Field scouting is critical because it enables the identification of potential risks to crops. Canola production systems across the Canadian prairies will suffer insect pest outbreaks. However, the identification of these insect pests PLUS the application of established monitoring methods will enable growers to make informed pest management decisions.
We first offered the chart below in 2015 but we again post our generalized canola scouting chart to aid in-field scouting on the Canadian prairies. Two versions are below – the first version contains hyperlinks to help growers learn more about some of our insect pests and how to monitor while the second version may be easier to view or print.
Whenever possible, monitor and compare to established economic thresholds so pollinators and beneficial arthropods are preserved. Economic thresholds, by definition, can help growers avoid crop losses due to an insect pest.
Good luck with the growing season!
