Control of insect pests (flies, mosquitoes, cockroaches, fleas, ants, ticks, lice, etc.) in public health situations and animal houses, and control of animal ectoparasites.

Phytotoxicity: Non-phytotoxic when used as recommended. Some varieties of apples and cotton may be injured.

Formulation types: DP; EC; GR; HN; PO; UL; WP.

Compatibility: Incompatible with insecticides and fungicides which are highly alkaline.

Mammalian toxicology

Algae: ErC50 for Scenedesmus subspicatus 1.79 mg/l.

Bees: Toxic to bees.

Worms: LC50 for Eisenia foetida 375 mg/kg dry soil.

Environmental fate

Animals: In mammals, following oral administration, elimination is mainly in the form of hydrolysis products in the urine. Major metabolites are fenthion sulfoxide, fenthion sulfone and their oxygen analogues. These metabolites are hydrolysed in further degradation, forming the corresponding phenols.

Plants: In plants, fenthion is oxidised to the sulfoxide and sulfone, both of which possess insecticidal properties, and to the monodesmethyl compound of fenthion sulfoxide. Further degradation occurs to the sulfone phosphate, which undergoes hydrolysis.

Soil/Environment: Koc 1500. In sediment/water system with and without plants, DT50 is c. 1.5 d. The degradation of fenthion occurs rapidly under aerobic conditions, forming the metabolites fenthion sulfoxide, fenthion sulfone, followed by the analogous phenol compounds.
