Black cutworm moths moving north
Crop pests are on the move.
University of Minnesota Extension integrated pest management specialist Bruce Potter says it’s common for certain insects to migrate north this time of year.
“Things like army worm and black cutworm, we’ve got a good network of cooperators out there (scouting).”
He tells Brownfield extensive scouting this spring showed low black cutworm moth counts.
“But that kind of changed starting the sixth of May. We got a flight into some areas, some again last week. And my guess is this weekend brought more moths with it on some of these weather systems coming out of the south.”
Potter says the advanced planting progress is good because cutworm moths prefer untilled fields so they can lay eggs in growing vegetation.
