Cereal crops in rotation provide canola growers with another opportunity to control cleavers, volunteer canola and other tough weeds to reduce the threat to next year’s canola.
If you have cleavers in a field, remember than many cleavers have group-2 resistance. If using a group-2 product in cereals, consider a tank mix with an effective cleavers herbicide from another group.
Volunteer canola control limits clubroot build up. Growers in the clubroot zone need to control volunteer canola in non-canola crops. Volunteer canola provides clubroot a bridge for spore buildup and limits the effectiveness of the non-canola years in rotation to reduce the clubroot threat. This same practice also works for blackleg management.
