Canola swede midge damage: now what?
By Ontario Canola Growers
July 16, 2013, Ontario – Growers are seeing damage to canola from swede midge and may be trying to decide on the best course of action. This is not an easy decision, or one that we have a lot of experience with. The ability of a canola field to recover and produce a marketable yield will depend what percentage of plants are affected, the growth stage of canola and how severe the damage is. In most fields, canola plants will be at various stages, which is a good thing, because neighbouring plants can partially compensate for other severely damaged plants.
In some cases it will still be economical to try and control the midge so the canola can bolt and produce reasonable yield. The photos and guidelines from Ontario Canola Growers will help you stage your crop, assess the degree of damage and decide on course of action. | READ MORE
