The present study was designed to study the following: 1. Survey of Cherry tomato powdery mildew disease caused by Levellilula taurica at El-Sharkia, El-Ismailia, Giza and Alexandria governorates. 2. Pathogenicity of the causal agent on Cherry tomato plants. 3. Reducing disease incidence and severity of pathogen throughout application of different plant extracts. 4. Chemical control by using some synthetic fungicides at different and alternative application time, single and /or in combination. 5. Biological control by some biocides application. 6. Induction of resistance of cherry tomato plants against powdery mildew by microelements i.e., Fe, Zn and Mn and also some mineral salts as foliar application. 7. Impact of some aforementioned treatments on fruit yield production and some quality parameters of Cherry tomato.
