SUMMARY A strain of the rust fungus Puccinia chondrillina introduced into Australia in 1971 for the biological control of skeleton weed, Chondrilla juncea , attacked only the narrow‐leaf form of this weed. Studies were, therefore, undertaken in the Mediterranean region to discover strains of the rust which will attack the other two Australian forms of skeleton weed, intermediate‐ and broad‐leaf. Several strains of the rust were found to be highly virulent against the intermediate form. One of these strains from Manisa, western Turkey, was both highly specific to its host and safe for use as a biological control agent. This strain has recently been introduced into Australia for the control of the intermediate form of Chondrilla.
