Study on the antifungal effect of mint extracts on postharvest life of navel orange and comparison its effect with Karbandazim fungicide
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 12
Abstract
In order to investigate the antifungal effect of medicinal plant extract on postharvest life of navel orange and comparison its effect with chemical treatment, this experiment was conducted in Complete Randomized Design (CRD) with 7 treatments and 4 replications. Treatments consists: control (inoculated with penicillium fungi without any treatments), dipping in solution Karbandazim at three concentrations range (1000, 1500, 2000 mg.lit-1) for 5 min and medicinal plant extract Mint 150, 300 and 450 mg.lit-1. Treated fruits were stored under ambient storage for 3 month. At the end of experiment decay amount, TSS juice, total acid (TA), pH, vitamin C, TSS/TA ratio, weight loss was measured. Results showed that quality and quantity of navel orange changed during storage, but this change was different depending on treatment type. Data showed that minimum percentage of weight loss and decay, high value of, TSS/TA ratio was in mint treatment(450 mg.lit-1).As level of Mint extract were increased the percentage of weight loss and decay, were decreased and TSS amount was increased. The maximum of TSS amount was recorded in Mint extract (150 mg.lit-1). karbandazim 1500 mg.lit-1 and mint extract 300 mg.lit-1 has no significant differences in control of decay percent.
