Science Edition 2021—Key result: This study validates a new threshold for lygus in canola. The general pattern is that abundances below two lygus per sweep do not reduce yield. Thus, the threshold of two to three lygus per sweep (20-30 per 10 sweeps) is recommended. Because current canola cultivars appear to tolerate lygus damage better than older...

Science Edition 2021—Key result: Non-crop areas within or near to fields can serve as a source and a destination for beneficial insects at different times of the season. A correlational study of 60 million seeded acres of yield data obtained from Agricultural Financial Services Corporation (AFSC) showed that counties in Alberta where fields tend to contain more...

Science Edition 2021—Key result: Effective herbicides remain a critical part of integrated weed management. Steps taken now to increase diversity in the management strategy, while herbicides are still effective, is crucial to maintaining control of weed populations in the long term. Herbicide resistance is increasing in Western Canada and around the world. While herbicides are still mostly...
