Organophosphorus Pesticides

Organophosphorus Pesticides

Organophosphorus pesticides are widely used insecticides functioning through irreversible inhibition of acetylcholinesterase, causing accumulation of acetylcholine and severe disruption of nerve transmission. They provide strong control of a broad range of pests including aphids, borers, leaf miners, and household insects. Common compounds include chlorpyrifos, diazinon, malathion, and phorate. Their systemic and vapor action enhances effectiveness in dense canopies and soil environments. Although effective, organophosphates pose risks of acute toxicity to humans, wildlife, and beneficial insects, requiring careful dosage, protective equipment, and regulatory oversight. Environmental concerns include water contamination and non-target exposure. Due to their potency and reliability, organophosphorus pesticides remain key components of pest management, though increasingly supplemented by safer modern chemistries.
