Snail drug control: use 1.6% tetraacetaldehyde 10kg/hm2 spray; or use 15% tetraacetaldehyde powder 50kg/hm2; 4% carbamate 100kg/hm2; copper sulfate 125~250kg/hm2; iron sulfate 125~250kg/hm2 spray.
You can also use 1%~5% shellac or 1%~1.5% ammonia solution ground spraying to control after 5 p.m., or spray plants with slightly higher than the conventional concentration of pesticides such as methamidophos and lecithin, which are poisoned and die after snails feed on them.
Salt can react to the snail surface. This is because the snail's surface (except the shell) has a layer of mucus that facilitates the snail's movement and skin-assisted respiration. When salt is sprinkled on, the snail's ability to move and breathe is reduced, and the mucus seeps outside the body, causing the snail's body to shrivel up and its cells to become dehydrated.
