South Dakota Grasshopper Prediction for 2023
Grasshoppers can cause serious defoliation in forage, soybeans and corn throughout much of the growing season. See our activity predictions for the 2023 growing season based on the 2022 U.S. Department of Agriculture Adult Grasshopper Survey.
Alfalfa Weevil Activity Prediction Update: May 19, 2023
Forecasted weather conditions are ideal for alfalfa weevil activity, and early detection of feeding activity will prevent extensive defoliation.
Alfalfa Weevil Activity Prediction Update: May 15, 2023
During the last week, the entire state reached enough degree days to have active alfalfa larvae. In areas with the highest accumulation of degree days, alfalfa should be scouted to ensure that alfalfa weevils don’t cause extensive defoliation.
