Scientist Finds Promising Management Tool for Cheatgrass
By Lesley Beckworth - Invasive Species Program Coordinator
        Controlling infestations of cheatgrass (Bromus tectorum) can be both expensive and labor intensive. Currently, there are very few herbicides on the market for cheatgrass control, none of which provide selective control options. However, Ann Kennedy, a research scientist at Washington State, has isolated a bacterial strain that shows promise in aiding in cheatgrass management.
       The bacterium (Pseudomonas fluorescens) is naturally occurring in the soil and is already in use in agricultural settings.  Dr. Kennedy found that when P. fluorescens is present in the soil, cheatgrass loses its competitive edge allowing native species to revegetate the area. P. fluorescens has not been found to affect any native species. Instead, the bacteria secrete a chemical that binds
into the roots of cheatgrass and limits the plant's ability to uptake nutrients while allowing native species to thrive. As the bacteria build up in the soil over the following years, increasing impact on the cheatgrass infestation occurs. With the addition of low rates of herbicides, cheatgrass infestations face more rapid declines.
        A company in Idaho has started the process rearing the bacteria for use as a bioherbicide which is currently being evaluated by the EPA. Pending this approval, applications of the bioherbicide could begin as early as October 2016. TCWP is very excited at the prospect of adding this bioherbicide to our arsenal for cheatgrass control.   Source

Play Clean Go in the SNOW!
By Amy Collett, Marketing and Education Coordinator 
         Temperatures are dropping and snow will soon blanket our landscape covering up most of the vegetation for the winter.  However, some of them remain tall and full of seeds waiting for an animal or skier to brush by to take them somewhere new. Just when you thought you got a break from invasive species, think again. Even during the winter it is a good practice to Play Clean and Go! 

Many of the invasive species that we work so hard to kill are also very strong and withstand the weight of the snow. Musk thistle, spotted knapweed, and our biggest hitchhiker; houndstongue are a few of those to keep an eye out for while enjoying your favorite winter sports.  Please remember to Play Clean and Go all year around to do your part reducing the spread of invasive species.

TCWP would like to give a huge Thank You to 1% for the Tetons for funding an Early Detection, Rapid Response grant in the Teton range! 

Winterizing Herbicides and Equipment
By Travis Ziehl, Assistant Supervisor
1. Read the labels of herbicides applied to determine how to dispose of any left over product, or if there are any special instructions that might be necessary.
-Most herbicides recommend storage above 32 degrees Fahrenheit.
-Store chemicals in a spill proof container (plastic, metal, NO Wood), to allow for clean up if a spill occurs.

2. Disposal of herbicide containers
-Herbicide containers can be recycled, but must be triple rinsed.
-If you have leftover herbicide that must be disposed of, contact the
Jackson Community Recycling Center or call 733-7678

3. Rinse sprayer to remove any left over product that may be in or on the sprayer.
-Be sure to select a rinse site that is in accordance to the label as to not contaminate water supplies, streams, or cause damage to desired vegetation.

4. Clean tanks inside and out to remove any further residue.  
-Rinse again using precautions above

5. Inspect all hoses, valves, fittings, nozzles, screens, pumps and engines for needed repairs.

6. Store Add antifreeze (RV grade) to tank and allow to circulate through system in order to coat all components. This prevents any water from freezing in critical areas (valves, pumps, etc).
-Of course, inside storage away from the abuse of the elements is preferred.
Remember to Feed Weed Free!

        This is a friendly reminder that Teton County, Wyoming has a quarantine against the entry of any infested farm products like straw, hay, and feed. This is in place to reduce the spread and costs of invasive species. Help stop the spread!       
          As September rolls around and hunting season starts many folks are in need of certified hay. The District maintains a list of producers that raise certified weed free forage and it is available by contacting our office at
