| Abstract | Three antagonistic bacteria, Streptomyces misionensis strain PMS101, Bacillus thermoglucosidasius strain PMB207, and S. sioyaensis strain PMS502, were tested for sensitivity to the foliar fungicide Sporgon (a.i. 50% prochloraz-Mn complex) and for efficacy in controlling Fusarium diseases of lily. Results showed that the growth of all three antagonistic strains of bacteria was completely suppressed by Sporgon at a concentration of 500 μg/mL, but B. thermoglucosidasius strain PMB207 and S. misionensis strain PMS101 were unaffected at concentrations of 100 μg/mL or lower. A large-scale trial in an automated and environment-controlled commercial greenhouse showed that treatment of scale bulblets of lily with Sporgon (100 μg /mL) and B. thermoglucosidasius strain PMB207 (1–1.2 × 10$^{7}$ cfu/mL) or 100 μg/mL Sporgon and S. misionensis strain PMS101 (1–1.4 × 10$^{7}$ cfu/mL) resulted in a significant reduction (P < 0.05) in the incidence of seedling blight caused by Fusarium proliferatum. The difference between these two treatments was not significant (P > 0.05). Results of the greenhouse and field experiments showed that treatment of scale bulblets or one-year-old bulbs of lily with B. thermoglucosidasius strain PMB207 (1–1.2 × 10$^{8}$ cfu/mL) or S. misionensis strain PMS101 (1–1.4 × 10$^{8}$ cfu/mL) without Sporgon was also effective in the control of basal rot caused by F. oxysporum f. sp. lilii. These studies reveal that B. thermoglucosidasius strain PMB207 and S. misionensis strain PMS101 are biocontrol agents which have potential for use in the commercial production of lily bulbs, as they can be used alone or in combination with the fungicide Sporgon at low concentration (<100 μg/mL). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
