Abstract

High concentrations of arsenic (As) may be expected on Coastal bermudagrass forage harvested soon after application of organic arsenicals for weed control. Stage of plant development at treatment, rainfall between treatment and harvest, rate of application of arsenical herbicides, and the amount of growth between treatment and harvest are factors influencing As residue levels in harvested material. Regrowth following removal of treated growth had a lower As concentration. Treatment application on short grass and removing and discarding the treated foliage appeared to be the most effective means of reducing As residues.
