Dicamba was negative in Ames, CHO/HGPRT, and micronucleus assays. It was also negative in an in vitro chromosomal aberration assay with human lymphocytes, with and without S-9, following a 3-hour treatment period in the initial assay. In the confirmatory assay, there was an increase in cells with chromosomal aberrations with S-9, but only at the highest level tested and in the presence of a precipitate and concomitant cytotoxicity. There was also an increase in cells with chromosomal aberrations following a 22-hour treatment period without S-9 at the highest levels tested and with concomitant cytotoxicity. Based on information reported in the Reregistration Eligibility Decision Document (RED) for dicamba, the chemical was negative in an in vitro chromosomal aberration assay with CHO cells. Furthermore, the RED also indicates that dicamba is not carcinogenic based on chronic studies performed with rats and mice. Based on the weight of evidence, the findings of the current study do not alter the conclusion that dicamba does not pose a genotoxic/carcinogenic risk to humans.
