菲律宾香蕉目前受到古巴镰刀菌（Fusarium oxysporum f. sp. cubense Tropical Race 4）的威胁。本研究研究了用球囊菌（Glomus spp）预处理哈兹木霉（Trichoderma harzianum）作为控制Lakatan’香蕉幼苗枯萎病的一种手段。结果表明，施用Glomus对香蕉幼苗生长有显著的促进作用，株高和假茎直径增加，根重增加。单独施用Glomus spp.可以100%保护Lakatan幼苗免受FocR4的侵害，这表明没有萎蔫症状。哈兹霉与球囊菌联合施用对青枯病也有显著的抑制作用，但不具有协同效应。当两种生物防治剂同时施用于香蕉根部时，怀疑存在竞争效应。
Philippine banana is currently threatened by Fusarium oxysporum f. sp. cubense Tropical Race 4 (FocR4). This study investigated the use of Trichoderma harzianum pre-treated with Glomus spp, as a means of managing Fusarium wilt on young Lakatan' banana seedlings. Results showed that Glomus applied basally significantly improved banana seedling growth with increased increment in plant height and pseudostem diameter and heavier root weight. The application of Glomus spp. alone offered 100% protection to the Lakatan' seedlings against FocR4 as indicated by the absence of the wilting symptom. A combination of T. harzianum and Glomus spp. also gave significant effect against Fusarium wilt through delayed disease progression in the seedlings but was not synergistic. Competitive effects were suspected when application of the two biological control agents on banana roots was done simultaneously.
