Morrisville, NC – Nufarm announced the registration of Weedar XHL and WeedMaster XHL herbicides powered by its patented 2,4-D Dual Salt Technology to deliver substantial advantages to growers across a range of applications.

Nufarm Dual Salt Technology enables multiple formulation advantages compared to other 2,4-D amines, including a higher concentration of active ingredient to cover 37 percent more acres with every gallon for Weedar XHL and 20 percent more acres for dual-active WeedMaster XHL.

Building on decades of proven results, the new formulations offer low volatility and low odor, plus excellent formulation stability in cold temperatures and tank mixing compatibility with a range of partner products, including K-salt glyphosate.

“To better help growers, we took two proven herbicides and made them better closing a gap on the years it takes to bring new solutions to market,” said Dan Beran, Ph.D., Nufarm Director of Technical Services – Ag US. “With slim margins, growers rely on inputs they know work in their fields. With XHL technology, they can count on Weedar XHL and WeedMaster XHL to perform as before with the added benefits of getting more acres out of every jug.”

Weedar XHL is labeled for more than 25 crops including cereals, corn, soybeans, fallow, pastures and rangeland. Growers moving to Weedar XHL gain more flexible application options with a 7-day preplant interval on corn and soybeans.

New and improved WeedMaster XHL delivers a powerful combination of dual-salt 2,4-D and high quality DGA dicamba for lower volatility (compared to traditional DMA dicamba) and the control of more than 90 types of weeds and brush.

“Dual Salt Technology brings efficiency with proven performance,” said Beran. “Growers want to put their input dollars into products that they know will have a good return on investment. Weedar XHL and WeedMaster XHL with help them do just that.”
