Determination of Root Lesion Nematodes (Pratylenchus spp.) on Dry Bean Growing Areas in Central Kızılırmak Valley

Abstract

Dry bean contains high fiber, minerals, and vitamins as well as protein. Although it has an important place for human nutrition, dry bean production is gradually decreasing. Biotic and abiotic factors affect dry beans productions. One of the important biotic effects is plant-parasitic nematodes. Each year, plant-parasitic nematodes have been estimated caused damage of 80 billion dollars. Root lesion nematodes are important
root parasitic nematodes especially cereal and legumes growing areas. The aim of this study was to determine root lesion nematodes in Central Kızılırmak Valley which is one of the important dry bean growing areas in Turkey. In this study, 144 soil and root samples were collected from dry bean fields of 8 cities. Soil and root samples were extracted by modified baermann funnel method (pedri dish method). The survey result showed that Pratylenchus species is widespread in all areas. Most common species was found in Pratylenchus thornei (Sher et Allen).
