Evaluation of the Nematicidal and Antifungal Activity of Aqueous Extracts of Moringa oleifera Leaves and Seed in Cucumber Field

Abstract

This aim of the two-year study was to evaluate the nematicidal and antifungal activity of Moringa oleifera extracts against Meloidogyne incognita and fungi infestation in cucumber field. The aqueous extracts of leaves and seeds of M. oleifera were used to treat the plants. The findings of the present study revealed that the plant extracts were active against the test pathogens. All treated plants were significantly higher than the control with respect to number of leaves and branches, vine length, fruit weight, and yield. Of the two varieties of cucumber used, combination of cucumber market with moringa aqueous leaf extracts gave higher results. The phytochemical screening revealed the presence of alkaloids, flavonoids, glycosides, saponins, and tannins. These possess nematicidal and antifungal activities. Combination of variety 2, Market More with Moringa leaves aqueous extract is being recommended to farmers for management of nematode and fungal diseases. Organic amendments have the advantage of controlling environmental effluence.
