Summary:The morphological and molecular characterization using primers EryF and EryR confirmed the associated pathogen with collected samples of tomato powdery mildew as Oidium neolycopersici. Incubation and latent period of the pathogen under in vitro was 4 and 5 days, respectively, however it was 5 days for both under in vivo. Effect of weather variables on the disease development in March 30th and August 30th transplanted crop showed that low temperature and high relative humidity were most favourable factors for disease development. The studies on colonization behavior of the pathogen showed that tissue colonization was directly proportional to the disease severity.
