Discarding Empty Pesticide Containers & The Montana Pesticide Disposal Program

Thursday, August 21st, 2014


Pesticide applicators should be aware of the resources available for discarding pesticide containers and pesticide waste. By following a few simple steps applicators can ensure that empty and partially filled pesticide containers are discarded and disposed of legally.

Disposing of Empty Pesticide Containers

Prior to discarding any pesticide containers a pesticide applicator is required to power-wash or triple rinse the containers. The rinsate should be discarded in pesticide tanks and sprayed over a site listed on the pesticide product label at or below required product label rates. After triple rinsing, the container should be rendered unusable by puncturing. The Montana Department of Agriculture Pesticide Container Recycling Program is an option for applicators desiring to keep pesticide container plastic out of Montana’s landfills. This program has collected more than 288,000 pounds of pesticide containers since October 2009. Numerous sites across Montana are available that applicators may use by simply searching the container recycling map at Once an acceptable site is found, applicators may contact the local cooperator to arrange a drop off of empty pesticide containers (refer to the recycling map link). Shredded plastic from pesticide containers is recycled to create non-consumer items such as drain tile, roadway speed bumps, pallets and landscape edging.

Disposing of Pesticide Waste

Applicators should use the Montana pesticide waste disposal program if they have unknown pesticide products (due to worn product label), unregistered pesticide products or unusable pesticides that are in need of disposal. The Montana pesticide waste disposal program began in 1994 and has collected more than 455,600 pounds of pesticide waste since onset. Common pesticides brought to the event include DDT, chlordane, 2,4,5-T and strychnine. The disposal fee is FREE for the first 200 pounds and $0.50/lb for amounts in excess of 200 pounds for licensed pesticide applicators. Pesticide disposal program locations and dates are:

  • September 16, 2014 – Kalispell, MT
  • September 17, 2014 – Polson, MT
  • September 18, 2014 – Missoula, MT
  • September 19, 2014 – Bozeman, MT

Participants must pre-register their unusable pesticide with the Montana Department of Agriculture before the event. Registration for the program is requested by the end of August. For the most part, acceptance into the program is on a first come, first serve basis and early sign-up is encouraged. Requirements: Participants must pre-register their unusable pesticide with the Montana Department of Agriculture so the collection can be managed safely and efficiently.

Montana Department of Ag Releases the Revised Noxious Weed List

Are there grants available to help treat noxious weeds?

Thursday, April 18th, 2013


There are several sources available to treat noxious weeds, but rarely to one landowner. If a weed management area is formed with several landowners, the chance of receiving grant funds increases. The MT Department of Ag’s Noxious Weed Trust Fund is one avenue to pursue grants, the deadline is usually the first of December and forms can be found online. On a larger scale, the National Fish and Wildlife Foundation offers grants, and Department of Natural Resource Conservation and local conservation districts also offer grant funds. You can check with your local conservation district office to inquire about possible funding. Currently NRCS is also providing grant funding through special initiative funds called EQUIP. Several other Montana organizations offer grants including PPL and Rocky Mountain Elk Foundation.   Again, when a cooperative weed management area (CWMA) is formed and organized well, there are several avenues of funding available. Please check out our grant opportunity postings on the MWCA Classified  Web Page where we put all opportunities that we become aware of.

Montana Noxious Weed Trust Fund Grant Funding Opportunities for Fiscal Year 2013

Monday, September 10th, 2012


The funding opportunities for fiscal year 2013 are posted on the WebGrants website at Applicants must contact and work with an organization, such as a weed  district, conservation district, extension office, or tribe to determine if they will be the funding recipient for the grant dollars and submit the application.

Please let anyone know about this grant program who is interested in noxious weeds and developing a local cooperative, education, or research project. Remember that all grant applications must be submitted by midnight on December 3,2012.

The changes for the 2013 Trust Fund grant cycle are:

  • Grant applications are only accepted by using WebGrants.
  • Attachments (photos, supporting documents, environmental assessment information) must be web friendly for uploading and download. Remember to re-size pictures and to try to make all attachments less than 1 MB in size.
  • Do not wait until the day before the deadline to start working in WebGrants. Please plan accordingly to allow enough time for any problems you may have getting familiar with our web based grant management system.
  • ALL local cooperative projects need to attach a picture of the noxious weed situation that helps depicts the reason why funding is needed for the new project or why the current Trust Fund project needs continued funding.
  • Start early on the environmental assessment process so you have all the necessary documentation to attach to the application by December 3rd.

If you have any questions using WebGrants or would like help in developing a weed project, please feel free to call Dave Burch, State Weed Coordinator at 444-3140 or Kim Johnson,  Grants Coordi nator at 444-1517. You can also contact Carol Bearden at 444-7880 for help with WebGrants and completing the application process.

MT Department of Agriculture’s Aquatic Invasive Species Summary for 2011

Friday, May 4th, 2012


Report Objective:

This report provides an annual status report on aquatic invasive species (AIS) work performed by the Montana Department of Agriculture. Aquatic invasive species include any plant or animal that is not native to Montana and poses a threat to the biologic or economic health of the state. Management authority for aquatic noxious weeds in Montana is the responsibility of county weed districts with support from the Department. Aquatic invasive weeds currently include Eurasian watermilfoil (EWM) (Myriophyllum spicatum), curlyleaf pondweed (Potamogeton crispus), and flowering rush (Butomus umbellatus), all listed under the Montana Noxious Weed List. The Department also cooperates with the Department of Fish, Wildlife, and Parks (FWP) and the Department of Natural Resources and Conservation (DNRC) to prevent introduction and spread of all aquatic invasive species including zebra and quagga mussels.
