To evaluate Group 14 herbicide options in chickpeas when applied alone, or with Balance and Terbyne Xtreme.

For more than 25 years, broadleaf weed control in northern region chickpeas has been heavily reliant on herbicides from just two modes of action; Group 27 eg Balance or Group 5 eg Terbyne Xtreme or Simazine. Recent registrations of Group 14 herbicides (Terrad’or, Terrain, Reflex and Voraxor) for use in pulses has provided new options that may reduce the herbicide resistance selection pressure.

The primary objective of this project was to validate the benefits and fit of the Group 14 herbicides alone or in combination with existing
chemistry to refine weed management strategies in chickpeas. Similar trials were conducted in winter 2022.

In addition, all the evaluated group 14 herbicides have equivalent use patterns in faba beans. Generating sound residual efficacy data in faba beans can be challenging because of the rapid crop development and canopy closure. Instead of duplicating trials in faba beans, 3 extra herbicide treatments, that are ONLY registered in faba beans, were included in the chickpea trials.
