摘要：

Variation in toxicity among formulations and species makes it difficult to extrapolate results to all species and all formulations of herbicides. The authors exposed larval wood frogs (Lithobates sylvaticus) from 4 populations to 2 glyphosate-based herbicides, Roundup Weed and Grass Control (R) and Roundup WeatherMax (R). The 96-h median lethal concentration values for both formulations varied among the populations (Roundup Weed and Grass Control, 0.14mg acid equivalents (a.e.)/L to 1.10mg a.e./L; Roundup WeatherMax, 4.94mg a.e./L to 8.26mg a.e./L), demonstrating that toxicity varies among the formulations and that susceptibility may differ among populations.
