Noxious Weed Control

A noxious weed is a plant that the government has designated as harmful to crops, animals, habitats, or entire ecosystems.
Many of them are invasive. They choke out native plants and crops, ruin trails and recreation areas, and even poison animals. Under Rule R-68-9 Utah Noxious Weed Act, you must take action if these plants are on your property. Your neighbors will probably thank you too! Some of the most common noxious weeds in our Utah area include:
  • Thistle (Scotch, Musk, Canada, Yellowstar)
  • Dyers Woad
  • Houndstongue
  • Dalmation Toadflax
  • Hoary Cress (White Top)
  • Bindweed
  • Knapweed
Noxious weeds are tricky. They come in many forms, and can be easily confused with non-noxious plants, particularly during the early stages of development. For this reason, it’s important to hire a well-trained technician. Our technicians are certified, cautious, and thoroughly trained. Please be aware that areas with thick weed density require multiple treatments before they are under control. In addition, new weeds grow quickly and consistently throughout the season. Noxious weeds generate an incredible amount of seeds. These buggers can sit in the soil for years before sprouting. Even worse, seeds can travel a long distance, so you will likely be affected by the weeds of a neighboring property. Treating a large area for noxious weeds makes it easy to miss small patches of weeds, so some patience may be required. The battle against noxious weeds is tough, but Eco Lawn will help you take back your property. The state of Utah has a total of 27 types of noxious weeds. Each Weed has its own germination cycle and time, and so it can be tricky to stay ahead of them. We have developed a program to help control them and also keep the cost to you as low as possible. Specific dates will change from year to year depending on weather, but the general program includes 3 Treatments between April 15th – Sept 30th:
  • Spring Treatment – Late April- Mid May
  • Early Summer Treatment – June/July
  • Early Fall/Fall Treatment – Aug – Sept
Timing and proper identification is everything when controlling Noxious Weeds. Ideally you hit the weeds in their “rosette” stage before they stalk.
Once they stalk, you could have the potential for major weed problems. Each head contains thousands of seeds in it and if left alone for a year or two you will produce large infestations.

What do we use to control noxious weeds?

Our main weed control is Milestone, a specialty herbicide. It was designed to kill nasty weeds in native areas, trails, pastures, and open spaces. It is not an organic product but is considered one of the lower impact products on the market that has proven to be effective.

Milestone is labeled to kill over 50 types of weeds including thistles, Henbane, Knapweed, Henbit, Oxeye Daisy, Chicory, Horseweed, Curly Doc, Yarrow, and even Ragweed.

It is registered as an EPA “reduced risk pesticide.” It has such a low toxicity that it is considered non-toxic to human, fish, bees, and birds. Once applied it is broken down by soil microbial activity very quickly and does not leach through soil. It will not injure desired grasses.

In areas that do not have desired grasses or vegetation we can use a non-selective herbicide called Finalsans. This is an organic non-selective weed control made by Neudorff. Its active ingredient is soap of fatty acids.

Milestone is registered by Dow AgroSciences LLC under the EPA Reg. NO. 62719-519
