White root rot disease caused by Rigidoporus microporus results in major economic loss to rubber plantation in all rubber growing countries including Malaysia. This glasshouse trial was conducted to explore the potential of single and co-inoculation of Enterobacter sp. UPMSSB7 and arbuscular mycorrhizal fungi (Glomus mosseae) with silicon for white root rot disease suppression and plant growth promotion of rubber seedlings. Plants were artificially infected with R. microporus using rubber wood blocks. The results revealed that co-inoculation with silicon significantly reduced the disease incidence and disease severity of foliar and root rot symptoms and also recorded the highest disease reduction compared to control after 24 weeks of artificial infection with R. microporus. The highest stem height, girth size, chlorophyll content, leaf area, shoot and root dry weight, root length, root volume and root surface area were achieved by co-inoculation with silicon. The co-inoculation with silicon also significantly improved silicon content in roots and shoots and leaf nutrient contents (N, P and K). The Enterobacter sp. population density, mycorrhizal spore density and root colonization were increased in co-inoculation with silicon treatment as compared to control and single inoculation treatments. From this study, it was concluded that co-inoculation of Enterobacter sp. and arbuscular mycorrhizal fungi with silicon had potential to suppress Rigidoporus microporus and improve plant growth of rubber seedlings under glasshouse conditions.

由微孔刚毛孢菌引起的白根腐烂病导致包括马来西亚在内的所有橡胶种植国的橡胶种植园遭受重大经济损失。进行了该温室试验，以探索单次和共同接种肠杆菌的潜力。UPMSSB7和带硅的丛枝菌根真菌（Glomus mosseae）用于抑制白根腐病和促进橡胶幼苗的植物生长。将植物人工感染了微孔菌使用橡胶木积木。结果显示，与硅共同接种可显着降低叶面和根腐病症状的发病率和病情严重程度，并且与对照组相比，在用微孔红斑霉菌人工感染24周后，与对照相比，病害减少程度最高。通过与硅共同接种，可获得最高的茎高，周长大小，叶绿素含量，叶面积，枝条和根干重，根长，根体积和根表面积。与硅共同接种还可以显着提高根和芽中的硅含量以及叶片养分含量（N，P和K）。该肠杆菌sp。与对照和单次接种处理相比，与硅处理的共接种增加了种群密度，菌根孢子密度和根定植。从该研究得出结论，肠杆菌属菌的共接种。硅对丛枝菌根真菌具有抑制温室温室橡胶幼苗微孔和提高橡胶苗植物生长的潜力。
