11 May Glyphosate-resistant kochia control in spring wheat

Posted at 16:54h in Weeds

The most effective and consistent treatments for glyphosate-resistant (GR) kochia management included Authority (sulfentrazone) applied pre-emergence, post-emergent Enforcer D (fluroxypyr/bromoxynil/2,4-D) at the high label rate, and post-emergent Infinity (pyrasulfotole/bromoxynil). Glyphosate-resistant (Group 9) kochia has rapidly spread across Alberta since it was first discovered in 2011 in...

03 Mar Trends in global herbicide resistance management

Posted at 21:31h in Weeds

Trends in herbicide resistance management over the past decade were identified and include renewed efforts by the agrichemical industry in herbicide discovery, cultivation of crops with combined (stacked) HR traits, increasing reliance on pre-emergence vs. post-emergence herbicides, breeding for weed-competitive crop cultivars, expansion of harvest...
