Screening Bacillus strains for antagonistic activity against Fusarium sp. and Phytophthora palmivora causing diseases in corn (Zea mays L.)

Tóm tắt

61 Bacillus strains originally isolated from Can Gio manglicolous soil were evaluated in vitro for possible antagonistic activity against Fusarium sp. and Phytophthora palmivora. All of screened strains possessed antagonistic properties. Isolates B44 was the most effective in inhibiting Fusarium sp. growth. Isolates B34 was the most effective in inhibiting P. palmivora growth. These two isolates were tested in vivo for controlling diseases in corn (Zea mays L.). Only B44 strains could efficiently reduce corn death rate.
