Abstract: Borage (Borago officinalis) is a potential new crop for New Brunswick producers. To reach commercial
production, several production issues will have to be dealt with, including registered weed control options. A trial was
initiated near New Denmark, New Brunswick to evaluate in–crop herbicides for weed control in borage.
Trifluralin was broadcast over the experimental area prior to plot establishment, so weed control ratings may not reflect
the potential weed spectrum in the field. Trifluralin, sethoxydim, clopyralid and glyphosate show promise at the
application rates and timings used in this trial and should be examined further. Crop injury to borage following linuron,
pendimethalin, glyphosate plus BAS 800H and nicosulfuron application was high, so these products should not be
examined further. Additional work is required to examine the weed control spectrum of each herbicide, as it relates to
the development of borage as a crop in New Brunswick.
