Description and Uses

Malathion, a clear amber liquid, is sparingly soluble in water but soluble in a majority of organic solvents. The U.S. Environmental Protection Agency (U.S. EPA) grouped malathion under GUP, meaning general use pesticide. It is used as an insecticide as well as an acaricide for the control of pests. Malathion is used for the control of sucking insects and chewing insects on fruits and vegetables. Malathion is an effective insecticide for the control of several household pests such as houseflies, cockroaches, mosquitoes, aphids, animal ectoparasites, and human head and body lice. Malathion is also found in formulations with many other pesticides.

Insecticide for control of sucking and chewing insects and spider mites on vegetables, fruits, ornamentals, field crops, greenhouses, gardens and forestry.
