Carbaryl ANALYSIS
Product analysis by i.r. spectroscopy (AOAC Methods, 1995, 976.04; CIPAC Handbook, 1970, 1, 185; 1980, 1A, 1113; FAO Specification (CP/55)) or by hplc (G. W. Sheehan, Anal. Methods Pestic. Plant Growth Regul., 1984, 13, 157). Residues determined by glc (ibid., 1972, 6, 478; Man. Pestic. Residue Anal., 1987, I, 6; Anal. Methods Residues Pestic., 1988, Part I, M2, M13; AOAC Methods, 1995, 975.40; A. Ambrus et al., J. Assoc. Off. Anal. Chem., 1981, 64, 733), by hplc (AOAC Methods, 1995, 985.23), by colorimetry (ibid., 964.18) or by tlc (ibid., 968.26). For methods in drinking water, see AOAC Methods, 1995, 991.06.
