Persistence in and Release of 2,4‐D and Azoxystrobin from Turfgrass Clippings

Jeffries, M. D., Yelverton, F. H., Ahmed, K. A., & Gannon, T. W. (2016, September 29). Journal of Environmental Quality, Vol. 45, pp. 2030–2037.

By: M. Jeffries n, F. Yelverton n, K. Ahmed n & T. Gannon n 

MeSH headings : 2,4-Dichlorophenoxyacetic Acid / analysis; 2,4-Dichlorophenoxyacetic Acid / chemistry; Cynodon; Fungicides, Industrial; Methacrylates; Pesticide Residues / analysis; Pesticide Residues / chemistry; Poaceae; Pyrimidines / analysis; Pyrimidines / chemistry; Soil Pollutants / analysis; Soil Pollutants / chemistry; Strobilurins / analysis; Strobilurins / chemistry
topics (OpenAlex): Turfgrass Adaptation and Management; Pesticide and Herbicide Environmental Studies; Plant and fungal interactions
TL;DR: This research supports the currently recommended practice of returning clippings to the turfgrass stand when mowing because removal of 2,4-D and azoxystrobin in clippments may reduce pest control and cause adverse off-target impacts. (via Semantic Scholar)
