Most broadleaf weeds, and brush. Uptake and Translocation Readily absorbed through leaves or roots. Translocated primarily in phloem with the sugars but can also move with water in the xylem.
Accumulation is primarily in the young, rapidly growing meristematic regions of roots or shoots.
All weeds are more easily killed when growing rapidly in moist soil. Unfortunately,some broadleaf crops, garden and ornamental plants are as sensitive to 2,4-D as many weeds and only a trace of the chemical as spray drift, vapour drift or contaminant in soil or water may cause serious damage. The esters are the most active and can be used at the lower rates and for brush control. Since vapour drift is a potential problem with the ester formulations, only the amines should be used on lawns, or near gardens or susceptible crop areas.
