Description

Azinphos methyl is an organophosphate pesticide available as a white or colorless crystalline solid substance. Technical azinphos methyl is a brown waxy solid that is sparingly soluble in water, but very soluble in most organic solvents. It is incompatible with strong oxidizing agents, and is hydrolyzed by water, acids, and alkalies. Azinphos methyl is used on many crops, especially apples, pears, cherries, peaches, almonds, and cotton for the control of a variety of crop pests and fruit crop p
