Experiments for growth inhibition of two different plant pathogenic fungal species, Alternaria alternata (KCTC26781) and Fusarium graminearum ZO3639 (type culture) and ASR1R1 (isolate from rice), by a chitinase (Chi2) expressed in the autolysing tissue of Coprinellus congregatus were carried out. In liquid media, Chi2 ($50{\mu}g/ml$) inhibited more than 90% of germination of A. alternata spore, and the growth of each fungal strain was totally inhibited by the addition of Chi2 at the concentrations of $70{\mu}g/ml$. When $6{\mu}g$ of Chi2 was added twice a day at the hyphal tip zone, both strains of F. graminearum showed growth inhibition as well as decreased hyphal branching.
