    Fast growing tree?

    Claire Peterson replied to Claire Peterson's topic in What is it? Species Identification Help

    That is what I was leaning towards but I wasn't 100% sure... I know we have a few white mulberry trees (boo ) in our field but I was really surprised to see it growing here.

    Fast growing tree?

    Katie Grzesiak replied to Claire Peterson's topic in What is it? Species Identification Help

    Mulberry, likely non-native (sometimes invasive) white mulberry, Morus alba.

    Hi all, wondering if you could help me out. This, I am assuming tree, popped up next to our air conditioner a few weeks ago and it has been growing like crazy. I swear its grown 2 feet in a week...Anyone have any idea what it could be?

    Thanks Christina!

    Round goby?

    Christina Baugher replied to Claire Peterson's topic in What is it? Species Identification Help

    Yes, it's a round goby. (A key characteristic is the black spot on the dorsal fin).

    The invasive plant is widespread in New York and was recently spotted for the first time in Virginia, but conservationists believe they can fight it. View the full article

    Looking for any success stories for yellow flag iris. I've read imazapyr and glyphosate will work, just looking for some confirmation/first hand experience. Thanks!

    Thanks to an interested partner and the advice of experts from across the state (special thanks to DNR FRD, MDARD, and the Forestry Assistance Program), ISN created this quick reference guide regarding how firewood can be heat-treated to no longer bear the threat of moving invasive species. See attached! The "Downloads" page wasn't working at the moment, but I'll put the PDF there as well soon. Firewood heat treat.pdf

    I haven't heard about them in the US, and would be pretty skeptical--with knotweeds sprouting through concrete and asphalt, and anecdotal evidence of even puncturing trailer tires (the landowner who told me that didn't get photos, I'm very upset), I would be REALLY impressed if they found a barrier that really worked.

    Round goby?

    Katie Grzesiak replied to Claire Peterson's topic in What is it? Species Identification Help

    @Sarah LeSage or Jane Perrino or another aquatics person is probably best able to answer this, but it sure looks like the round gobies I've seen.

    Round goby?

    Claire Peterson posted a topic in What is it? Species Identification Help

    Reported to us last week and the person who caught this fish was not 100% sure if it was a Round goby or not. Any help would be appreciated!

    Has anyone heard of knotweed root barrier membranes being used in the United States? Either by contractors or municipalities for large projects. There is a new road going in through an acre lot contaminated with F. japonica in Kalamazoo County and they are interested in mitigating it the best way possible. Thanks!

    Website Updates

    Claire Peterson posted a topic in General CISMA Discussion

    Hi CISMA coordinators! I just wanted to take a moment to remind you to review your CISMA page on the MISC website and make sure all the information is up to date! Also, please feel free to upload photographs from last years field season to our Gallery on the forum!

    Knotweed treatments

    Katie Grzesiak replied to Katie Grzesiak's topic in Best Management Practices (BMP) and Treatment

    Unfortunately, not really any updates. We've moved away from doing cut-stem and into doing injections due to the complications of disposal, but we've only been doing injections for about a year, and don't have much to report yet.

    Knotweed treatments

    Leslie Clark replied to Katie Grzesiak's topic in Best Management Practices (BMP) and Treatment

    Any update on this? I'm curious about using the Clearcast cocktail as a cut-stem application. Are you using the same concentration as for spraying?

    Flowering Rush

    Leslie Clark replied to Kip Cronk's topic in Best Management Practices (BMP) and Treatment

    I've been working on a couple of small patches in Keego Harbor in Oakland County with hand removal, with the results of the Lake Minnetonka study in mind, which indicates that really meticulous hand removal can be very effective. In September 2016 I recorded that I removed 5 large heavy bags from a particular site that also has cattail and other emergent plants. I used a spading fork to loosen the soil. There were a lot of floating bulbils to capture, including old 'nests' of brown ones, and I used a kitchen sieve or colander to capture them. For the same site in 2017 I removed only 1 large bag. However, I did the 2017 work in mid-July. It appeared to me that in mid-July, the viable old bubils had pretty much all sprouted, making them visible and identifiable, but the new bulbils were still small and rather firmly attached to the plants. This resulted in very few floaters to be chased down, reducing the odds of spreading it. For my practice sites I was really really meticulous about finding every plant, both new and old in 2017. Follow-up visits later in the summer did not reveal any more plants at those sites. I'm looking forward to evaluating the results of that effort over the next few weeks.

  38. Sarah S.
    Hi everyone, As I gear up for another summer of battling black swallow wort, I thought I'd share what I've tried so far. Last year I was able to control isolated patches of swallow wort by using Round Up poison ivy killer (contains small amounts of triclopyr) by spraying each plant until dripping. I was using 8 ounces of the concentrate in my 1.33 gallon battery sprayer with a bit (maybe 2 oz, I didnt measure) of 80/20 surfactant from tractor supply. That works well for individual plants. Now, I'm back to tackling my giant monoculture. I obtained some used billboards and put them down mid May. I tried sailing grommets with 4 inch landscaping pins, but that didn't hold. I needed something heavier. I've moved to rocks and milk jugs, which I need more of. The billboards seem to be suppressing growth, but I think being that they're white, they're still letting too much light through. I'm going to get more and double up with two layers. The portions of the photos that show no growth is due to the billboard being blown into a tangle from last winter. I just wanted to share since I know many of us are struggling to get this terrible invader under control.

    Some invasive ladybugs feast on other species of ladybugs, but not as much when a kind of toxic aphid is around. View the full article

    Hogweed?

    Claire Peterson replied to Claire Peterson's topic in What is it? Species Identification Help

    Will do, thanks again Katie!
  42. Claire Peterson
    Thanks so much Katie, I will pass this information along to her.

    Four of the images are indeed Japanese knotweed. The fifth (with flowers) is an invasive honeysuckle, likely Lonicera tartarica. Killing knotweed on just the messenger's property likely won't work, as it shares a root system with the neighbor; they will need to work with their neighbor to manage the whole stand together.

    Hogweed?

    Katie Grzesiak replied to Claire Peterson's topic in What is it? Species Identification Help

    Definitely not hogweed, but I don't have a lot of guesses for what it could be either; ask for another photo once it's flowering?

    Hogweed?

    Claire Peterson posted a topic in What is it? Species Identification Help

    From a Facebook message this morning. Doesn't look like but not sure what it could be...thoughts?
