Various Grasshopper Species Are Active Across South Dakota
While scouting, we have noticed increased grasshopper nymph activity and in some areas these populations are close to threshold levels. Crops in areas that have had high populations should be regularly scouted to ensure that extensive defoliation doesn’t go unnoticed.
Aphid Populations Detected in Wheat
Aphids are present in South Dakota wheat fields, and that means it’s time to start scouting.
Pea Aphid Alert: Forecasted temperatures could result in rapid population increases
The temperatures during the last week and the forecasted temperatures for next week will potentially encourage rapid pea aphid population growth. Although many fields have been cut recently, pea aphids can still readily recolonize alfalfa.
