Soybean aphid populations have remained relatively low across much of Minnesota, but University of Minnesota Extension Crops Educator Liz Stahl says growers should continue monitoring fields as temperatures moderate. “Overall numbers have been low. I know there has been some isolated fields where people have reached threshold,” Stahl said. “This hot weather we had, I think, was really slowing things down because like us, aphids don’t like really hot weather.” The more moderate temps we’ve seen favor reproductive rates for soybean aphids.”
