Abstract

Pomegranate (Punica granatum L.) is one of the most important fruit species grown in Turkey. Fungal pathogens cause significant losses in quality and yield of pomegranate fruit in orchards and warehouses. Pomegranate fruit and crown rot, caused by Coniella granati, is one of the most serious diseases of pomegranate. No fungicides have been registered in Turkey to control this disease. In this study, the antifungal effect of etidote-67, borax, boric acid, sodium benzoate, sodium nitrite, sodium carbonate and potassium sorbate on mycelial growth of C. granati was investigated in vitro. The antifungal effect of the salts on mycelial growth of the fungus was determined at concentrations of 0.01, 0.02, 0.03, 0.04, 0.05, 0.06 and 0.07 (w/v). Increased concentrations of etidote-67, borax, boric acid, sodium benzoate, sodium nitrite, sodium carbonate, and potassium sorbate significantly inhibited mycelial growth of the fungus compared to the control. Significant differences were found between the efficacy of the treatments (P<0.05). The concentrations of 0.04% and 0.03% of etidot-67 and borax salts, respectively, were determined to be the doses that completely inhibited mycelial growth of the fungus. Boric acid, sodium nitrite, sodium carbonate and potassium sorbate completely inhibited the fungal mycelial growth at a concentration of 0.05%, while sodium benzoate inhibited fungal mycelial growth at a relatively high concentration (0.07%). When comparing the effective concentrations (EC50) of the salts inhibiting mycelial growth by 50%, sodium benzoate showed a stronger inhibitory effect against the fungus. In conclusion, the results of this study show that boron, sodium, and potassium salts can be used as an alternative to synthetic fungicides to control fruit and crown rot disease caused by C. granati in pomegranate.
