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 is 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 nematodes. Soil samples collected from different localities were analyzed for the nematodes. Plant-parasitic nematodes were extracted from soil by Cobb methods, and identified the species after fixation.
 Result: Maximum analyzed simples were infected and among all localities seven different species of nematodes has been recorded. 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 shows most abundance in two localities Lahor and Zaida.
 Conclusion: The results clearly indicate the fact that studied area is mostly infected with different types of parasitic nematodes species which highly affect the Maple (Acer caesium) and Poplar (populous nigra) plants.
