Integrated nematode management: state-of-the-art and visions for the future
Abstract Yam, Dioscorea spp., one of the oldest food crops known to humans, is the fourth most important root and tuber crop globally. It is a tropical plant that provides food and income for the people in the regions where it is grown. Major nematode pests reported on yams include Scutellonema bradys, Meloidogyne spp., Pratylenchus spp. and Rotylenchulus reniformis. This chapter addresses S. bradys, causing dry rot disease of yams in field and storage. When S. bradys infected seed tubers are planted, plant survival is reduced, and the speed of the disease cycle is amplified leading to reduced yield. The economic importance, host range, distribution, damage symptoms, biology and life cycle, interactions with other nematodes and pathogens, recommended integrated nematode management, and management optimization of S. bradys are discussed. Future research requirements and developments are also mentioned.
