Abstract

Blood disease bacteria (BDB) caused by Ralstonia solanacearum Phylotype IV (Pseudomonas solanacearum) is one of the most important diseases on banana. Using biological agents such as arbuscular mycorrhizal fungi (AMF) to control BDB is still not maximal result, based on that need to search a potensial indigeneous AMF specific location. The aim of this experiment were to study the stability of formulated AMF indigenous to control BDB and to increase growth of banana seedlings. This research was arranged by Factorial in Randomized Complete Design (RCD) on green house experiment with 5 replicate. The treatment consist of 2 factors : 1) enrichment of carrier of AMF, sand with rock phosphate (0, 10, 20 and 40 %). 2) incubation periode (0, 1 and 2 months). Banana seedlings were intruduced with formulated AMF at planting date. Two month old banana seedlings were inoculated with Ralstonia solanacearum Phylotype IV. The parameter were observed include: incubation periode, disease insidence, disease severity, discoloration of pseudostem, population density of Ralstonia solanacearum Phylotype IV, colonisation degree of AMF on banana root, spore density on rhizosphere, growth of banana seedlings.The results showed that all formulated AMF introduced on banana seedlings reduced BDB development and increase banana growth compare with control plants, especially the formulated AMF enriched with 30 % rock phosphate.Key Words: arbuscular mycorrhizal fungi, blood disease bacteria, biological controll agents, banana

Abstract

Using biological agents to control fusarium wilt is still not maximal result, based on that need to search a potensial indigeneous biological agents specific location. The experiment conducted to study the role biological agents of arbuscular mychorrhizal fungi indigenous to control fusarium wilt diseases. Twenty four isolates were evaluated for the potensials to reduced fusarium wilt incidence. This research was arranged by Randomized Block Design (RBD) on green house experiment. The aim of this research is to investigate the ability of arbuscular mychorrhizal fungi isolates to reduce fusarium wilt on banana seedling. The results showed that all arbuscular mychorrhizal fungi isolates indigenous from healthy banana rhizosphere reduced fusarium wilt development and increase banana growth.Three isolates (Gl1KeP4, Gl1BuA4, Gl2BuA 6) could control Fusarium wilt until 100% with longer incubation periode and lower disease of banana seedlings as Plant Growth Promoting Fungi. Key words: Arbuscular Mychorrhizal Fungi Indigenous, Fusarium Wilt, Musa sp
