Among the harmful plants recorded in Cuba Leucaena leucocephala (Lam.) de Wit is described due to its invasive nature in open areas of secondary or semi-natural vegetation in various crops. The work was carried out with the objective of determining the spatial and temporal distribution of Leucaena leucocephala in sugarcane plantations in Cuba. For the study, a survey of the species was carried out and the frequency of appearance between the years 2007-2020 was determined. The spatial distribution by zones was realized with the professional MapInfo Geographic Information System version 12.5. The results describe that in the evaluated period the frequency of appearance of L. leucocephala showed an ascending dynamic over time after its appearance in 2011 and was classified as Accidental with values below 25 %. The presence of L. leucocephala is reported in 39 Sugar Agroindustrial Companies, with greater intensity in the eastern zone of Cuba. The Argelia Libre company of Las Tunas province presented the highest values of frequency of occurrence (59.2 %) classified in the moderately frequent category. [ABSTRACT FROM AUTHOR]
