Thiocyclam-hydrogen oxalate solution is primarily used as an insecticide in agricultural practices. It is effective against a variety of pests, particularly those affecting crops such as rice, vegetables, and fruits. The solution works by disrupting the nervous system of insects, leading to their paralysis and eventual death. It is often applied as a foliar spray, ensuring thorough coverage of the plant surfaces to maximize contact with the target pests. Due to its mode of action, it is particularly useful in controlling pests that have developed resistance to other types of insecticides. However, it is important to follow recommended guidelines for application to minimize any potential impact on non-target organisms and the environment. Proper handling and storage are also crucial to maintain its efficacy and ensure safety during use.
