Snails belong to the mollusk phylum, gastropods, is an important pest on vegetables, the most common in China is the same type of snail, gray snail, snail food miscellaneous, can eat a variety of vegetables of different tissue parts, mainly leaves. It can eat both fresh vegetable plants and vegetable residues, such as rotten vegetable leaves, vegetable roots, and unripe organic fertilizer.
Snail life is hidden, medicinal control is difficult: snails are hiding in the soil cracks in summer and winter, spring and autumn are harmful, more lurking during the day, or lurking in the soil, or lurking in the back of the leaves of the plant, or lurking between the leaves of Chinese cabbage, Cabbage, lettuce, kale, etc., only at night to come out to eat, if it is rainy, day and night can be eaten, because snails are soft animals, insecticides have no preventive effect on it.
The use of mulching can significantly inhibit the activity and harm of snails. Frequent cleaning of the countryside, timely cultivation, destruction of their habitat and spawning sites, reduce the source of insects. In autumn and winter, eggs and overwintering adults can be turned over to the surface, sunburned or eaten by predators. Where snails are more severe, leave a small patch of weed when ploughing the land in winter, spring and autumn, lure the snails, and then concentrate on extermination.
After ploughing the land in spring and autumn, the furrow weeds and crop residues can be removed in time, and leaves, weeds and vegetable leaves can be used to make a lure pile in the vegetable field, sprinkle water to cause a wet environment to lure snails, and concentrate on catching and eliminating them after dawn. After the vegetables are harvested, the weeds and crop residues in the vegetable fields are removed in a timely manner. Do not apply uncorried organic fertilizer.
Quicklime blockade control: After the colonization of vegetables such as Chinese cabbage and Chinese cabbage, sprinkle a layer of quicklime around the plant in time, but do not sprinkle it on the front of the leaf, so as not to affect photosynthesis. Snails will die when they come out at night to eat quicklime. Or sprinkle quicklime on the edge of farmland ditches and ridges to form a blockade zone. Using 5 to 7 kg of quicklime per 667 square meters can prevent snails from entering the vegetable field in a short period of time.
Chicken and duck capture: sunny night, generally after 19:00 in the evening, the snail can be captured when it starts to move, the best time to catch is 16:00-17:00, for 3 to 4 consecutive nights, basically can control the snail damage. It can also be captured early in the morning after rain, cloudy or sunny days, but the effect is poor.
