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
