BROOKINGS, S.D. – Aphids in winter wheat have been reported in Hand County in central South Dakota as well as Hanson, Davidson, and Aurora Counties in the southern portion of the state.
“The warm fall weather is likely the culprit,” Szczepaniec said, encouraging wheat growers to scout emerged winter wheat fields for aphids. “Warm temperatures are forecasted to persist for several more days and aphids are more likely to increase in numbers in these conditions.”
She explained that aphids can survive in whorls of wheat plants for some time when temperatures dip below freezing, but aphid populations will decline quite quickly once nighttime temperatures drop this fall.
