The cytological and developmental effects of the herbicides prometryne Gesagard, trifluralin Treflan and EPTC Eptam were studied in lentil seeds at different concentrations. All herbicides reduced seed germination, seedling growth, and mitotic activity of root-tip cells of lentil and these effects increased as the concentration of all herbicides increased. Trifluralin was most potent in reducing seedling growth and mitotic index, while EPTC showed higher potency in reducing germination percentage and in inducing clastogenic effects which resulted in the formation of different types of aberrations, i.e., C-metaphase, binucleate, tetraploid cells, unequal tripolar anaphase, bridges, lagging, and stickiness of chromosomes
