Atrazine APPLICATIONS
Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Maize tolerance is attributed to rapid detoxification by glutathione transferases. Mode of action Selective systemic herbicide, absorbed principally through the roots, but also through the foliage, with translocation acropetally in the xylem and accumulation in the apical meristems and leaves. Uses Pre- and post-emergence control of annual broad-leaved weeds and annual grasses in maize, sorghum, sugar cane, pineapples, chemical fallow, grassland, macadamia nuts, conifers, industrial weed control. In Europe, use is concentrated in maize and sorghum. Used also in combinations with many other herbicides. Phytotoxicity Phytotoxic to many crops, including most vegetables, potatoes, soya beans, and peanuts.
Atrazine ANALYSIS
Product analysis by glc with FID (CIPAC Handbook, 1980, 1A, 1106; FAO Specification (CP/61); AOAC Methods, 1995, 971.08). Residues determined by glc with ECD or FID (K. Ramsteiner et al., J. Assoc. Off. Anal. Chem., 1974, 57, 92; E. Knüsli, Anal. Methods Pestic. Plant Growth Regul., 1972, 6, 600; B. G. Tweedy & R. A. Kahrs, ibid., 1978, 10, 493). In drinking water, by gc with FID (AOAC Methods, 1995, 991.07); dealkylated atrazine can be determined by lc with u.v. detection (AOAC Methods, 1995, 992.14, 10.7.01).
