I've also used terrestrial herbicides for catttails when I didn't have the aquatic ones on hand and never saw any issues with the frogs or any dead fish. The most detrimental thing I have noticed to amphibians are Great Blue Herons and largemouth and smallmouth bass. I no longer have largemouths and keep the herons out of the water with staked lines. Whalla! Lots of frogs.
That said I do use a Shorekill for my cattails now.
Is it possible Kelly that part of the reason for the precautions on the terrestrial herbicides is due to a lack of testing which is expensive? I do know that is the case with some chemicals and compounds we would like to use in aquaculture. It's just that it costs thousands of dollars to get the testing done and it's a long time consuming process to approve them.
