.........I have found out that gly will supress most noxious plants at 1/10 the recommended dosage. Monsanto, et al, trying to make an extra (billion)bucks.
most people think if they dont get immediate results, increase the dosage....when actually all that is needed is a decent surfactant, which brings up a whole nother story.....my neighbor who is fairly knowledgeable about such things (as is pond frog BTW) found that several premium surfactants which cost mucho $$ are merely pine sol w/ some fatty acids.
many of the over the counter things like ortho weed-b-gone have the right stuff but at low percentages, but adding a good surfactant to them in the sprayer makes them stick and effective. regular dish soap is no good, but probably better than nothin.
