First report of leaf blight wilt on Dracaena sanderiana by Pantoea stewartii subsp. indologenes in China.

Abstract

Dracaena sanderiana [[]Dracaena braunii] is one of the important export ornamental plants in southern China. In Zhanjiang district, D. sanderiana was seriously affected by a disease in the field in 2017 with an incidence of 35-80[%]. Both young and older leaves developed necrotic lesions with small water-soaked spots at the tip or at the margin of the leaves, which then enlarged and were bordered by chlorosis. Diseased plants were collected in Zhanjiang city, Nanning city, and Haikou city, Guangdong, China. The causal pathogen was isolated and identified as Pantoea stewartii subsp. indologenes based on morphological characteristics, molecular data (16S ribosomal DNA sequence analysis), and pathogenicity tests. This is thought to be the first report of D. sanderiana caused by P. stewartii subsp. indologenes in China.
