Key result: This study continued work initiated by earlier research which showed that parasitism of diamondback moth larvae and pupae can be relatively high early in the season. Canola producers are encouraged to carefully monitor populations, waiting a few days after nominal thresholds are reached to provide beneficial insects an opportunity to control larvae and...

Key Result: Researchers were able to develop and validate nine real-time qPCR assays targeting eight different phytoplasma (aster yellows) species along with P. brassicae (clubroot) and L. maculans (blackleg). This project provides tools for producers and regulators to obtain timely information on plant disease prevalence and spread, which will aid efforts to contain and control...

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...
