Plant parasitic nematodes associated with wheat and maize

Abstract

Nematodes associated with wheat and maize cause different diseases and reduced their yield. Survey was carried out in wheat and maize fields at the University of Karachi near Department of Environmental Studies, mooti baag, Nursery (NNRC) and Crops Diseases Research Institute (CDRI). During survey a total of 16 soil samples were collected randomly from the roots of the plants. After laboratory analysis many plant parasitic nematodes were identified in which Longidorus pisi, Tylenchorhynchus annulatus, Helicotylenchus egypteansis, Hoplolaimus indicus, Hemicriconemoides mangiferae., Pratylenchus spp,  Tylenchus spp., Hetrodera spp., Aphelenchus spp. and Rotylenchus spp. are included. A large number of free-living nematodes were also found along with plant parasitic nematodes. In the CDRI wheat samples were collected the large amount of population of free living nematodes were present. Whereas the population of plant parasitic nematodes were not sufficient. From mooti baag, Department of Environmental Studies and Nursery of NNRC sample of maize were collected in which more plant parasitic nematodes were found. © 2020 The Author(s)
