In 2014, the EPA granted GCSAA's request for the extension of the end-use date for fenamiphos (Nemacur/Bayer).
Golf course superintendents have until Oct. 6, 2017, to use existing stocks of Nemacur, an organophosphate-class chemical, which is used to control root-knot, root-lesion, sting, lance and ring nematodes.
The extension amounted to a three-year reprieve for turfgrass managers, who were previously staring down an Oct. 6, 2014, cutoff for using existing stocks of Nemacur.
Golf course superintendents must deplete their existing stocks by this deadline. Nemacur is used to control the major genera of nematodes attacking turfgrass including root knot, root lesion, sting, lane and rink nematodes.
The EPA made this decision official by publishing a notice in the Federal Register.
