ABSTRACT
The sugar beet, Beta vulgaris L. (cv. Early Wonder), was selected as a plant test for the herbicide indaziflam and used to determine the persistence of this herbicide under field conditions in the sugarcane crop under Brazilian conditions. A randomized block design with four treatments was used: weeded control and Indaziflam 75, 100 and 200 g/ha, arranged in a randomized block design with four repetitions. For the determination of persistence, soil samples were taken at sixteen times: 0, 30, 74, 99, 134, 167, 195, 224, 264, 295, 327, 365, 406, 454, 491 and 522 DAT (Days After Treatments). To determine the persistence, the bioassay methodology was used with sugar beet plant test. The persistence in the soil of Indaziflam, as a function of the treatments was, respectively: 365 DAT, 150 g/ha; 454 DAT, 200 g/ha and 491 DAT, 400 g/ha.
