Crop Tolerance to Soil Herbicide Residual

Some herbicides can persist in soil, especially dry soil. Herbicide carryover could be an issue in 2021 across the state depending upon last year’s moisture levels and field conditions.

Black Grass Bug Activity Expected in Coming Weeks

Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.

Water Use by Plant Stage

Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.

June 2019 Climate Outlook for South Dakota

As South Dakota emerges from the wettest 12-month period in 124 years of climate recordkeeping (June 2018-May 2019), June has started warmer and drier than average. The outlook, however, turns towards cooler and wetter than average again for the middle of the month.

South Dakota Land Use Trends (2012-2017)

Significant education efforts for natural resource conservation have occurred in South Dakota during the last five years. Many stakeholder groups have brought awareness for soil health and water quality to the forefront.

Be on the Lookout for Black Grass Bugs

It’s time to begin scouting pasture and wheat for the presence of black grass bugs. Last year, we saw the highest populations in areas of Central and Southwestern South Dakota. If left untreated, black grass bug populations tend to increase year after year.

July 2019 Climate Outlook: Challenges Continue

This year’s seasonal pattern of wetter than average conditions is projected to continue through July and the rest of the summer season. The latest climate outlook, released June 20, 2019, shows an increased chance of wetter than average conditions in the next one to three months for the state of South Dakota.
