Description
Acetamide acid (methomyl) is a carbamate broad-spectrum insecticide. Methomyl is
classified as a restricted use pesticide (RUP). It is a crystalline solid with a slight sulphurous
odour and very soluble in methanol, acetone, ethanol, and isopropanol. It decomposes
with heat and releases hazardous gases/vapours, such as sulphur oxides, methyl
isocyanate, and HCN. Acetamide acid (methomyl) is used both as a contact insecticide and
as a systemic insecticide. It is used as an acaricide to control ticks and spiders; as fly bait;
for foliar treatment of vegetable, fruit, field crops, cotton, and commercial ornamentals;
and in and around poultry houses and dairies.

Uses
Insecticide, nematocide. Insecticide. Methomyl is a pesticide. This mixture of two stereoisomers
is used as a foliar spary to control field crops,
stables and poultry houses, and in glasshouses on
ornamentals and vegetables, or in flypapers. Cases
have been reported in chrysanthemum growers and in
two women working in a plant nursery.
