Synopsis Amine and ester formulations of 2,4‐D did not reduce the germination of seed of rose clover, Trifolium hirtum All., produced after applications made during the rosette and early bud stages. However, seed and forage yields were reduced by both formulations, the ester formulation being more toxic than the amine. Both formulations drastically reduced seed production and germination when applied during the bloom stage. Neither form caused significant damage if applied when seed was ripe.
