Alternative nematode management strategies
Mashela, Phatu W.; De Waele, Dirk; Fourie, Hendrika; Dube, Zakheleni; Khosa, Mbokota C. (Springer, 2017)In South Africa, about 48 % of the people live in rural areas.

Cabasan, Ma Teodora Nadong; De Waele, Dirk; Kumar, Arvind (Taylor & Francis, 2017)The rice root-knot nematode (RKN), Meloidogyne graminicola, is an important pathogen affecting rice production in South and Southeast Asia. Efficacy of resistance and tolerance in selected M. graminicola-resistant African ... -
Evaluation of resistance and tolerance of rice genotypes from crosses of Oryza glaberrima and O. sativa to the rice root-knot nematode, Meloidogyne graminicola

Histopathology of the rice root-knot nematode, Meloidogyne graminicola, on Oryza sativa and O. glaberrima
Cabasan, Ma Teodora Nadong; Kumar, Arvind; Bellafiore, Stéphane; De Waele, Dirk (Brill Academic Publishers, 2014)The root-knot nematode, Meloidogyne graminicola, can cause substantial rice yield losses. Understanding the mechanisms of resistance to this nematode species in known resistant rice genotypes may help to improve rice ... -
Host status of rotation crops in Asian rice-based cropping systems to the rice root-knot nematode Meloidogyne graminicola
Win, Pa Pa; De Waele, Dirk; Kyi, Pyone Pyone; Maung, Zin Thu Zar; Myint, Yi Yi; Cabasan, Ma Teodora Nadong (Springer, 2016)Rotation with nonhost crops is an important practice used for root-knot nematode (RKN) management. Screenhouse experiments were conducted to evaluate the response infection of 27 cultivars belonging to 14 crops (blackgram, ... -
A hypersensitivity-like response to Meloidogyne graminicola in rice (Oryza sativa)
Phan, Ngan Thi; De Waele, Dirk; Lorieux, Mathias; Xiong, Lizhong; Bellafiore, Stephane (The American Phytopathological Society, 2018)Meloidogyne graminicola is a major plant-parasitic nematode affecting rice cultivation in Asia. Resistance to this nematode was found in the African rice genotypes Oryza glaberrima and O. longistaminata; however, due to ... -
Introduction (Nematology in South Africa: a view from the 21st century)
Fourie, Hendrika; De Waele, Dirk; Jones, Robin K.; Spaull, Vaughan W.; Daneel, Mieke S. (Springer, 2017)This book documents what we know about the nematodes that parasitise the crops of South Africa. It also provides information on the free-living nematodes that occur in the soil and inland waterbodies, those found on the ... -
Mapping quantitative trait loci of Meloidogyne graminicola resistance and tolerance in a recombinant inbred line population of Oryza glaberrima × O. sativa
