methomyl

A highly toxic restricted carbamate-type agricultural pesticide used for alfalfa, oranges, apples, vegetables and spices; methomyl is a cholinesterase inhibitor with muscarinic effects which is toxic in humans. In high doses, it causes lacrimation, salivation, bronchospasm; at lower dosese, nausea, vomiting, dizziness

The pain on deep breathing (10.5%) reported by the farmers can be due to exposure specifically to Lannate which has an active ingredient of methomyl. In the survey, 15.2% of the farmers reported of using Lannate for insecticide control, hence, the consequent manifestation of respiratory symptoms among them.
