New Milfoil Treatment
The Winchendon Springs association was able to treat 9 acres of milfoil infestation with a new product, ProcellaCOR. It is a highly targeted product eﬀective against invasive plants, but safe for native plants. It is considered safer by the EPA than Diquat. Whats more, it is more eﬀective. The New Hampshire DES encourages the use of ProcellaCOR over Diquat. More information can be found on the Solitude Lake Management web site, (solitudelakemanagment.com)
The Winchendon Springs people tell us there has been no regrowth of milfoil as yet in any of the treated areas. This is significant because the manufacturer guarantees the product for 5 years. In other words, if there is a recurrence of weed in a treated area within 5 years of application, the company will pay for re-treatment.
Last year we treated 23 acres of milfoil with Diquat at a cost of $13,000. We have used Diquat for many years now an have not seen a significant reduction in milfoil infestation.
Your board would like to use ProcellaCOR next year. There is a significant cost diﬀerence with the new product that is oﬀset by substantially reduced long term costs. Last year the cost of ProcellaCOR was $1,100 per acre. The estimated cost of treating 25+ acres next year is above $28,000. Spread over 5 years the cost would eventually become $6000 per year, assuming we are treating 25 acres, much less if there is less weed to treat. The board thinks this is a sound investment in the lake’s future. We will be looking at finances and potentially asking for some additional help to meet that goal. Please keep us in mind next spring.
