- Use：
- Malathion is a clear amber liquid. It is sparingly soluble in water, but soluble in a majority of organic solvents. The US EPA grouped malathion under GUP. 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, and is an effective insecticide for the control of several household pests, such as housefl ies, cockroaches, mosquitos, aphids, animal ectoparasites, and human head and body lice. It is also found in formulations with many other pesticides.
