There are limited options for management of root weevils in berry crops. No successful monitoring program has been developed and there are few chemical options. Root weevils are causing damage at an increasing number of locations in Ontario and losses can be devastating in infested fields. A team of researchers across Canada is currently studying the situation in several provinces, in an attempt to develop IPM strategies for monitoring and control of this pest. Meanwhile, growers need immediate options. Beneficial nematodes are commercially available, although very expensive (ie $400-$600 per acre). Application conditions are very specific and control has been very sporadic in the past. A new strain of nematode has recently become available in Ontario, which is more cold tolerant and perhaps better suited for our conditions.
