"Halex GT stands out as a product for resistance management because of its multiple modes of action, which is what growers should look for when creating a resistance management program against different weeds. I’m very happy with Halex GT."
"We applied a post-emergence application of Halex GT to corn that was six inches tall. After application, there weren’t any weeds in our field. I’m very happy with Halex GT. It does an incredible job each year, so we continue to use it."
"Halex GT is a great product that controls our problem weeds and doesn’t damage the crop. Our toughest weeds are velvetleaf and waterhemp. Halex GT controls those weeds very well. With Halex GT, we have season-long residual control and a clean field at the end of the season. If my neighbor asked me what I thought of Halex GT, I would tell him if you haven’t used it, you’re missing out on a very good product."
"Halex GT has done a great job against our most problematic weeds so that growers can have a timely harvest without having weeds as a major issue. Most growers use this herbicide because of its versatility, and it’s hugely important to have multiple modes of action to help control these tough resistant weeds. Halex GT works. If my customers ask me about Halex GT, I would recommend that they look at it. It’s a quality product. It does the job."
