Effect of selected botanical extracts against Curvularia Sp. and Meloidogyne incognita (J2)

Abstract

Antifungal activity of aqueous extract of leaves and flowers of Plumeria rubra, Chromolaena odorata, Rauwolfia serpentina, Ocimum tenuiflorum, Ziziphus mauritiana, Tectona grandis, Catharanthus roseus, Lantana camara, Peltophorum pterocarpum was tested in vitro and it showed antifungal activity against the plant pathogen Curvularia sp. and Meloidogyne incognita. As compared to the control, the extract of Chromolaena odorata was found to be most effective to inhibit the growth of the Curvularia sp. and also showed the highest emergence of juveniles (J2) of Meloidogyne incognita released from the egg masses. The best inhibitory effect which showed 40.6% reduction as compared to the control was Chromolaena odorata against Curvularia sp. whereas Chromolaena odorata at 99.63% also showed the highest significant reduction released from the egg masses of Meloidogyne incognita of J2. The experiment was laid out in randomized complete block design with three replications and nine treatments.
