1. PP 0E7723. (EPA-HQ-OPP-2010-0471). IR-4, 500 College Road East, Suite 201W, Princeton, NJ 08540, proposes to establish tolerances in 40 CFR part 180 for residues of the insecticide novaluron N-[[[3-chloro-4-[1,1,2-trifluoro-2-trifluoromethoxy)ethoxy]phenyl] amino]carbonyl]-2,6-difluorobenzamide, in or on corn, sweet, kernals plus cob with husks removed at 0.05 parts per million (ppm); corn, sweet, forage at 20 ppm; and corn, sweet, stover at 50 ppm. Makhteshim-Agan of North America, Inc., 4515 Falls of Neuse Road, Raleigh, NC 27609, is the manufacturer and basic registrant of novaluron. Makhteshim-Agan of North America, Inc., prepared and summarized the following information in support of the subject pesticide petition for novaluron. Adequate analytical enforcement methods, gas chromatography/electron capture detector (GC/ECD) and a high performance liquid chromatography/ultraviolet method (HPLC/UV) for enforcing tolerances of novaluron residues in or on different matrices are available, as published in the Federal Register of January 27, 2010 (75 FR 4274) (FRL-8807-2). A method validation was conducted both prior to sample analysis and concurrently with sample analysis, determining that the method recoveries were in the range. The limit of quantitation (LOQ) for the method in K+CWHR, forage and stover was calculated to be 0.040, 0.052 and 0.049 ppm, respectively. The lowest level of method validation (LLMV) for novaluron in corn forage, stover and K+CWHR was 0.05 ppm. Contact: Laura Nollen, [phone], e-mail address: [e-mail].
