The plants were sprayed with different concentrations of 2, 4-D, Oxyfluorfen, and Glyphosate and their effect on pollen mother cells was studied. The abnormalities percentage increases as the concentrations of herbicide increase. The abnormalities percentage increased from 0.03 to 1.91 at 200 to 500 ppm of 2,4-D, 0.30 to 1.33 at 400 to 800 ppm of Oxyfluorfen and 0.38 to 1.33 at 600 to 1000 ppm of Glyohosate. The abnormalities like laggards, clumping and grouping of chromosomes were observed.
