OCCURRENCE OF BACTERIAL AND FUNGAL PARASITES ON CYST NEMATODE (HETERODERA CRUCIFERAE FRANKLIN) IN CABBAGE GROWING AREAS OF SAMSUN, TURKEY

摘要

During a survey, cysts of Heterodera cruciferae Franklin in cabbage (Brassica olareacae L.) growing areas in Black Sea Region of Turkey were found infected with 2 fungi and 1 bacterium. The natural infestation rate of F. oxysporum on mature cysts was35% and the rate of infected eggs by F. oxysporum and Thallospora sp. in a cyst were 55% and 46%, respectively. Natural infestation rate of Fluorescent Pseudomonas sp. strain No. 2 and No, 6 was 23% and 35%; infected eggs rate was 29% and 42%, respectively. This is a first record on the occurrence of the Fluorescent Pseudomonas, Thallospora sp, and F. oxysporum on Heterodera cruciferae from Turkey.
