Results showed that, pyrolin had obvious action on two species of fungi, and the antifungal effect was positively correlative with concentration. The EC50 was 0.4076 mg/mL and 0.4626 mg/mL respectively after cultured 3 days. The main antifungal period was the fast growth period of fungi, and lead to it lag behind. Observation under SEM revealed that pyrolin caused a series of marked morphological and structural alterations of hyphal. These changes included mutual adhesion of mycelium, the hyphal was irregular in diameter, local denting, some of mycelium was broken, disruption of cell wall, outbreaking of inner cytoplast, and the empty cavity appeared. As a result, pyrolin restrained the growth of these fungi.
