Suppression of Japanese stiltgrass and arthraxon and non-target response using PRE herbicides

A wet meadow infested with arthraxon (Arthraxon hispidus) and Japanese stiltgrass (Microstegium vimineum) was treated PRE with pendimethalin (standard) and new aquatic-labeled herbicides (flumioxazin and bispyribac). Flumioxazin was as effective as pendimethalin, and provides hope of having an aquatic-labeled product for PRE applications to problem annual weeds.
