Xtend soybeans expand options, but be dicamba-drift aware
Reading Time: 4 minutes New dicamba- and glyphosate-tolerant soybeans offer more weed control options and are another tool to address herbicide-tolerant weeds, but farmers need to take steps to avoid dicamba drift and spray tank residue, Manitoba officials say.

Pest Patrol: Keeping woodsorrel under control
#PestPatrol with Mike Cowbrough, OMAFRA
Reading Time: 2 minutes A grower I work with is seeing more woodsorrel in corn and soybean fields. I can’t seem to find much information on how to control this weed. Any suggestions?
