I know I'll probably catch hell for this but I've used Round up on shoreline plants with no problems but I did add a surfactant. The resident heron kills more frogs and fish than anything I can apply!
I haven't applied anything this year and I've got hundreds of dead tadpoles in the biggest pond. It's either the smallmouth of 5 to 7 inches smacking them but not eating them as they are too big to swallow, or the bluegills on the beds don't tolerate them in the area. The dead tadpoles are the most numerous in the area where the bluegills are bedding, but the smallies like to hang out in the area too for some reason. They bgs are all males so it can't be because of bluegill fry.
