Malathion is a low toxicity, broad-spectrum insecticide, and miticide with contact and stomach toxicity. It also has the function of fumigation. It is fast-acting and high efficient.
Malathion can be used for prevention and treatment of rice, wheat, cotton, vegetables, tea, fruit tree pests such as aphids, planthoppers, rice leafhoppers, rice thrips, Ping borer, scale insects, red spider, gold shells, leaf miner, leaf-hop insects, cotton leaf-roller moth, stick insects, vegetables borer, tea leafhopper, fruit borer.
Malathion is widely used in agriculture and horticulture and can also be used for family.

Biochemistry: Cholinesterase inhibitor; proinsecticide, activated by metabolic oxidative desulfuration to the corresponding oxon.
Mode of action: Non-systemic insecticide and acaricide with contact, stomach, and respiratory action.
Uses: Used to control Coleoptera, Diptera, Hemiptera, Hymenoptera and Lepidoptera in a wide range of crops, including cotton, pome, soft and stone fruit, potatoes, rice and vegetables. Used extensively to control major arthropod disease vectors (Culicidae) in public health programmes, ectoparasites (Diptera, Acari, Mallophaga) of cattle, poultry, dogs and cats, human head and body lice (Anoplura), household insects (Diptera, Orthoptera), and for the protection of stored grain. Typical application rates for agricultural uses 0.5-1.25 kg/ha.
Phytotoxicity: Non-phytotoxic in general, if used as recommended, but glasshouse cucurbits and beans, certain ornamentals, and some varieties of apple, pear, and grape may be injured.
Formulation types: DP; EC; EW; UL; WP.
Compatibility: Incompatible with alkaline materials (residual toxicity may be decreased).
Oral: Acute oral LD50 for rats 1375-5500 mg/kg (pure), mice 775-3320 mg/kg.
Skin and eye: Acute percutaneous LD50 (24 h) for rabbits 4100-8800, rats >2000 mg/kg.
Inhalation: LC50 (4 h) for rats >5.2 mg/l.
NOEL: In 2 y trials on rats, the only effects seen at 500 ppm (29 mg/kg b.w. daily) was inhibition of cholinesterase in plasma and red blood cells.
ADI: 0.3 mg/kg b.w.
Toxicity class: WHO (a.i.) III; EPA (formulation) III (Fyfanon tech. and 5 EC)
