Plant Parasitic nematodes associated with Maple (Acer caesium) and Poplar (populous nigra) in district Swabi

Abstract

Background: Parasitic nematodes are very destructive to crops, ornamental plants and woody plants as well which cause most severe diseases in plants and feed on the roots of these plants. Objective: Main aim of this study to identify different species of nematodes associated with Maple (Acer caesium) and Poplar (populous nigra) trees at district Swabi, Khyber Pakhtunkhwa, Pakistan. Methodology: Some Maple and Poplar growing areas of District Swabi were surveyed during the year 2019, for the occurrence and incidence of parasitic nematode. Soil samples collected from different localities were analyzed for the nematode. Plant-parasitic nematodes were extracted from soil by Cobb methods, and identified species after fixation. Result: A total of 7 species were found the results showed maximum soil samples were infected with the nematodes. Maximum infection was recorded in Zaida, Manki and Anbar. Following nematodes were found named Paratylenchus Larvae, Aphelenchus avenae, helicotylenchus dihystera, Tylenchus, Trichodorous and Meloidogyne incognita. Ratio of occurrence among all different varieties of nematodes Meloidogyne incognita species show most abundance in two localities Lahor and Zaida. Conclusion: The indication of result clears this fact that studied area mostly infected with different types of parasitic nematodes species which highly affect the Maple (Acer caesium) and Poplar (populous nigra) plants.
