It has been sixteen days since the lake was treated. This morning Will Stevenson from Lycott Environmental took me for a brief tour around the lake. We looked for milfoil, and found no healthy plants. We saw plenty of very sick looking stalks with their leaves mostly missing, and quite a few floating plants and stem fragments, clearly dead.
This is not to say that there may not be some surviving milfoil plants in the lake, nor that some may return later. Also this informal turn around the lake can not substitute for a comprehensive scientific survey, which will be performed in September. It is far too early to declare victory.
We have been told that the effects of the triclopyr will be seen in the first four to six weeks. It is taken in by the plants right away, in the first hours and days while its concentration is high. Then over time, like a slow acting poison, it takes effect. Hopefully, this is what we are seeing now.
We have spoken with some people around the lake who have said that they thought that the milfoil was dying. Many more have asked us whether the treatment was working, and we have tried to sound hopeful. It has seemed to us that there was no milfoil in places where it had been plentiful before. We are glad to have Will come and share his informed observations. Lycott manages aquatic nuisances in more than 300 lakes. Will was clearly pleased. I trust his educated and experienced opinion.
