ملخص: Fusarium wilt of date palm, also known as bayoud, is a major disease in North Africa. In Algeria, the wide range of agro-systems, soil types, genetic diversity of palm plantations and the extent of contamination in diseased areas suggest the need for an integrated plantation-specific control strategy. In areas with disease-free plantations, the regulations on movement of planting material and palm fronds should be accompanied by an educational programme to teach farmers control measures. Primary occurrences in disease-free areas can be curtailed by combining soil fumigation with the introduction of suppressive soil in order to prevent recolonisation by surviving spores of the parasite, and by controlling soil salinity. The genetic variability of cultivars makes it possible to replant affected groves with tolerant, well adapted types. Because of the complex and diverse nature of agro-systems in the oases, the shortcomings of technical support and the limited resources, experimental stations should strive to assist local farmers with ‘massal’ selection rather than to develop sophisticated long-range selection programmes.
