In this study, the cytogenetic effects of afugan were investigated in root tip cells of Allium cepa L. EC50 value of this fungicide was determined as 40 ppm using root growth inhibition test and then the roots of Allium cepa were treated with 10, 20, 40 and 60 ppm concentrations for 12, 24 and 48 h. Mitotic index, mitotic phase frequencies and mitotic abnormalities were determined for each concentration and treatment period. The most common types of abnormality are stickiness, c-mitosis, bridges, lagging chromosomes, fragments, multipolarity and micronucleated cells.
