Meloidogyne species infesting tomatoes, cucumbers and eggplants grown in Kahramanmaraş Province, Turkey

Abstract

In 2009 and 2010, 107 samples of roots and associated soil were collected from vegetable-growing fields in Andirin, Narli, Pazarcik and Türkoǧlu of Kahramanmaraş Province, Turkey. Populations of root-knot nematode were found in tomatoes, eggplants and cucumbers and the species identified using isozymes analysis, mainly esterase resolved by PAGE (Polyacrylamide Gel Electrophoresis) and perineal patterns of nematode females. A single species of root-knot nematode, Meloidogyne incognita was identified from the samples collected. Two esterase phenotypes, one with a single band (I1) and the other with double bands (I2) were found at proportions of 8.5 and 15.8% of total samples, respectively. About 24% of the fields were found to be infested.
