Consider herbicide carryover before seeding

Many growers decided to increase their canola acres this year. Other growers may decide to keep the same acres, but will be juggling fields at the last minute. In either case, canola is often going on fields not planned for canola when growers did their herbicide applications last year.

This could raise some issues with herbicide carryover. Canola going on to pulse stubble, for example, raises the possibility of imazethapyr carryover. See below for the complete list of residual herbicides and the carryover considerations for each.
