BENITEZ, Édgar  e  GARCIA, Celsa. The history of research on oil palm bud rot (Elaeis guineensis Jacq.) in Colombia. Agron. colomb. [online]. 2014, vol.32, n.3, pp.390-398. ISSN 0120-9965.  http://dx.doi.org/10.15446/agron.colomb.v32n3.46240.

This article presents an overview of the main results obtained from research on oil palm bud rot. Aetiologic studies with biotic and abiotic approaches were explored, aiming for a model that would help in the understanding of the ethology of this disease. It also discusses how the results of the studies are contradictory and how the arguments for biological causes have not shown progress. Furthermore, the results of measuring the influence of abiotic factors, where there is greater consensus, are discussed; however, there is controversy due to the fact that different researchers placed different weight on the final model of this disease. This situation has led to controls being directed toward potential pathogens associated with the disease, as determined by circumstantial evidence, wherein the positive or negative response to the control may be confused with extrinsic factors such as disease escape or foci formation. Even the role played by the insect Rhynchophorus palmarum (L.) in the death of palms affected by this disease is in doubt. Finally, this paper shows how the process of general disease research has important biases arising from the risk aversion of palm producers or the lack of continuity in results obtained by different research groups.
