title: Studies on optically active pesticides, I synthesis and herbicidal activity of d(+) and 1(-) methyl-2-chloro-3-(4-chlorophenyl)-propionate.
abstract: d(+) and 1(-) Methyl-2-chloro-3-(4-chlorophenyl)-propionate (common name chlorfenprop-methyl; trade mark Bidisin) were prepared and their herbicidal activities studied on Avena fatua L. and Avena sativa L. ("Flämingskrone"). The 1(-) enantiomer was found to be twice as active as the racemate; the d(+) form almost inactive.
