Abstract
Root-knot nematodes (Meloidogyne species, RKN) are unsegmented round worms which are usually invisible to the naked eye, but the galls they produce in infested plant roots are often easy to spot. RKNs are plant-parasitic with a broad host range, which includes vegetables, field crops, tree and vine fruits, ornamentals, pastures and some weed species.
Root-knot nematodes reduce yields of many horticulture crops, including carrot, potato, sweet potato, tomato, capsicum, pumpkin, zucchini, avocado, grapes and lettuce. RKNs favour the sandy soils common throughout the south-west of Western Australia’s (WA’s) horticultural area.
