  • Abstract : Objective: The paper was to understand the field resistance performance of different banana varieties and the prevention and control effect of different fertilizers, so as to provide technical reference for the prevention and control of Fusarium wilt.
    Method: Field trials were set up with three treatments: shrimp peptide organic fertilizer + shrimp peptide special protection + shrimp peptide fruit Yekang (simplified as shrimp peptide organic fertilizer treatment), conventional organic fertilizer + microbial preparations (simplified as microbial treatment), and conventional organic fertilizer (simplified as control). Four different banana varieties of Brazilian banana, Guijiao No.l, Nantianhuang, and Yunjiao No.l were selected for the field trial. The disease incidence of Fusarium wilt and the control effects of three fertilizers were investigated during four time periods.
    Result: The disease incidence of four varieties in three treatments varied. The disease incidence of Nantianhuang and Yunjiao No.l were significantly lower than that of other two varieties. There was also significant difference in disease incidence of three treatments. The disease incidence from high to low was control > shrimp peptide organic fertilizer treatment > microbial treatment. The average monthly TR4 pathogen content in heavily infected banana plantation was more than 2 000 copies, while the highest one reached 15 148.9 copies.
    Conclusion: Microbial agents reduced the disease incidence of Fusarium wilt to some content. Nantianhuang and Yunjiao No.l showed the highest disease resistance compared with other varieties. However, their resistance needs to be further improved before practical application.
