Hey all. I have a customer who is convinced one of our Fiesta applications killed the fish in his small garden pond last year. We spot sprayed some buttercup 6-10 ft away on a non windy day and apparently the fish died immediately after. Nothing was said by the customer until now, several months later. At the same time, the water in his pond somehow turned clear. We advertise all our products as Children and Pet Friendly so this is very upsetting to hear especially since Fiesta claims their products are safe for pets and people. I would like to know if there is any research proving this could occur? I would appreciate any helpful feedback. Thanks!
