Slugs are a huge problem in many crops, especially vegetables, fruits and grains. Gastropods have an extensive diet, which depends on the specific type of slug and habitat.

Every year, farmers are faced with the task of protecting grapes, potatoes, citrus fruits, legumes, various berries, tomatoes, cucumbers, etc. from these pests.

Slugs feed on both fresh crops, grain, foliage, stems, and ripe fruits with tubers. Sweet berries are a special delicacy for them. For more information on how to deal with slugs on vegetables and berries, read here.

General information

Eating crops - this is not the only threatcoming from slugs.

Slimy pests often feast on various mushrooms, subsequently suffering fungal diseases to gardens and farmers' fields.

Then you have to look for means of struggle not only against the slugs themselves, but also the consequences of their stay in the form of potato late blight, downy mildew or cabbage spot.

The question arises: "How to treat plants from slugs and kill them?", "How to poison slugs in the garden?"

How to poison?

When prophylaxis such as draining areas, land cultivation with lime or ash is too late, it is time to look for serious measures to combat slugs.

Many garden owners recklessly arm themselves with standard poisons from insects (insecticides), but only waste money and effort.

To most of these drugs slugs are indifferent... The poison from slugs must be selected with great care. Most often it is a powerful slug chemistry, as it is the most effective remedy. There are specially formulated molluscicides or limacids, i.e. pesticides aimed at killing slugs.

Among the approved for use are such drugs, as a domestic "Thunderstorm" or "Slime Eater"... Chemicals can be based on metaldehyde, dichlorosalicylanilide, copper or copper sulfate, mercury, tin or lead compounds, bleach, etc.

They all differ in their spectrum of action., specific type of shellfish, release form, hazard class, dosages and other characteristics.

Effective remedies

To surely scare away and kill garden pests, you can use folk remedies - timely clean the cultivated plantings from weeds, sprinkle the ground with lime, potassium salt, ash, superphosphate or hot pepper.

Farmers often set up traps or obstacles such as ditches or "steam rooms" scatter sharp shells from eggs and nuts in the path of seedlings... Mechanical methods of struggle are always relevant. However, when the leaves begin to curl, the manual collection of snails and slugs becomes quite laborious.

The most commonly used drugs against snails or slugs are Thunderstorm, Meta, Metaldehyde and Ulicid. They are produced in the form of crystalline substances, granules with the addition of bran to attract pests, soluble powder in water or other liquids.

Depending on the type of poison, they are used against aquatic molluscs, distributed near water sources or directly in the reservoirs themselves, and also distributed on the surface of the soil - against land slugs.

Similar to Ulicide, there are environmentally friendly drugsbased on iron phosphate. Among these, the most common are "Escar-Go", "Sluggo" and "SlugMagic". Anti-slug chemistry must be used with caution.

Whatever drug for slugs the gardener uses, he must remember that you must immediately stop treating the soil and plants with poison at least 2-3 weeks before the harvest ripens, so that berries, fruits or vegetables do not become poisonous to humans.

Drugs

"Thunderstorm" ("Meta")

Slug Thunderstorm Originally Made in Switzerland called "Meta", and for about a century has been considered one of the most productive and safe means for the destruction of garden slugs.

  • What is produced (release form)? Packaged in the form of blue granules. One package contains 15 g or 60 g of the drug.
  • Chemical composition. The base substance of "Thunderstorms" is metaldehyde and other auxiliary additives.
  • Mode of action of the drug. Since it is an intestinal and contact preparation, it exerts its effect upon direct contact with the slug's body.

    The granules quickly absorb moisture and literally dry out pests, depriving them of protective mucus and the ability to move easily. Also, slugs willingly eat granules and die from poisoning after 2 hours.

  • Duration of drug action. 2 to 3 weeks. Expiration date 24 days.
  • When to apply? The effectiveness of the drug has been proven even after heavy rainfall. Thunderstorm can be used both in dry, calm weather and in the rainy season, when slugs are attracted by a humid environment. Pellets with the first sprouted stems and blossoming leaves are scattered on the land plot.
  • Traditionally, Thunderstorm should be used in early spring to protect young, immature shoots.

  • Dosage. The standard consumption rate is 30 g of the drug per 10 sq. m. territory or 15 g per 5 sq. Enough 2-3 treatments per season.
  • Mode of application. The drug is optimal for the protection of grapes, berries, as well as citrus, vegetable, fruit and flower crops. The granules of the substance are scattered under the plants in places where slugs accumulate: between the rows and on the paths.

    Avoid getting granules into the leaves of cabbage or lettuce heads, so that after the poisoning does not end up in food. The pellets are destroyed by incineration.

  • Toxicity. Due to the content of some harmful additives in the granules, "Thunderstorm" kills slugs, but can attract other pests and scare off birds that would help fight them.

    It is undesirable to use "Thunderstorm" in premises for storing crops, such as cellars with potato tubers and other vegetables.

The drug is practically harmless to earthworms, bees, fish, algae and most plants.

Hazard class for humans - 3.

When working with a moderately hazardous substance you need to protect your eyes and respiratory tract with glasses, respirator or gauze bandage.

The drug is extremely toxic for adults, and for children and pets, if ingested with food or in the eyes. Any vegetables and fruits after harvest rinse thoroughlyif Thunderstorm was used nearby.

Many drugs of the molluscicide class are available in colored granules or in the form of balls. Despite the unnatural blue tint for nature, pets can mistake the preparation scattered in a heap for food or sweetness. It is better to buy substances in the form of elongated granules.

"Metaldehyde"

One of the most famous and inexpensive drugs used in the fight against slugs and snails.

Most often there are drugs produced by "Lonza" and "August", "Green Pharmacy Gardener".

  • Mode of action of the drug. It attracts pests in the same way as regular beer or fermented fruits.
  • Duration of drug action. 14 to 21 days. At the end of the shelf life, it completely decomposes in the ground.
  • When to apply? Manufacturers claim that the effectiveness of the drug persists even after frequent rains, but the experience of gardeners shows that the granules quickly dissolve in water (2-3 precipitation is enough).

    Has a destructive withering effect on slugs in direct contact. If swallowed, it destroys the digestive system.

    The drug should be scattered in warm and dry weather, with the first appearance of slugs, in the midst of spring. It does not require special preparation, it is produced in ready-made granules. The consumption of the substance is 15 g per 5 sq. M.

  • Toxicity. 3rd class of danger to humans. The drug is dangerous for pets (especially dogs), adults and children. Not too toxic for fish, microorganisms and worms.
  • Experts advise against scattering "Metaldehyde" next to fruiting plants. Even after thorough washing of vegetables, fruits and berries, where the drug has been scattered nearby, there is a minimal risk that some of the poison remains.

    "Ulicid"

    An effective and natural remedy used in the fight against slugs and snails, which kills pests by intestinal contact. Produced in Ukraine.

    • What is produced (release form)? Sold in packs of 20 g (70 pieces) and 50 g (50 pieces), contains small blue colored bait pellets.

    • Consumption rate: 3-5 gr per 1 sq. plot. One treatment per season is enough.
    • Mode of application. The granules are scattered in the indicated doses under the bushes of plants or in the paths and between the rows.

    Conclusion

    Regardless of the choice, try to give preference to drugs with a low dosage toxic substance. Farmers can choose from both chemical and natural products.

    The former are known for their high efficiency., but a sufficient level of danger to humans, animals or edible plants. The latter are the safest.

    Try to resort to strong chemical poisons, to kill slugs and snails, only if traditional methods of struggle no longer help. Read about how to deal with slugs in the basement here.
