If you need to spray dicamba soybeans for weeds, you’d better be thinking about finding some different herbicides to use.

The cut off date is June 30 in South Dakota. In North Dakota, the state ag department has extended the cutoff to July 10.

The cutoff is for Engenia, FeXapan and XtendiMax soybeans.

The special needs label in both states says that you can use these products only until soybeans reach the R1 growth stage, 45 days after planting or June 30, whichever comes first.

“While the weather has had an impact on planting this year, which I know is frustrating for many producers, the fact remains that warmer conditions in July increase the risk of volatility and drift when using dicamba products. The cutoff date is based on data which supports increased risk of drift after July 1,” according to a statement from South Dakota Secretary of Agriculture Kim Vanneman. “I encourage producers to explore the other products available to them once the cutoff date for use of dicamba has passed.”
