Navjot works with diseases of wheat such as Stagonospora nodorum blotch and Fusarium head blight. Her dissertation research focuses on characterizing genetic diversity and fungicide resistance in populations of Parastagonospora nodorum, the causal agent of Stagonosopora nodorum blotch in wheat. Specific objectives of my project are to quantify sensitivity of P. nodorum to quinone outside inhibitor (QoI) fungicides, monitor P. nodorum populations for the presence of a mutation conferring fungicide resistance using a pyrosequencing approach, and characterize the population structure of the pathogen in Virginia. The overall goal of this project is to better understand the biology of this pathogen so that more effective disease management approaches can be developed for Stagonospora nodorum blotch. The fungicide resistance study, for instance, will provide growers with an information about the current efficacy of fungicides for management of this disease, and fungicide resistance monitoring will provide insight into the likely future efficacy of specific fungicide modes of action.
