Environmental fate: 
Animals:Metabolism studies in three different species showed that bentazone was only poorly metabolised, the parent compound being the predominant product. Only small amounts of hydroxylated bentazone metabolites could be detected. No conjugated products were fouSoil:In soil, short-lived hydroxy compounds are first formed, which rapidly undergo further degradation (R. Huber & S. Otto in Rev. Environ. Contam. Toxicol., 137, 111-134). In sunlight, bentazone undergoes rapid degradation, ultimatePlant:In plants, rapidly metabolised to derivatives of anthranilic acid, the principal metabolites being the 6- and 8-hydroxy derivatives, which are conjugated to sugars, forming glycosides.
