Property Owners
If you think you have Japanese Knotweed on your property, do not dig up the plant, as knotweed can spread roots several feet deep and over 10 feet across - and tiny root fragments can start new plants (there is no safe way to dispose the roots). Herbicide can eradicate knotweed if performed optimally. It is best to not cut down the knotweed so large canes can be injected with glyphosate, a very effective treatment. If you do cut down knotweed canes, do so prior to June, so there is enough regrowth to allow spraying, and make sure the canes are thoroughly dried out in the sun before discarding them.
Herbicide treatment should only be done after the knotweed starts to flower, when it is taking nutrients (and herbicide) to the root system, and before the first hard frost (August through early October in the Adirondacks). In New York, property owners are permitted to apply non-restricted herbicide on their own property. If you treat knotweed on your own property and do not have an injection gun, consider cutting the knotweed prior to June, then spray the leaves with 5% glyphosate (e.g. diluted Accord XRT II) in August or September.
If your property is in the Adirondack Park consider having the Regional Inlet Invasive Plant Program (RIIPP) help eradicate the knotweed. Check out the RIIPP sheet, and slide show. There is no cost to property owner by the RIIPP, though tax-deductible donations are essential for these efforts to continue.
For 2011 and 2012 we are fortunate to receive grant funds from the Adirondack Park Invasive Plant Program. However, donations are needed to fund all our efforts for 2013.
The first step is to contact the Invasive Plant Coordinator (IPC) for your area. IPCs include:
Blue Mountain Lake Ellen Collins
Chestertown Jan McCann
Garnet Lake Bob Manning and Roy Keats
Indian Lake Terry DeArmas
Inlet/Eagle Bay/Big Moose Patty Wittmeyer
Lake Piseco Katy Weil
Lake Placid Larry Master
Long Lake Chuck Taylor
Lower Hamilton County (Benson/Hope/Lake Pleasant/Morehouse/Speculator/Wells) Elizabeth Mangle
North Creek/North River Judy Brown and Evelyn Greene
Saranac Lake Leslie Karasin
Tupper Lake Scott Chartier
Warrensburg John Wolfken
If there is no Invasive Plant Coordinator (IPC) for your town/area, please consider volunteering to be an IPC for your area. Contact Doug Johnson or Patty Wittmeyer if you are interested in volunteering.
You will need review the first page of the pesticide label for Accord, sign the appropriate Permission Form depending on your area
Inlet/Chestertown/Garnet Lake/North Creek/North River/Warrensburg/Town of Webb form;
Blue Mt Lake/Indian Lake/Lake Placid/North Creek/Saranac Lake/Tupper Lake form; or
Lake Piseco/Speculator/Lower Hamilton County form
and if knotweed is within 100 feet of wetlands (marsh/bog) (see part 578 of APA Rules & Regulations) also sign page 6 of the APA form. The signed forms should be given/sent to your IPC. Then arrange to have the IPC review where the knotweed is on your property. The IPC will coordinate with the pesticide applicator to hopefully treat the knotweed in August or September. There is no guarantee that the property will be treated. The first treatment usually kills over 90% of the knotweed, and a second treatment (the next year) usually kills the rest, with a third year treatment sometimes needed. The knotweed will start to look sick about a week after treatment. You should not cut down knotweed for at least two weeks after it is treated so the pesticide will be taken down to the root system. It is best to leave the knotweed in place after treatment, in which case a second treatment can be done about four week later to plants that were missed.
Please make tax-deductible donations payable to: Town of Inlet, Invasive Plant Control Fund; and mail to: Town of Inlet PO Box 179, Inlet, NY 13360 with your name, phone, address, and e-mail. Contact clerk@inletny.com (315) 357-5771 with questions.
