Nevertheless, none of the treatments applied alone were as effective as the integrated
use of PDIC, inorganic salt and hot water treatments. Preharvest
treatment with either salicylic acid or potassium phosphonate at
1000 mg L−1 combined with postharvest dip in 3% aqueous sodium
bicarbonate at 51.5 C yielded the lowest disease severity rating of
1.81 (equivalent to less than 5% fruit area affected or slight infection)
(Table 2).
