In comparison with the control, fecundity of C. affinis lowered by 75.6% at 10 mg/dm3 herbicide concentration and by 36−40% at concentration of 2.5−5.0 mg/dm3. The 0.001 mg/dm3 concentration was ineffective. This herbicide should be ranked among the toxic agents for aquatic organisms. %8 2007-12-12
