Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Vineyard Nutrition Study

Creator:: Baham, John and Righetti, T.
Abstract:: Oregon State University researchers are expanding their study of mineral nutrition in winegrapes as part of a project sponsored by the Wine Advisory Board. Further research is justified because of increasing grower interest in nutritional factors that affect production and quality. Winegrape growers utilize Oregon State University's Plant Analysis Laboratory...

Evaluation of Grape Powdery Mildew Forecasting Programs Grape (Vitis vinifera 'Chardonnay') Powdery Mildew (Uncinula necator)

Creator:: Pscheidt, J. W., Wallace, L. D., Hall, T., and Mahaffee, W.
Abstract:: Three forecasting programs for scheduling fungicide applications were selected for comparison with the standard Oregon phenology based program. The California (Gubler-Thomas, UC-Davis) program used leaf wetness and temperature early in the year to predict ascospore infection periods and only temperature during the summer to predict conidial infection periods. The New...

OSU Wine and Grape Research and Extension Newsletter : January 2008

Creator:: Oregon State University. Extension Service
Abstract:: Winter provides many opportunities for viticulture and enology programming across Oregon, the Pacific Northwest and beyond. The vines, although dormant, need pruning and the winery operations continue. This month, we’ve decided to focus on important considerations in both the vineyard and winery. An article on pruning operations by Dr. Patty...

The Urethane (Ethyl Carbamate) Voluntary Reduction Plan - an Update

Creator:: Scanlan, Richard A. and Watson, Barney
Abstract:: Urethane is a by-product of the fermentation and distillation of alcoholic beverages. In recent years, concern has been expressed over its presence in such beverages because of studies which demonstrate that urethane can cause cancer in various animal species and, as a consequence, must be regarded as a potential carcinogen...

Amino Acid and Amine Content of Northwest Wines and Strategies to Limit Amine Formation [1994-1995]

Creator:: Daeschel, Mark A., Gloria, M. Beatriz A., Simon-Sarkadi, L., and Watson, Barney
Abstract:: Wines, specifically those in which lactic acid bacteria can grow can cause transient toxic effects due to the formation of biogenic amines such as histamine and tyramine. Some people specifically avoid red wines because they are more often associated with headaches and other discomforts. An understanding of the origin, occurrence...
