Climate, Weather and Wine Grapes

Climate, Weather and Wine Grapes
This preliminary report offers a snapshot of Pacific Northwest wine grape growers’ observations, thoughts, concerns, and priorities for their crops. Using the concept mapping process, they identified a set of seven key areas where uncertainty makes managing their production systems difficult: pest & pathogen dispersion; pest & disease management; government oversight; labor; vineyard micro climate; harvest logistics; and winemaker relations.

Managing Spotted Winged Drosophila in Commercial Fruit Production

Managing Spotted Winged Drosophila in Commercial Fruit Production
Fruit flies native to the U.S. primarily lay eggs in soft, rotting fruit and cause little to no economic loses to undamaged fruits. These fruits flies are considered a nuisance pest to farmers unless the fruit has been previously injured. Spotted winged drosophila (SWD), Drosophila suzukii, on the other hand, is an invasive fruit fly that prefers to lay eggs in healthy, maturing fruit. It is native to Southeast Asia including China, India, Japan, Korea, and Thailand (Walsh et al., 2011), where the climate is similar to the Midwest.

A Review of Cold Climate Grape Cultivars

A Review of Cold Climate Grape Cultivars
There has been interest in growing grapes in the upper Midwest and other cold climate regions of North America. One of the problems growers face in these regions is selecting cultivars (cultivated varieties) that will withstand severe winters, mature in short growing seasons, and be productive. As grape acreage increases in cold climate regions, too often cultivar selections are being made based upon testimonial or anecdotal information. With the high costs of vineyard establishment there is an increasing need for a standard reference to assist growers in selecting best adapted cultivars.
