As you probably know, the nasty invasive weed houndstongue (Cynoglossum officinale (Boraginaceae)) has small oval/flat seeds that stick to about everything. I have spent countless hours combing them out of my Brittanys fur after bird hunts (spray-on cooking oil helps but then you must bathe your dog after that...). My Father and I shot two elk one season several years ago who's head/necks were covered with houndstongue seeds. We hunt that area often and knew of no houndstongue plants within...
The Whitehall Biological Weed Control Project is up and running this season, modified a bit of course for COVID safety. Our first order of business is looking for 8-10 Canada thistle fungus release sites. This will entail two visits to each site. One now (May/early June) to set up a long-term sampling transect. The second visit will be in September/October to infect the plants with the fungus. Many Montana sites are showing fairly severe damage to the Canada thistle patches the season after the...
The Whitehall Biological Weed Control Project has had a busy year. We started June 1st and have collected/released the following numbers so far: Mecinus janthiniformis (Dalmatian toadflax stem weevil, collected near Missoula and Helena): 4,100 = 41 releases.

There are 6 species of flea beetles approved for release on leafy spurge. They are: Aphthona abdominalis Aphthona cyparissiae Aphthona czwalinae Aphthona flava Aphthona lacertosa Aphthona nigrascutis They are a very small beetle with a back "hopping" leg somewhat like a grasshopper. Some of these species are black, and some are coppery brown. The adults emerge from the soil from mid-June to mid-July in Montana. Adult feeding creates many holes and chewed edges on spurge leaves. They make an...
After a decade of being a not-for-profit organization, we are back under the auspices of the Jefferson County Weed Board and Jefferson County. We are pleased to be working under the direction of Jefferson County Weed Coordinator Jill Allen. We received a Noxious Weed Trust Fund grant as usual and are receiving monies/voluntary donations from the Montana Department of Transportation, State DNRC, other counties and agencies and of course, the numerous wonderful landowners to whom we provide...
