Скачать или смотреть Penicillium bilaiae Antagonistic Activity Against Alternaria alternata｜Alternaria Leaf Spot Control

In this video, we evaluate the antagonistic activity of Penicillium bilaiae against Alternaria alternata, the pathogen responsible for Alternaria leaf spot, fruit rot, and other major crop diseases.

At the Novobac laboratory, strains BV14 and BV20 were tested using a PDA dual-culture assay to observe their inhibition performance and potential for Alternaria leaf spot control.

BV14 inhibition rate: 33.96%
BV20 inhibition rate: 39.05% (strongest antagonistic activity)
Both P. bilaiae strains significantly restricted the mycelial growth of A. alternata compared with the control (CK)

These results demonstrate that Penicillium bilaiae is a promising biocontrol agent for managing Alternaria alternata infections and may offer a sustainable alternative to chemical fungicides for leaf spot management.
