Snails are harmful animals. Snails are harmful in soybean seedling stage, which may cause damage to leaves and stems, delay the development of stiff seedlings and reduce the seedling rate. In the worst case, all the bean seedlings are eaten up, resulting in no seedlings. Comprehensive measures should be taken to control snails in soybean fields.

Snails generally refer to all terrestrial species of Gastropoda. Generally speaking, there is no distinction between aquatic snails and terrestrial snails in western languages. In Chinese, snails only refer to terrestrial species, and snails in a broad sense also include giant shield slugs. Snail is an animal, including many different families and genera. It feeds on plants and lays eggs in soil or trees. Common in tropical islands, but some live in cold regions.
