Conidial formation of Discula theae-sinensis on fallen diseased tea leaves

Key Points

• This research aims to understand the role of diseased tea leaves in the conidial formation of Discula theae-sinensis and its potential as a source of infection.
• Investigated conidial formation on fallen diseased tea leaves over time
• Conducted experiments starting in June and October, monitoring formation through April of the following year
• Set up the experiments on the surface of tea fields
• Conidial formation was below detection limits four weeks after the June trial began.
• Formation was observed in the October trial, continuing into the following April.
• Concludes that diseased leaves can act as a winter infection source for tea anthracnose disease.
