| Abstract | ||
| The present study has been conducted at the laboratories of Date Palm Research Center to evaluate the inhibition efficiency of plant extract which were Clerodendron inerme, Eucalyptus camaldulensis and Rhus coriaria at three concentrations (0.25, 0.5 and1%) on the radial and dry growth of some pathogenic fungi for date palm.Results of survey successed in isolation different groups of fungi ,and the fungi Alternaria alternata , A. chlamydospora and Ulocladium atrum, were the most abundant amongst isolated fungi, results of plant extracts test proved that Rhus coriaria Ethanolic extracts had the highest average of fungal growth inhibition percentage which were 43.23, 44.59, and 42.84% respectively, as a percentage of radial growth inhibition, and 65.38, 53.13 and 52.23% respectively, as percentage of dry growth inhibition.From obtained results it was clear the increasing of extract concentration (%) correlated positively with the inhibition percentage, against the growth of date palm leaf spot fungal pathogen | ||
