Corteva Announces Expanded Label for HighNoon® Herbicide

Reduced-Risk Product Gives Vegetation Managers Nationwide Easy-to-Use Control of Troublesome Weeds and Grasses 

INDIANAPOLIS – Corteva, a leader in the development of reduced-risk products for weed and insect control, announces the nationwide availability of HighNoon® herbicide. HighNoon offers utility and roadside vegetation managers and applicators a flexible, easy-to-use, reduced-risk liquid option for control of over 140 troublesome broadleaf weeds and annual grasses, and provides a valuable option for tank-mixing to enhance control of certain woody species.

“HighNoon offers an unmatched combination of use site flexibility, safety on desirable grasses and forbes, and an extensive weed control spectrum,” says Jill Zeller, portfolio marketing leader, Corteva. “That’s why we’re so excited to introduce HighNoon nationally – we know it works, and we have years of experience with HighNoon in managed lands in the West to back that up.”

A Product the Industry
Can Trust

HighNoon combines two powerful active ingredients, Rinskor® and aminopyralid, to provide selective activity that helps maintain desirable grasses and forbs while controlling some of the vegetation manager’s most troublesome weeds like annual and biannual thistles, poison hemlock and wild parsnip. In addition, HighNoon has no signal word thus it offers safer handling.”

“HighNoon offers excellent flexibility and low odor,” says Will Hatler, field scientist, Corteva. “It can be used up to water’s edge, and for those who spray sites close to pastures, HighNoon has no grazing restrictions. Add the fact that Rinskor earned the Green Chemistry Challenge Award from the American Chemical Society’s Green Chemistry Institute, and you have added assurance this product has a lighter environmental footprint and is a good option for public spaces.”

Trusted Strength for Crucial Times – Protecting the Land, Investments and Future

HighNoon gives vegetation managers an easy-to-use liquid formulation that mixes well with other products to offer extended broadleaf weed control, along with control of troublesome woody species like salt cedar and Russian olive and so many others.

“All of this is in addition to an exceptional level of weed control,” Hatler says. “It makes HighNoon the perfect foundation product for vegetation management.”

“At the end of the day, utility and roadside vegetation managers need to be able to trust the products they and their contractors use,” Zeller says. “HighNoon enables that trust through enhanced activity on some of the most problematic weeds, a reduced risk profile and overall ease of use.”
