HighNoon™ herbicide profile
HighNoon includes the first new active ingredient (Rinskor® active) available for rangeland and pastures in nearly 15 years. HighNoon combines Rinskor with the active ingredient in Milestone (aminopyralid). Rinskor works by attaching to a new binding site on plants for a new mode of action with some additional benefits in lower use rate, broader spectrum and improved environmental fate. Because it works selectively, HighNoon helps maintain desirable vegetation in the field. This profile makes it a simple – and beneficial – replacement in a lot of rangeland and pasture weed control programs.
If you’re currently using Tordon® 22K herbicide...
If you’re applying Tordon® 22K herbicide, it’s probably because you need serious control of noxious and invasive weeds. HighNoon™ herbicide offers that same level of control on many species, but with a little more flexibility, while going easier on desirable vegetation. While Tordon 22K is safe on grasses, the grass safety profile for HighNoon is actually better — even at 4X labeled rates. This makes HighNoon a good option when there’s overlap in spot treatment, to prevent areas of damage that can then become hospitable to invasives, cheatgrass and weeds.
Although in most cases you won’t need to, you can use Tordon 22K with HighNoon. HighNoon can be tank-mixed with lower rates of Tordon 22K to add a new site of action to your program while maintaining some selectivity to desirable vegetation. HighNoon also gives you more application flexibility. Unlike Tordon 22K, HighNoon can be sprayed up to the water’s edge.
If you’re currently using Milestone® herbicide...
HighNoon™ herbicide starts from a better baseline than Milestone® herbicide. Think of it this way: Anything Milestone can do, HighNoon can do better. With HighNoon, you get a more complete, faster kill thanks to Rinskor® active. That means you get your land back quicker.
Land managers and ranchers are also finding HighNoon is a more cost-effective way to get your aminopyralid on the ground. With a new site of action through Rinskor, HighNoon provides a wider spectrum of control compared to Milestone, so you can use it to control more weeds even with a reduced-risk herbicide. Finally, there are several convenience features for HighNoon versus Milestone. HighNoon comes in a galon container, versus quarts of Milestone, so there’s less packaging to handle when you’re treating large areas. HighNoon also offers more room for error in measuring and spraying at low levels compared to Milestone, where measurements have to be very precise, particularly at the 5-7 oz. levels, or there is risk of damage to desirables.
If you’re currently using Chaparral™ herbicide and/or Opensight® herbicide...
You may be adding Escort XP for additional control with these products. With Chaparral™ and Opensight® herbicides, you’re locked into the ratio of Escort XP you can use. But with HighNoon™ herbicide, you can prescribe the correct rate of Escort XP or Telar you need for your acre.
HighNoon is a liquid, so it’s easier to handle than the granular formulations of Chaparral and Opensight. Rinskor® active in HighNoon increases burndown and early activity versus Chaparral and Opensight, and compared to Milestone® herbicide, HighNoon provides a more complete, faster kill.
If you like adding Plateau and indaziflam for annual grasses...
The most expensive component of weed control is the time it takes to spray. When you use HighNoon™ herbicide along with Plateau or indaziflam, you can control broadleaves and invasive grasses together in the same pass, giving desirable grasses the best chance to compete for the land. This combination application may not need more than two years of control before desirable grasses can out-compete annual grasses.
Because there is no way to know what broadleaves could be in the seedbank until the following year, getting them under control proactively is important. The same is true with desirable grasses: You don’t know what’s there if they have not been released. Using a short residual product mix first (like Plateau plus HighNoon), or HighNoon alone in the spring, can protect desirables while knocking out broadleaves.
Using HighNoon also allows you to introduce more modes and sites of action, which is especially helpful when combating multiple flushes of annual grasses at various growth stages through the season. HighNoon has activity at pre-germination and boot/infloresence, while Plataeau’s activity is mostly post-germination. Indaziflam is only pre-germination on annuals.
In non-crop areas, HighNoon can be used at a rate of up to 40 fl oz per acre for effective and lasting control. This is especially useful and efficient when you need to keep areas like roadsides, ditches, rights-of-way, industrial sites and more clear of unsightly and troublesome weeds and vegetation.
The land is always going to present new challenges. A tool like HighNoon, with new site of action and more flexible options for combinations and application, can help you stay a step ahead of weeds while promoting desirable vegetation. With better control and convenience, it may be worth exploring HighNoon as an option in your program.
