I am sure that everyone has noticed that salvinia is continuing to spread and people are out spraying it to get it under control. When i was hunting the maurepas swamp, we would spray it also and found out that, if it is sprayed too early (October), it will come back and be just as thick as if you didn't spray it. We would always wait until mid to late November (temps. are colder) to spray it and it would not come back until the next year.
