Winged aphids are still on the move in Iowa, although most fields still remain well below treatment levels. Neighboring states have notable aphids, so scouting should still continue.
Erin Hodgson talks about recent aphid populations and also some interesting defoliators in soybean.
Drs. Matt O'Neal and Erin Hodgson discuss current soybean aphid activity around Iowa and the region. Numbers are remaining low with some regions declining in density. They also discuss upcoming field tours (available at www.aep.iastate.edu).
