In his weekly Call of the Land interview, Alberta Agriculture pest specialist Scott Meers says there is an "outbreak situation" for bertha armyworm in central Alberta and some counties in southern Alberta.
He recommends scouting for the worms by shaking the plants and counting the worms on the ground in a quarter square metre area, and multiplying by four.
Meers also says there is some spraying for high numbers of lygus bugs in the southwest, specifically Vulcan, Foothills, Mountainview and Rockyview counties.
