  1. Here's a quick overview of the treatments ISN has found most successful for controlling knotweeds: Milestone (aminopyralid) Faster kill (~3 years), more off-target effects Standard rate (3-7 oz/acre; 0.01%) Using nonionic surfactant (standard rate) Late spring (3-4 ft high) or late summer (at least 60 days before frost) When treating in late summer, it is helpful to do a cut of the plants a month or so in advance ONLY IF safe disposal of the stems is possible At some sites, repeat treatments (spring & summer) may be appropriate, so long as maximum application rates are not reached Not aquatic approved Note: Tree sensitivity issues--some trees will die if their roots mingle with knotweed that is treated with Milestone. Clearcast (imazamox) Acceptable kill (~5 years), fewer off-target effects Cocktail: 5% Clearcast 1-2% Methylated Seed Oil (MSO) Not all MSOs are aquatic-approved!! Check before applying to knotweed in areas with standing water 1-2% glyphosate (aquatic-approved formulation) Best sprayed in late summer/early fall Spraying at least 60 days before the first frost is CRUCIAL--this date will vary by location (for northwest lower MI, it's early August) Aquatic approved (if adjuvants are aquatic-approved) We have applied both of these treatments as either foliar spray or as a "cut stem" application (cutting down stems and filling the stem cavity with herbicide solution), which is a great way to avoid drift and overspray, but is more time-intensive and contains the risk of stem disposal.

    Landing Blitz on Crystal Lake

    until
    ISN is partnering with Benzie Conservation District, the Crystal Lake and Watershed Association, and the Department of Environmental Quality to host a “Landing Blitz” in Benzie County! This event is a collaborative outreach campaign to raise awareness about preventing the spread of aquatic invasive species through recreational boating and related activities. Taking preventative steps (i.e. cleaning your boat and live wells) before moving to another lake can make an incredible difference in the battle against invasive species. Please join us on Saturday, July 1, from noon-3:00pm at the DNR’s new Crystal Lake Boating Access Site, just off of M-115 and Mollineaux Road.Volunteers will be on site to deliver information on how to stop unwanted aquatic hitchhikers. Additionally, we will provide demonstrations on how to properly rinse your boat by utilizing the permanent boat washing station on site, owned and operated by the CLWA. Boaters will be greeted with free outreach materials and goodies (like microfiber towels), while supplies last. This is a wonderful opportunity to take great steps towards protecting our region’s natural ecology – and it takes just a few extra moments on what we are hoping will be a beautiful 4th of July weekend! Help make Benzie County’s “Landing Blitz” a success by taking a break on Crystal Lake! These events are being held all over the state during the first week of July – join the invasive species efforts happening in your region!

    Japanese Knotweed Community Training

    until
    Japanese knotweed, also known as "Michigan bamboo", is a highly invasive plant in our region and it's becoming a major issue for homeowners and land managers. Its incredible root system can damage infrastructure and above ground, it chokes out native vegetation and hurts wildlife habitat. This community training will focus on: How knotweed grows and spreads The best time and methods for controlling knotweed Hands-on demonstrations at a knotweed-infested site Techniques for preventing the spread of knotweed including proper handling of waste. We will begin indoors for a presentation and then venture to a knotweed site for hands-on demonstrations of proper identification and treatment. This training is free and open to anyone with knotweed concerns. Light hors d'oeuvres will be served. RSVPs are required as space is limited. You can register here. When: Saturday, June 3, 2017 - 9:00am-12:00pmWhere: Please meet at West Shore Medical Center, classroom #1 (1465 E. Parkdale Ave., Manistee, MI). Carpooling will be available to our demonstration site, located approximately three miles away.Contact: Emily Cook, ISN Outreach Specialist, (231)941-0960 x20 or email ecook@gtcd.org
