| Abstract/Contents: | Discusses research at Penn State University to identify and study clopyralid contamination in their composting program. States that the source of the contamination was grass debris which had been accidentally swept up along with the leaves used for compost. Since the discovery of the contamination, Penn State stopped using Confront and Millenium (two products containing clopyralid) for turf applications. Studies show that "given certain conditions, clopyralid can persist for more than two years after application and incorporation into the soil." Stresses that "one of the most significant observations...is that symptoms are often not expressed until about four weeks after transplanting from greenhouse to field, which raises questions regarding the value of short-term bioassays for detection." Suggests that "given the high water solubility of clopyralid, there is reason to suspect that that irrigation methods and frequency may play a role in the uptake, and eventual expression, of herbicide toxicity." |
