Soybean gall midge is proving to be a very difficult pest for farmers to manage.
Iowa State University Extension entomologist Erin Hodgson says that’s mainly because the larvae that feed on the plant are inside the stem.
“It’s really really hard to manage a pest that we can’t access, and it’s really hard to use contact insecticides to make an impact. And the adults are continuously flying for many weeks out of the growing season.”
She tells Brownfield that complicates the timing of treatments.
