Abstract/Contents:"Turfgrass seedlings often fail to safely grow in soil containing herbicide residues. Misuse or accidental treatment with chemicals can result in severe turfgrass injury. Studies were initiated to determine if activated charcoal would absorb these chemicals and nullify their harmful effects. Also studied was the effect charcoal may have on the future performance of herbicides. Herbicides and chemicals were applied to seedbeds and turfgrass areas. Seedlings were made at various time intervals after treatment using varying rates of activated charcoal. Estimates of turfgrass cover indicated the degree of chemical toxicity. Where chemicals were applied to grass, injury estimates showed if charcoal could alleviate damage. Herbicides were applied to areas previously treated with charcoal and weed control estimates were used to indicate any change in herbicidal activity. Turfgrass establishment was inhibited in soil containing residues from most herbicides used for preemergent crabgrass control. This included such herbicides as bandane, benefin, bensulide, DCPA and terbutol. Inhibition was also noted from a mixture of 2,4-D, dicamba, mecoprop and silvex. These herbicides are generally used for broadleaved weed control. Satisfactory turfgrass stands were obtained when activated charcoal was used in seedbeds containing the above herbicides. Charcoal was effective in alleviating grass damage from some chemicals. Such a chemical was the brush-killer combination of 2,4-D + 2,4,5-T. Early charcoal treatments were found to be the most effective in alleviating damage. The future performance of herbicides, such as bensulide, was not affected by charcoal used previously in seedbeds. Some reduction in herbicide effectiveness was noted when charcoal was used on turfgrass. As time progressed, the charcoal caused less reduction in effectiveness. Higher rates of charcoal caused greater reductions in herbicide effectiveness, while increased herbicide rates counteracted the retarding effect of activated charcoal."
