ABSTRACT
A survey was conducted to estimate the ratio of plant parasitic nematodes associated with Walnut (Juglans regia L.) in different areas of Hazara Division, KP, Pakistan. Soil samples collected from walnut trees showed that Abbottabad and Mansehra had both parasitic and saprophytic nematodes whereas Kohistan had only saprophytic nematodes. Helicotylenchus sp. was found in abundance from Abbottabad and Mansehra alongwith other parasitic nematodes including Aphelenchus avenae, Tylenchus species, Pratylenchus species, Psilenchus species, Meloidogyne species and Trichodorus species. Carbofuran (inorganic) and poultry manure (organic) in recommended amounts were used for management and results showed that both were effective against phytonematodes. Value of P for the effect of Carbofuran in Mansehra and Abbottabad was 0.0001 and 0.0001 whereas for poultry manure it was 0.0001 and 0.0009 respectively.
