Promising antifungal effects of Citrus maxima peel for the control of banana fruit rot
摘要
The current work investigated the promising antifungal effects of Citrus maxima, popularly known as “pomelo” against fruit rot disease of banana caused by Fusarium verticillioides. Results showed that the 1.75 g/L concentration of C. maxima peels can be used as a protective and a curative application on banana to inhibit fruit rot disease. The Citrus Maxima Peel Extract, CMPE, significantly disrupts the normal growth patterns of F. verticillioides, with marked changes observed in its mycelia and conidia. The fungal hyphae exhibited notable distortion, and the conidia were observed to burst, indicating severe cellular damage. These observations highlight the potent inhibitory effects of CMPE on the growth and reproduction of F. verticillioides. Twenty-five chemical compounds were identified in CMPE. The major compounds found in the CMPE were 2-Monopalmitin (24.54%), Glyceryl monostearate (16.08%), Sucrose (11.38%), 2,2'-Methylenebis (6-tert-butyl-p-Cresol) (6.92%), D-glycero-d-ido-heptose (5.69%), Palmitic acid (5.57%), and 3-Deoxy-d-mannoic lactone (5.25%). CMPE attributes promising antifungal effects towards F. verticillioides and could potentially replace synthetic conventional fungicides, offering a more sustainable and effective solution for agriculture in the future.
