Pathogenic Variation in Xanthomonas Albilineans (Ashby) Dowson, the Causal Agent of Leaf-Scald Disease of Sugar Cane

Abstract

The comparative pathogenicity of four isolates of X. albilineans was examined on 13 varieties of sugar cane. The isolates could be differentiated on the basis of their aggressiveness on seven varieties. The significance of varying aggressiveness of isolates in the epiphytology of the disease, and in the screening of varieties, is discussed.
