>Dow AgroSciences Moves to Discontinue Residential Uses of Clopyralid in
>              INDIANAPOLIS -- In response to initiatives by California
>  makers of clopyralid-containing herbicides Dow AgroSciences and
>  Chemical Company are notifying the U.S. Environmental Protection Agency
>  changes to product labels that will prohibit future use on California
>  residential lawns.
>              The companies have also requested lawn care operators and
>  and distributors who offer clopyralid-containing herbicides not to sell
>  use them on residential lawns in California.
>              These steps are being taken to address concerns expressed
>by the
>  California Department of Pesticide Regulations (DPR) and others over
>  reports of trace levels of clopyralid in compost which may damage some
>  sensitive plants (e.g., tomatoes, potatoes, peas, beans and
>  especially when compost is used without properly mixing it with soil.
>              "We are not aware of any documented cases of damage to
>  plants in California," said Dr. Bryan L. Stuart, Dow AgroSciences state
>  affairs manager.  "We believe this is a problem of misuse, but we want
>  cooperate with DPR and address this matter expeditiously."
>              Composting of grass clippings from residential lawns has
>  identified by state regulators as a primary source of trace level
>  clopyralid residues in compost.
>              Dow AgroSciences clopyralid herbicides have label
>restrictions on
>  using compost containing grass clippings treated with the product.  But
>  homeowners using professional lawn care services may not have been
>  informed that clopyralid was used or not have known that restrictions
>  apply.
>              In some California locations, curbside recycling of grass
>  is common practice, and many localities promote composting in response
>  state laws mandating an ongoing reduction in the amount of waste sent
>  landfills.
>              Professionals in the lawn and turf care industry expressed
>  for the use changes initiated by clopyralid's makers.
>              "We applaud this step taken by the makers of clopyralid,"
>said Bryan
>  Thompson of Landscape Pest Management in Anaheim, "as an effective
>  of addressing public concerns while maintaining essential uses of these
>  products."
>              Clopyralid-containing herbicides are the product of choice
>  controlling invasive or noxious weeds such as yellow starthistle.
>  starthistle can be harmful to livestock, chokes out native plant
>  and makes land unusable for recreation, agriculture or as wildlife
>  habitat.
>              According to the California Department of Food and
>Agriculture, 12-
>  to 20-million acres, or 20 percent of the state, have dangerous yellow
>  starthistle infestations.
>              California agricultural leaders also stressed the
>importance of
>  clopyralid to their operations.
>              "California agriculture has a vital need for clopyralid
>  said Paul Wenger, vice president of the California Farm Bureau.  "We
>  committing to stewarding these products to ensure their safe and proper
>  use."
>              Clopyralid is a herbicide used by farmers, foresters,
>ranchers, golf
>  course managers, parks and recreation professionals and others to
>  hard-to-manage and invasive weeds.  Products containing clopyralid have
>  been on the U.S. market for more than 15 years and have been registered
>  California since 1997.
>              In a recent press release (March 27), the California DPR
>  clopyralid as "a low-toxicity chemical that poses little hazard to
>  animals and most vegetation."
