Abstract
Fungicides are agrochemicals that are specifically designed to minimize agronomic loss and increases economic profit. But such chemicals degrade at a slow rate and may become persistent in the soil causing natural contamination. These fungicides also can exert genotoxic, cytotoxic and phytotoxic effect on target plants. Such detrimental effect may extend to other non targeted plants and to other biotic species causing ecological imbalance. Different concentrations of Ambucrop fungicide (25 ppm, 50 ppm, 75 ppm and 100 ppm) exerted negative impact on the Mitotic index of root tip cells of Allium cepa (2n=16) with increasing the abnormality index as compared to the control. The cytotoxic effect increased not only with increasing the concentration of Ambucrop fungicide, but also on the duration of the treatment.
