In this version you are able to calculate vineyard yield just like in the first version, but wine yield calculations were also added. Hopefully this tool will allow for better planning and prediction of both grape and wine yield from vineyards. Give it a try at the following link: http://www.dmacc.edu/programs/viticulture/cropcalc/cropcalculatortwo.aspx If you have any questions, let me know.

Upper Mississippi River Valley Viticultural Area Gets Approved! The Upper Mississippi River Valley Viticultural Area was approved by the Federal Alcohol, Tobacco Tax and Trade Bureau. This will be the largest American Viticultural Area (AVA) in the U.S. covering 29,914 square miles in Northeast Iowa, Southwest Minnesota, Northwest Illinois and Southwest Wisconsin. The ISU Leopold Center provided the initial grant funds to establish the project of identifying and applying for this AVA in 2007. The staff at the Limestone Bluffs RC& D in Maquoketa, Iowa did much of the groundwork to complete this project. (Right) The dotted line represents the boundary of The Upper Mississippi River Valley Viticultural Area. Taken from Warren Johnson s Limestone Bluffs RC& D presentation regarding the Development of a Regional Wine Culture in Iowa.

A few more started coming in this week. These voracious adult beetles normally begin to emerge from the soil around mid-june. There is only one generation per year. They normally start to aggregate in large numbers and do most of their feeding from July through September. Grapes are high on the list of the over 300+ species of plants JBs like to chew on. They love to eat grape leaves by eating the top leaf layer of tissue between the veins (skeletonizing). The thicker leaved American varieties are fairly tolerant to their feeding. French varieties and the hybrids are more susceptible. College, 7-25-08) Young vines are the most susceptible and can be (Above) Japanese Beetles feeding on grapes (by Tom Moore, Kirkwood Community 3

completely defoliated when high numbers are present. Very seldom will JBs feed on the berries. Moderate feeding on the top leaves in the grape canopy can be common and often will not cause any economic damage. It is difficult to determine the exact level of defoliation that will cause enough economic damage to warrant an insecticide treatment. Defoliation levels above 15-20% is often used as a rule of thumb to trigger an insecticide treatment. Serious leaf feeding from heavy populations after veraison is more likely to cause economic yield losses. (Above) Adult Japanese Beetle JB bait traps can be purchased and used to monitor the emergence of JBs and relative populations. It is recommended to put the traps on the vineyard edges and not in the vineyard. Trapping is primarily a method of monitoring and not control. Bacillus popillae (milky spore disease) is a biological control agent that has been used to protect grassy areas from large larval populations, but it is ineffective against adults entering the vineyard. Adults are capable of flying great distances and will come into the vineyard from untreated areas. Insecticide applications are usually necessary for control.

(b) Renounce is composed of the active ingredient cyfluthrin which is very similar to the active ingredient of Baythroid XL (B-cyfluthrin). Renounce is labeled for grapes and has Japanese Beetles listed on its label for many crops other than grapes. (c) Repeated use of Sevin insecticide could depress predatory mite populations and promote the outbreak of spider mite populations. JB management options for organic grape producers would include the use of Aza Direct, a neem oil insecticide repellent; the use of Pyganic or one of the many other organically approved pyrethrin type of insecticides and the use of thin woven insect barrier row covers.

My first priority is to improve the mix of downtown business. We currently have the LaSalle Canal Boat and Lock 16 Visitor Center. This attraction draws several busloads of tourists each day. To compliment there stay I am searching for a Winery that desires to enter our market with Tasting Room close to the Center. The City is prepared to work with new business and provide options for vineyard space also. Currently we have two vineyards in the area. Please contact me on my City cell phone at 815-488- 4442 to discuss this opportunity in detail. Thank you, Donald J. Aleksy, 3006 St. James Drive.

Show n Tell (Right) 6-30-09 picture of a Golden Tortoise Beetle, Charidotella sexpuncta submitted by Mike Epps, winemaker at White Oak Vineyards & Winery at Cambridge, Iowa. http://www.whiteoakvineyards.com/ This beetle was found on in their Marechal Foch vineyard. This beetle is not considered an economic pest of grape. It feeds primarily on the leaves of plants in the Morning Glory family of plants, Convolvulaceae. It has the unique ability to change color from a metallic gold to red with black dots, somewhat similar to a lady beetle.

Comments from Readers Mike, just wanted to share that this past weekend the Japanese Beetles have emerged. Young vineyards need to be protected, they can defoliate an acre in about a week if the infestation is bad enough. 7-1- 09 Thanks, Mike Epps, Winemaker White Oak Vineyards LLC 15065 NE White Oak Drive Cambridge, IA 50046 http://www.whiteoakvineyards.com 8

Quote of the Week Despite some anecdotal reports of a surge in drinking accompanying the economic recession, Gallup's annual update on alcohol consumption finds little change in Americans' drinking habits. The percentage of U.S. adults who consume alcohol is fairly steady at 64%, and there has been little change in self-reported drinking volume. --- Lydia Saad, Drinking Habits Steady Amid Recession, 6-29-09: http://www.gallup.com/poll/121277/drinking-habits-steady-amid-recession.aspx Articles of Interest 1.
