I live on the South Texas coast and have Floratam on my lawn. I’ve been dealing with a fungus on my yard, and was wondering if this product is safe to use? I have tried using Bayer fungus control (granules) in the past and have had no luck. I really would like to try this if it’s possible? Need your help. Thanks
