Abstract
The genotoxic effects of the pesticides, monocrotophos and endosulphan , have been studied using root meristems of Allium cepa after 24 and 4 8h exposure to the test chemical. Monocrotophos treatment results in g reater chromosomal break than endosulphan, with a reduction in mitotic index. Both chromosomal and mitotic abnormalities were encountered at all concentrations ranging from 0.2 to 5.0 ppm. Reduction in staining and chromatid breaks with higher concentration suggested clastogenic action of these compounds.
