What is a WEED?
A variety of opinions abound on this subject. Most consider a
to be any plant that is on either the Colorado Noxious Weed list
or any plant on your land that you consider undesirable.
What is a NOXIOUS WEED?
Noxious weeds are plants that are
to North America. They have no natural predators and can easily
The following comes from an Executive Order put forth by
Governor Bill Owens:
"All land owners have a responsibility to plan and implement
a coordinated program that utilizes a variety of integrated
methods to manage noxious weeds, the purpose of which is to
achieve desirable plant communities."
for all landowners to realize the vigorous competition Noxious
Weeds present to our native habitat. Once some of these more
tenacious perennials have established themselves, it can take
years of vigilant efforts to bring them into check.
Why should I control my NOXIOUS WEEDS?
There are several reasons we need to control noxious weeds:
Colorado has a
which mandates eradication, control and suppression of a variety
of Noxious Weeds that thrive in Colorado
Noxious Weeds lessen the productivity and graze ability of your
Left unchecked, Noxious Weeds can rapidly choke out other plants becoming a monoculture and keeping native plants and grasses
from populating your land
ďIt is currently estimated that more than 43 million acres (65%)
of Coloradoís 66 million acres of public and private lands are
deemed by local weed management professionals to be, on average,
in less than adequate compliance or cooperation with
local weed management efforts.Ē

Noxious Weed infestations impact agriculture; land values;
wildlife grazing habitat; native threatened and endangered
species; recreation and tourism.

How much will Weed Control Cost?
It is difficult to say as each infestation and property site
varies. The type of application required will be based on
a variety of issues:
If Water is Present, etc.
The greatest factor
in determining costs is the target weed and subsequent chemical
necessary to control it. The chemistry developed to selectively
control specific weeds varies as does the effect those chemicals
will have on the target plants. Some of the more common
modes of action inhibit photosynthesis and growth.
Therefore as you can see, an accurate assessment of a variety of
issues will determine the costs of control.
What time of year is best to control Pest?
There are such
a wide variety of pests all of which need to be treated at
various times throughout the year. Please visit our
to determine what the best times of year are for a number of
different pests. Keep in mind that the dates listed may vary
based on weather and physical location of the infestation.
How are Noxious Weeds controlled?
Integrated Pest Management (IPM) is common strategy in
developing methods of control. IPM may consist of one or
multiple accepted methods of Biological, Chemical, Mechanical
and Cultural controls. We can assist you by making
recommendations on all methods. We conduct inspections, write
management plans, and conduct Chemical and occasionally
Biological control methods.
Be advised that
is the most commonly used and most effective method of weed
control. We understand that it is also controversial;
subsequently we are sensitive to community/environmental impact.
We take our chemical treatments very seriously
maintaining our licenses through attending numerous continuing
education programs and by keeping up to date on the latest products and
Rules/Regulations as administered by the Colorado Department of
We select only those herbicides and insecticides that will
effectively target the pests you have hired us to control
ensuring no damage to grasses and desirable vegetation.

There are a wide variety of ways this might happen:
There might be a seed bank in the soil Ė some Noxious Weed seeds
can remain viable in the soil for 2-15 years and disturbing the
soil may well cause these seeds to germinate
Climate conditions may trigger seeds which have been dormant
Not utilizing Weed-Free Certified Feed (Hay) by you or your
Wind, Birds and Animals may carry or drop seed on your land
Weed seeds may be transported by vehicle/trailer tires,
clothing, shoes and even pet fur

Donít pick wildflowers or noxious weeds and try not to walk or

Weed Management professionals agree and advise that in order to
control noxious weeds it will require multiple treatments.
It is important to develop multiple year plans especially on
infestations that have been present for years. While a one
time treatment may be effective in reducing a population, annual
inspection and maintenance is key. Not doing so may result
in wasted dollars from your initial treatment investment.

herbicide is applied to the targeted pests. We always follow
recommended rates of application and will not reduce rates in an
effort to save you a few dollars as doing so will cost you far
more in controlling your noxious weeds in the long run. It is
important to recognize that developing a watchful management
plan is imperative to effectiveness.
Are the chemicals you use harmful?
The chemicals we use have been tested for years and would
not be allowed on the market were they not safe. We read each
label at least 5 times before and after using the chemical to ensure
we are following all of the guidelines put forth by those
It is our policy that any chemical classified as a known or
probable human carcinogen by the Environmental Protection
Agency, National Toxicology Program or the International Agency
for Cancer Research, will not be used.

What is a pesticide?
A pesticide is any substance or mixture of
substances intended for preventing, destroying, repelling, or
mitigating any pest.
Though often misunderstood to refer only to insecticides, the
term pesticide also applies to herbicides, fungicides, and
various other substances used to control pests.
If chemicals are safe, why then do you
place a Warning sign on my property after performing a chemical
These markers are not warning signs. In compliance with
the Pesticide Applicators' Act, we are required to notify and
post any time we make a pesticide application in any turf or
ornamental category. We will post on all of our jobs so
that our clients and their neighbors may take whatever
precautions they feel are necessary, should they be concerned
about contact with pesticides. We advise our customers to
keep family and pets off treated areas until the application has
dried or as the label suggests.
toxic are the products you use?
The products we use
generally contain the same active ingredients that are found in
most of the garden products you can purchase at retail garden
and hardware stores. The difference is most products sold
at these outlets are meant to be applied directly and products
we use are in much larger quantities to be diluted to various
strengths depending on the target pest.
The large majority
of the products we use contain a "Caution" label. Caution
refers to products of relatively low toxicity and those that are
comparatively free from health hazards. Acute Toxicity is
measured in LD-50 (This figure is the dose that is lethal to 50% of
The higher the LD-50
number, the safer the product.
