WHAT ARE
NOXIOUS WEEDS?
Noxious weeds are plants usually of foreign
origin that are directly or indirectly injurious to public health, crops, livestock,
wildlife, land or other property.
WHY
CONTROL NOXIOUS WEEDS?
These weeds have serious impacts on residents of
Duchesne County. Noxious weeds are becoming the number one threat to our public and
private lands. If you own or manage property in Duchesne County you should be concerned
about noxious weeds.
WHAT
ARE THE IMPACTS OF NOXIOUS WEEDS?
Economic Impacts:
Duchesne County for the past several years has spent approximately $120,000.00 per year
controlling noxious weeds on county lands and roads. Whether you are a farmer, a hunter, a
mountain biker, a property owner, a consumer or a bureaucrat, problems caused by noxious
weeds have direct economic impacts.
Impacts to Crops:
As these weeds invade crop areas they steal precious soil nutrients from crops.
Thus, reducing crop yield and quality and in turn costing you money.
Impacts to livestock and wildlife:
Noxious weeds on rangelands displace native grasses and reduce forage for
livestock and wildlife. Many noxious weeds are poisonous and can harm livestock. Russian
Knapweed is toxic to cattle. Many key winter ranges for wildlife are invaded by noxious
weeds reducing available feed for wintering game.
Impacts to Recreation:
Noxious weeds affect recreation areas. Muck thistle can become so thick along
stream banks that people cannot fish these areas. The aesthetic value of our country
scenery is effected by the invasion and spread of noxious weeds.
ARE THERE LAWS ON CONTROLLING NOXIOUS WEEDS?
Under the Utah Noxious Weed Act, all land owners
are required to control noxious weed infestations on their property and are required to
prevent noxious weeds from spreading off their property.
HOW DO
NOXIOUS WEEDS SPREAD?
These weeds are spread by wind, water, animals,
and humans. Noxious weeds are spread in contaminated hay, straw, seed, grains, equipment,
top soil, manure, tire treads, and on our clothes.
BE AWARE!
Learn to identify noxious weeds. Be familiar
with your land and surrounding lands. Report infestations of noxious weeds to landowners.
If you see noxious weeds on public lands notify he agency managing these lands.
TAKE ACTION!
As a land owner you are responsible to prevent
noxious weeds from moving off your land as well as controlling existing infestations.
BE RESPONSIBLE!
Plant weed-free seed of desirable plants.
Keep weeds out of un-infested areas.
Clean machinery, cars, trucks, and recreation
vehicles that have been in infested areas before moving them to areas not infested.
Keep weed infested hay, straw, and manure out
of un-infested areas.
Don’t purchase infested hay, straw, seed or feed.
Encourage and help your neighbors become
informed about noxious weeds and their control.
LEARN HOW TO
CONTROL!
Don’t allow weeds to reproduce.
Map out infested areas on your land.
Use an integrated approach to control the
weeds using chemical, cultural, mechanical, and biological control methods.
Evaluate your use of chemicals.
Rotate herbicides to prevent weed resistance.
Carefully read and follow label directions for
all herbicides used.
Follow up on all control efforts.
