HANDLING SYSTEMS TO REDUCE MANGO SAPBURN
Recent work by officers of the Queensland Department of Primary Industries (QDPI) has demonstrated that these levels can be reduced by a number of methods: (a) using detergent dips and sprays prior to destemming; (b) destemming under a lime solution; (c) packing with short stems; (d) picking without stems onto a harvesting aid and dipping or spraying detergent onto the fruit immediately. All methods resulted in a reduction in both the severity and the percentage of fruit with sapburn. This was noticed during in farm trials and market assessments during the 1991/92 mango season. The harvesting aid proved most effective, reducing total sapburn to 15.9 %. The harvesting aid also offers considerable savings in labour costs by reducing the number of pickers by nearly half.
