Abstract:
    This study was carried out to test the potency of both aqueous and ethanolic extracts of small and large <i>Aframomum melegueta</i> (alligator pepper) on the control of postharvest deterioration of lime (<i>Citrus aurantifolia</i>) and lemon (<i>Citrus limonum</i>) caused mostly by <i>Aspergillus niger, Trichothecium roseum, Rhizoctonia species, Alternaria tenuis, Absidia ramose</i> and<i> Rhizopus stolonifer</i> which were isolated from the fruits of lime and lemon. The fungal isolated were tested for its ability to cause the same disease condition in a healthy Citrus (<i>C. limonum</i> and <i>C. aurantifolia).</i>The extracts were concentrated at different range from 5-30 mg/ml. The study showed that the extracts of <i>Aframomum melegueta</i> were able to suppress fungi growth on <i>Citrus aurantifolia</i> and <i>Citrus limonum</i>. All the concentrations of the ethanolic extract of small <i>A. melegueta</i> were potent to all the organisms. The small seed ethanolic extracts were most effective on <i>Rhizopus stolonifer</i> while larege seed ethanolic extracts were most effective on <i>Alternaria tenuis</i> which recorded the highest zone of inhibition. I recommended that 5mg/ml concentration which has the highest zone of inhibition of the extract can be used as spray in controlling the postharvest deterioration of the citrus fruits. Therefore, they will serve as a good natural seed fungicide (protectant) against Citrus in storage.
