This study aims to evaluate the cytogenetic effects of Glyphosate (phomac) herbicides, which were evaluated in the root tip meristem cells of Vicia faba. In the V. faba L. root growth test, the herbicides with a control for each group Mitotic index decreased with increasing herbicide concentration at each exposure time. In anaphase - telophase cells, the total percentages of different chromosomal aberrations like stickiness, broken chromosomes, vagrant chromosomes, c-mitosis, D trubed metaphase and anaphase, laggards and micronuclei at high concentration (1 ppm) were calculated as 86%, the total number of chromosome aberration increased as Glyphosate herbicide concentration increased. Micro nucleated cells were observed at different stages of cell cycle.
