Quality defect – skin spotting on Hass
• Skin spotting = nodule damage
• Can be an entry point for disease
• Skin spotting accumulates down the
supply chain
• Skin spotting may not be visible once
avocados start to colour (at retail)

Grower feedback
• Identified several factors that can affect quality
– Heavily pruned blocks = poorer fruit quality
– Light yields = poorer fruit quality
– High vegetative vigour = poorer fruit quality

Growers opinions on how they could use the data
1. Decision making regarding a late fungicide
application
2. Timing of harvest to optimize quality (relating to
optimum fruit maturity)
3. Help with marketing decisions
4. Useful to rank their quality against other growers &
identify blocks that need improving

Conclusions
Problems are compounded throughout the chain
and co-operation of all members is needed
to solve them
Monitoring tools are available for managing fruit quality
Information and training is required to improve
chain performance
