Abstract
The ability of Anguina tritici to act as a vector for Clavibacter toxicus in wheat was determined in a pot experiment. Using galls colonised with C. toxicus from Lolium rigidumas inoculum, gall production by A. tritici was reduced and a small proportion of galls was colonised by C. toxicus. These observations further confirm that the host range of C. toxicus is determined by the availability of a suitable nematode vector. This experimental association of an Anguina and a Clavibacter suggests that there is potential for a non-toxigenic Clavibacter sp. being used for control of Anguina funesta and C. toxicus in Annual Ryegrass Toxicity.
