Diseased Anoectochihus roxburghii showing rotten leaf, rotten and lodging stem were collected from Heyuan,
Guangdong and the pathogen was isolated. By pathogenicity test, pathogen morphology and molecular biology methods, it
was confirmed that the disease was gray mould caused by Botrytis. Under the condition of low temperature and high
humidity environment, the diseases was easy to occur, and spread rapidly. The study provided a theoretical basis for
formulating the corresponding prevention and control strategy. |
