| Abstract: | 【Objective】Antibacterial effects of 17 Trichoderma spp. strains on banana Fusarium wilt were identified to provide references for controlling banana Fusarium wilt effectively by using Trichoderma spp. 【Method】Three inoculation methods （viz. Inoculation of the pathogen ahead of the Trichoderma spp.； inoculation of the Trichoderma spp. ahead of the pathogen， inoculation of the pathogen and the Trichoderma spp. at the same time） were used to mensurate antibacterial effect of Trichoderma spp. strains on banana Fusarium wilt. 【Result】Under the three different inoculation methods， the Trichoderma spp. strains of 0026Ⅰ， 0024Ⅱ and 0018Ⅱ① had the highest antibacterial effects， with the antibacterial rates of over 90.00%， followed by 0023Ⅰ②、0028Ⅱ② and 0025Ⅱ with the rates of over 80.00%. 【Conclusion】The Trichoderma spp. strains of 0026Ⅰ， 0024Ⅱ， 0018Ⅱ①， 0023Ⅰ②， 0028Ⅱ② and 0025Ⅱ are all applicable in biological control of banana Fusarium wilt. |
