Difference between grazon and grazon next
Control Methods
As summer approaches, many weeds will become more evident in forage pastures and hayfields. At that time of year, the majority of cool-season species have matured, and their declining vegetation is giving way to new broadleaves and grasses of the warmer months. If a producer thinks that it is too late for weed control, they shouldn’t worry. They may be right on time.
Regarding weed management practices, many producers may have heard the sayings “start clean and stay clean” or “control weeds when they’re small and actively growing.” While these are accurate statements, they often refer to annual weeds in row crop agriculture or certain forage systems. Producers should think a bit differently about perennial weed species that are found in established forages. Perennial weeds reproduce by both seed and roots. The following information focuses mainly on perennial broadleaf weeds like dogfennel or cedarweed (figure 1), Carolina horsenettle, goldenrod (figure 2), and tall ironweed (figure 3). Each of these often survive the winter because of their thick underground roots or rhizomes and emerge each spring with ample energy from stored carbohydrates.
Pasture and Forage Minute: Selecting the Right Herbicide, Irrigating Alfalfa and Poison Hemlock
What’s in a Name
By Ben Beckman
One tool that can be used to great effect when controlling weedy plants is an herbicide application. To get good control, we must be sure we have the right product to address the weed we want to manage. Proper weed identification is critical for this first step, but herbicide trade names don’t help make this pairing any easier.
For example, let’s look at a popular pasture herbicide — Grazon P+D. Grazon P+D is a picloram and 2,4-D mixture with a wide spectrum of broadleaf control in pasture settings that was especially liked for its action against leafy spurge. Currently discontinued by the original manufacturer, there are other picloram/2,4-D generics that producers can find and use. Don’t worry — if you still have some Grazon P+D on hand, you can use that up, too.
Now this is where things get a bit confusing. About the time Grazon P+D was phasing out, another herbicide hit the market — Grazon Next HL. This Corteva product, despite a similar name, is a Milestone/2,4-D mix that doesn’t control leafy spurge. It does, however, have great action
Pasture Pro vs Grazon Next
On my 20 acres I use Trimec and CoRoN --Trimec is a broad leaf herbicide that will kill your buttercups but not affect your grasses. CoRoN is a fertilizer. I mix them together and act a one pass spray of my pastures each May. I’ve been doing that for 10 years or so. I also do our lawn. We possess no weeds. No weeds. Did I say we have no weeds? What we do include is beautiful, lush grass. I use a 25 gallon tank sprayer and pull it behind my tractor --but I’ve position the mix into a hand sprayer before to get some places near my hosta beds (do not spray any place near flowers —you’ll kill them all). Both items are readily available at TSC, Farm and Fleet, any farm store. The hardest part about them is the math . . .so much per acre, so many acres, so much water for dilution --my husband figured it out for me one age --now I keep that manuscript handy to refer to. I look forward to May —riding my tractor in the star, spraying my fields, the perceive odor of Trimec . . .oh, check with your vet --not for use where pregnant mares will graze --I only own geldings. Vet said I didn’t have anything to worry about with them, but I maintain them off the pastures for 7 days or until the
Morgantown, KyNever used either one of these. What has worked the best for others? Got some pigweed, ironweed and who knows what else.
Zabcikville, TXI'd go with Chaparral. In my experience it works better with tough weeds. Don't be surprised if it takes awhile to kill, it doesn't work fast, but it works well. I would use 15 gpa of water for plenty of coverage. I used to spray a LOT of Grazon P+D, and like the way it worked. Grazon Next, in my opinion and experience doesn't work nearly as well as PD.
Hopkinsville, Ky.We used chaparral last year had awesome results. I had some fields with locus and it cleaned those up nicely. So about this time last year had some horse nettle, spiny amaranth come in to a different field so sprayed 2oz rate and cleaned it up nicely. With all those weeds gone had crabgrass and other grass thicken in area. One thing it will kill your clover.
Granville County, NCWhen is the best time to use these products? Early in the year...of middle of summer? I have quite a bit of weeds that need killing...I also assume these wont kill grasses like fescue, crabgrass, etc??? Thanks all!
Zabcikville, TXNeither will kill

Pasture Herbicide Update
by Dr. Brent Sellers, University of Florida/IFAS
published in The Florida Cattleman and Livestock Journal
Over the past several years, we have seen advances in the herbicide market for pasture weed control. In fact, things have changed dramatically since tropical soda apple first invaded pastures in south Florida. So, if you’re looking for the silver lining, the invasion of tropical soda apple has actually increased our herbicide options for weed control in pastures. In 2012, and even in late 2011, there are several changes that should be acknowledged.
Velpar. Hopefully, most are aware of the label change this past year. There are no grazing restrictions when applying less than 4.5 pt/A. The haying restriction for Velpar is 38 days when applying less than 4.5 pt/A. Since most of our applications for smutgrass control do not typically exceed 4 pt/A, most should be able to graze pastures immediately after grazing. Be sure that Velpar is only applied during the rainy season as root uptake is essential for smutgrass control.
