Extremely toxic; probable oral lethal dose to humans 5-50 mg/kg or between 7 drops and 1 teaspoon for a 70 kg (150 lb.) Email Print Friendly Share. Monocrotophos is an organophosphate insecticide, which is a type of pesticide. An Egyptian cotton leafworm, Spodoptera littoralis (Boisduval), sampled in 5 provinces of the Nile Delta showed uniform resistance (R) towards monocrotophos. Against monocrotophos, all developmental stages of S. littoralis were resistant and differences in R-S factors depended either on the mode of application or the stage of development. Humans exposed to large doses of an OP (methamidophos, fenthion, dimethoate, monocrotophos, etc.) The same populations were uniformly sensitive (S) towards profenofos, a new organophosphate insecticide. Don't already have an Oxford Academic account? Its low R-S factor of 6×, therefore, cannot be due to oxidative metabolism. Broad spectrum, systemic with stomach and contact action.
