Extension specialist responds to dicamba concerns

Lincoln, NE— Nebraska crop producers are joining others across the country in facing potential issues related to dicamba, a herbicide for broadleaf weed control.

While the product has been available for a number of years, this was the first year that dicamba-tolerant Roundup Ready 2 Xtend soybean and new dicamba-based formulations were made commercially available in Nebraska.

An estimated 500,000 acres of dicamba-tolerant soybean were planted this year across the state, but broadleaf crops sensitive to the herbicide are raising concerns for growers.

Amit Jhala, Nebraska Extension weed management specialist, has been responding to those concerns. “Several dicamba-sensitive crops are planted in Nebraska, so it’s important for producers to be familiar with dicamba injury symptoms,” Jhala said. “Some of the soybean fields I have visited this season have had symptoms similar to those caused by dicamba, from one end to the other, suggesting off-target movement through volatility.”
