The Central Region of Cuba has been affected by the yellow leaf syndrome (YLS). During 2005 in Villa Clara were evaluated 3 011,63 hectares in 6 sugarcane enterprises and in Cienfuegos, 2 641,7 hectares were evaluated in 5 enterprises. During 2006 the study included 3 641,92 hectares belonging to 4 enterprises in Villa Clara. It was used refractometric brix in the central midrib and symptoms on leaves, to detect the presence of YLS and a four degrees scale was applied to express the disease severity in field conditions Infected fields in Villa Clara reached 47,1 and 32,6% of incidence during 2005 and 2006 respectively, while in Cienfuegos it was 38,7% during 2005. The presence of the YLS was recorded in 73,6 and 83,1%, during 2005 and 2006, respectively, in evaluated areas belonging to Villa Clara and in 91,4% of the area evaluated in Cienfuegos, which indicates its wide propagation in commercial plantations of sugarcane. Cienfuegos howed higher incidence and severity of YLS, affecting a wide range of varieties, mainly C1051-73, C87-51, C120-78, SP70-1284, C86-12, Co997 and C132-81. It is recommended to continue observing the evolution of the YLS in Cuba, fundamentally in the Central Region of the country and accomplish studies to determine the damages to sugarcane production.
