Abstract
The study aimed at controlling the mycelial growth and germination of Mycosphaerella fijiensis in Petri dish by using three plant defense stimulators. Approximately, 2 mL of each stimulator (Vacciplant®, Callel® and calliete®) were added to the different M. fijiensis culture media. The results obtained show that Vacciplant® and Callel® promote the in vitro growth of M. fijiensis contrary to calliete® which inhibits it. Indeed, it causes total mortality (100%) of conidia at the sporulation stage.
