Isoproturon APPLICATIONS
Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Mode of action Selective systemic herbicide, absorbed by the roots and leaves, with translocation. Uses Pre- and post-emergence control of annual grasses (Alopecurus myosuroides, Apera spica-venti, Avena fatua and Poa annua) and many annual broad-leaved weeds in spring and winter wheat (except durum wheat), spring and winter barley, winter rye, and triticale, at 1.0-1.5 kg a.i./ha.

Isoproturon ANALYSIS
Product analysis by hplc (CIPAC Handbook, 1992, E, 110-115; Anal. Methods Pestic. Plant Growth Regul., 1982, 12) or by titration of the dimethylamine liberated on hydrolysis. Residues determined by glc (Man. Pestic. Anal. Deutsche Forschungsgemeinschaft, 1978, 1, 241; Anal. Methods of Pesticide Residues in Foodstuffs, General Inspectorate for Health Protection, Netherlands, June 1996).
