To reduce the impact associated with Ganoderma root rot disease in A. mangium plantations.

Isolates of the fungi Phlebiopsis and Cerrena have been shown to have significant potential as biological control agents (BCAs) against Ganoderma and also to produce oidia. It has been established that stumps can be inoculated with BCA oidia in the field and it is this methodological approach that will be pursued. Activities planned are:

1.1. BCA and pathogen spore co-inoculation onto stumps.

1.2. Methods for producing, formulating and field application of the biocontrol agent will be refined and systems for production.

1.3. The most promising BCAs will be applied to acacia and eucalypt stumps in large scale field trials.
