Debra from Prattville, Alabama writes
Ferti-lome Weed Free Zone should not be used near fish ponds because according to the product label this pesticide is toxic to fish and aquatic invertebrates and may adversely affect non-target plants. To protect the environment, do not allow pesticide to enter or runoff into storm drains, drainage ditches, gutters, or surface waters.
