Organophosphates are: a. herbicides b. insecticides Dithiocarbamates are herbicides? True or False Solution True, because organophosphates are the reasons for many insecticides, herbicides, and nerve agents. Organophosphate pesticides degrade rapidly by hydrolysis on experience of sunlight, air, and soil, although small amounts is usually detected in food and drinking water. Their ability to degrade made them a good looking substitute for the persistent organochloride pesticides.
