إنجليزي. Brittle leaf disease of date palms, known in Southern Tunisia since the 1960s, has assumed epidemic proportions from 1986 on. The symptoms are associated with manganese deficiency and the presence of a small double stranded RNA of host origin. Even though no pathogen has yet been found, some observations do not fit a purely abiotic cause of the disease. In particular, affected trees seem to cluster into foci and mineral analyses show no significant differences between the soils of affected and unaffected trees. Further work is required to understand the aetiology of the disease

I sintomi sono associati alla carenza di manganese e alla presenza di un piccolo RNA a doppia elica originato dall'ospite. Sebbene non sia ancora stato ritrovato un agente patogeno, alcune osservazioni non concordano con una causa puramente abiotica della malattia. In particolare, le piante colpite sembrano raggrupparsi in focolai e le analisi dei minerali non evidenziano differenze significative fra i terreni delle piante colpite e non colpite. E' necessario un ulteriore lavoro di ricerca per comprendere l'eziologia della malattia]
