Stop the spread of Kochia
Kochia that survived pre-seed burnoff needs to be taken out before it drops seed later in the season. The big weeds can produce at least 15,000 seeds per plant – often many more – so letting them set seed and then spreading that seed with the combine can move a herbicide-resistant population across a field very quickly.
Kochia with resistance to both Group 2 and Group 9 herbicides is found all across the Prairies in big numbers. Agriculture and Agri-Food Canada weed scientists have also confirmed kochia populations with resistance to Group 4 and Group 14 herbicides.
