SWD Detected in OSU Wooster Vineyard August 27 2015 by Dave Scurlock, OSU/OARDC Viticulture Outreach Specialist SWD or Spotted Wing Drosophila are most prevalent in the vineyard when the brix level of the grapes reaches around 15-16 brix. Most all of our grapes are in this range with the exception of a few. See Fruit Maturity in this issue of OGEN http://ohiograpeweb.cfaes.ohiostate.edu/sites/grapeweb/files/imce/pdf_events/grape%20maturity_for%20website_18%20aug %202015_0.pdf The SWD were actually trapped in the Chambourcin grapes and the numbers last week were approaching 14 brix. You can see that there is a need to put the SWD traps in early enough to be able to detect the early SWD. These insects are small but left unchecked they can cause rotting of your otherwise sound fruit. Secondary organisms can then enter and really make a mess of things. There are several insecticides available to you to control these insects and they all have varying PHI s, pre harvest intervals and most but not all of them are restricted use pesticides. Here is a link to the SWD fact sheet http://entomology.osu.edu/welty/pdf/swd_ohio_handoutv8.pdf Below are some pictures of our recent captures in the vineyard. Most of you will be able to detect the males without a stereo dissecting microscope but the females identifying serrated ovipositor is very difficult to identify without a strong magnifying lens or microscope. I have included a couple of bogus flys that resemble the male SWD but are not. Please put out traps and check them regularly to prevent your crop from being destroyed. These little insects have caused millions of dollars of damage to brambles and they can do the same thing in grapes. If you can see them flying around, it is already too late.

OARDC Vineyard Update by David Scurlock, Viticulture Outreach Specialist OSU/OARDC Grape Phenology: Cab franc August 28 2015 What a difference a month makes. None of the Vinifera sampled, Cab franc, Chardonnay or Riesling, at the end of July showed any signs of veraison or berry softening. In fact they were totally green and hard as marbles. For the extremely light crop they were carrying I would have expected some signs of veraison. Now, toward the end of August, they have made the most dramatic color change as you can hopefully see in the pictures. Marquette was 99% colored at the end of July as well as Regent so you will not be able to detect the 1% color change made by these 2 varieties in the last month but most all of the other varieties really made a dramatic change. We do have some shot berries(berries that just do not develop) on the Frontenac grapes. I do not think it is enough to make a quality difference at harvest time.

Take a look at the data in the weather chart above, Wooster was: 2.7 inches in precipitation below the 10 year average 1.5 0 F below the 10 year average for Average Maximum Temperatures 2.5 0 F below the 10 year average for Average Minimum Temperatures 104 GDD below the 10 year average for August GDD 106 GDD below the 10 year average from April 1-August I think that we still have the potential to have good quality fruit despite all the negative weather numbers. In math multiply 2 negative numbers and what do you get? That s right! A positive number! Given that we were in a drought condition the last 5-6 weeks it is a good thing we had cooler than normal temperatures or the old and new vines may have been cooked and we would have seen more vines collapsing this summer than we did. There is always s something to be thankful for and farmers are the best with rolling with the punches.
Pest & Disease Situation Weeds Conditions have been ideal for weed growth this growing season with many glufosinate products such as Rely, Cheetah or Forfeit, burn down herbicides, being scarce again this season. We will have to do some investigation into this to be more prepared for next season or change our methods/thinking on weed control. Cultivation was used extensively in the northeast part of Ohio to prevent herbicide damage to the fruit near the ground with really good results. Cultivation has its limitations too. Potential soil erosion, you have to have the equipment and the process may have to be repeated a couple of times so there is also the cost of labor. The alternative is no fruit or damaged fruit and the potential of herbicide damage on the green shoots being brought up for trunk replacements. This is a great example of how our grape growers adapt different cultural practices to meet the changing challenges that winter injury produces. Insects We have been trapping for SWD and now is the time to put out traps in your vineyard to trap and identify this pest. We caught and identified the SWD in black raspberries in the middle of July, so they are here. This past week we caught 5 males and 5 females SWD in the Wooster vineyard. There are many insecticides with varying PHI s to control these insects. We applied Baythroid @3oz/A, on our Wooster vineyards this week. Baythroid has a 3 day PHI. Disease-Downy is still an issue in Ohio vineyard this year Downy mildew continues to be a problem across the state. Early in the growing season we had ideal conditions for downy mildew development and it was very difficult to get into the vineyard to control it. I am seeing downy across the state and every effort is being made by growers to prevent it and or burn it out. In a previous OGEN, http://ohiograpeweb.cfaes.ohiostate.edu/sites/grapeweb/files/imce/pdf_newsletters/ogen20150512%2813%29.pdf, Dr. Mike Ellis mentioned Zampro, a new chemical with a new chemistry, that has had good results from Dr. Wayne Wilcox s research. Zampro is a cost effective material for late season downy mildew. It has a PHI of 14 days. It is listed in the 2015 Midwest Small Fruit and Grape Spray Guide. The following is an excerpt but for more details see the link above from the May 12 2015 OGEN newsletter. a. Relatively new downy mildew-specific product, Zampro. Although Zampro received US- EPA registration in September 2012, it is still not registered in the sovereign state of New York. Zampro is a combination product that contains two active ingredients: (i) dimethomorph (a fungicide that is in the same group as the active ingredient of Revus, i.e., Group 40); and (ii) ametoctradin, which is new chemistry unrelated to any other fungicide now on the market. The Group 40 materials have some post-infection activity but are not absorbed well by plant tissues and consequently are strongest in a protective mode. Anecdotal observations suggest that ametoctradin has significant post-infection activity in addition to protective activity, although publicly-available data on such issues are limited. One good thing that could be said about the 2014 growing season in the Finger Lakes region is that it provided an excellent opportunity to test the efficacy of downy mildew fungicides. We ran our trial in a block of Chardonnay vines, in which (to put pressure on the products and for convenience in scheduling with our other trials) we sprayed most treatments at 2-week intervals. Unsprayed vines were defoliated by September and were killed to the ground this winter
(bummer). However, season-long sprays of both Zampro and Revus Top provided virtually complete control of downy mildew, with only single spots developing on one leaf out of every 20 to 30. No other products looked this good when applied similarly. (Note: We obviously do NOT recommend using any one product season long, but it s hard to evaluate the activity of individual products when we use them in a rotational program on the same vines). Under side of leaf infected with downy mildew Advanced downy mildew picture taken on vinifera June 29 2015. Same condition exists as of July 29 2015.
The weather conditions have continued to be favorable for downy infection so keep the vines protected. Mancozeb protects against black rot, anthracnose, phomopsis and of course downy mildew but the PHI for most varieties has passed. Phosphorous acid can have some kick back on downy if you get it early enough after an infection. There are several different brand names for this such as Agri-Fos, Aliette, Legion, Phostrol, ProPhyt, Rampart and Topaz. An excerpt from Dr. Mike Ellis s 2015 spray program on downy mildew control: Downy Mildew The strobilurin fungicides (Abound, Sovran and Pristine) provided good to excellent control of downy mildew when they were first introduced. Several reports from various areas in Europe and, most recently from Virginia indicate that the downy mildew pathogen has developed resistance, or is at least less sensitive, to the strobilurin fungicides. Growers that have used strobilurin fungicides for several years and have made several applications per year need to consider the possibility of not using strobilurin fungicides for downy mildew control. If resistance to downy mildew is present in your vineyard and you are using strobilurins to control other diseases, they should be tank mixed with another fungicide with activity against downy mildew. Alternative downy mildew fungicides include: Mancozeb, Captan, Ridomil Gold MZ, Ridomil Gold Copper, Revus, Presidio, Ranman, Forum, a copper fungicide or a phosphorous acid (phosphite) fungicide. Pristine still provides good control of powdery mildew when used alone and was the only material that would control almost all of our major disease when used alone. Unfortunately, if resistance to downy mildew is present, it should be combined with an effective downy mildew fungicide. If you have any disease questions please call Dr. Mike Ellis at 330-263-3849 or email at ellis.7@osu.edu Cultural Practices: We have applied 9 cover sprays to the vineyards in Wooster. We are checking our sugars, ph and acids weekly. Trapping and regular scouting of the vineyard looking for any unusual developments occurs twice a week. The nets were applied in early August. Grower Observations: Harvest has begun in southern Ohio and quality and yields look good on some of the hardier varieties. Nutritional deficiencies show up in years when we either have too much water of drought conditions. Both affect the ability of the vine to take up nutrients. Too much water and nutrients are leached or too dry and the vine cannot take up the nutrients. Everything is moderation. Japanese beetles and Phylloxera seem to have gathered the most attention this year but I think we are looking past the potential problems from SWD. We can apply sprays for them without trapping for them but we can be just wasting money. If we trap and identify we have a problem we can treat it more cost effectively. Growers feel the traps may attract SWD that may not have been there in the first place. If you can see them, IT S TOO LATE. THEY ARE SMALL, BUT MIGHTY. The rotting they will cause can be devastating.
2015 Grape Maturity at OSU Research Vineyard -- New addition to Buckeye Appellation Website Imed Dami and Diane Kinney, Viticulture Program, Department of Horticulture & Crop Science, The Ohio State University. The OSU Viticulture Program has initiated a new outreach activity by posting fruit ripening of grape varieties grown at the OSU research vineyards on our new website, Buckeye Appellation (ohiograpeweb.cfaes.ohio-state.edu/home). You may be interested in learning about ripening of new grape varieties or you may be curious to see how the fruit composition numbers compare with those of your own grapes. Please click the link below and check out the weekly progression of grape ripening of familiar and new varieties in our research vineyard. We hope you find this resource informative and helpful to your business. ohiograpeweb.cfaes.ohiostate.edu/sites/grapeweb/files/imce/pdf_events/grape%20maturity_for%20websi te_18%20aug%202015_0.pdf
Harvest Time is Here, and So is Summer? by Dave Scurlock, OSU/OARDC Viticulture Outreach Specialist Remember the spring of 2012 when March and April traded places? We had several days with temperatures in the 80 s in March and then it went cold on us in April. March 2012 averaged about 3 0 F warmer than April and you just knew things were happening a little too early and the potential for something bad to happen was there. This year we have been running a little behind all summer in growing degree days, and August, which is usually our hottest month, has been unusually cool. The forecast for the first week in September is for temperatures in the high 80 s in northern Ohio and I am sure we will be in the 90 s in southern Ohio. What does this mean? Well, for those of you who have fruit, this is great! The usual scenario is when fruit is making its final ripening push into September, the rains come and the potential for fruit rots increases. We can still use some rain but in moderation at this time of year. September can make or break the season. We have no way of telling what October may bring but October has saved many poor ripening years too by extending the season. The long term average killing frost date is October 10 th. When the frost date is delayed until the end of October, late ripening fruit has the best chance of reaching its peak and the vine has more time to accumulate carbohydrates to go into the winter in a healthy status. Maturity numbers are looking really good (see Fruit Maturity information in this issue) and the potential to produce a high quality grape is there. Continue to take 100 berry samples for each variety you are planning to pick at least a couple times of week and the closer your numbers are to peak, you will want to samples every other day. Try to take your samples at the same time of day for consistency of comparisons of samples. Typical berry samples can average 1-2 brix higher than the actual must sample your winemaker takes from the crushed grapes. The difference comes from berries deep in the cluster that are not as mature and sample size. 3 reps of 100 berries per variety will give you a better average than just one 100 berry sample. That stands to reason but it also requires more time in taking the sample and analyzing the sample in the lab. I like to take berry samples from the interior of the canopy more than the exterior hoping that it will run a little closer to the must data. Berries need to be sampled from both sides of the canopy and from the top, middle and bottom of the cluster for a good representative sample. Weigh the potential for better maturity with the predicted weather forecast. It is a lot easier to deal with sound fruit with near perfect numbers than fruit with perfect numbers but 20% or more rot. Our growers have done a great job again this season given the cards that have been dealt. Killing winter temperatures that killed a lot of vinifera back to the snow line in the northeast. Many growers with French hybrids and American varieties do have fairly nice crop this year. Spring rains that made it difficult to protect against disease, weeds and insects. Downy and powdery mildew, phomopsis, anthracnose and black rot were evident in vineyards this year.
Phylloxera has been seen across the state more this year because of the inability to get in the vineyard to apply those first early sprays. Summer drought in late July through August in many areas of the state may have helped to slow growth down in the vineyards along with cool nights to ripen fruit. The drought may be responsible for more bird predation on the fruit. Dry years just seems to bring the birds out of the woods in search of food and moisture. Invite your winemaker to the vineyard to see the condition of the fruit and taste the fruit in the vineyard. This is an extremely important time for good communication between the grape grower and winemaker so we can make the best harvest decision and wine possible.
Ohio Superberry & Winegrape Field Night by Dave Scurlock, OSU/OARDC Viticulture Outreach Specialist, Dr. Gary Gao, OSU Small Fruit Specialist and Ryan Slaughter, OSU Research Assistant What a beautiful evening for the Superberry and Winegrape Field Night. A typical August evening may be in the upper 80 s to low 90 s this time of year. On this particular evening on August 20 th, we had mid 70 s and a perfectly clear sky. There were approximately 35 in attendance from all around the state.
Dr. Gary Gao was the host and Superberry Expert for the evening along with his Research AssistantS Ryan Slaughter, Kaitlyn Williams and Michael Daniels. As usual we had a nice meal before the program began. Dr. Thomas Worley gave some welcoming remarks to the attendees and explained about the various research activities that are being carried out at the Piketon South Centers Research facility. Aquaculture and Aquaponics caught the attention of the crowd and Dr. Worley explained that they are combining the two disciplines to grow sustainable fruits and vegetables in the greenhouse.
The field tour began with the winegrapes where berry, petiole and soil sampling were simply explained and the benefits and timing of each were explained. Cultural practices for the remaining of the summer and into the fall were discussed and questions were fielded from the
attendees. Kaitlyn Williams (center), student research assistant at the South Centers this summer explained the techniques for trapping and identifying the Spotted Wing Drosophila.
Michael Daniels, student research assistant, discusses bird netting construction and considerations over different crops The evening continued with a tour of the Elderberries, black berries, blueberries and finished in the field with the Aronia and Goji berries discussing cultivation techniques for all the crops, harvesting time and requirements, and considerations to think about when marketing the fruit, whether fresh of processed.
The wagon was loaded and we headed back to the conference room for final remarks, questions and answers.
If you have never attended a workshop or field day at the Piketon South Centers, you are really missing out. Good friends, good food and most of all good information were shared. These workshops and field nights are always interactive and everyone goes home with information that they can add to their arsenal.
NE Ohio Grape Field Day August 27 2015 by Dave Scurlock, OSU/OARDC Viticulture Outreach Specialist We have really been Blessed with some of the most Beautiful weather I have ever experienced in August. The evening was perfect if not even a little on the cool side for the NE Ohio Grape Field Day. The First stop was held at the Ferrante s vineyard where Tom Todaro is carrying on some of his master s research work under the direction of Dr. Imed Dami. Dr. Imed Dami, along with Nick Ferrante discussed some of their strategies for managing winter injured vines. Nick Ferrante presented his methods on hilling & dehilling practices. The process requires at least 2 passes with the Maximus plow pictured below. *Photo 1 The goal is to get the hill up 18 to 24 inches to protect the graft union Photo 1 and as much of the bottom portion of the trunk and buds with soil. The soil along with the snow, that accumulates and insulates the vine, both provide protection from the extreme winter cold. In the event of a severe winter, the portion of the vine that was covered should not be killed. If the top is killed, new trunks can be reformed from the protected portion of the vine. This was the case the last 2 winters of 2014 and 2015. The next step is the hills need to be taken down as soon as the soil is fit in the spring to prevent scion rooting. Pictured below is the Clemens hoe that is used to dehill the vines. In this picture of the Clemens hoe the attachment for weed control is attached. *See photo 2
Photo 2 Photo 3 Dr. Imed Dami discussed the retraining experiment that is being done by Tom Todaro for his masters research project. There are 3 training systems in the experiment, the Fan, VSP and a combination of the
Fan and VSP. All 3 training systems employ multiple trunking. The main difference between the 3 systems is the Fan system is allowed to fruit to help slow the growth of the shoots down and the other 2 systems are totally defruited in an effort to reestablish the training system quicker and hopefully put it back into full production the following year. The VSP and the combination system will be ready to prune next year with minimal effort and the crop will be located where it is supposed to be in the 36-40 inch fruiting zone. *See Photo 4 below Photo 4 VSP training system
The Fan system is producing a crop this year but there will be some effort involved to hand harvest the crop located within 2 feet from the ground. *see photo 5 Normal training & 6 Fan system Photo 5 Arrows indicating Fruit in normal training Predicted yields are estimated at 2 to 3 tons per acre on the fan system. Normal training in photo 5 is merely bringing up at least 4 canes, leaf pulling the fruiting zone near the bottom to expose the fruit and training the shoots upwards. Next spring, canes will be selected and laid down as fruiting canes.
Photo 6 Fan system *Note: Weed control was all by cultivation with the Clemens tool. Herbicides could not be used since the fruit was so near the ground level to prevent damage. Photo 7 Matt Meineke on burying canes Stop #2 was M Cellars. *see photo 7 above Matt Meineke presented information on how M Cellars
changed their winter protection strategies for vine protection through the practice of burying canes. Matt discussed that they laid down a couple of canes and in the direction that the canes indicated they wanted to go and then hilled them with soil. The canes were then removed from the soil using pitch forks to find and lift the canes from the hills and trained back onto the fruiting wire. Matt stated that he expects 80% plus of a full crop and said he would continue this practice. It s like insurance, you hope you don t have to use it but it is there, if you need it. Matt also stated that it cost around $600 dollars an acre to bury the canes and retrain them. Kosicek Vineyards was stop 3, where we were hosted by Tony Kosicek to a picnic style dinner on the deck.
Dr. Erdal Ozkan, from OSU s Department of Food, Agriculture, and Biological Engineering, had an interactive workshop on air blast sprayer calibration and optimizing spray coverage for better control of pests and diseases. Dr. Ozkan showed us the math behind sprayer calibration and how to use water sensitive paper strips to check our spray coverage. Dr. Ozkan discussed the various parameters such as tractor speed, pressure regulation, GPA and recent nozzle advancements to increase coverage and reduce drift. Mike, from Fred s Water Service supplied several different sprayers and the tractor used in the sprayer demonstration, so a special thank you is extended to Fred s Water Service in Madison, Ohio for supplying the air blast sprayer for this workshop. Two hours of Commercial & Private CORE Pesticide Applicator Credits were earned by the attendees. Another special thank you to Dave Marrison, for organizing the event, Les Ober, for providing an update on the SWD, and Eric Draper, for providing additional information on chemical application and providing assistance during the sprayer demonstration.
