Dissipation of Residues of 2,4‐D in Static Water

Abstract

The rate of dissipation of residues of 2,4‐D (2,4‐dichlorophenoxy acetic acid) at the point of application, applied for control of aquatic vegetation, was found to be affected by the rate of treatment, depth of water, mean temperature, and time after treatment. For the standard rate of treatment, i.e., 4.48 kilograms acid equivalent per hectare (kg ae/ha) there was a decrease of 58 parts per billion (ppb) in residue for each 0.61 m increase in depth of water treated, a decrease of 115 ppb in residue for each 7C increase in mean temperature, and a decrease of 53 ppb in residue for each 7‐day interval of time after treatment.
