Vole tunnels at the base of a dwarf apple tree. Fruit Crop News John Strang, U.K. Extension Horticulturist and Matt Dixon, U.K. Ag Meteorologist It has been a very mild exceptionally warm and dry fall, but we have finally had a killing frost. Many soils are still exceedingly dry and fruit crops particularly young trees will benefit from one last irrigation. The trees may have dropped their leaves, but the roots still need to have enough water to carry out the biochemical processes necessary for developing their winter hardiness. In September the USDA s National Agricultural Statistics Service released the U.S. apple crop forecast for 2016 as being 10.4 billion pounds. This is the 4th largest crop since 2000 and 4 percent above the 2015 crop. The pear crop is predicted to be 5 percent below the 2015 drop due mostly to the removal of acreage and the grape crop is up 2 percent from a year ago. This is the time of year to attend to vole control. We have noticed a number of vole tunnels in our Lexington orchard already. Vole populations have the potential to build rapidly and after a heavy frost, tree rootstock bark begins to look pretty good to them (Figure 1). Apple trees are the most susceptible to vole damage, but voles also feed on other fruit tree types as well as occasionally blueberries Inside this Issue: Fruit Crop News...............................1 Upcoming Meetings............................ 2 2016 Fruit & Nut Crop Summary.................2 2017 Fruit & Vegetable Conference Meeting Outline............................ 4 Attention Fruit Growers - Has Spotted Wing Drosophila impacted you?.....................7 Phomopsis Twig Blight & Stem Canker of Blueberry. 8 2017 Fruit & Vegetable Conference Registration Form...................................... 9 Receiving Fruit Facts on the Internet............ 10 Figure 2. Vole damage to a young apple tree. and brambles. Vole damage may kill the plant (Figure 2), so it is important to watch your populations. The 2016 Midwest Fruit Pest Management Guide https://ag.purdue. edu/hla/hort/pages/sfg_sprayguide.aspx discusses commercial tree fruit control options on page 66. It is still not to early/late to apply a fungicide spray for peach leaf curl. This spray needs to be applied before peach buds begin to expand in the winter to be effective. Fungicides available are Bravo Weather Stick (other formulations and generics are also available), Ferbam, Ziram, and fixed coppers. The fixed coppers may also reduce overwintering bacteria that cause bacterial canker and bacterial spot. If you have a problem getting pre-emergence herbicides down early enough in the spring because of a heavy work load and tree prunings in the way, you might consider putting herbicides down this fall. It is also time to winterize your sprayer and blow water out of drip irrigation lines. Matt in the U.K AG Weather Center indicates that the three-month long range winter weather outlook is in flux. The predicted La Nina development for the fall appears to be fading making predictions difficult. Thus the state has an equal chance of temperatures being above or below normal and the same is true for eastern, southern and far western Kentucky with respect to precipitation. Northern and north west Kentucky appear to have the potential for above normal precipitation. This will be the last Fruit Facts issue for 2016. HAPPY HOLIDAYS!

The winter was very mild and temperatures did not drop below 0 F. Early season warm temperatures advanced floral development up to three weeks earlier than normal. On the mornings of April 3 and 10 temperatures dropped below freezing in many areas causing some frost injury, which did not substantially reduce crops for most growers, but a few had severe peach and apple losses. 2 Monthly precipitation averages for 2016 were below normal for January, April, September and October. February, May, July and August monthly averages were 1.3, 0.6, 3.5 and 1.4 inches above normal respectively. Overall since January the state is 0.5 inches above normal in total rainfall up until November 1. It was a wet season until late August and difficult to keep pesticides on plants, but then turned very dry. Monthly temperature averages were above normal for all but January and May. March and October temperatures were about 5.6 and 5.8 F above normal respectively. Fruit matured slightly early or at a normal date. In western Kentucky, Princeton had 29 days at or above 90 F compared to 19 last year, while Bowling Green experienced 9 days at or above 90 F compared to 21 last year. In central Kentucky Lexington recorded 8 days at or above 90 F as compared to 1 in 2015. In Jackson there were 2 days at or above 90 F. Japanese beetle populations were considerably higher this year in some areas because of the wet season and previous wet years. Many growers had problems with green June beetle fruit feeding. The brown marmorated stink bug (BMSB) is continuing to move westward and becoming more of a problem particularly in eastern Kentucky, Louisville and the Lexington areas. Spotted wing drosophila (SWD) was first trapped this year on May 19th about a week earlier than last year in Princeton, KY and confirmed across the state in all traps by July 1. Despite the early trap catch, SWD did not become a problem until mid-july as in the past two seasons. Fruit sales were very good for most growers. Apples Most Kentucky growers had full crops, but several growers experienced light to serious frost losses in April. Rainy conditions during pollination caused some fruit size reduction. Thinning was difficult because of persistent rainfall. Fruit color was less than average due to higher temperatures. High levels of cedar apple rust were observed on leaves and fruit where fungicide sprays were not maintained. Fire blight infection levels were high throughout the apple bloom period and resistance to Streptomycin was confirmed in one orchard. Frequent, heavy summer rains increased fruit rots, especially among early ripening varieties and those with extended spray programs where spray residue was washed off the fruit, leading to further potential reduction in crop. Frogeye leaf spot, Sooty blotch and fly speck and bitter rot, were very common. Oriental fruit moth remains a serious problem in some central Kentucky orchards. Codling moth levels fluctuated substantially between orchards. Pears European pears produced from 0 to a 50% crop while
Asian pears had a 5-100% crop depending on location. Fire blight inoculation levels were low because of cooler temperatures during bloom, but shoot infection levels were serious for some growers. Codling moth was at normal levels. BMSB damage levels were severe on Asian pears where this pest is established. Peaches & Plums The peach crop was excellent with the exception of a few isolated freeze incidents eliminating crops. In contrast to the previous season when cold winter temperatures and spring frosts severely reduced or eliminated the crop across much of the region, crop set was almost uniformly excessive. Vigorous crop thinning was necessary, which despite this activity was often still not enough to prevent an over-cropping situation. Several growers reported that it appeared that every flower developed into a fruit, that June drop did not seem to occur, and that they could not thin enough. Subsequently, harvested fruit size was smaller than expected. Frequent rains during ripening diluted the sugar and aromatic compounds in the harvested fruit, resulting in soft textures and watery flavor. Peach leaf curl levels were moderate. Bacterial spot and brown rot levels were high. The European plum crop was very variable, some growers had full crops while others had little or no crop. Pawpaws Pawpaws had between a 0 and 60% crop because of late spring frost. hybrid grapes produced 80% of a full crop. Vinifera grapes that survived the February 2014 extreme low temperature event are being retrained or growers have replaced them with hybrid cultivars. Most growers have had serious black rot, downy mildew, and or powdery mildew problems. Late season bunch rot, sour rot and botrytis were a problem, but overall fruit quality has been decent, particularly since dry conditions predominated in late August and September. Some vineyards experienced elevated bird pressure, especially on early ripening cultivars, possibly due to being caught off guard by the earlier than expected onset of ripening. Green June beetle populations and Japanese beetle populations were high in many vineyards. Grape root borer populations in vineyards above four years of age are on the increase. Blueberries Highbush and Southern highbush blueberries produced full crops. Mild weather during flowering provided excellent conditions for a high rate of flower pollination and subsequent fruit set. Berry size was good with leaf diseases and fruit rots being relatively minor. Loss from bird damage was spotty, with some areas experiencing higher pressure than others. Generally, where prevention was initiated too late or on later ripening cultivars. Phytophthora root rot was a severe problem with this spring s excessive rainfall. SWD does not seem to be much of a problem with blueberries. Strawberries Matted row strawberries produced about 75-100% crop due to frost and fruit rots, while plasticulture strawberries produced a 90% crop due to wet weather during harvest. Elevated temperatures early in the spring advanced bloom and some plasticulture fields experienced misshapen fruit from poor pollination or frost injury during a cool period in early to mid-april. The farm-toschool marketing program was a good one for plasticulture growers. SWD was found in a few strawberries at the very end of the season in southern Kentucky. Brambles Thorny and thornless blackberries produced full crops. Green June beetle and Japanese beetle feeding were significant. SWD was a problem in semi erect and primocane fruiting blackberries. The spring raspberry crop was normal. Fall bearing raspberries also produced mostly full crops, but dry weather and SWD were a serious late season problem. Systemic orange rust and Rosette were at normal levels. Grapes The 2016 harvest was reduced by spring frost and excessive rain and disease. American and interspecific 3 Nut Crops Nut crop production was mainly affected by wet spring weather. Since these crops are wind pollinated, rain reduced pollination. Thus, crops varied considerably from one area of the state to another. The wet weather also contributed to disease pressure, particularly Anthracnose which caused severe leaf drop in susceptible black walnut trees and scab which infected nut shucks and reduced nut fill in less resistant pecans.

If you grow fruit in Kentucky, we would like to know if you have been impacted by the spotted wing drosophila (SWD). We would also like to know if you used the Facebook page SWDinKY or if you used traps to monitor for SWD. To collect this information we have created a short survey. It is only 8 questions and should take 5 minutes or less to complete. Your responses are anonymous. No information about you or information from your computer will be collected. If you grow fruit in Kentucky, please take the survey now at https://uky.az1.qualtrics.com/ SE/?SID=SV_9uGz6qsIFS9OqHz The survey results will be used for reports and to improve SWD programs. If you have questions concerning this survey contact rbessin@uky.edu or plucas@uky.edu. Survey will be available till December 31.
Phomopsis Twig Blight & Stem Canker of Blueberry By Kim Leonberger, Extension Associate and Nicole Ward Gauthier, Extension Specialist Phomopsis twig blight and stem canker is becoming more common in Kentucky blueberry. Stressed plants are more susceptible to this disease, and reports are often associated with fields that have a history of Phytophthora root rot or severe abiotic disorder such as high ph. Phomopsis Disease Facts Symptoms first appear in spring as blighted twigs that result in flower bud loss (Figure 5). Necrotic, reddish-brown lesions may develop around blighted areas and spread downward. Wilting and flagging is observed as stems die (Figure 6). Girdling cankers can often be observed lower on stems. Leaf spots can also occur on foliage, and fruit may ripen prematurely or rot. Disease is favored by warm, moist periods. Plants damaged by freezing temperatures or stressed by poor planting sites are more susceptible to disease. Caused by the fungus Phomopsis vaccinii. The pathogen survives winter in dead or infected twigs. Prune out infected twigs by cutting a minimum of 6 inches below infected tissue. Discard cuttings; never leave them in the field. Avoid planting sites prone to frosts. Maintain plant health with proper fertilization, irrigation, and weed management. Avoid wounding stems. Fungicides may be applied preventatively (before infection) beginning at bud break and continuing through full bloom for plantings with high infection risk. Homeowners may use fungicides that contain the active ingredients captan or propiconazole. Contact a county Extension agent for more information on fungicide use. Fungicides do not cure Phomopsis tip blight.
