A good time to proactively treat curlyleaf CLPW is in fall using a Fluridone based product at at 10-11ppb as noted by esshup. Curlyleaf starts growing in late summer - early Fall and then plants sit relatively dormant late Fall and winter when the water temp drops below 50F. . Then in early spring as water reaches 50F-55F it continues growing. The Fall low dosage of Fluridone will persist through winter to keep killing/suppressing CLPW. In early spring a 1/2 dose 5ppm can be applied to enhance the remaining Fluridone to knock out the plants that were not killed in the Fall application.
