Plant parasitic nematodes associated with rhizosphere soils of potato in munshigonj and bogra districts

Abstract

Abstract : A survey was conducted to identify plant parasitic nematodes and their prevalence associated with rhizosphere soils of potato (Solatium tuberosum) in Munshigonj and Bogra districts of Bangladesh during 2014-2015 and 2015-2016 cropping seasons. A total of 17 nematode species under 12 genera were recorded from rhizosphere soils of potato collected from two districts. The identified nematodes in the order of prevalence were Meloidogyne incognita, Tylenchorhynchus claytoni, Pratylenchus pratensis, Aphelenchoides sp., Cephalenchus emerginatus, Helicotylenchus dihystera, Hoplolaimus indicus, Tylenchus davainei, Tylenchorhynchus cylindricus, Tylenchorhynchus annulatus, Tylenchorhynchus sacchari, Pratylenchus penetrans, Pratylenchus coffea, Ditylenchus dipsaci, Hirschmaniella sp., Aphelenchus avenae, and Criconemoides sp. having their prevalence of collected soil samples by 35.5, 18.03, 9.59, 9.42, 5.50, 4.22, 3.55, 3.07, 2.90, 2.45, 1.25, 2.19, 2.05, 1.32, 1.21, 1.19 and 1.00%, respectively. The findings indicate that at least 17 species of plant parasitic nematodes are associated with rhizosphere soils of potato in two important potato growing districts of Bangladesh.
