Online published on 27 November, 2018. Abstract The Himachal Pradesh state is endowed with various agro-climatic zones represented by different types of vegetation, it was obvious to be infected with different species of phytoparasitic nematodes depending upon their preferential hosts and climatic conditions. Investigations conducted to ascertain the status of genus Meloidogyne Goeldi, 1892 in the state of Himachal Pradesh, four species of genus Meloidogyne i.e. M. incognita, M. javanica, M.graminicola and M. arenaria were identified infecting different crops in the state. Among these, the most frequently occurring was M. incognita, recorded from most of the districts associated with vegetable, fruit and ornamental crops. The incidence of M. javanica was recorded at low altitude range of 322–478 m.a.s.l. in papaya and litchi growing in Rampur and Santoshgarh locations of district Una. The rice root-knot nematode, M. graminicola was recorded to infect cereals like, rice, wheat and maize in Kangra, Mandi and Hamirpur regions having subtropical climate (720–1010 m.a.s.l.). Another nematode that registered its occurrence for the first time in the state was M. arenaria reported from okra and tomato in Karenzi located in district Sirmaur only.
