Abstract:
Date-palm leaf spot disease was observed on July 2004 in some inspected localities belong to certain governorates. The isolation procedures yielded different Alternaria spp. isolates which were capable of inducing the same disease through the pathogenicity test. In vitro control studies confirmed that Trichoderma spp., Bacillus spp., garlic and camphor extracts as well as Kema-Z and Cure-Plus were able to control the pathogen's mycelial growth and suppress its spore germination. Cure-Plus, Kema-Z and Trichoderma spp. decreased the severity of the leaf spot disease when investigated in the field trials.
