This was a good opportunity to hold the first international conference on so-called “virus” diseases of citrus, of which many had been studied in California, if not in Florida. Maladies such as Tristeza, Psorosis, Concave Gum and Blind Pocket, Crinkly leaf and Infectious variegation, Stubborn, Xyloporosis and Cachexia, Exocortis, and Vein enation had been shown to be transmissible by graft-inoculation. and were, for this reason, thought to be of viral nature, but not a single causal agent had yet been identified, mechanically transmitted, purified, or even seen in the electron microscope PB IOCV SN 2313-5123 YR 2010 FD 2010 LK http://hdl.handle.net/20.500.11939/7718 UL http://hdl.handle.net/20.500.11939/7718 LA en NO Bové, J.
