SUMMARY Twenty‐five herbicides have been tested for their toxicity to hen embryos at various concentrations, using an egg‐injection technique. Paraquat was the most toxic, giving a complete kill at a concentration in the egg of 0.3 ppm; two other compounds related to it were almost completely lethal at 10 ppm. Of the other compounds, seventeen had little or no effect at 50 ppm and of these eight had none at 100 ppm. Except for feather blanching, caused by some of the substituted phenoxy‐acids, no teratogenic effects were found.
