Cutworm feeding results in notched, wilted, dead or cut-off plants. Patches of missing plants could also be cutworms. Include cutworms on the scouting checklist for the first one to three weeks after emergence… -
Jim Tansey and Keith Gabert talk about flea beetles – including how far they travel to find the first canola crops, major differences between striped and crucifer species, and how long the risk can last…
