Paddy blast, brown leaf spot and bacterial leaf blight of rice are the most devastating diseases of rice worldwide causing serious threats to food security. For the purpose field trials were conducted for the evaluation of different available fungicides at Rice Research Institute, Kala Shah Kaku during season of 2016. Application of different fungicide to control the disease and their effect on paddy yield under field condition were studied. The results showed that fungicide application not only controlled the disease but also improved the paddy yield as compared to control. In this study, Amistar Top 325 SC performed best to control the Paddy blast that leaf to high yield. In the case of Brown leaf spot, application of Switch DF 80 WG revealed the lowest incidence of disease along with highest protection value. Similarly, Nativo was most effective to control the Bacterial Leaf Blight incidence. Conclusively, these chemical can be used to control the studied bacterial and fungal diseases for high paddy yield.
