DAMAGE BY MELOIDOGYNE JAVANICA ON VINES IN SOUTH AFRICA

Abstract

A declining vineyard in the district of Worcester, South Africa, was found heavily infested by Meloidogyne javanica. Roots were distorted and swollen, forming small galls. The feeding sites of the nematodes comprised the typical giant cells with granular cytoplasm and numerous hypertrophied nuclei. Vascular tissue within the galls was disorganized. From each gall protruded one or more females of the nematode with 200 to 450 eggs in each gelatinous matrix.
