Early lygus bug pressure is reported in the Peace and in central Alberta near Penhold. CCC’s Peace region agronomy specialist Erin Brock has reports of 3-4 lygus bugs per bud cluster in some fields. There are no economic thresholds for lygus bug on canola at the bud stage. This early feeding is a concern but caution is advised as the canola staging is still early and recovery can be good if damage is minimal. Presence of lugus bugs is not enough to trigger a spray operation. Scout fields to observe the extent of the damage. At this point in time, populations are low and canola can compensate for the initial damage.
