ABSTRACT
BUD rot (BR) is the most serious disease of oil palm in Latin America; in Equator has caused more than 150 million USD of losses. The aim of this work was to determine the incidence, progression and disease intensity of BR in E. guineensis. Incidence and disease progression was determined from data of oil palm enterprises: Palesema, PDA, Palpailón, Energy & Palma y Alespalma during 2006-2013. Disease intensity was determined at 2013. Incidence was 66.75 % and disease intensity was 46 %. Based on projections of accumulative incidence a polynomial equation was built that predicted 78.30 % of cumulative incidence for 2014, indicating exponential growth of BR from 2009 to 2013. Magnitude of damages based on incidence, disease progression and infection index indicated the occurrence of a lethal form of BR in San Lorenzo, province of Esmeraldas, Equator.
