FireIsHot: Myriophyllum species seem to be more sensitive to treatments compared to coontail; i.e. they respond very readily to fluridone, endothal and some 2,4-D products. Coontail respondes to all but the later, but higher concentrations and durations are often required.

Mully: I don't check the board too often during this time of the year. Shoot me an email with aerial directions to the pond so I can scope it from above (I'd need the direction in degrees and distance from a specific road-intersection); and also a response to the previous questions.

To what extent does the pond's water exchange/discharge over a 5-day period? 10%? 20%? 50% transition?
Is there any desirable aquatic vegetation present that you want to keep?
