The second volume of the IMPD series describes aspects related to most important phytoparasitic nematodes, considering the integration of biological control methods with other management practices and technologies, including the use of predatory nematodes and microbial rhizosphere antogonists. Chapters cover topics such as the mode of action and interactions of nematophagous fungi, the efficacy of control and management of plant parasitic nematode communities through a soil conservation approach, and exploitation of nematodes-bacteria antagonistic relationships. A focus is given on regional issues, like the management of nematodes parasitizing staple crops, i.e. Andean tubers or some important grain crops, like soybean in North and South America or cereals. A review on nematode management in cotton is integrated by a chapter on management of nematodes on wheat. New technologies are also revised, including the potentials of control methods based on RNA interference and issues related to the use of biofumigation to control nematodes in different regional or crop contexts.
