Enhancing the Biological Control of Rice Seedling Disease by Adding Specific Carbon Sources into the Bacillus cereus D324 Formulation in Water-Seeded Rice

摘要: Utilization of carbon sources by Bacillus cereus D324, a biological control agent, and Pythium species, which causes rice seedling disease, was studied with the objective increasing efficacy providing agent specific beneficial sources. D-galactose, D-sorbitol, D-mannitol were poor for spp. growth but good B. D324 growth. Growth in chamber seeds coated amended sources, such as D-galactose showed significantly enhanced emergence compared to only D324. Field trials that both yield increased, when above added seed coating formulations. This result indicated amending formulations could increase field.
