The area planted to soybean in South Africa has increased by 54% since the 2009 growing season, mainly
as a result of the increasing demand for protein-rich food and fodder sources. Moreover, the introduction
of advanced technology, namely the availability of genetically modified herbicide tolerant soybean cultivars
also contributed towards increased soybean production. The omnipresence of plant-parasitic nematodes in
local agricultural soils, however, poses a threat to the sustainable expansion and production of soybean and
other rotation crops. Meloidogyne incognita and M. javanica are the predominant nematode pests in local
soybean production areas and those where other grain-, legume- and/or vegetable crops are grown. The
lack of registered nematicides for soybean locally, crop production systems that are conducive to nematode
pest build-ups as well as the limited availability of genetic host plant resistance to root-knot nematode pests,
complicate their management. Research aimed at various aspects related to soybean-nematode research,
namely, audits of nematode assemblages associated with the crop, identification of genetic host plant
resistance in soybean germplasm to M. incognita and M. javanica, the use of molecular markers that are
linked to such genetic resistance traits as well as agronomic performance of pre-released cultivars that
can be valuable to producers and the industry are accentuated in this review. Evaluation of syntheticallyderived
as well as biological-control agents are also discussed as complementary management tactics. It
is important that lessons learned through extensive research on soybean-nematode interactions in South
Africa be shared with researchers and industries in other countries as they might experience or expect similar
problems and/or challenges
