This paper explored the influence of ultrasonic dip treatment method on bamboo fungi through comparing ultrasonic dip treatment with mold inhibitor dip treatment. Results showed that the appearance time sequencing in order was mold inhibitor dip treatment groups, ultrasonic dip treatment groups and control group. The control group had the highest mold rating. The mold ratings of ultrasonic groups were higher than the lower concentration mold inhibitor dip treatment groups and lower than the higher concentration mold inhibitor dip treatment groups.
