Plant Disease 92 (10), 1469-1469
Abstract: In the southeastern United States the fungus Raffaelea lauricola has been causing extensive mortality of redbay (Persea borbonia) since 2003. It also infects sassafras (Sassafras albidum) and avocado (Persea americana). Here the susceptibility of California laurel (Umbellularia californica) to the fungus was studied. Seedlings, averaging 73 cm high and 13 mm in diameter were wound inoculated with with spore suspensions and mycelial plugs. Nine of ten seedlings exhibited sapwood discoloration and the fungus was re-isolated from eight of these seedlings.
