Isazophos is primarily used as an insecticide and nematicide in agricultural practices. It is applied to soil to control a variety of soil-dwelling pests, including nematodes, beetles, and other insects that can damage crops. The chemical works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in pests, leading to their paralysis and eventual death. Farmers often use Isazophos to protect crops such as corn, potatoes, and vegetables from infestations that can significantly reduce yield and quality. It is typically applied before planting or during the early stages of crop growth to ensure effective pest control throughout the growing season. The chemical is usually incorporated into the soil to target pests that reside underground, providing long-lasting protection. However, due to its high toxicity to non-target organisms, including humans, and its potential environmental impact, the use of Isazophos is strictly regulated in many countries. Proper handling, application, and disposal practices are essential to minimize risks to human health and the environment. In some regions, its use has been phased out or restricted in favor of safer, more sustainable pest control alternatives.
