Radioactive 2,4-D was applied first to greenhouse-grown morning-glory seedlings to compare various formulations. Emulsifiable acid and heavy ester formulations proved superior to the older salts and light esters, and the addition of a surfactant was found to increase absorption and translocation.
Field studies revealed that 2,4-D moves most actively in plants growing in moist soil, that movement is most rapid and extensive in plants in the seedling stage, and that 2,4-D moves where foods are moving.
