Field bindweed control in vineyards
Abstract Not Available – First paragraph follows: Field bindweed (Convolvulus arvensis) is a widespread problem in coastal vineyards of central and northern California. Field trials by the Agricultural Extension Service since 1963 have compared several formulations, rates, and timing of 2,4-dichlorophenoxyacetic acid (2,4-D) sprays. Wax bars impregnated with 2,4-D have also been tried. None of the treatments in these trials have given commercial season-long control (table 1).
