Oil palm bud rot in Latin America : Preliminary review of established facts and achievements
Bud rot, type diseases of oil palm affect tens of thousands of hectares of oil palms (Elaeis guineensis Jacq.) in South and Central America. They have destroyed entire estates in Panama, Colombia, Suriname, Brazil and Ecuador. They are therefore holding back the development of oil palm cultivation in Latin America, and all the more so in that the cause remains unknown. Indeed, thirty years after these diseases first wreaked havoc on a large scale, it is still not known whether we are dealing with one or more diseases of infectious origin, or whether it is a physiological disorder. No pathogens or insect vectors have been found so far, despite lengthy research launched in the early 1980s. As knowledge stands at the moment, only genetics look likely to offer a solution in the more or less long term, using traits of resistance transmitted by the native species on the American continent, Elaeis oleifera, to the E. oleifera x E. guineensis interspecific hybrid. The purpose of this review is to look at the different avenues explored during all this research work. Proposals are made for setting up a research network on this subject.
