Abstract

Healthy and diseased shoots were collected from a Eucalyptus tereticornis plantation and from 4- to 6-yr-old coppiced trees in a mixed stand of E. grandis and E. eugenioides. Stem phloem tissue showed necrosis and increased by 42. 8 percent. Infected tissue could be detected easily using Dienes' stain and fluorescence microscopy with aniline blue. It is suggested that the disease is caused by a mycoplasma-like organism
