A Review of Lasiodiplodia theobromae with Particular Reference to its Occurrence on Coniferous Seeds

SYNOPSIS

The fungal pathogen Lasiodiplodia theobromae has been associated with numerous plant diseases on a wide variety of hosts. Conifers seem to be particularly susceptible to infection, although the true parasitic status of the fungus is still largely unresolved. In South Africa, L. theobromae is associated with discolouration and reduced germination of Pinus elliottii seeds. The mode of seed infection is, however, still unclear. This review attempts to critically summarise current knowledge pertaining to infection of coniferous species by L. theobromae, with special emphasis on its ability to act as a seedborne pathogen and means of controlling it.
