The Root-knot nematodes Meloidogyne incognita and Meloidogyne javanica occur on banana and plantain roots wherever this crop is grown. Meloidogyne arenaria and occasionally some other Meloidogyne spaces may also be found associated with banana and plantain.

Plant nematodes, commonly called eelworms, are worm-like animals that are too small to be seen with the maked eye. A few exceptions, e.g. adult female root-knot nematodes, are swollen and rounded. Individual plant parasitic nematodes feed on the sap from the roots of a host plant and, where there are high numbers of these nematodes, damage to the host's root system may be severe. Populations as high as 500 nematodes/g of banana roots have been recorded. The damage caused by nematodes depends on many factors including soil type, age of plant, water supply, fertiliser, rainfall, mulching and nematode species present. In general, however, they probably cause at least 25%, and sometimes up to 90%, loss in production.

Most plant feeding nematodes occur in soil and infect roots. For a crop like banana, it is not known where in the root system these nematodes feed and cause damage and if banana genotypic differences in root development affect nematode infection and damage. By suppressing root growth and activity, nematodes may affect the nutritional status of the plants, while soil nutritional status would also affect nematode infection and damage. So, manipulation of soil nutrients may be a tool for managing nematodes in bananas. This monograph shows that nematodes are randomly distributed along banana roots while nematode damage is higher close to the corm, independent of cultivar and production area. It is also shown that banana root number and root size is a critical factor in plant tolerance to nematodes. This implies that when assessing bred genotypes for nematode resistance, any section of a primary root can be used for nematode reproduction. And, promoting vigorous root growth and/or the eliminating factors that reduce root growth and development is key to avoiding a rapid yield decline of bananas due to nematode infection.
