Bonneville County Weed Department
The goal of this program is to implement County and State weed ordinances. We will accomplish this by achieving the most effective Vegetation Management Program for the preservation of Bonneville County’s valuable property by utilizing Education, Mechanical control, Biological control, Cultural control, and Chemical control for the betterment of Bonneville County and its neighbors. The effectiveness of this program is due to the authority and cooperation of the County Commissioners.

Rules and Regulations
For many years there has been a push for laws supporting weed control. One of the first enactment of this kind of legislation was in 1975 as the Federal Noxious Weed Act (FIFRA) through many changes in the legislature we now have the Plant Protection Act of 2000 (which suspended FIFRA). Each of these acts enabled the government to take a stand against noxious weeds to protect public health, livestock, and the lands of the United States.
Weeds are determined as NOXIOUS by the Secretary of Agriculture, United States Department of Agriculture (USDA), and/or a designated person from each state. This individual will declare a weed NOXIOUS by its potential harm to people, crop production, livestock, and property.
In Idaho we have a State Noxious Weed Law which governs (via legislation) the enforcement and control efforts as well as outlining obligations of each county in Idaho.
Idaho's Noxious weeds are plant species that have been designated "noxious" by law in the Idaho Code (title 22, chapter 24, "Noxious Weeds"). The law is implemented using administrative rules. THese rules are contained in IDAPA (Idaho Administrative Procedures Act) 02, title 06, chapter 22 "Noxious Weed Rules."
For information on the State Noxious Weed Law click Idaho State Noxious Weed Law
Bonneville County Nuisance Weed Ordinance
Within Bonneville County we utilize the State Weed Law as well as a Nuisance Weed Ordinance. The Nuisance Weed Ordinance specifies that weeds are not to exceed 10 inches in height. Bonneville county may send enforcement letters to the owners of property who are in violation of this ordinance instructing them to mow, till, or disk their property.
Each county is allowed to make there own weed ordinances which may include weeds deemed as a threat for their county or a nuisance weed ordinance for their county. This is accomplished through action of the County Commission.
For information on contract mowing, contact our office and we will supply you with contact information for custom mowers, that we are aware of, from this area.
Cost Share Programs:
In many situations dealing with only Noxious Weeds BCW is able to offer financial help with controlling these invasive weeds. Currently there are only 67 listed weeds. Our current program is to offer a 50:50 cost share to land managers who qualify for the program. To qualify contact our office (208-529-1397) and we will work out the details. Many other Idaho's State CWMA's have offered free herbicide to land managers.
It is our belief that all land managers should invest in their own weed control. Offering free product does not guarantee that you are going to get it on the weeds. By investing in 50% of the costs we believe that the land manager will ensure the quality of weed control.
One exception to this is if we, the CWMA, have a "SPRAY DAY" where all partners come together on one site and work will all land managers in the geographic area. Here land managers may show up with their sprayers and the CWMA will train, calibrate, and mix a load for you and you go treat your own weeds. These are some of the most effective weed management techniques across a single landscape.
Contact our office and we can visit about having a 'SPRAY DAY' in your area.
A Weed Warrior maintains and preserves the land through many different types of weed management. Always striving to use the right tool for the right job. In order to find the right tool for the right job a weed warrior must first identify what weed they are trying to control.
There are some 467 noxious weeds in the state of Idaho. Each weed is listed under 1 of 4 different categories - Prohibited, EDRR, Control, and Containment.
The term NOXIOUS is a term applied to those plants that are illegal to sale, possess, or transport in the state of Idaho. The plant is designated by the Director of the Department of Agriculture then approved by our State Legislators. Other plants that are also regulated, mostly by permit process from ISDA, include Bio Fuels and Trap Crops.
Some 400 hundred prohibited plants are any member of the Broom family.
Chamaecytisus nor Cytisus nor Genista nor Spartium Genera
This was done in conjunction with the Idaho Association of County Weed Superintendents to stop some of the Major Nursery Retailers (Home Depot, Lowes, WalMart, Fred Meyers, etc) from selling any of these look-a-likes to Scotch broom. There are no Brooms that are native to North America and they all have the same characteristics to become invasive and noxious. The is key to a prevention program in the state of Idahol.
(Early Detection Rapid Response) *Plants in this category must be reported to the Idaho State Department of Agriculture (ISDA) with 10 days after being identified at the University of Idaho or by another qualified authority approved by the ISDA Director. Eradication of these weeds must begin in the same season they are found.*
Noxious and potentially Noxious weeds that may not be in Bonneville County and require the most attention.
EDRR Weed found in Bonneville County is Policeman’s helmet, believed to have been eradicated
Plants in this list may already exist in some parts of the state. In some areas of the state control or eradiction is possible, and a plun must be written that will reduce infestations with-in 5 years.
Noxious weeds that have a minimal presence in Bonneville County and it is believed that these weeds can be removed within a few years and monitored thereafter.
Control Weeds in Bonneville County are Black henbane, bohemian knotweed , Buffalobur, Dyer’s woad, Flowering Rush, Japanese knotweed, Perennial sowthistle, Russian knapweed, and Small bugloss.
|Dyers woad||Small Bugloss||Purple loosestrife|
|Puncturevine||Leafy spurge||Whitetop/Hoary cress|
|Musk thistle||Houndstongue||Spotted knapweed|
Weeds that pose the greatest economical threat to property. These weeds have a strong presence in the county and the intention may not be to eradicate all patches, but to contain the weeds in their current location and help landowners manage them.
Containment weeds in Bonneville County are Canada thistle, Curlyleaf pondweed, Dalmation toadflax, Diffuse knapweed, Field bindweed, Houndstongue, Jointed goatgrass, Leafy spurge, Oxeye daisy, Perennial pepperweed, Plumeless thistle, Poison hemlock, Puncturevine, Purple loosestrife, Rush skeletonweed, Saltcedar, Scotch thistle, Spotted knapweed, White bryony, Whitetop, and Yellow toadflax.
Nuisance weeds are weeds that Bonneville County will control if they are becoming a problem for the lands of the County.
Some Nuisance weeds are Chicory, Common Tansy, Marestail/Horseweed, Scentless chamomile, and St. Johnswort.
Education and Outreach
Link for a Weed of the Week webpage written by Jeffrey Pettingill.
We are always looking for opportunities to educate groups from Elementary students to community groups.
For great information on weeds and identification go to Idahoweedawareness.com
Have a weed/plant you would like to have identified as well as obtain methods of control here is what to do:
*Dig up plant - place entire plant into a damp substrate such as an old newspaper - place this into a plastic bag (place into the refrigerator if over a day delivery time) - bring it to our office 2702 Manwill Road, Idaho Falls, Idaho
Identifying the possible invader, determining cause of invasion, and then finally developing a managment or prevention program is key to preserving the natual landscape. When you have a weed problem we can investigate the area as well as give advice on how to fix the problem as well as prevent it from happening again. In most cases we can also assist with the proper tools to deal with the problem. SEE equipment rental program below.
Noxious Weed Free Forage and Hay: Noxious weed free forage is required when taking livestock onto U.S. Forest Service or Bureau of Land Management Lands to protect them from new invasions.
Bonneville County Weed Department has two employees that are Idaho State Department of Agriculture certified to certify forage and hay for the presence of Noxious Weeds. We can certify locally (state noxious weeds) or regionally (over 100 weeds so that the product can be shipped accross state lines). For more information see ISDA Noxious Weed Free Forage and Hay Program or to find Certified hay in your area.
Typical costs for herbicide application plus materials.
0-4 acres—$15.00 per acre or $60.00 minimum

Weed Warrior Workshop
We host a training workshop for all applicators in Eastern Idaho. This will be a two or three day workshop for current pesticide license holders as well as training for new applicators. Presenters will be Chemical and Equipment representatives along with professional weed managers. Normally held the first or second week of June.
Upper Snake River Highlands Rangeland Conservation Project
We identify problems areas, contact landowners, and assist with the weed control efforts. The programs boundaries are from Wyoming/Idaho border to the top of Granite Hill, From Teton/Bonneville County line to the top of Fall Creek. While all noxious weeds are our target there are a few weeds that this program is specifically interested in controlling. These weeds are Canada thistle, Dalmatian toadflax, Diffuse knapweed, Houndstongue, Leafy spurge, Musk thistle, and Spotted knapweed.
Grays Lake Rangeland Conservation Project
This project is funded by the Highlands CWMA and includes all the landowners in the Grays Lake area. While we are on the look out for all noxious weeds there are specific weeds that we are also watching out for in this area. These weeds are Canada thistle, Houndstongue, Musk thistle, Spotted knapweed, Whitetop/Hoary cress, and Yellow toadflax.
Rural Idaho Falls Weed Reduction Project
Bonneville County intends to work will all land owners around the Idaho Falls area in the reduction of impact of invasive plants. With this we will generally offer a 50:50 cost share program for approved private land owners and land managers in the control of Noxious Weeds only.
This project is a collaboration of weed control efforts along the Union Pacific Railroad and Eastern Idaho Railroads in Eastern Idaho. All counties along the system collaborate and control weeds along the right-of-way over a few days, mostly with ATV's.
We work very close with the Univesity of Idaho Bio Control Research Lab as well as the Nez Perce Tribe Bio-Control Center. Tap on the ICONs at the end of page to obtain more informaiton.
This project involves using insects as well as animals to help manage noxious weeds. This will only work on plants that have listed Biological controls agents. While this is not a “silver bullet” it is an additional tool in the weed management toolbox. Preferably used along side a herbicide treatment.
In most cases Bonneville County will inspect the site, procure the appropriate Bio-Control insect, and upon arrival we will disperse the bugs. There is generally no charge for this effort.
Interestingly it takes more time to get a new prescription drug registered for use than it does an insect for weed management....
Weed Mapping and Inventory
Mapping involve the use of Global Positioning System or GPS units to map the location of noxious weeds in the county. By mapping these noxious invaders we will be able to see the distribution of noxious weeds in our area helping us know areas that are in need of our attention. In order to be effective at managing the weeds in our county we need to know what is out there and mapping helps us accomplish this goal.
An important tool in the weed management toolbox is our connections. Click on any of the links below to see the websites of other helping hands in the fight against noxious weeds. Also where would we be without our educators; so take a look at the schools and programs that are affiliated with the fight against noxious weeds.
