Abstract

A rapid method is described, based on the reaction to a phytotoxin produced by Corticium salmonicolor. Provenances of 11 species (1 each of Eucalyptus microcorys, E. deglupta, E. saligna and E. tessellaris2 each of E. camaldulensis, E. urophylla, E. resinifera, E. pellita and E. brassianaand 4 each of E. grandis and E. tereticornis) were screened using the technique. Significant variation in susceptibility was identified. E. resinifera (no. 13318) was found to be moderately resistant
