Abstract: The first season of small plot trials to evaluate thirteen weed control products for use as post-emergent foliar applications in cranberries were conducted at four sites, two in New Brunswick and two in Nova Scotia. Visual ratings on crop tolerance and weed control were taken at intervals throughout the summer. Yield data was collected from three of the four trial sites which were producing. Products which exhibited good characteristics for crop tolerance, weed control and yield include: Classic®, Ultim®, Sinbar® and Amber®. Considerable crop injury was caused by Amber® initially but the cranberry crop outgrew the symptoms. Products which exhibited fair characteristics include: Accent®, Kerb®, Peak® and Elim®. Products which exhibited poor characteristics include: Pursuit®, Fieldstar®, Devrinol®, Refine Extra® and Express®. Pursuit® caused unacceptable crop injury from which the plants did not recover.
