Alert Details

Soybean aphid development risks remain in the forecast for the next week with Moderate risks focused from eastern South Dakota, far southeast North Dakota southeast into Minnesota, far northern Iowa, and into Wisconsin. Low risks surround the Moderate risk area from the central Dakotas south into northeast Nebraska, northern/central Iowa, far northwest/northern Illinois, and into Wisconsin. Growers located in or near the risk areas should regularly scout soybean fields that are between the R1 and R5.5 growth stages, and make any treatment decisions based on field-level thresholds. Recent cooler than average temperatures may help increase populations in some areas so regular scouting is important until the crop reaches the R5-R5.5 growth stage.
