The potent microorganisms used for sustainable agriculture in Vietnam has been investigated by Soytong, K. for years. The natural products named synegistic Chaetomium and Trichoderma Biofungicide, Biodegradable nano-elicitor for plant immunity and Biodecomposer for soil revitalization and improvement through fermentation to increase organic matter and fertility in the cultivated soils. The mixture of several strains of powerful Chaetomium for plant disease control to be a broad spectrum biofungicide and enzymatic fungi for biodecomposer are proved to be synergistic fungal community. A novel biodegradable nano-particles contructed from active metabolites of Chaetomium spp named nano-elicitor is discovered to induce immunity in plants eg rice, tomato, durian and citrus. Biodecomposer demonstasrtes as a synergistic group of microorganism producing cellulase, hemicellulase, ligninase and protease that produced from Achaetomium sp., Eurotium sp, Emericella sp, Trichoderma sp., Aspergillus japonicus, Aspergillus terreus and 3 benefit bacteria to degrade organic and inorganic materials, and improve soil revitalization and productivity. Withis some parts of research projects were supported by Ministry of Agriculture and Rural Development in Vietnam.
