Description and Uses

Pirimicarb is a colorless solid that is moderately soluble in water, acetone, ethanol, xylene, and chloroform.
Pirimicarb is produced by reaction of 2-dimethylamino- 5,6-dimethyl-4-pyrimidone with dimethylcarbamic acid chloride in the presence of a base or phosgene and dimethylamine. Pirimicarb is a systemic, selective aphicide used largely on grain crops, but also on ornamentals, cotton, fruit, and in greenhouses.

Insecticide.
