Sugarcane (Saccharum officinarum L.) is an important industrial, monocotyledonous perennial cash crop. Sugarcane brown rust (Puccinia melanocephela Syd. & P. Syd) is one of the most devastating diseases. Sugar cane brown rust is new for Ethiopia and currently only fincha sugar Estate is affected. The current study was carried out to evaluate the efficiency of different fungicides (Opera, Tilt, Natura, Defender, Diprocon and Noble) with three times spray frequencies and their impact on yield and yield components under field conditions in Finchaa Sugar Estate, Ethiopia, during the main cropping season of 2016. For the management of sugarcane brown rust disease, seven treatments were arranged in randomized complete block design with three replications on sugarcane cultivated fields at Finchaa Sugar Estate. The statistical analysis showed that significant differences among treatments in sugarcane brown rust disease incidence, severity. Sugarcane brown rust incidence and severity were highest in the control plots compared to the fungicides sprayed plots. The highest severity value resulted in the lowest cane yield of sugarcane 26.26 t/ha in the control plots compared to a highest yield of 78.27 t/ha from sprayed plots with Opera fungicide and 64.9 t/ha from plots treated with Natura fungicide . Economic analysis revealed that the highest rate of return of 5751 birr was obtained from fungicide Opera and the highest net benefit 55559 birr again from Opera foliar spray treatment. The results of the present study revealed that the novel possibility of using foliar spray treatments which was found to be effective in decreasing sugarcane brown rust symptoms in sugarcane plants in Finchaa Sugar Estate and also increased yield. Further, the effective and feasible management options need to be developed on sugarcane brown rust disease in the country.
