Virginia chain fern (Woodwardia virginica (L.) Smith) was controlled by 2,6-dichlorobenzonitrile (dichlobenil) in cranberry bogs on a St. Johns soil at Chatsworth, New Jersey, in experiments conducted during 1960, 1961, 1962, 1963, and 1964. The treatments were applied at emergence of the weed. Stalk counts of the fern were recorded the year following treatment. Excellent control was obtained at either 4 or 8 lb/A of dichlobenil. No re-growth occurred in subsequent years.
