Kale root maggot (appearing end of June in southern Alberta)
Kale
South/Central Alberta
Noticed my kale plants starting to wilt. Variety is blue curled and all were healthy up til yesterday (about 2-3 weeks after setting out) Lifting a plant out of the earth shows several small white grubs (one third to one half size of a rice kernel) burrowing into the main root stem. No visible sign of activity above ground level. How can I get rid of or at least control these things. BT probably won't touch them as they seem to be only below grade and are attracted to the roots.
Many thanks in advance for any assistance - Robert in Southern Alberta

It will be helpful if you upload images of damaged plants and grubs. Thanks almost 7 years ago.
