As canola acres increase, lygus is becoming a more perennial pest. Without solid economic thresholds, there is an increased environmental footprint when managing Lygus due to the use of insecticides.
Validate thresholds by assessing lygus feeding on key canola cultivars and compare their responses to feeding starting at the bud stage.
The current economic threshold for lygus at 1 per sweep is too low. Depending on environmental conditions (heat and moisture), 2-3 lygus per sweep is more likely correct.
Reassessing the economic threshold for Lygus bugs on herbicide-tolerant canola cultivars, growers can decrease their environmental footprint while reducing the cost of production and maintaining high yields.
