Plant Extracts Effect of Seed born fungi vigna radiata

Abstract The present study was conducted to isolate and identify seed-borne mycoflora from six varieties of Vigna radiata—BM-4, BPMR-14, JL-781, BPMR-187, Kopargaon, and a local variety. The most frequently isolated fungi included Aspergillus flavus, Aspergillus niger, Alternaria alternata, Curvularia lunata, Cladosporium oxysporum, Fusarium roseum, Macrophomina phaseolina, and Trichoderma viride. These fungi were identified based on colony morphology and microscopic characteristics. To explore eco-friendly approaches for controlling these seed-borne pathogens, selected plant extracts were used in vitro. Leaf, rhizome, and seed extracts of botanicals such as Azadirachta indica (Neem), Curcuma longa (Turmeric), Allium sativum (Garlic), Zingiber officinale (Ginger), and Aegle marmelos (Bael) were evaluated for their antifungal efficacy using the poisoned food technique. The results showed significant inhibition of fungal growth by several extracts, with Allium sativum and Azadirachta indica showing the most promising effects. This study highlights the potential of botanical extracts as natural, sustainable alternatives to chemical fungicides in managing seed-borne fungal pathogens of Vigna radiata.
