The composting industry is plagued by the lasting effects of certain chemical broadleaf weed killers that can survive the composting process and continue to negatively affect plants grown in such compost. These persistent herbicides have active chemical ingredients that can persist on treated vegetation even after composting.

The USCC recognizes the threat these insidious chemicals pose to our compost manufacturers and the end users of compost products that may contain them.
