In his weekly Call of the Land radio interview, Alberta Agriculture pest specialist Scott Meers says that bertha armyworm counts are “Enough to get a little bit concerned about, with some sites at “the first level of warning.”
Meers has posted a video on how to scout for berthas.
Meers said that in two to three weeks, depending on heat and other conditions, it is likely that some fields will need to be sprayed. The outbreak is not expected to as bad as last year, but it will likely be more spotty and over a wider area, Meers said.
Grasshopper activity is “not too extreme,” Meers said, with outbreaks in Two Hills County and in the Peace Region north of Manning to High Level.
The wheat midge threat has ended in the south but Meers recommends scouting in central Alberta.
