Factors Affecting Epidemiology of Bacterial Fasciation of Chrysanthemum maximum. K. A. Oduro, Graduate Student, University of California, Riverside, CA 92502; Phytopathology 65:719-721. Accepted for publication 18 February 1975. DOI: 10.1094/Phyto-65-719.

The severity of bacterial fasciation of Chrysanthemum maximum (which is caused by Corynebacterium fascians) appeared to increase with the length of time plants are diseased, and with the removal of the apical buds. Garden pea seedlings responded rapidly to the disease in greenhouse studies. Since daisy root divisions used for propagation were the main sources of inoculum in the field, the use of clean planting materials for control is reemphasized.
