Low numbers of soybean aphids are being found in the region. University of Minnesota Extension Entomologist Ian MacRae says it’s a good idea to begin scouting. “We’re starting to see some aphids mostly down in west central Minnesota. I haven’t seen that many up here. There are a couple of plants I’ve seen here and there, but when we start seeing aphids show up it’s always a good idea to start counting, keeping on top of the population.” MacRae says insecticide resistance is becoming an issue for aphid management and urges farmers to follow threshold guidelines.
