ResumoAbstract Cuscuta spp . (dodder) are phanerogamic holoparasites. Swamp dodder ( C. gronovii Willd. ex R. & S.) is a problem weed in cranberry ( Vaccinium macrocarpon Ait.) in Wisconsin and Massachusetts, causing yield losses as high as 80% to 100% (Devlin and Deubert, 1980). At rates used in cranberry, the registered herbicides, granular chlorpropham (1-methylethyl 3-chlorophenylcarba-mate) and granular dichlobenil (2,6-dichlorobenzonitrile), are not totally effective, causing a steady increase in swamp dodder infestation. Since chlorpropham use was discontinued in 1988, dichlobenil is the only registered herbicide for dodder control in cranberry. The objective of this research was to investigate preemergence herbicides for swamp dodder control in cranberry.
