ABSTRACT
The present study was designed to evaluate seven different foliar fungicides such as Cholorothalonyl+metalyxl @ 2000 ml/ha; Pyraclostrobin @ 375 ml/ha; Sulphur @ 2500 g/ha; Diphenoconazole @ 375 ml/ha; Tubiconazole+trifloxystrobin @ 303 g/ha, Polyram DF @ 625 g/ha and Propiconazole @ 625 g/ha for the management of leaf rust of wheat in Research Area of Plant Pathology, Hafiz Abad Research Station, B.Z.U. Bahadar Sub-Campus, Layyah, during crop seasons 2018-2019 and 2019-2020 in Randomized Complete Block Design (RCBD) with three replications. Statistically significant (P<0.05) disease control was observed by Propiconazole (29.30 %) in the first crop season 2018-2019 and 28.50% in the second crop season 2019-2020, followed by Polyram DF (27.60% and 26.30%), Tubiconazole+trifloxystrobin (21.50% and 26.30%), Diphenoconazole (23.30 and 22.57), Sulphur (25.38, 24.50), Pyraclostrobin (19.57 and 18.38), Cholorothalonyl+metalyxl (18.30 and 16.30) and control (0%) during both successive seasons. The maximum number of grains per spike was recorded by Propiconazole (48.3 and 45.40) and Polyram DF (47.3 and 44.50), followed by Tubiconazole+trifloxystrobin, Diphenoconazole, Sulphur, Pyraclostrobin, Cholorothalonyl+metalyxl as compared to control. Highly Significant (P<0.05) 1000-grain weights were recorded by Propiconazole (42.06 g and 40.60 g) followed by Polyram DF (41.49 g and 39.13 g), Tubiconazole+trifloxystrobin (39.39 g and 37.70 g), Diphenoconazole (36.70 g and 35.17 g), Sulphur (34.15 g and 33.50 g), Pyraclostrobin (32.46 g and 31.57 g) and Cholorothalonyl+metalyxl (30.70 g and 29.38 g). All fungicides proved most effective for controlling leaf rust severity in semi-arid region of district Layyah.
