Molecular formula: C8H19O2PS2
Relative molecular mass: 242.3
CAS No.: 13194-48-4
Physical characteristics:
Ethoprophos is a clear, pale yellow liquid;
boiling point: 86-91 °C (27.7 Pa);
density (d 20): 1.094;
Solubility: In water, 750 mg/L (at 25 °C) very soluble in organic solvents.
Stability: Ethoprophos is very stable in acid aqueous medium up to
100 °C, but is rapidly hydrolysed in alkaline media at 25 °C and above;
Vapour pressure: 46.7 Pa at 26 °C.
Toxicity, single dose:
Oral LD50:
Rat (M): 62 mg/kg b.w.; technical material in corn oil
Rat (F): 33 mg/kg b.w.; technical material in corn oil
Mouse (M,F): 31 mg/kg b.w.; technical material in water
Dermal LD50:
Rat (M,F): 226 mg/kg b.w.; technical material in water
Mouse: 18 mg/kg b.w.; technical material in acetone
Pig: 327 mg/kg b.w.; technical material, no vehicle
Inhalation LC50: (4 hour)
Rat: 250 mg/L air
Most susceptible species: Probably mice
Absorption route:
Ethoprophos may be absorbed from the gastrointestinal tract,
through the intact skin, and by inhalation of spray mist and dusts.
Mode of action:
Ethoprophos is a direct inhibitor of cholinesterases through
phosphorylation of the esteratic site of the enzyme. Accumulation of
acetylcholine at the nerve synapses and myoneural junctions causes
toxic effects.
Susceptible pests:
These include wire worms, nematodes and corn rootworms and soil inhabiting arthropods.
Use pattern:
It is almost exclusively recommended as a pre-plant, soil application for tobacco, sweet potatoes,
bananas, plantains, cabbage, corn, pineapple, sugar cane, soybeans, peanuts, cucumber, snap
and lima beans, potatoes and commercial turf.
