The commonly used amides and acetamides include bensulide, dimethenamid-P and propanil. Dimethenamid-P is characterised by a moderate acute toxicity orally and low acute toxicity dermally or by inhalation (Oral LD50 of 371-429 mg/kg bw in male and 427 mg/kg-531 mg/kg bw in female rat). It is considered a skin sensitizer, mild skin irritant and practically non-irritant to the eyes (JMPR, 2005)
Dimethenamid is a racemic mixture of the M and P stereoisomers, whereas P isomer has useful herbicidal activity. Both substances produce only mild reversible skin and eye irritation and skin sensitization . . .
