Activated Carbon Root Dips on Transplanted Strawberries

Excellent protection from 2-chloro-4,6-bis(ethylamino)- s -triazine (simazine) injury at twice the dose needed for weed control was obtained by dipping the roots of strawberry plants ( Fragaria grandiflora Ehrh.) in a 10% slurry of activated carbon before transplanting. Protection was greater when the roots were dipped in the slurry of activated carbon than when activated carbon was applied in the transplant water. Protection was obtained from three different activated carbons. Protection from injury to varying degrees was observed when several other herbicides were used.
