Integrated Pest Management Options

New pest of canola in Ontario. Under heavy midge infestations, later-planted spring canola plants may experience stunting and malformed growth, with extremely reduced flower and pod formation. Thresholds and spray timing are not available at this time. For more information on this pest, see the OMAFRA Publication 811, Agronomy Guide for Field Crops, for further information on pest biology and management options.
