Extended-residual herbicides offer a better approach for vegetation management
What do you look for in a herbicide? Effectiveness against target weed species? Of course. What about cost? Nobody can blame you there. Ease of handling, use rates, volatility? Absolutely. But what about residual activity? Because if you’re not evaluating the residual activity of your weed control products, you may be costing yourself money, effort and time.
“If you have tens of thousands of acres of right-of-way to manage, you don’t want to see incompatible vegetation popping back up two months after a herbicide application,” said Darrell Russell, market development specialist, with Corteva Agriscience. “You want to make that application, move on to the next job and not worry about it.”
Beyond just minimizing the aggravation factor, using products and methods that offer extended residual control delivers a wide range of environmental, operational and fiscal benefits, including:
- Improved biological control. By suppressing emergence and regrowth of incompatible species, you give native grasses and forbs a chance to become established on rights-of-way or roadside management zones. In turn, these beneficial species can crowd out the incompatibles, reducing the level of management required over time.
- Reduced soil compaction, erosion and habitat disruption. Extended residual control helps reduce traffic from repeat applications on rights-of-way or other vegetation management zones. And if you’re reducing traffic, you’re also reducing compaction, lowering the risk and severity of erosion, and minimizing the impacts of equipment and human traffic on sensitive habitat.
- Improved operational efficiency. Fewer re-applications mean you can deploy labor and assets to higher-priority areas and tasks, improving overall efficiency and reducing the risk of service interruptions from vegetation interference.
- Reduced vegetation management expenses. If you’re not re-treating, you’re not spending valuable budget dollars on the additional fuel, labor and equipment those additional applications demand.
Russell said products such as HighNoon® herbicide, which offer extended residual control of incompatible broadleaf weeds and other species, can help vegetation managers reap the benefits of an Integrated Vegetation Management (IVM) program. At the same time, reduced-risk active ingredients such as Rinskor® active, one of the two actives in HighNoon, mean fewer headaches associated with environmental compliance and resistance management.
“The combination of Rinskor and aminopyralid active ingredients in HighNoon gives vegetation managers real advantages when it comes to broadleaf weed control and even suppression of certain woody species,” Russell said. “First is the residual control; HighNoon offers long-term control of some of the most irritating broadleaf weeds, and even has preemergence activity on susceptible species.
Broad-spectrum weed control with no signal word, minimal PPE
In addition, HighNoon has a very favorable environmental profile. Both actives have been designated by the EPA as reduced-risk herbicides. HighNoon is effective at lower use rates, can be used up to water’s edge and is essentially nonvolatile, so it stays where it’s applied and poses very little risk to nontarget species. Plus, HighNoon carries no signal word and requires minimal personal protective equipments, making it easy to use even for less experienced applicators.
“Finally, HighNoon has demonstrated a much lower rate of resistance development than other herbicide classes like ALS inhibitors or ACCase inhibitors, so vegetation managers and contractors can use HighNoon with confidence,” Russell said.
The bottom line? The extended residual control and reduced-risk profile offered by HighNoon herbicide with Rinskor can help you avoid some of vegetation management’s most prevalent – and most aggravating – pitfalls.
