Is there a resource for identifying weeds in CRP acres?

Our online Weed and Brush Guide is a good place to start. This easy-to-use guide will help you identify individual weeds and brush species and will offer you tips and steps for effective treatment. If you need further assistance, contact an agronomist with your local ag chem dealer or your county Extension agent. Your local Dow AgroSciences sales representative is another excellent resource. Find your local specialist by contacting us.

What is the best time of year for herbicide applications?

Since CRP acres typically contain a mix of weeds and brush, a general recommendation is to treat weeds while they are actively growing and treat unwanted brush and trees once they have fully leafed out but while conditions are still favorable for growth. Fall is an excellent time to treat knapweed, biennial thistles, such as musk or plumeless thistle; and perennial weeds, including Canada thistle and leafy spurge. Applications made during drought stress or other conditions preventing active growth may not provide acceptable control. You can find more specific treatment timing recommendations on the product specimen label.

Isn’t mowing cheaper than chemical weed control?

No. While herbicide treatments vary depending on product, rate applied and application method, our Range & Pasture products offer longer-lasting, more complete results than mechanical control methods. According to Texas A&M University research, mowing costs $12 to $14 per acre per trip — with two trips needed annually on average. Even then, you’re only giving weeds a haircut. Regrowth occurs quickly. Mowing or shredding also carries hidden costs. Frequent mowing can weaken grass stands, open sod cover and increase weed populations. Mechanical control also can leave ruts, damage turf and increase soil erosion.

Why is aminopyralid so useful in CRP weed control?

Aminopyralid, an active ingredient in Milestone® and ForeFront R&P herbicides, is highly active on many noxious, invasive and other tough broadleaf weeds in CRP land. Factors including control spectrum, thorough translocation and residual activity make it extremely effective. Removing competition from weeds releases grass production. Always use herbicide treatments in conjunction with an overall weed management plan.

What if CRP land is opened to grazing or haying due to drought? Are there any grazing restrictions for Dow AgroSciences Range & Pasture products?

For most livestock species, including beef, cattle, sheep, horses and goats, our Range & Pasture products carry no grazing restrictions, even during or immediately after application. However, there are grazing restrictions for lactating dairy animals. Consult individual product specimen labels for specific grazing and haying restrictions prior to application.

Which Dow AgroSciences Range & Pasture products require a license to purchase and/or apply?

Licensing requirements vary by state. However, Grazon® P+D, Surmount and Tordon® 22K herbicides are federally Restricted Use Pesticides. Thus, Grazon P+D, Surmount and Tordon 22K require a license to sell, purchase and make applications. Contact your state department of agriculture or your county Extension agent for local requirements.

How do I acquire a permit to purchase and apply restricted-use herbicides?

Each state has specific regulations regarding applying herbicides. Contact your state licensing board, your county Extension office or your state department of agriculture for certification and licensing requirements.

What is the shelf-life of Dow AgroSciences Range & Pasture herbicide products?

As long as the seal on the container is unbroken, the efficacy is almost indefinite. If the seal is broken, it may be subject to some evaporation or volatilization over several years. But practically speaking, we’ve never seen a problem with the efficacy of our Range & Pasture herbicides because of the age of the container. If the product has been mixed with water, there may be some settling out of ingredients over time. Be sure to agitate the mix before you spray.

How much do Dow AgroSciences Range & Pasture products cost?

Selection, availability and pricing vary by retail dealer. Call or visit your local ag chemical dealer for product availability and pricing. Keep in mind that price does not necessarily equal value. Considerations, such as use rates, spectrum of control, residual activity, ease of use and grass tolerance, all help determine a product’s true value and your return on investment.
