Thiocyclam-hydrogen oxalate solution is primarily used as an insecticide in agricultural practices. It is effective against a range of pests, particularly those affecting rice crops, such as leafhoppers and planthoppers. The solution works by disrupting the nervous system of insects, leading to paralysis and eventual death. It is often applied as a foliar spray, ensuring direct contact with the pests. Due to its targeted action, it helps in maintaining crop health and yield without causing significant harm to non-target organisms when used as directed. Proper application and adherence to safety guidelines are essential to minimize environmental impact and ensure effective pest control.
