Cinnamon, a major forestry plant with significant economic and medicinal value, has contributed substantially to
the production value for people in Lang Son province, particulary in Trang Dinh district. Cinnamon seedlings in
many nurseries in Lang Son are being attacked by leaf blight diseases, which can cause the seedlings to die or
reduce the quality of the cinnamon seedlings before being planted in the plantations. This study aims to identify
the main leaf blight causing - disease and prevention measures at the laboratory and nursery scale to manage
cinnamon leaf causing - disease at the nursery stage in Lang Son province. The results determined that
the pathogen causing the leaf blight disease is Diaporthe eucalyptorum. The effectiveness of prevention
measures is different. The biological fungicide with the highest ability to prevent pathogen that caused leaf blight
disease is Trichoderma, with an effective prevention of 76.13%. Chemicals with the highest ability to prevent
pathogen that caused leaf blight disease include the active ingredients of Propiconazole + Difenoconazole with
80.47% effectiveness. These are highly effective preventive agents capable of reducing the desease incidence
and damage severity of pathogen causing cinnamon seedlings leaves in the nursery.
