Exotic Milfoil Weed Treatment

Treating for exotic milfoil is an on-going challenge. Without the vigilance of MLPOA and our annual treatment process, exotic milfoil would take over our lake. Our treatment plan for this year is a return to the herbicide “Diquat” which has been applied  in previous years.  Aquatic Control Technology and NHDES have both recommended a return to Diquat due to less than anticipated results from the last 3 years of treatment with 2,4-D and fear of our milfoil developing immunity to 2,4-D.  Water temperature, chemistry and low level currents were the cause of poor results in some treatment areas.

Microsoft Word - 2014 MonomonacLk_TRT_AbtterNotice.docWe are planning to treat all 30 acres of milfoil in Lake Monomonac in early June in accordance with a Permit issued by the NH Division of Pesticide Control.

The following temporary water use restrictions will be imposed on the day of treatment:

No swimming for 24 hours following treatment, within 200 feet of treated areas.
Do Not Use this water for drinking, irrigation or for mixing sprays for agriculture or ornamental plants until further notice. Some irrigation restrictions may be relaxed, as per the pesticide label, at the discretion of the applicator.
These restrictions apply to all intakes within 1,200 feet of treatment area, and to all wells within 50 feet of the treatment area.

Contact Aquatic Control Technology, 11 John Road, Sutton, MA 01590-2509, 508-865-1000, info@aquaticcontroltech.com for information on the release dates of these restrictions or for additional information on the irrigation restrictions.

The shoreline of the lake will be posted with signs warning of the temporary water use restrictions that will be imposed, immediately prior to treatment. If you have any questions concerning treatment, contact Aquatic Control Technology at 508-865-1000 or go to www.aquaticcontroltech.com.

I am also pleased to report that MLPOA applied for and received a State of New Hampshire grant to assist our weed treatment. This grant is for 25% of the cost of treatment. The estimated cost to treat 30 acres is $12,500.  We are fortunate to receive a grant this size for the fifth year in a row.  Obviously New Hampshire is supporting our desire to eradicate the milfoil but we need your support to make it happen. Please send your membership dues.
