This study investigated the developmental toxicity of a plant growth regulator (a type of pesticide) using the frog embryo teratogenesis assay-Xenopus (FETAX). Xenopus laevis embryos were exposed to 11 different concentrations of gibberellic acid (GA(3)), from stage 8 to 11, for 96 h under static renewal test conditions. The median lethal concentration (LC50), malformation (EC50), non-observed adverse effect concentration (NOAEC), and lowest observed adverse effect concentration (LOAEC) were calculated.
