Brassica napus (Rapeseed) affected by white rust is a major threat in Pakistan causing 60-90% yield losses. Two susceptible varieties of Brassica napus DGL and Oscar were sown in research area of department of Plant Pathology during 2016-17. Eight commercial fungicides were applied to check their efficacy to manage the white rust disease. Two concentrations (0.25% and 0.50%) of each fungicide were applied on weekly interval with hand sprayer separately on each variety. It was concluded that among all fungicides, Swing 72% (Metalaxyl 8% +Mancozeb 64%) was found most effective in reducing the disease incidence. It reduced the disease incidence effectively upto 24.09% followed by Antracol (Propineb 70%) 34.7%.
