«Bayoud», a vascular wilt disease, has become for more than a century a serious threat to date palm in Moroccan oases. The strategic importance of date palm cultivation to oasis agriculture drives the intensification of date production through new investment projects on soils that are potentially healthy, but very close to infested areas. The success of these investments requires drastic prophylactic and pathogen exclusion measures. In this work, we summarize the main research results to underpin this effort. We analyze the epidemiological situation of Bayoud disease in Morocco and we bring insight to integrated management based on early detection, cartography, and genetic resistance to wall-off the disease and secure the investments in the new date palm growing areas.

Key words: Date palm, Bayoud, early detection, cartography, genetic resistance
