Abstract
Pesticides, especially insecticides, are sprayed on crop plants to
prevent their destruction by insects and other pests. Indoxacarb is one such
insecticide that is regarded as a low-risk pesticide and used on cultivated
plants including many fruits and vegetables. In this study indoxacarb was
evaluated for cytotoxicity and genotoxicity by the Allium cepa assay.
Four dilutions of the recommended dose of indoxacarb were tested on three sets
of A. cepa bulbs which were allowed to undergo rooting in the solution
of indoxacarb. Lowering of mitotic index of the cells of the root apical
meristem relative to control was the parameter used to assess cytotoxicity
while induction of chromosomal aberrations was used as an indicator of
genotoxicity of indoxacarb. Various types of chromosomal aberrations were
noticed in the cells of the roots treated with indoxacarb such as disturbed
prophase, sticky chromosomes, c-metaphase, irregular metaphase, irregular
anaphase, multipolar anaphase, chromosomal bridge, and vagrant chromosomes. The
study clearly demonstrates that all the tested dilutions of indoxacarb are
cytogenotoxic and thus, its use on plants poses a grave risk.
