Soybean aphid pressure intensifying
Soybean aphid infestations are surging throughout the Upper Midwest.
Syngenta agronomic services rep Jesse Grote says populations are growing fast.
“Especially up in northern Iowa. So it’s prime time to be scouting for aphids, and that needs to be done on a seven to ten-day interval here at least through the month of August.”
He tells Brownfield the economic threshold is 250 aphids per plant.
“Then we need to get an insecticide like Endigo ZCX out there and get some good knockdown and residual control.”
University of Minnesota Extension integrated pest management specialist Bruce Potter recently told Brownfield soybean aphid numbers have been rapidly rising in southern Minnesota as well.
