Most expensive foaming sewer treatments have this same ingredient. I want to combine this with a foaming agent and fill my sewer pipe.....inexpensively.
Products that could have the same active ingredient as the Casoron 4G Herbicide could have a different formulation of the ingredient or precentage but we do not carry any that are labeled for use in sewer pipes so cannot say for sure. The Casoron label specifically states: Do not apply this product as a sewer treatment. This product is a pre-emergent granule that has to be watered into the soil to create the barrier and be effective.
