New Herbicide-Tolerant Traits Could Boost Sorghum’s Rotational Benefits

Sorghum can be a great rotational crop option. It’s well suited to marginal soils, less drought-sensitive than corn, and can allow growers to break up continuous soybean rotations, shade out weeds, and use different herbicide modes of action, says Virginia Tech weed specialist Dr. Michael Flessner.

But grass weed control has long plagued the growers who favor this hardy crop, since sorghum is also a grass species. 

That’s why the three new herbicide-tolerant (non-GMO) traits entering the market are a welcome development for growers. They can expand sorghum postemergence grass weed control options, which may encourage more growers to add this crop to the mix and take advantage of its rotational benefits, Dr. Flessner says.
