Field studies conducted during 1967 and 1968 evaluated activated carbon as an adsorbent for the reduction of dichlobenil (2, 6-dichlorobenzitrile) plant toxicity occurring in newly established nursery plantings. Eight lb. per acre of dichlobenil was a critical level for plant toxicity control through root dips of activated carbon since visual injury was often pronounced where dichlobenil was increased above this rate. Increases in the activated carbon dip concn did not enhance plant protection. Activated carbon dips are most effective where herbicide injury is expected to be marginal and when residues will rapidly dissipate from the soil immediately surrounding a plant’s developing root system.
