Step closer to understanding mango disorder

Published

Scientists in the Northern Territory have made an exciting breakthrough in understanding the cause of resin canal discolouration (RCD) in mangoes.

New research has determined the cause of the disorder, which causes blemishes and discoloration on the fruit, to be a bacterial infection rather than a problem with the plant.

Mangoes infected with RCD are safe to eat, but the blemishes and discolouration makes the fruit less appealing to consumers.

The exciting research was undertaken by ARC Training Centre for Innovative Horticultural Products PhD candidate Umar Muhammad and Department of Primary Industry and Resources (DPIR) scientists.

The number of cases of RCD has been increasing in recent years, particularly in the Northern Territory, which is why researchers have focused on this disease.

While it is still not clear where in the production system infection normally occurs, this research suggests it occurs post-harvest and that avoiding contamination is essential to prevent RCD

The research was funded by the Australian Research Council Industrial Transformation Research Program, Woolworths and the University of Tasmania with in-kind support from the Northern Territory Government and the Tasmanian Institute of Agriculture.
