Evaluating a new soybean seed treatment to control Sudden Death Syndrome in Kansas

Sudden Death Syndrome (SDS) is a disease that affects soybeans and is caused by a soilborne fungus. Since there are no varieties that offer full resistance, seed treatments are a common management practice. Read about a recent K-State study evaluating a new product for the 2020 growing season.

Considerations for applications of over-the-top dicamba formulations

It is that time of year again for post-emergent applications of Engenia, Fexapan, and Xtendimax on dicamba-resistant soybeans. In light of the recent court ruling, it is vital that application restrictions are followed closely to prevent non-target dicamba injury to conventional, Enlist, and Liberty Link soybeans.
