چکیده

A study was conducted to determine the pathogens causing root rot, wilt and dieback disease of Cinnamomum cassia (Chinese cinnamon or cassia) in Vietnam, nurseries plantations Yen Bai, Quang Ninh, Thanh Hoa Nam provinces, streams Bai province. Pathogens were identified using morphology internal transcribed spacer (ITS) sequence analysis. The 204 isolates obtained included 125 Phytophthora 79 from other oomycete genera. There 112 P. cinnamomi, four heveae, two virginiana, three multibullata × vanyenensis. pathogenicity virulence 16 vanyenensis assessed lesion size after under-bark inoculation C. stems, damage following 4-month-old seedlings. most virulent isolate both assessments a cinnamomi plantation. Isolates showed wide range virulence, with healthy trees seedlings showing lowest virulence. vanyenensis, heveae moderate low pathogenicity. This that although is common pathogen associated Vietnamese plantations, species may also cause this disease. Knowledge presence these soil- waterborne will encourage improved soil water hygiene implement measures prevent spread plantations.
