Nematode pests of small millets – A review

Plant parasitic nematodes are one of the limiting factors in crop production throughout the world. Heterodera delvi, H. avanae, H. gambiensis, H. zeae, Rotylenchulus reniformis, Meloidogyne incognita, M. javanica, M. arenatia, M. graminicola, M. acronea, Aphelenchoides besseyii, Helicotylenchus abunnamai, H. dihystera Tylenchorhynchus vulgaris, T. mashhoodi, Pretylenchus penetrance, P. brachyurus, P. zeae, P. indicus Macroposthonia ornate, Criconemoides ornatus, Criconemella ornate, Hoplolaimus indicus, Caloosia exilis, Hemicriconemoides cocophilus, Hirschmanniella oryzae, Hemicycliophora sp. and Trichodorus sp. have been reported to be associated with small millet crops, but information is very meager on the occurrence, distribution, biology, interrelationship with other plant pathogens and management aspects. The present paper reviews the work carried out on nematode pests of small millet crops.
