Cinerea were observed, and the inhibition rates could reach 100% at the concentration of 20μg/mL. The sclerotium formation, sclerotium form and distribution were influenced in different extent. C8-10 presented 90% inhibition rate on sporulation at the concentration of 40μg/mL. 1227 and C8-10 surfactants could obviously increase the permeability of cell membrane over the concentration of 20μg/mL.
