Abstract

Abstract:

The suppressive and control effect of Chinese leek on the growth of Fusarium oxysporum f.sp. Cubense race 4(Foc4) and banana Fusarium wilt was studies in laboratory and greenhouse. The results showed the extracts of Chinese leek significantly suppressed the growth of Foc4 and resulted in highly lethal effects on the spores. Moreover, in the peat soil artificially inoculated with Foc4 and in the field soil naturally infected with Foc, the disease incidence and disease severity index greatly reduced in the treatment of water extracts and leek residues, which suggested Chinese leek had high control effect on banana Fusarium wilt．

Key words: banana, Fusarium oxysporum F.Sp. Cubense, Chinese leek, biological control
