Epidemiology of the fungus Chondrostereum purpureum, a biological control agent of the asexual reproduction of deciduous tree species in forest environment.

摘要

The objective of this study is to assess parts of the epidemiology of the pathogenic fungus Chondrostereum purpureum used as a biocontrol agent to control vegetative reproduction of deciduous tree species. The study is composed of three parts, namely (1) the evaluation of the sporulation of the silverleaf fungus in an indoor experiment; (2) the assessment of spore dispersal of the pathogen using simulation; and (3) the evaluation of the interaction host-pathogen using selected Canadian isolates as well as selected tree species. Results indicate that sporulation reaches a maximum value when air temperature is close to 20
