kill mites. It has a long lasting effect, kills insects quickly, and has strong knockdown power, but it does not have a systemic effect and has no control effect on snails. It is not a snailicide, so high-efficiency cyhalothrin cannot kill snails or the effect is very poor.

2. Can ordinary pesticides be used to kill snails by sprinkling salt on them?

cannot

To prevent and control snails, you cannot use pesticides for controlling ordinary insects. These conventional pesticides have basically no effect on snails, which belong to the mollusc family. Even if you spray, scatter, or apply these pesticides on the ground, they will have no effect.

In order to achieve the goal of "putting the medicine into the field and completely eliminating snails", it is necessary to use special drugs for controlling snails, slugs, apple snails and other mollusks. According to the actual control effect in the field, the best drug for controlling snails is metaldehyde or drugs containing metaldehyde as an effective ingredient (selective snailicide, which kills snails but does not harm crops), such as the common 6% metaldehyde granules and 80% metaldehyde wettable powder on the market, or other compound drugs containing metaldehyde as an effective ingredient.

Whether it is granules or powders, metaldehyde can effectively kill all kinds of soft snails, including snails. Because metaldehyde or drugs containing metaldehyde active ingredients, after contact with snails or after being accidentally ingested by snails,

Not only will it destroy the enzyme activity in the snail's body, paralyze the snail's nerves, and reduce the snail's ability to move, but this drug will also cause the soft-bodied snail to continue to secrete large amounts of mucus and continue to become dehydrated until the snail eventually dies from excessive dehydration. This is what we often call the stomach poison method of killing insects.

3. Ants and snails have become a plague. What pesticide can be used to kill them?

Chemical control.

(1) Use 0.50-0.6 kg of 6% Metaldehyde (tetraacetaldehyde) snail-killing granules, 8% Metaldehyde granules or 2 kg of 10% Metaldehyde (snail enemy) granules per mu, mix with appropriate amount of fine soil or fine sand, and spread evenly in the field in the evening.

(2) In the early morning when snails have not yet burrowed into the soil, spray with 800-1000 times diluted copper sulfate or 1% salt water, the control effect can reach more than 80%.

(3) If snails are found causing damage, spray the leaves with 1500 times diluted 90% crystalline dichlorvos.

4. What is the nemesis of snails and why can’t we always eliminate it?

The nemesis of snails is a pesticide called "Suluonicide", whose main ingredients are metallic iron and copper. This pesticide mainly destroys important organs in the snail's body, such as the liver and kidneys, making it impossible for the snail to metabolize and grow normally, eventually leading to death. In addition, there are some natural enemies, such as centipedes, earthworms, and certain insects that can pose a great threat to snails. However, due to the large number of snails, strong reproductive capacity, and strong adaptability, pesticides such as Suluonicide often have limited effects, and the continuously multiplying snails will re-occupy people's courtyards and fields. Therefore, in addition to chemical pesticides, people can adopt more ecological and environmentally friendly methods to control the number of snails, such as using organic fertilizers, plant extracts, biological control and other measures to ensure that the number of snails does not grow excessively.

5. How to kill snails quickly and cleanly?

The quickest and cleanest way to kill snails is to use the pesticide metaldehyde.

This is the most effective method. If it is a flower pot or vegetable garden, just sprinkle a circle around the root system, snails, slugs or other mollusks can be "dissolved". After sprinkling it at night, you can find that only the shells of the snails are left the next morning. The effect is still very good.

6. Which pesticide is better for killing small snails?

Snails like moisture and are afraid of light.

7. Can the pesticide cypermethrin cure snails?

The pesticide cypermethrin belongs to the pyrethroid insecticide, which has contact and stomach poison effects. It is mainly used to control pests with chewing mouthparts such as cabbage worms. Since it does not have systemic effects, it cannot kill snails. Snails belong to the snail family and do not eat the stems and leaves of crops. In actual production practice, metaldehyde is used to control snails. Therefore, cypermethrin cannot kill snails.

8. What should I spray with green onions to kill snails?

Spray metaldehyde.

The use of the pesticide metaldehyde is the simplest and most effective method. If it is a flower pot or vegetable garden, just sprinkle it around the root system, and snails, slugs or other mollusks will be "dissolved". Sprinkle it at night, and you will find that only the shells of the snails are left the next morning. The effect is still very good.

The amount used in flower pots and vegetable gardens is small, we can just spread it as we see fit. If it is a large-scale planting, such as cabbage, soybeans, beans, cucumbers, etc., it is recommended to spread 500 grams of 64% tetraacetaldehyde granules per mu of ground.
