Abstract | The effects of the herbicide alachlor, in both technical grade and commercial product form (Lasso(R)), were tested for acute toxicity on larvae of the estuarine crab Rhithropanopeus harrisii. The generalized effect is a reduction in survival and a lengthening of developmental time with an increase in concentration. The LC(sub 50) values were inversely proportional to exposure time and ranged from 10 to 27 ppm. Lasso(R) was slightly more toxic than technical grade alachlor.
