I appreciate you sharing your knowledge John, in the past few threads you have posted I have learned some valuable things.
From what I have read on Shore-Klear Plus it contains a surfacant so I should be covered in that regard. The Shore-Klear (non "plus") doesn't contain a surfacant. As you mentioned, the spatterdock seems to thrive in shallow water, but not in deep water. I find that helpful because it helps me identify which parts of my pond are deeper and which are shallower. I realize I have waited too late in the year to apply glyphosate to my spatterdock before it goes dormant. Therefore do you think it would be best for me to wait until next summer to apply it or go ahead and apply it even though the plants will be dormant by the time I apply. The manufacturer recommended applying in late summer or fall. Either way I can use my Weed Razer to cut out the spatterdock where I do not want it. The reason I am so interested in glyphosate is because when using the weed razer the plants start growing back immediately after being cut and within a month have fully grown back.
