Methomyl
Methomyl (pronounced me-THO-myl) is a highly toxic pesticide used to control insects in a wide variety of field crops, including fruits, vegetables, and ornamental plants.
Etymology
The term "Methomyl" is derived from its chemical structure, which includes a methyl group (meth-) and a carbamoyl group (-omyl).
Usage
Methomyl is a carbamate insecticide, meaning it works by inhibiting the activity of the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This leads to an accumulation of acetylcholine, causing rapid twitching and paralysis of the insect's muscles, ultimately leading to death.
Health Effects
Exposure to Methomyl can cause a variety of health effects in humans, including nausea, vomiting, abdominal pain, and in severe cases, seizures, and respiratory failure. It is classified as a by the World Health Organization.
Environmental Impact
Methomyl is highly toxic to non-target organisms, including birds, fish, and beneficial insects. It is also highly soluble in water, which means it can easily contaminate water sources if not properly managed.
