Global Invasive Species Team listserve digest #101 Mon Mar 18 2002 - 17:07:32 PST --CONTENTS-- 1. Nina Totenberg, Cokie Roberts, and John Randall (Global) 2. Sidewinder tree injectors (Global) 3. Weed Survey (Great Lakes Area, USA) 4. Herbicides with surfactants and other adjuvants (Nationwide, USA) 5. Southeast Exotic Pest Plant Council Symposium (Southeastern USA) 6. Wet-blade mowers (Montana, USA) 7. Native range of Xanthium (Virginia, USA) 8. Hedera helix, soap, and borax (California, USA) --------------------------------------- 1. Nina Totenberg, Cokie Roberts, and John Randall (Global) From: John Randall (jarandall(at)ucdavis.edu) National Public Radio's reporter Ketzel Levine who specializes in gardening stories is working on a 4-5 minute piece on ornamental plants that have proven to be invasive, and it is scheduled for airing on the Morning Edition news show on the 20th. She interviewed folks from the "no-ivy league" in Portland, Oregon who manually remove invasive English ivy and other weeds from parks and natural areas around Portland for part of the story. She also interviewed me as we walked around a nursery and spotted species for sale which are invasive in one part of the nation or another. Listen in Wednesday morning, March 20th, to your local NPR station and hear for yourself! --------------------------------------- 2. Sidewinder tree injectors (Global) From: Barry Rice (bamrice(at)ucdavis.edu) Has anyone used injection equipment developed by Sidewinder? Their web site (http://www.users.bigpond.com/sideject/) has photographs of pretty interesting gear---basically, they combine a cordless electric drill with an herbicide dispenser. The firm is in Australia, and doesn't give prices on their web pages. --------------------------------------- 3. Weed Survey (Great Lakes Area, USA) From: Mariquita Sheehan (msheehan01(at)fs.fed.us) The Great Lakes Indian Fish and Wildlife Commission and the Invasive Plant Association of Wisconsin seek your help in developing and prioritizing a list of non-native invasive plants that threaten native plant communities in Wisconsin. Our objective is to develop a prioritized list that ranks each species from a consistent set of ecological criteria and methods. Although our focus is Wisconsin, we expect the results of this effort will have wider regional applications depending on the response rate from neighboring states. To learn more about this project, and to download the survey so you can share your knowledge about your favorite weeds, go to http://tncweeds.ucdavis.edu/news/031502.html --------------------------------------- 4. Herbicides with surfactants and other adjuvants (Nationwide, USA) From: Mandy Tu (imtu(at)tnc.org) As some of you may know, we here at WIST are working hard on an additional chapter on the use of adjuvants with herbicides, for our Weed Control Handbook. Unfortunately, there are no available guidelines that suggest which brand of adjuvant should be used with each herbicide (only types of adjuvants, such as nonionic surfactants, crop oil concentrates, etc. are recommended on the herbicide label). So I am looking for any examples of successful weed control using the herbicides: 2,4-D, clopyralid (Transline), fluazifop (Fusilade), fosamine ammonium (Krenite), glyphosate (RoundUp and Rodeo), hexazinone (Velpar, Pronone), imazapic (Plateau), imazapyr (Arsenal), picloram (Tordon), sethoxydim (Poast), and triclopyr (Garlon 4). If you have been successful (or unsuccessful!) at controlling weeds using one of the above herbicides, please send me information including specifics such as: species used against, method of application, which brand and how much herbicide and adjuvant used (% concentration), and approximate amount of the weed killed (% kill). I would also like to list YOU as a potential contact person on this table, if you do not mind. Thanks!! My email is imtu(at)tnc.org, phone is 503-230-0707 x350. --------------------------------------- 5. Southeast Exotic Pest Plant Council Symposium (Southeastern USA) From: Barry Rice (bamrice(at)ucdavis.edu) Brian Bowen sent me some updated information on the Southeast Exotic Pest Plant Council Symposium that will take place 3-5 April, in Nashville Tennessee. You should go. I have posted information about this event at: http://tncweeds.ucdavis.edu/meetings.html --------------------------------------- 6. Wet-blade mowers (Montana, USA) From: Celestine Duncan (weeds1(at)ixi.net) I'm working on a weed plan for Missoula County roadside veg program. I am interested in finding information on wet-blade mowers and whether any are practical for roadside invasive plant management. If you have any info on, or experience with this equipment please let me know. --------------------------------------- 7. Native range of Xanthium (Virginia, USA) From: Jil Swearingen (elytra(at)earthlink.net) It is important to distinguish between native and introduced cockleburs lest folks get the impression that they are all bad in all instances. While Xanthium spinosum (spiny cocklebur) was introduced into the U.S., Xanthium strumarium (common or rough cocklebur) is native at least to some parts of U.S. (I don't have the specific range information on hand). It is listed as a noxious weed because of its weediness to agriculture and as invasive in natural areas by some others (NPS, Tennessee Exotic Pest Plant Council, and Virginia Native Plant Society) in the southwest (Chiricahua and Dinosaur Natl Monuments) and a few natural areas in the East. We need to find out the native range of common cocklebur in the U.S. and remember to treat it different from the introduced spiny cocklebur. --------------------------------------- 8. Hedera helix, soap, and borax (California, USA) From: Andrea Pickart (layia(at)tidepool.com) Is anyone familiar with the technique of using a diluted solution of Borax and liquid soap to kill English Ivy (Hedera helix)? |
