Dr. Tony K. Wolf, Viticulture Extension Specialist, AHS Jr. Agricultural Research and Extension Center
Our Viticulture Research/Extension Associate, Fritz Westover, will be pulling stakes and moving to Texas early next month. His wife, Sabrina, has recently completed her PhD studies and has accepted a position in Houston. Fritz will continue his viticulture extension role with Texas A&M University, and will have responsibilities in the Gulf region of Texas. We will dearly miss Fritz’s friendship, appreciation of wine, and his professional contributions to our viticulture program. He is working to finish up some Macromedia Breeze presentations on dormant vine pruning, several of which can now be viewed/played from his website: http://faculty.vaes.vt.edu/westover. Fritz has been the ‘”Front office” person here at the AREC for handling many of the requests that come in for viticultural information. Since his hire in January 2005, he has been a regular contributor to Viticulture Notes, a speaker at vineyard meetings, a co-presenter at our basic grape production shortcourses, worked closely with many of our Cooperative Extension agents in on-site visits, and has been actively involved in our research projects. The viticulture research/extension associate position was approved for re-filling and we are now actively seeking a pool of qualified applicants for the position. If any VN readers are interested, please view the position description online at http://www.jobs.vt.edu (posting # 061204).
I must also regretfully pass on the news that Ashley Myers, who came on board in January 2006 as our grape pathologist, has decided to resign to return to her family in North Carolina. Ms. Myers will be leaving in mid-January. We hope to refill the pathology position as soon as possible, but must await administrative approval to re-advertise the position.
We wish both Fritz and Ashley well in their respective endeavors.
Fritz Westover, Viticulture Research Extension Associate, Virginia Tech
The 2006 season offered its score of challenges to grape ripening, especially for red varieties in many areas of the state where late season rains persisted. In general, the growers I have interacted with this year have been most concerned with seasonal conditions after veraison and leading into harvest, such as rain, diseases, or fruit chemistry imbalances. Yet another influx of inquiries occurred much earlier in the season, regarding poor fruit set in many red vinifera varieties; most notably in Merlot, Cabernet Franc and Cabernet Sauvignon, and in some cases, with the white hybrid Traminette.
Poor fruit set may affect not only yields, but also the uniformity of ripening in grape clusters if variability is introduced. Millerandage or “Hens and Chicks” is a condition recognized as small, “shot” berries borne on the same cluster with normal-sized berries as well as unfertilized swollen green ovaries (3). Many factors can affect fruit set in the vineyard, including cool, wet, or windy conditions during bloom, crop load, water, heat and other stresses from the previous season, and nutritional deficiencies. A survey of those factors was initiated during the 2006 season to determine the potential causes or commonalities of poor fruit set in Virginia on a case-by-case basis. Our inquiries with growers indicated that some of the poor fruit set may have occurred due to hot, dry weather during bloom, while others may have been the result of limited carbohydrate reserves in vines resulting, perhaps, from a dry 2005 season followed by dry conditions in spring of 2006. Still, other vineyards did not report excessive temperatures or rain during bloom, nor did plant tissue analysis (petioles) at bloom show deficiencies in boron or zinc, both of which are known to affect fruit set and occurrence of millerandage. Our research group was made aware of investigations of the role of molybdenum (Mo) on fruit set in Australian studies during a visit by Dr. Peter Dry of the University of Adelaide in spring of 2006. Although this problem (referred to in Australia as the “Merlot problem”) is most prevalent on own-rooted Merlot vines, we decided this was a good opportunity to investigate the levels of Mo in Virginia vineyards. This article discusses some of the factors that affect Mo uptake by grapevines and summarizes the results of our preliminary survey of Mo content in grape petioles.
Why is Mo important? Molybdenum is a trace element found in soils and is necessary for the growth and development of plants. In grapevines, Mo has been associated with the development of functional seeds and is thus considered to be important for pollination and/or fertilization (4). Several factors can influence Mo uptake by grapevines. Availability in soil is dependent upon soil pH. The molybdate anion (MoO42-) is more available in alkaline soil and uptake is greatly reduced at pH 5.5 or lower, with maximum adsorption onto positive charged metal oxides occurring at pH 4.0 to 5.0 (1). Molybdate is generally more available in soils with higher organic matter and can be leached in sandy, low organic matter soils. Mo uptake is also affected by iron and aluminum oxides in soil and by competition from sulfate (SO42-) anions. Other data shows that Mo is involved in phosphorus (P) transport in roots. Low P transport into roots may facilitate molybdate accumulation in roots, suggesting that low soil P may inhibit Mo uptake into foliage (1). Additionally, Mo deficiencies in Australia were predominantly found in own-rooted vines. Those planted on American rootstocks Schwarzman (Vitis riparia x V. rupestris) and 140 Ruggeri (V. rupestris x V. berlandieri) were not as greatly affected, implying a genotypic difference in uptake efficiency. Other factors that will reduce nutrient uptake into roots, such as wet or cool soil conditions, may also reduce uptake of Mo. A good example of this is the yellowing of young shoots during cool, overcast spring weather, associated with low uptake of nitrogen and potassium.
In Virginia soils, organic matter is not typically limiting, however, low pH, and additions of sulfate via gypsum or Epsom salt would theoretically predispose vines to reduced Mo uptake. The likelihood of inducing Mo deficiency by of all of those factors would be more the exception than the norm in a well-managed vineyard and the use of American rootstocks further limits concerns for Mo deficiency in our region. Nonetheless, all factors must be considered when poor fruit set occurs without explanation.
The survey included a total of 14 Virginia vineyards, comprising varieties of various age, rootstock, and soil conditions. Varieties were chosen to represent those most affected by poor fruit set in 2006 including Merlot (M), Cabernet Sauvignon (CS), Cabernet Franc (CF), Petit Verdot (PV), Carmenere (CM), and Traminette (TM). Controls were included from vineyards not having fruit set problems. Boron (B) and zinc (Zn) were also analyzed to determine if other micronutrient deficiencies were involved in poor fruit set. Samples were collected between 30 May and 28 July of 2006. A modified version of the Mo analysis by Williams et al. (4) was performed by two independent laboratories to detect Mo levels in 36 grape petiole samples.
Levels of Mo ranged from 0.10 to 1.50 ppm from Lab A and 0.10 to 0.48 ppm from Lab B (Table 1). The two laboratory results were similar for 7 of the 13 samples (<0.14 ppm difference) and differences ranged from 0.18 to 1.24 ppm in the other 6 samples. According to standards for Mo in grape established by work in Australia and using the upper level of £0.14 ppm as the deficiency range, only 1 of the 13 samples tested by both labs was considered deficient: CS from Fauquier Co. Lab B’s results suggested that 3 additional samples were deficient in Mo: M from Pittsylvania Co., CM from Fauquier Co., and own rooted TM from Frederick Co. All of the above samples, except for TM, were from vines that showed symptoms of poor fruit set. Samples containing Mo within the range of 0.14 to £ 0.20 ppm included CF from Albemarle Co. (Labs A & B), CF from Rappahannock Co. which both had symptoms of poor fruit set, and CF Frederick Co. and TM on rootstock C-3309, Frederick Co. (Lab B only), which did not show poor fruit set. The mean Mo levels were 0.45 (n = 36) and 0.22 ppm (n = 13) for labs A and B respectively. Boron fell within or above adequate ranges (27 to 54 ppm: recommended is 25 to 30 ppm) in all of the sites tested, as did zinc (36 to 192 ppm: recommended is 30 to 50 ppm).

|*Grape Variety Key: CF = Cabernet Franc, CH = Chardonnay, CM = Carmenere, CS = Cabernet Sauvignon, M = Merlot, PV = Petit Verdot, TM = Traminette, VN = Viognier,|
Other than nickel, the requirement for Mo is lower than any other essential plant nutrient (2). Recent research with Merlot in Australia proposed that vines are deficient in Mo when levels are <0.09 ppm at bloom and <0.14 ppm at veraison, having no significant yield effects when foliar Mo was applied to vines containing >0.14 ppm Mo (4). The challenge with determining crucial levels of Mo lies in the difficulty of accurately detecting such low levels. To add to the complexity, the typical laboratory that provides plant nutrient analyses may not be equipped to detect the low levels of Mo critical for assessing deficiencies.
Levels of Mo in petiole samples varied considerably in 2006. Although a few of the sites appeared to have deficient levels, only one site was confirmed to be deficient by both laboratories. The varieties that were labeled as having deficient Mo levels (£0.14 ppm) by at least one of the labs were also reported as showing symptoms of poor fruit set in 2006, except for those in Frederick Co. In contrast, many other sites that reported poor fruit set were not deficient in Mo. Other sites reporting fruit set problems had Mo levels in the range of 0.3 to 0.9 ppm as well as sufficient levels of B and Zn, suggesting that factors other than mineral nutrition may have been responsible for poor fruit set. Research by Williams et al. (4) showed that foliar applications of molybdenum did not improve fruit set when petiole values were greater than 0.14 ppm, therefore we do not promote the use of Mo fertilizer in vineyards that test above 0.14 ppm unless future research shows improvements for grafted vines in the Mid-Atlantic region.
In the event that future work in the Mid-Atlantic shows that Mo is the primary cause of recurring fruit set problems, there are practical methods to increase Mo content in vines. Foliar sprays are effective because Mo is mobile in both the xylem and phloem. Mo sprays on Merlot in the Australian study did not significantly affect uptake of other nutrients, such as B, Zn, and had no effect on vegetative growth of vines (4). Additionally, the two sprays per season (bloom, veraison) at a rate of 0.64 lbs/acre molybdate and applied in about 300 gal/acre of water did not cause phytotoxicity in vines. Future research will be needed to determine critical levels for Mo in Virginia vineyards before we have reason to expect that different levels are needed. Some trace mineral products that are currently being used in vineyards in the Mid-Atlantic to apply B and Zn, also contain Mo, but it is difficult to distinguish if improvements in fruit set are due to the Mo component. The effects of Mo application have yet to be determined in a controlled study in this region.
