Abstract: 

Control of citrus green mold caused by Penicillium digitatum, was evaluated on artificially inoculated oranges and tangerines immersed in 3 and 4% sodium bicarbonate (SB) (wt/vol) and potassium bicarbonate (PB) (wt/vol), with or without 200 ppm sodium hypoclorite for 60 or 180s; in 3 and 4% sodium carbonate (SC) (wt/vol) and potassium carbonate (PC) (wt/vol) at 25, 37, 45 or 53oC for 60, 180 or 300s; and kept in hot air (37oC) for 24, 48 or 72h. Hot air and water experiments were done in two sets of before and after treatment inoculations. After 3 weeks of storage at 10oC and 80% RH, the incidence of decayed fruits was determined. Results revealed that SB 4 and 3% for 180s reduced decay in Tompson Navel by 67, 65.11% and Shahsavar oranges by 80.16 and 76.04% respectively. SB4% and SB3%+NaClO 200ppm for 60s reduced decay in tagerines by 59.84 and 58.43% respectively. Control treatments caused 100%, 97-98%, and 89-90.5% decay respectively. In before treatment inoculations, PC and SC 4% at 53°C for 180s, PC3% at 45°C for 300s, PC and SC 3 and 4% at 53°C for 300s reduced decay in Tompson Navel by 100%.
SC3% at 53°C for 60 and 180s, PC3% at 45°C for 180s, PC4% and SC 3 and 4% at 53°C for 300s reduced decay in Shahsavar oranges by 100%. PC and SC 4% at 53°c for 180s, PC 4 and 3% and SC4% at 53°c for 300s and PC3% at 37°C for 180s reduced decay in tangerines by 85, 82.5, 80, 77.5, 75, and 75% respectively. Control treatments caused 92%, 100%, and 80% decay respectively.
In before treatment inoculations, Hot air for 72, 48 and 24h in Tompson Navel; for 72, 24 and 48h in Shahsavar oranges; and for 48, 72 and 24h in tangerines reduced decay by 95, 95 and 92%; 100, 85.14 and 66.22%; and 100, 95 and 33% respectively. Control treatments caused 100%, 74%, and 100% decay respectively. However, some damages observed on fruits treated with hot air for 72h.
