Alberta swede midge survey results
By Alberta Agriculture and Forestry
In late July, Alberta Agriculture and Forestry (AF) staff surveyed 42 canola sites in central Alberta and detected very low density swede midge larvae.
“At each site, racemes (flowering stalks) on canola plants were assessed for typical bell damage to the flowers,” AF quoted Scott Meers, insect management specialist at AF in Brooks, Alta., as saying. “These flowers were then dissected, either in the field or later in the laboratory, to confirm whether or not swede midge larvae were present.”
Results of the survey are available here.
