deaner, if you have roundup, use it. If not, go to walmart and get Eliminator brand glyphosate. There will not be a problem. Roundup is not highly toxic, and only the surfactant is reputed to cause a decrease in frog populations if used extensively and carelessly. Eliminator brand does not have the surfactant, and is much cheaper. Put a squirt of dishwashing detergent in it so it sticks to the weeds better. Just go for it. I have used various glyphosates, triclopyrs, and other complex salts and have thousands of frogs.
