The first year Nick Hedden started helping growers manage water hemp was 2016. It hasn’t taken long for a variety of products to lose their effectiveness.

“It’s definitely been a challenge,” says Hedden, who is an agronomist with Pioneer in Western Indiana. “Water hemp has between 6-8 chemical class resistances. We’ve got to be thorough, and have a good action plan for 20205 water hemp management.” 

During this episode of the Pioneer Indiana Agronomy Podcast, Hedden talks with hosts Carl Joern and Brian Shrader. 

Hededen’s advice is to have multiple, very strong modes of action. There is no silver bullet, but there are some new options.  He recommends starting with an excellent pre-emergence product to control water hemp before it breaks through the ground.

“After emergence, we are seeing effectiveness with Enlist and Liberty mixed,” Hedden says. “This is what I’d recommend if you’ve got some really heavy water hemp pressure.”

Corteva also has a new product called Kyber® Pro that could be effective.
