Wireworm
With information from Dr. Hector Carcamo and Haley Catton AAFC research scientists.
Dr. Haley Catton a Cereal Crop Entomology scientist and researcher points out that wireworm is a chronic pest in Canada and native to Alberta's grasslands. They seem to prefer grain crops, but will attack most crops.
As she mentions in the video, research is behind on wireworm and she aims to answer many of the questions farmers may have now that an effective seed treatment can disrupt its lifecycle to allow a crop to mature.
"Know the history of dead patches in your fields," she said. If you see a dead patch, dig at the edges of the patch and look for wireworms. "If you find them, use treated seed in those areas."
There's a national network working on wireworm through AAFC. Every region has their own species to research.
