Postharvest disease of Lingwu Changzao (Ziziphus jujuba Mill.) Fruit and the effect of biocontrol agent on fruit decay

 

A mycological survey was carried out on the Lingwu Changzao fruits in storage and the efficacy of bioantifungal agent against the decay in vivo was evaluated at room temperature. Five microfungi were isolated by tissue separation technique, artificial inoculations with the fungi were also performed in fruits as typical storage decay. The results on bio-efficacy indicated that oligochitosan concentrations ≥0.75 mg/ml significantly decreased black mould and gray mould disease caused by A. alternata and B. cinerea in jujube fruit stored at 25°C, combining Natamycin with oligochitosan (KD-2) resulted in more effective control of disease, only 19.96% of the fruits showed decay while in the control decay incidence was 60.12%.
