September 2014: The Connecticut DEEP came to Roseland Lake to control invasive Phragmites on September 9-10, 2014. Plants were sprayed with a product containing imazapyr as the active ingredient. Imazapyr shuts down the plants ability to make food, so the plant uses up its reserves and eventually starves itself out. This takes about 4-6 weeks.
