Key result: The current system for monitoring potential bertha armyworm outbreaks is based on a pheromone trap network developed in the 1970s (Steck et al. 1979) and improved in the 1980s (Struble et al. 1984). This study tested the efficiency of this system in the context of current canola production and determined the monitoring and...

Key Result: Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is commonly managed by routine application of fungicides, typically without any indication of disease risk. Through this study, a quantitative polymerase chain reaction (qPCR)-based assay was developed to measure S. sclerotiorum DNA in canola petals, enabling rapid and accurate estimates of infestation levels when timely fungicide...
