In the present investigation was carried out to find out the impact of Triadimefon (TDM) and hexaconazole (HEX) triazole fungicides on the leaf anatomy of Radish (Raphanus sativus L.) The plant was treated with one litre of aqueous solution containing 20 mg^-1 triadimefon (TDM) and 20mg^-1 hexaconazole (HEX) on 23,35 and 53, days after sowing (DAS) by soil drenching. The plants were harvested on 30, 45 and 60 days after sowing. The total leaf area, thickness of leaf, number of stomata in lower epidermis, stomatal pore length and width were observed in both control and treatments. Leaves treated with TDM and HEX showed several variations in the anatomical characteristics when compared to the leaves of the untreated control plant of Raphanus sativus.
