Severity of Young Tree Decline of Citrus Independent of Incidence of Xyloporosis. A. W. Feldman, Professor, University of Florida, Agricultural Research and Education Center, Lake Alfred 33850. R. W. Hanks, Associate Professor, University of Florida, Agricultural Research and Education Center, Lake Alfred 33850. Plant Dis. 64:769-771. Copyright 1980 American Phytopathological Society.

Xyloporosis was found in 46 of 110 healthy and 55 of 113 citrus trees affected by young tree decline (YTD) in 21 groves in the major citrus-producing areas of Florida. Annual rate of tree loss from YTD varied considerably among groves, and there was no evidence that additional stresses induced by xyloporosis either increased the rate of tree loss or accelerated the development of symptoms in YTD-affected trees.
