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.
