Methomyl is widely used as a broad-spectrum insecticide in agricultural settings to control a variety of insect pests. It is particularly effective against pests that attack fruits, vegetables, field crops, and ornamental plants. The chemical works by inhibiting the activity of acetylcholinesterase, an enzyme essential for proper nerve function in insects, leading to their rapid elimination. In addition to crop protection, it is also utilized in non-agricultural environments, such as greenhouses and nurseries, to manage pest infestations. Due to its fast-acting nature, it is often applied as a foliar spray to quickly reduce pest populations and prevent crop damage. However, its use is carefully regulated due to its high toxicity to non-target organisms, including beneficial insects, birds, and mammals. Proper handling and application practices are essential to minimize environmental impact and ensure safety.
