摘要：
The fungicidal activity of TCA and cell-free extracts of X. szentirmaii is superior compared to other Xenorhabdus and Photorhabdus species. The effectiveness of TCA and X. szentirmaii metabolites to synergize and enhance fungicidal efficacy of commercial fungicides when combined with them at particular concentrations to suppress growth of Monilinia fructicola and Rhizoctonia solani was evaluated. Fungicidal activity was measured by phytopathogen growth on PDA plates with and without treatments. For suppression of M. fructicola, synergy was observed between TCA when combined with certain concentrations of Elast®, PropiMax®, Regalia® or Serenade®, and for combinations of X. szentirmaii, strain 17C+E, when combined with Abound®. For suppression of R. solani, synergy was observed between TCA combined with Regalia® or Serenade®. TCA combined with X. szentirmaii resulted in synergistic levels of suppression of M. fructicola. Utilizing TCA and X. szentirmaii for enhancing fungicidal activity improves control of phytopathogenic diseases and reduces environmental impact.
