Leafy spurge has germinated and is growing rapidly in South Dakota: Scout carefully!

Leafy spurge can reduce the value and productivity of pasture and displace desirable vegetation. Now is the time to scout for infestations to determine which management tactics will be most effective.

South Dakota Grasshopper Prediction for 2025

In 2025, it is likely that grasshopper populations will once again reach levels capable of causing issues in some areas of the state. Scouting should begin shortly after planting in areas where they were problematic in 2024 and continue throughout the growing season.

Black Grass Bug Activity Ramping Up

Black grass bugs feed on fresh green growth, which can result in stunted plants and decreased forage quality. Monitoring and potential management of black grass bugs will be of increased importance this spring, especially if drought persists.

Traditionally, the prairie is home to herbaceous vegetation, such as grasses and broadleaf plant species. Although many woody plants are naturally present in canyon, riparian, or river areas, they are not meant to be a part of the grassland landscape.
