Manitoba Insect & Disease Update – Issue 2: May 25, 2016

The Manitoba Insect and Disease Update for this week is now posted at:


Insects: Cutworms and flea beetles on canola are the insects of greatest concern currently. Seed treatments should still be effective against flea beetles in most canola fields, although scouting for feeding damage is encouraged, especially in the earlier seeded fields where seed treatments may soon start losing effectiveness. Cutworm levels are quite variable, hard to find in some fields, more noticeable in others. So scout for potential cutworm feeding on emerging plants and dig for the larvae if you find an area that is showing signs of cutworm feeding.

Plant Pathogens: Scouting for stripe rust in wheat and seedling diseases in emerging crops will be important.
