ABSTRACT
Seed yield and seed quality of winter canola can be reduced by broadleaf and grass weeds that emerge and grow during the spring. The overall objective of this study was to assess the ability of registered, selective herbicides to control problematic weeds that can occur in New Mexico canola fields during the spring, after winter canola resumes growth. To accomplish this objective, a field study was conducted to determine the abilities of clopyralid to control broadleaf weeds and sethoxydim to control grass weeds. Results from the study suggest that clopyralid at both 0.105 and 0.210 kg active ingredient (ai) ha-1 was unable to control Brassicaceae weeds (flixweed [Descurainia
sophia] and western tansymustard [Descurainia pinnata]). Sethoxydim at 0.210 and 0.525 kg ai ha-1 was able to control volunteer wheat and oat. Neither herbicide caused a significant reduction in canola seed yield, biomass, or harvest index. Combined results suggest grass weeds can be controlled; however, there is a gap in the current chemical catalog to control Brassicaceae weeds in conventional canola.

Canola is a Brassicaceae crop that has recently generated interest from growers in eastern New Mexico due to the opening of a canola seed crushing facility in northwest Texas. Interest in canola is further fueled by the potential
