ENVIRONMENTAL FATE

The degradation of (14C) benzoylprop ethyl (Suffix, ethyl N-benzoyl-N-(3,4-dichlorophenyl)-2-aminoprop ionate) in four soils has been studied under laboratory conditions. The major degradation product of benzoylprop ethyl at up to 4 months after treatment was its corresponding carboxylic acid. On further storage this compound became firmly bound to soil before it underwent a slow debenzoylation process which led to the formation of a number of products including N-3,4-dichlorophenylalanine, benzoic acid, 3,4-dichloroaniline (DCA), which was mainly present complexed with humic acids, and other polar products. Although these polar products were not identified, they were probably degradation products of DCA, since they were also formed when DCA was added to soil. No 3,3',4,4'-tetrachloroazobenzene (TCAB) was detected in any of the soils at limits of detectability ranging from 0.01-0.001 ppm. Since N-3,4-dichlorophenylalanine and 3,4-dichloroaniline were transient degradation products of benzoylprop ethyl, the metabolism in soil of radio-labeled samples of these compounds was also studied. In these laboratory experiments the persistence of the herbicide increased as the organic matter content of the soil increased and the time for depletion of half of the applied benzoylprop ethyl varied from 1 week in sandy loam and clay loam soils to 12 weeks in peat soil.

Usage: Herbicide developed by Shell Research Limited. Patents: BP1164160. A selective, post-emergence herbicide.

Application: Selective systemic herbicide, absorbed predominantly by the roots, but also by the leaves, with translocation acropetally. Used mainly against wild oats in winter and spring wheat field at dosage of 0.9-1.5 kg/ha.
