Blackleg spots can be found on canola foliage.
Remember to collect samples or notify someone from MAFRD if you are noticing cereal leaf beetle in cereal crops. Levels are quite low in Manitoba, however we are doing a release of a parasitoid that is very effective at keeping cereal leaf beetle at low levels. The samples of larvae will be sent to AAFC in Lethbridge, where they will be examined for parasitoids. Areas of Manitoba where larvae are present but not already containing parasitoids will be given priority for parasitoid releases.
