As winter canola acreage increases in Washington State, the cabbage seedpod weevil is becoming a problem. In addition to canola, this tiny weevil can also feed on flixweed, tansy mustard, and whitetop. If left unmanaged, the pest can damage ripening canola seeds enough to impact overall yields by as much as 50%. This publication describes the cabbage seedpod weevil, its lifecycle, and damage it incurs. It also outlines how to determine if the pest is a problem in your fields and recommendations for management.
