Samsun ili Bafra ilçesin'de beyaz baş lahana alanlarında siyah damar çürüklük etmeni xanthomonas campestris PV.Campestris (Pammel 1895) Dowson 1939' nin belirlenmesi

Bafra Ovası’nda 2003-2004 yılları arasında beyaz baş lahana yetiştirilen alanlarda siyah damar çürüklük etmeni olan Xanthomonas campestrıs pv. campestris’in belirlenmesine yönelik bir survey çalışması yapılmıştır. Survey sonunda 10 adet izolat, X. campestris pv. campestris olarak teşhis edilmiştir. İzolatların tanısı için patojenite testi, tütünde aşırı duyarlılık testi ve biyokimyasal testler yapılmıştır. Hastalık şiddeti olarak en yüksek oran % 41.6 ile Kuşçular Köyü’nde tespit edilmiştir.

Occurrence of black rot caused by xanthomonas campestris pv. campestris (Pammel 1895) Dowson 1939) in white head cabbage (Brasicca oleracea var. capitata)growing areas in Bafra districts of Samsun province

Survey to determine the causal agent of black rot (Xanthomonas campestrıs pv. campestris) in white head cabbage (Brasicca oleracea var. capitata) growing areas in Bafra Plain was conducted during the years of 2003-2004. In the survey, ten isolates were identified as X. campestris pv. campestris. Pathogenicity, tobacco hypersensitivity and biochemical tests were used for the diagnosis of the identified isolates. The highest disease severity rate (41.6%) was determined at Kuscular Village.
