Interaction among Macrophomina phaseolina, Rhizoctonia solani, Fusarium solani and two symbiotic organisms, Glomus mosseae and Rhizobium japonicum, and their effect on the severity of soybean root and stem rot were investigated by exposing nodulated and non-nodulated seedlings to defined inoculum densities of the various organisms in greenhouse tests. Autoclaved or non-autoclaved Arredondo fine sand with 91 ppm of phosphorus and pH 6.7 was thoroughly mixed with spores or resting structures of the fungi. The mycorrhizal fungus was added at 500 chlamydospores per pot in one layer 5 cm below the seeds. Rhizobium japonicum cells were inoculated directly on the seeds at 5mg/g of seed. The percentage of infected roots, diseased plants, or both increased with increasing levels of inoculum of each fungus. The concentrations at whitch 50% of the roots were infected (ED50) by M. phaseolina were approximately 20x10x10x10 and 150x10x10x10 sclerotia per kilogram of autoclaved and non-autoclaved soil, respectively. For R.solani the ED50s were 1.0x10x10x10 sclerotia per kilogramof autoclaved and non-autoclaved soil, respectively. Macrophomina phaseolina at 40x10x10x10 sclerotia per kilogram of soil interacted additively with R.solani at 1.0x10x10x10 sclerotia per kilogram of soil and with F.SOLANI AT 3.000X10X10X10 chlamydospores per kilogram of soil to increase root and stem rot and to reduce the plant growth response. Root and shoot weight and plant height were reduce more at 45 than at 25 days after planting, and soybean....
