Which chemical is used to kill slugs in agricultural practices?

The correct choice, Molluscide, is specifically designed to target and eliminate mollusks, which include slugs and snails. These compounds work by disrupting the biological processes of these pests, ultimately leading to their death. Molluscicides are an important tool in agricultural practices, especially for crops vulnerable to damage from slugs, as they can effectively reduce pest populations and protect plant health.

The other options correspond to chemicals that target different types of organisms. Nematicides are formulated to control nematodes, which are microscopic worms that can damage plant roots. Miticides focus on controlling mites, typically small arachnids that can cause significant harm to a variety of crops. Larvicides are designed to kill the larval stages of insects and are used primarily against pests like mosquitoes and flies. Each of these chemicals serves a unique purpose in pest management, but none are effective against slugs, which is why molluscides are the appropriate choice in this context.
