| Abstract | The potential of the biofumigant crops Indian mustard and canola (cv. Dunkeld) to replace methyl bromide (MeBr) and metham sodium for the control of root pathogens on Shiraz on Ramsey rootstocks was evaluated in a commercial grapevine nursery in the Riverland district of South Australia. The application of MeBr and metham sodium resulted in a significant 78% and 40% increase, respectively, in the percentage of first grade vines at harvest. In contrast, Indian mustard and canola incorporated into the soil at equivalent rates of 12.2 and 9.8 t dry matter per ha, respectively, had no significant effect upon the percentage of first grade vines. There was a significant reduction in vine establishment in the plots treated with Indian mustard (87.5%), compared to the control (93.5%). This reduction was related to a significant increase in the number of Pythium propagules in soil in the plots treated with Indian mustard and canola. Pythium spp. were isolated from >86% of stunted vines in the brassica amended plots. MeBr and metham sodium caused significant reductions in the number of Pythium propagules in the soil and caused significant reductions in the incidence of Cylindrocarpon spp. and Rhizoctonia spp, in the first grade vine roots at harvest. These results demonstrate that, at the rates of incorporation, Indian mustard and canola were unable to replace the beneficial effects and economic returns of MeBr or metham sodium on nursery grapevine growth. |

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.
