Abstract:
The results revealed all of the test biocontrol agents as potential antagonists, which significantly inhibited mycelial growth of P. zingiberi, over untreated control. However Trichoderma hamatum resulted with significantly highest mycelial inhibition (87.77%), followed by T. koningii and Metarhizium anisopliae (76.66%), Verticillium lecanii (71.48%), T. asperellum (65.55%), T. harzianum (55.18%), Aspergillus niger (46.66%) and Pseudomonas fluorescens (44.44%) All nine test phytoextracts (each @10 and 20%) were found fungistatic to P. zingiberi and significantly inhibited mycelial growth of the test pathogen, over untreated control. Among phytoextracts Lawsonia inermis resulted with significantly highest mycelial growth inhibition (52.59 and 66.66%), followed by Allium sativum L. (32.59 and 36.66%), Azadirachta indica (24.81 and 28.14%), Zingiber officinale (23.70 and 32.22%) and Allium cepa (22.59 and 26.66%), respectively @ 10 and 20%.
