Antifungal activity, Aqueous extract, Seed-borne fungi, Poisoned food techniqueAbstract
Synthetic chemicals are extensively used to control plant diseases caused by fungi. Interest in botanicals with antifungal activity increased because of drawbacks associated with the use of synthetic chemicals. The present study was conducted to determine antifungal potential against three seed-borne fungi (Curvularia sp., Alternaria sp. and Fusarium sp.) of aqueous extract from 20 plants belonging to 14 families by poisoned food technique. The inhibition of Curvularia sp., Alternaria sp. and Fusarium sp. by extracts varied between 12.24 to 53.06%, 11.11 to 51.85% and 25.00 to 58.33% respectively. Among fungi, Fusarium sp. was inhibited to higher extent by majority of extracts. Highest inhibitory activity against Curvularia sp. was displayed by Harpullia arborea. Extract of Solanum virginianum exhibited stronger inhibitory activity against Alternaria sp. while extract of H. arborea and Azima tetracantha inhibited Fusarium sp. to higher extent. These botanical extracts can be exploited in the control of seed-borne fungi and other phytopathogenic fungi.
