Date palm (Phoenix dactylifera L.) is one of the most important fruit crops grown in large area in the state of Kuwait.  This study was carried out to evaluate the incidence of various fungal diseases on date palm in major growing areas in state of Kuwait.  Fifty (50) infected samples of date palm were collected from 15 farms (10 farms in Al-Wafra and 5 farms in Al-Abdally).  Microscopic examination and morphological characterization revealed that Chalara paradoxa (synonym = Thielaviopsis paradoxa) and Chalara radicicola are the causal fungal pathogen of black scorch disease.  Information from this study will help scientists to design effective strategies in controlling date palm diseases.
