If you live near the water, I'm sure that you have been enjoying the frog serenade on these nights when we can enjoy having the windows open at night. If you plan to be spraying for weeds anywhere near the water, be careful. Amphibians are very sensitive to glyphosates, the chemical component of Roundup, and all of the generic labels of glyphosates. Fish and aquatic invertebrates are more sensitive to Roundup than terrestrial organisms. Roundup is not registered for aquatic uses and studies of its effects on amphibians indicate it is toxic to them. To control emerged weeds such as cattails use Eraser AQ Aquatic Herbicide. It's safe for the frogs and fish in your water. FELDMANS Farm & Home sells Eraser AQ Aquatic Herbicide in the quart size for $33.99. Use CIDE KICK II AQUA SURFACTANT with the Eraser to help it stick to the plant leaves and you will improve your results. Our gallon size of CIDE KICK AQUA SURFACTANT is $27.99
