Re: dwarf ducasse - brown spots on leaf
The whole point of tissue culture is the avoidance of pests and diseases. I am not surprised that the nursery and the dpi would take such concerns extremely seriously, and so they should, otherwise an entire industry would be at risk.
Lucky that the concerns about a fungus were pure hearsay and have not been validated.
It is normal for young bananas plants to develop some spots on the leaves in cooler weather. CSIRO research noted that some leaf damage can occur at 10 degrees celsius, well above minimum temperatures at ground level in virtually every part of Australia in the cooler months.
