摘要：Authors Robert Ali Brac de La Perrière , Abderahmane Benkhalifa Unité de Recherches sur les Zones Arides BP 119, Alger, Algérie. Page(s) : 119-28 Published in: 1991 The history of date palm fusariosis propagation in Algeria is followed up through three scientific surveys under-taken in 1926, 1947 and 1970. Further surveys carried out in the 1980s have enabled the data on Bayoud’s disease to be brought up to date. Although the eastern perimeter of fusariosis had been limited to Ghardaia for the past twenty-five years, today 50 % or the date-palm growing districts to the west of this are now infected. There is no systematic data collection on either sources or means of halting the spread of this epiphytic disease which is rapidly gaining ground from one community to the next. Analysis of various aspects of a large number of date palms sampled along with field surveys provide valuable information as to selection of the most resistant cultivars. The recent upheaval in Saharan agriculture must also be considered in the struggle to rid the date palm of this fatal disease.
