Dicamba-Resistant Kochia Can Likely Be Found Across South Dakota

Kochia populations collected across South Dakota have been subjected to an herbicide effectiveness screen, where a treatment of dicamba was applied and some kochia plants exhibited survival and regrowth after treatment.

Understanding Hay Inoculants and Preservatives on ‘Dry’ Hay

As haying season approaches, producers across South Dakota will begin preparing to get out the baler. In recent years, it has been quite difficult for many producers to put up quality, dry hay. This often results in growers considering using inoculants and hay preservatives.

National Sunflower Association 2021 Sunflower Survey

Volunteers from private industry and SDSU Extension will soon be visiting South Dakota sunflower fields to participate in the biennial sunflower survey. The survey aims to evaluate yields and production practices along with pest pressure from weeds, insects, diseases and birds.

Temperature and Herbicide Performance

In South Dakota, the spring can come with a wide range of temperature fluctuations. This will affect the performance of burndown herbicides. Depending upon the target weed, type of herbicide and application rate, there will likely be decreased weed control in cooler temperatures.

Overlapping Residual Herbicides May Be Necessary for Effective Weed Management

Weed management in sunflowers poses unique challenges. Compared with many other crops, there is a limited number of herbicides selections, especially postemergence herbicides.

Grassy Weeds

Grassy weeds are a problem in all field crops. They must be identified at early stages of growth so they can be controlled before crop yields are seriously threatened. Control measures are not the same for all grassy weeds, so accurate seedling identification is important.
