Effect of Castor Bean [Ricinus communis L. (Euphorbiaceae)] and Dieffenbachia [Dieffenbachia maculata (Araceae)] of Root-knot Nematode (Meloidogyne incognita) on Greenhouse Tomatoes
Abstract :One of
the major pests of the vegetables is root-knot nematodes (Meloidogyne spp.) (RKNs) which cause economic losses in production
by causing knots in the roots. RKNs are generally seen in the greenhouse
vegetable growing areas of the coastal regions of Turkey. In this study, the
efficacy of pieces of leaves of castor bean [Ricinus communis L. (Euphorbiaceae)] and dieffenbachia [Dieffenbachia
maculata Schott (Araceae)] were evaluated at two different applications (10
and 15 g) against Meloidogyne incognita on
tomatoes. Experiments were carried out in pots under
greenhouse conditions using tomatoes cv. Seyran F1 as assay plants that are
commonly cultivated in Turkey. The efficacy of pieces of leaves of R. communis and D. maculata were
evaluated at two different applications (10 and 15 g pieces of leaves pot-1)
against M. incognita on tomatoes. As a result of this
experiment, R. communis and D. maculata were found to be effective against M. incognita. Of these plants especially R. communis demonstrated to have a quite high effect
