Cultivar susceptibility and control of angular leaf scorch in grapevine
Background and Aims
Angular leaf scorch (ALS), caused by the fungus Pseudopezicula tetraspora, is an exotic disease threat to the $45 billion Australian wine industry. Research was undertaken at the Cornell University New York State Agricultural Experiment Station in Geneva, NY, USA to develop contingency plans for the Australian wine industry in the event of an ALS incursion.
Methods and Results
Evaluation of Vitis vinifera cultivars widely grown in Australia revealed that Riesling, Sauvignon Blanc, Cabernet Sauvignon and Pinot Noir have moderate to high susceptibility to infection by P. tetraspora. The fungicides trifloxystrobin, pyraclostrobin and tebuconazole were shown to be effective at controlling ALS. A drastic pruning eradication strategy was successfully validated for ALS, resulting in no disease recurrence within 3 years of the initial eradication protocol.
Conclusions
Cultivars grown in Australia ranged in susceptibility to ALS. Fungicides available in Australia are effective and could be used to control ALS in the event of an incursion. The drastic pruning strategy will be included in the Australian Viticulture Industry Biosecurity Plan for potential implementation as part of an incursion response.
Significance of the Study
This research contributes to the biosecurity capability of the Australian viticulture industry and to improved industry preparedness. It has the potential to reduce production losses and vineyard re-establishment costs, while maintaining the competitive advantage conferred by freedom from exotic diseases.
期刊介绍:
The Australian Journal of Grape and Wine Research provides a forum for the exchange of information about new and significant research in viticulture, oenology and related fields, and aims to promote these disciplines throughout the world. The Journal publishes results from original research in all areas of viticulture and oenology. This includes issues relating to wine, table and drying grape production; grapevine and rootstock biology, genetics, diseases and improvement; viticultural practices; juice and wine production technologies; vine and wine microbiology; quality effects of processing, packaging and inputs; wine chemistry; sensory science and consumer preferences; and environmental impacts of grape and wine production. Research related to other fermented or distilled beverages may also be considered. In addition to full-length research papers and review articles, short research or technical papers presenting new and highly topical information derived from a complete study (i.e. not preliminary data) may also be published. Special features and supplementary issues comprising the proceedings of workshops and conferences will appear periodically.
