The effect of 0.0001 and 0.00001 mg/L concentrations of Liquid Edger (LE) herbicide was evaluated on the parental generation, F1 and F2 of Artemia franciscana. The criteria evaluated were parental life span, survival to adulthood, fecundity, fertility and sex ratio. Only the parental generation was directly exposed to the herbicide. Only the F2 generation was evaluated for survival to adulthood and sex ratio. The 0.00001mg/L treatment of LE reduced the life span of females from the parental generation (P<0.005). The longevity of F1 females whose parents were exposed to the 0.00001mg/L treatment was significantly reduced (P<0.005). Parental females that were exposed to either of the treatments released significantly fewer broods than those from the controls (P<0.005). F1 females did not have significantly fewer broods (P>0.005). Parental females that were exposed to either of the treatments had significantly lower fecundity and fertility than did control females (P<0.005). F1 females from treated parents did not have significantly lower fecundity or fertility than did control F1 females (P>0.005). Liquid Edger did not affect survival to adulthood or sex ratio of the F1 or F2. Liquid Edger caused female debility and the F1 generation showed effects probably caused by residues of pesticide that were passed from the mother to the offspring.
