Small Aphid Populations Observed in Wheat
This week we received the first report of aphids in wheat for the 2021 season. The populations won’t be increasing rapidly until the daily temperatures warm up, but it is still a good idea to scout fields and determine if aphids are present.
Alfalfa Weevil Activity Prediction Update: May 20, 2021
This week we accumulated degree days for alfalfa weevils at a rapid rate. As a result, we observed many areas of the state potentially move through more than one larval life stage.
Common Stalk Borer Activity Estimate: May 20, 2021
Warmer weather is finally here. Although we have accumulated quite a few degree days for common stalk borers, nowhere in the state has reached accumulation levels for common stalk borer caterpillar movement into corn fields.
Cabbage White Butterflies Are Here!
Keep an eye out for cabbage white butterflies in your garden. These butterflies lay eggs on the underside of the vegetable leaves. Once the eggs hatch, their caterpillars feed on cabbage, broccoli, Brussel sprouts, cauliflower, kale, turnips and radishes.
Haul the Feed or the Cows
Reduction in pasture forage availability may require producers to decide between hauling feed or hauling cows. Learn how to decide which option is best for your operation.
Seedcorn Maggot Degree Day Activity Estimates: May 20, 2021
Seedcorn maggots can be an early-season pest of corn and soybean in South Dakota, typically affecting crops that are emerging or have recently emerged. Seedcorn maggots can cause direct loss by destroying planted seeds.
SDSU Extension to Host Summer Farm Stress Series

South Dakota State University Extension is launching additional virtual farm stress workshops to promote mental health awareness from May throughout the summer.
Wireworms in the Garden
With warming soil temperatures, overwintering wireworms have become active throughout South Dakota. Wireworms are soil-dwelling insects that can be pests of germinating seeds, seedlings and root crops.
Using Data for Better Seed Selection
As harvest wraps up across the region, winter preparation and planning for next year begins. Yield trial results are a key component when making sound seed selection decisions.
Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity and Diversity in the Field
Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.
