Using Methomyl Products Safely
date:2016/12/1   
Methomyl is extremely toxic if ingested and moderately toxic if inhaled. It is a cholinesterase inhibitor in humans at high enough doses; that is, it can overstimulate the nervous system resulting in nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.
To minimize health impacts, EPA classified methomyl products used in agricultural settings as “restricted use,” meaning they can be used only by or under the direct supervision of specially trained and certified applicators. Learn more about restricted use pesticides.
Methomyl dissolves in water and breaks down rapidly in soil, so it has a low persistence in the environment.
All registered methomyl products can be safely used by following label directions.
When handling methomyl products, users must follow the safety precautions found on the product label. These include:
wearing protective clothing and eyewear at all times;
distancing yourself from the chemical when mixing it;
using personal protective equipment like a respirator during application; and
observing re-entry intervals.
