  1. In Oakland County it would be Bordines and Wojos. It might also be worth getting in touch with some of the big box stores that have significant nurseries such as home depot / lowes, walmart, menards etc.
  2. Cut it down close to the ground and apply 50% glyphosate herbicide solution to each stem. Make sure to wear rose gloves. Alternatively, spray the leaves with ~3% glyphosate or triclopyr solution.
  3. Looks like young pickerel weed to me. I would wait for it to flower and check back, or maybe get a more detailed picture.
  4. MISIN has nice PDF fact sheets for most species. As Katie mentioned, most plants are probably hybridized with Japanese knotweed at this point. http://www.misin.msu.edu/facts/factsheet.php?id=24
  5. Garlon 3A works well on swallow-wort. It should be treated in late spring or early summer to maximize effectiveness. Once seed pods develop they need to be removed and black bagged before the plant is sprayed. Garlon is a little more expensive, but won't kill your grass. Consult with your local CISMA or land conservancy for more detailed help.
  6. Hello all, The Huron-Clinton Metroparks is looking to hire a part-time Natural Resources Technician, operating out of Brighton, MI. This individual will play a large role in controlling invasive species on the ground in south-east Michigan. Please review the job posting and forward to anyone you would recommend for this job. Apply here Thanks! Tyler Mitchell
  7. MNFI has a great guide to BCPs https://mnfi.anr.msu.edu/invasive-species/JapaneseKnotweedBCP.pdf It explains that JK propagates via stem and root material, and potentially by seed. The rhizome network is immense and mechanical removal is almost impossible. Anecdotally, some of our partners have had luck carefully trimming, collecting, and bagging stems and leaves then hitting with an herbicide to tackle the rhizomes.
  8. Hello all, A partner of the Oakland County CISMA is hosting a treatment demonstration and training workshop this coming Tuesday, October 4th from 10:00-12:00 in Oakland County. I know this is last minute, but on the off chance you are able to attend, please see the details below. Thanks! ---------- Flowering rush (Butomus umbellatus) is an aquatic invasive species in Michigan, where it invades emergent wetland and lake shores. This perennial aquatic herbaceous plant grows from 1-4ft high on an erect stem in shallow water. It also grows submerged in deeper water, without producing flowers. Flowering rush can be difficult to identify when not in flower, as it resembles many native emergent plants, such as common bulrush. Flowering rush has proven difficult to treat chemically, and mechanical removal can promote spreading of the plant if not done with proper training and care. In this demonstration, participants will learn proper techniques for hand-removing Flowering Rush and containing the spread of propagules. This demonstration will include a discussion of Best Management Practices (BMPs) which you can use to develop a treatment protocol for your area. Date: Tuesday, October 4th Time: 10:00AM-12:00PM Location: Dollar Lake, 2170 Cass Lake Rd, Keego Harbor, MI 48320 This is just north of the Orchard Lake Rd intersection; in the shopping center on the west side of Cass Lake Rd. Dollar Lake is immediately behind the shopping center. Note that there is a road closure further north on Cass Lake Rd involving detours through neighborhoods, and heavy traffic is expected so approaching from Orchard Lake Rd is recommended. Gather at the north end of the parking lot. Attire and equipment to bring: Casual attire, there will be an opportunity to be get hands on experience without going in the lake. If interested in this, wear clothes that can get dirty and wet. Target audience: Lake Managers and professionals, volunteers and volunteer organizations, homeowners, government agencies, treatment contractors.
  9. The DNR was doing some field trials of different herbicides last summer; I think they have posted their results and relative success with different treatments, but have stopped short of recommending BMPs for treatment. The following PDF should hopefully contain some useful information until a time when the state can develop more concrete guidelines. I am working with a couple of OC CISMA partners to organize a group of people working on controlling flowering rush in SE MI, but it may be useful to extend our collaboration statewide. https://www.michigan.gov/documents/deq/wrd-ais-butomus-umbellatus_499876_7.pdf
  10. I'm looking forward to the event on the 23rd! Last year was great, and this year will be even better. For anyone interested, its a great way to enjoy a day on the lake and get some of those pesky MDARD commercial pesticide applicator credits out of the way.
