John, my grandmother used powdered DDT in the garden and had no ill effects from it to. Why isn't it on the market now?
When I went thru the class for my applicators license, they said the label was the law. I can't agree with using something that is NOT labeled for pond use in the pond.
Just like my grandmother, using it may be OK and then again maybe not. I don't want to tell someone to use something that might cause harm, or is illegal.
