Abstract

The differential phytotoxicity of an unidentified amiben conjugate (hereinafter referred to as amiben-X), obtained from giant foxtail (Setaria faberii Herrm.) treated with 3-amino-2,5-dichlorobenzoic acid (amiben) was tested in several plant species. Concentrations of amiben-X up to 10 ppm had no effect on radicle elongation in seedlings of soybean (Glycine max (L.) Merr.) or ivyleaf morningglory (Ipomoea hederacea (L.) Jacq.). Giant foxtail radicles were inhibited about 35% at 10 ppm. Amiben, amiben-X, and N-(3-carboxy-2,5-dichlorophenyl)-glucosylamine (hereinafter referred to as N-glucosyl amiben) were detected in seedling tissues of the three above species treated for 24 hr with 20 ppm amiben-X. The growth response of the plants to amiben-X probably resulted from the action of the amiben released by plant hydrolytic activity on amiben-X; amiben-X itself is considered to be relatively nonphytotoxic.
