Conteúdo: | Before discussing the work we have done on the stubborn disease in Morocco and other Mediterranean countries, we take this opportunity to exppress our best thanks to Dr. L. J. Klotz of the University of Califoriia Citrus Experiment Station, Riverside, and to Dr. J. F. L. Childs o  the U. S. Horticultural Field Station, Orlando, Florida. Dr. Klotz frrst visited Morocco in May 1953, and then again in May to June 1957. rr. Childs came to Morocco in May 1955. Their stay in Morocco, the disuussions we had with them, and the letters they wrote us have helped u  a great deal in the study of this disease, which has been recognizedffor only a few years in this part of the world. In november 1949, a ctrus grower in Morocco brought to the attention of the HorticulturaResearch Department the fact that some Washington Navel orange trees had a tendency to produce blossoms all the year through. The fruits were distorted, had a thick, rough peel, and were of no commercial value. Furthermore, the sickest trees had more or less the shape of an oblate spheroid. The condition of the trees was attributed at that time to a bad choice of budwood. It appeared that the budwood of these trees might have come from a clone similar to the one called "Australian" in the United States, which produces an undesirable type of tree. Consequently, growers advised to top-work the trees and progagate with budwood taken from normally growing trees.
