| Abstract: | The antagonistic mechanisms of ethyl acetate crude extract of BEB99 strains for Fusarium oxysporium were studied by biological chemical method. The results revealed that ethyl acetate crude extract could influence lipid peroxidation, ergosterol content, protein content, the activity of PMG of Fusarium oxysporum. But it could not decompose the chitin. |
