What effect does Tengard SFR have on swans that eat sprayed grass?


Tengard SFR leaves behind only a small amount of active to kill insects once dry.  It should not affect swans that may eat the grass as they would have to ingest a large amount of actual product in order for it to be harmful.  We would recommend applying when they are not in the area to minimize contact with wet surfaces.
