Final Words of Caution on Wheat Midge
Now is an important time to do some evening scouting and become aware of any activity in your fields. Find out now . . . Not at harvest time!
Dr. Ian MacRae, extension entomologist based in Crookston, reported finding only a few adult midge flying over the weekend. However, the peak emergence is still a few days away. Though populations are generally small in the region, localized hot spots are very possible. We have seen these populations increase rapidly under favorable conditions before. Having a high percent of the crop heading when females are laying eggs is risky and justifies field scouting to determine whether insecticide treatment is warranted.
