AminopyralidAminopyralid

Solutions Pest & Lawn is home to many different herbicides which contain active ingredients designed to remove the toughest of weeds. One such active ingredient that is particularly notable is the new age herbicide known as aminopyralid. Aminopyralid is regarded as a “next generation” herbicide and was developed to control noxious, poisonous and invasive broadleaf weeds for agricultural farmers and residential customers.

Solutions Pest & Lawn is happy to carry herbicides which contain aminopyralid. On this page you can learn some interesting facts about this herbicide, it’s history and how it works as well as shop our line of aminopyralid-based products.

What Is Aminopyralid?

Aminopyralid (4-amino-3,6-dichloro-2-pyridine carboxylic acid) is a pyridine carboxylic acid active ingredient which can deliver systemic control of target species of plants while having good tolerance of cool- and warm-season grasses. Aminopyralid can provide both pre-emergent and post-emergent control and has the capacity to control the entire plant, including the roots, and can even provide residual control to keep noxious plants from coming back.

Aminopyralid was first manufactured by Dow AgroSciences in 2005 under the brand name of Milestone. This same year, the Environmental Protection Agency (EPA) accepted the chemical and placed it under review and ultimately registered it as a “reduced risk” herbicide, making it one of the more safer herbicide chemical compounds to use due to it’s low risk to humans and the environment.

Aminopyralid based products are intended for use in rangelands, permanent grass pastures, non-cropland areas such as rights-of-way and roadsides, natural areas (wildlife management areas, natural recreation areas), grazed areas, as well as on wheat. Aminopyralid has demonstrated that it can control some of the most toughest weeds such as tropical soda apple, Canada thistle, knapweeds and other invasive species, and can deliver residual weed control at low application rates.

How Aminopyralid Works

The mode of action for aminopyralid is that it works as a plant growth regulator which possesses auxin-like qualities that can turn on and off vital plant processes like a switch. Once absorbed by the targeted plant, aminopyralid moves systemically throughout the plant and deregulates plant growth metabolic pathways, affecting the growth process of the plant, through uneven cell division and growth. Aminopyralid binds at receptor sites normally used by the plant’s natural growth hormones, resulting in the death of susceptible plant species. The herbicide is rapidly absorbed by the leaves and roots.

Within hours or days of application, depending on the weed species, aminopyralid causes symptoms such as thickened, curved and twisted stems and leaves, cupping and crinkling of leaves, stem cracking, narrow leaves with callus tissue, hardened growth on stems, enlarged roots and proliferated growth. Most annual susceptible weeds are controlled within four to eight weeks after application. Complete control of the main stems and the root systems of woody and semi-woody plants may require two or more months after application. Plant growth will stop within 24 to 48 hours after treatment. This fast killing process is what makes aminopyralid contain products so popular.

Is Aminopyralid Safe To Use?

Since aminopyralid is a relatively new herbicide, little independent information is available on the toxicity of aminopyralid to humans or other mammalian species aside from the EPA’s testing done on the chemical which showed it to be a low risk chemical. Aminopyralid has been classified as “not likely” to be carcinogenic to humans. No increases in tumors were found in carcinogenicity studies in rats and mice.

 

Aminopyralid has been shown to be practically non-toxic to birds, fish, honeybees, earthworms, and aquatic invertebrates.
