Nematode parasites of spices, condiments and medicinal plants.

Abstract

This chapter presents the species of plant parasitic nematodes infesting Piper nigrum (mainly Radopholus similis and Meloidogyne spp.), cardamom (mainly Meloidogyne spp.), ginger (mainly Meloidogyne spp. and Pratylenchus coffeae), turmeric (mainly Meloidogyne sp., Radopholus similis and P. coffeae), other spice plants, Piper betle (Meloidogyne incognita, Radopholus similis and Rotylenchulus reniformis), Piper methysticum, Hyoscyamus muticus, H. niger, H. albus, Withania somnifera, Bacopa monnieri, Chlorophytum borivilianum and Mentha sp. are presented. Information on symptoms of infestation; biology, life cycle and host range of the nematode; disease complexes; extent of damage on crops; and control measures (cultural, chemical and biological control, and resistance in crops) is included. Tabulated data on plant parasitic nematodes associated with Piper nigrum, cardamom, ginger, turmeric, fennel, fenugreek, coriander [Coriandrum sativum], cumin [Cuminum cyminum], celery, dill and vanilla are also presented.
