Description

coumaphos is a tan crystalline solid with a slight sulfur odor. It is insoluble in water, slightly soluble in acetone, chloroform, and ethanol, and soluble in organic solvents. It is used for the control of a wide variety of livestock insects, including cattle grubs, screwworms, lice, scabies, fl ies, and ticks. It is used against ectoparasites, which are insects that live outside the host animals, such as sheep, goats, horses, pigs, and poultry. Coumaphos is incompatible with pyrethroids a
