Tracer studies with radioactive 2,4-D in bean, cotton, and cucumber plants confirmed previous findings that 2,4-D penetrates the cuticle of sprayed leaves, migrates to the phloem, and is transported in that tissue along with food materials in the plant. Freeze-dried plants were radioautographed to determine the rate and direction of translocation and the amount of chemical moved to various parts of the plant.
