Abstract

Pathogens causing cymbidium yellow spot produced conidia on rape seed oilcake used as fertilizer. These conidia, as well as those produced on lesions of leaves, were the inoculation source. When plants with lesions were sprinkled with water, the pathogens increased a hundredfold on rape seed oilcake. Both types of conidia were dispersed in the wind by mist from a wind tunnel. Greenhouse experiments revealed that watering from the top of the plants also promoted fungal dispersal.
