2019 MSHS Summer Tour Tour organized by Chris Walsh, Kathy Hunt & Susan Barnes of the University of Maryland

If you missed the 2019 Summer Tour on July 10, you missed a day of fun, education, and camaraderie. Though hot, the erratic summer weather cooperated and the participants enjoyed bright blue skies. We started our day with three lectures held at the Virginia Tech Alson H. Smith Jr. Agricultural and Research Extension Center. Over coffee, bagels, and fruit (thanks to Page Hargett of Farm Credit, again!), we listened to Chris Bergh, Professor of Entomology, give an update on the brown marmorated stink bug (Halyomorpha halys) population and biocontrol. While local populations have declined, other parts of the country still see heavy predation by BMSB in orchards. Dr. Bergh and his team worked with the parasitoid, Trissolcus japonicus in both lab and field trials. T. japonicus lays its eggs in the eggs of the BMSB preventing hatch of the pest. Of particular interest was the field work done in stands of tree of heaven (Ailanthus altissima) determining the canopy range of both BMSB and T. japonicus activity.

Keith Yoder, Emeritus Professor of Plant Pathology, brought us up to date on his work looking at the association of Tomato Ringspot Virus (ToRSV) and the incidence of incompatibility between Geneva root stocks and various scion wood. His trials are planted in non-fumigated soils where the dagger nematode (Xiphinema americanum) is known to exist. Populations of ToRSV are believed to survive in weeds such as dandelion (Taraxacum spp.) and are vectored by the dagger nematode into the susceptible rootstock, resulting in damaging necrosis. We then adjourned to the top of the hill and listened to Tremain Hatch, Viticulture Research Technician, speak on the progress of their grape trials. They have been working with the technique of leaf pulling to enhance the amount of sun exposure to the fruit. This increased sunlight improves red color development, concentrates sugar production, and prevents ripe rots. In another section of vines, plastic was used as a rain shield and yet still allow for sun exposure. Again this is in an effort to minimize ripe rot. Woodbine Orchards was our next stop. There we were treated to a wagon tour of the orchards hosted by Carol Swanson and Mike Smith, orchard manager. Of particular interest was the incidence of tree failure due to graft incompatibility. Chris Walsh and Bill Mackintosh (Macintosh Fruit Farm) spoke on the general brittleness of Geneva rootstocks and the incidence of loss simply due to wind. This incompatibility of scions to Geneva rootstock was found to vary depending on the variety used. One tree in particular was examined. This was a Crips Pink grafted on to a G41 root stock. From the picture it can be noted only a small portion of living wood remained. As we toured the acres of fruit crops the subject of deer management was discussed. Currently Woodbine Orchards is using a variety of detergents, soaps and/or Milorganite hung in bags at the head of each row.

2019 MSHS Summer Tour Highlights continued from page 2 Their conclusion was that the only effective deer repellent seemed to be proximity to a highway. Box lunches were served at West Oaks Farm Market in an outdoor pavilion situated at the crest of a rise. Though the day was warm, the positioning of the structure allowed for natural ventilation and beautiful views of the hills and fields. Levi & Joe Snapp spoke a bit about the pavilion being part of a complex of newer structures they have built on this Century Farm. West Oaks Farm has been in the same family for ten generations and dates back to 1752! Though they have an impressive history, this generation has embraced diversity and highlights not only the spacious outdoor pavilion, but also a large indoor wedding/meeting venue and an impressive farm market. The market features a wide range of local products including meats, produce, cider, wine, and alpaca fiber products. They bake on site, as well as have grilling and cooking facilities providing a wide selection of menu options.

Levi & Joe also talked about their success with pick-your-own strawberries and their plans for PYO apples. We had gathered next to a beautiful young orchard that should be ready to harvest in the next growing season or so. There are acres of mature apple trees that are harvested for their two farm markets as well as for wholesale. PYO pumpkins will complete the season for what is evolving as a destination family venue. There are also plans for a sixacre corn maze that Levi estimates will take a customer over an hour to complete. With this farm moving to more PYO produce, the challenges of dealing with in field marketing and cashier placement issues were discussed. The concept of a pre-paid box was favored as it would reduce the need for as many in-field cashiers and better control over product shrinkage. Some of the group then ventured on to Arterra Wines in Delaplane, VA. A tour of the vineyard with wine tasting after was offered by owner Jason Murray. Arterra (Art of the Land) offers niche market wines, fermented using natural yeast in small batches. No chemicals are used to manipulate the natural flavors of the wines produced. During the tour of the vineyard, Jason described the soils in his two growing areas and how growing for a nonchemical fermentation challenges the grower. For instance, no fungicide sprays are used 4-6 weeks before harvest. Fungicide residue would kill the naturally occurring yeasts.

The Tannat was described by connoisseurs to be both a wine that is favored by the growing conditions of the area and one that Arterra does exceptionally well. The attending fruit growers were pleased to see an offering of two fruit wines. This provided a sweet ending to a very informative and enjoyable day.

Renewing Your MSHS Dues If you are not planning to attend the Mid-Atlantic Fruit and Vegetable Convention this year, please consider renewing your Maryland State Horticultural Society (MSHS) membership for 2020. Dues that are collected are used to support educational programs, and much needed research for many of the production problems that commercial growers face. As funds continued to be cut at our land grant universities, the local horticultural societies have been able to fund research projects. These funds are then used for matching grants. Because they are grower-funded, they are very effective levers for obtaining additional funds. Like it or not, research these days requires outside funding, and we need to step it up if we’re going to get meaningful results


when we need them. Membership dues for 2020 is $50.

balance throughout ripening on-the-tree and postharvest storage. In my Post-Doctoral position, also at UC Davis, I worked on the identification of breeding targets for texture and flavor improvement in a melon breeding program by combining sensory, physiological and transcriptomic studies. Additionally, during my years at UC Davis I participated in several extension activities as well as in an entrepreneurial program, working collaboratively and innovatively towards the improvement of fruit quality and shelf-life capacity. I am originally from Chile, where I received my B.S. and M.S degree in Agricultural Sciences from the University of Chile, with focus on Fruit Postharvest Physiology/Biology. Besides, I have four years of experience working at the interface between academia and industry, targeting the improvement of fruit quality/nutritional value and shelf -life capacity from a cross-functional perspective. In these positions I had the opportunity to work with and build strong cooperative relationships with the fruit production sector in Chile, engaging in several extension activities. A fun fact: on Chilean television I hosted the TV show “Caring for our Field”, aiming to help growers improve the production, management, storage and handling practices of fruit horticultural crops. When I am not in my office or laboratory at the Department of Plant Science and Landscape Architecture or in the field, I like to enjoy the outdoors. You can find me discovering new hiking trails or heading towards the ocean. I enjoy playing tennis and traveling, and I am a seafood fan!

My name is Macarena Farcuh, and I just recently joined (10/2019) the Department of Plant Science and Landscape Architecture at the University of Maryland as an Assistant professor in Horticulture, with a Research and Extension appointment. I am really excited to have joined the team and I am looking forward to contributing with my background to improving the production, quality and postharvest marketability of the fruits produced by growers in Maryland, in the Mid-Atlantic Region and in the nation! The aim of my program is to decrease fruit loss/waste, meet consumers’ expectations, and enhance fruit consumption. This will contribute to environmental and economic sustainability, as well as to promote health and well-being.

I am looking forward to meeting and working with all of you!

This fall PBS Farm and Harvest program were filming a show on apples. The program focuses on apple production and breeding at the University of Maryland. They filmed at Keedysville where they met with Chris Walsh and talked about his new apple, CP101 (‘Antietam Blush’). Right after that, they visited the lab in the Plant Sciences Building in College Park to learn about apple maturity and fruit quality. We expect this program to air in early 2020. Watch for it!


The Strawberry Advisory System in the Mid-Atlantic: a Final Update Mengjun Hu, Ph.D., Department of Plant Science and Landscape Architecture, University of Maryland, College Park, MD

As many of you are aware, the Strawberry Advisory System (StAS), a disease forecasting system, is now available to support regional strawberry production. This project, funded through USDA-NIFA and Horticultural Society of Maryland, was initiated by former UMD small fruit pathologist Dr. Cassandra Swett. The StAS, originated at University of Florida (led by Dr. Natalia Peres), utilizes site-specific weather stations to monitor leaf wetness and temperature to predict infection risks for Botrytis fruit rot (BFR) and anthracnose fruit rot (AFR) in real-time based on the disease models developed previously (Bulger et al. 1987; Wilson et al. 1990). The beauty of StAS is that users can virtualize the real-time infection risk at AgroClimate (http://cloud.agroclimate.org/tools/sas/dashboard/disease) or through the smartphone app SAS (Fig. 1). Free subscriptions of email and/or textmessage are also available to get timely alerts for fungicide applications when there is medium or high risk of AFR or BFR infection. Fig.1. The Strawberry Advisory System Webpage With the capability of predicting disease infection, it can improve timing of fungicide applications to avoid unnecessary sprays. According to 39 field trials conducted mainly in Florida from 2009 to 2014, no significant differences were found in BFR/AFR incidences, yield and number of marketable fruit between the StAS and calendar-based treatments in each trial. However, the number of fungicide applications was reduced by 50% on average when using the StAS compared with the calendar-based spray schedule (Cordova et al. 2017). Trial data. From 2017 to 2019, field trials have been conducted in Maryland and Virginia on both matted-row and plasticulture strawberries to validate the efficacy of the StAS in the Mid-Atlantic region. Overall, the performance of the StAS is acceptable. Marketable berries, disease incidence in the trials were largely comparable between the StAS and calendar

-based spray schedule (Tables 1-3), despite that the StAS seemed to be associated with slightly higher incidence of AFR or BFR. However, unacceptable results were also noted in the trials conducted in VA during 2016-2017 season (Table 4), presumably due to fungicides not sprayed in time. Unlike FL, many fields in the Mid-Atlantic that have received more than an inch of rain are often too soft and wet to spray within 48 hours, a timeframe required by the StAS. In order to address this issue in the following season, fungicide sprays were made just before a likely rain event that may result in more than 1-inch of rain, if the field had not been treated in the last 5 days. As a result, no significant difference in BFR and AFR incidences was observed between the StAS and calendarbased sprays in the 2017-18 season (Table 4).

BFR and AFR stand for Botrytis fruit rot and anthracnose fruit rot, respectively. Row-cover situation. In addition to the difference in soil condition noted above, the efficacy of StAS may be challenged by difference in cultural practices. In areas outside FL and CA, floating row covers are used to protect berries from frost damage during winter and spring, or to accumulate growing degree-days during fall. The StAS uses on-farm weather stations for model input (i.e. temperature and leaf wetness), which are not capable of monitoring environmental variables under row covers. Whether the deployment of the rowcover during fall or early spring would result in disease infection is unknown.

Available StAS weather stations in the Mid-Atlantic. A total of seven stations were installed in Maryland and Virginia. Among them, two are located in Pungo area in VA and five are located in Fredrick, Montgomery, Charles, Carroll, and Queen Anne's Counties of MD. Based on our observations, disease risk categories (i.e. low, medium and high) between weather stations in western MD were largely consistent over the course of two years, which sometimes are different from Southern MD or the Shore. However, difference in disease risk category did occur occasionally between two StAS locations nearby. Cost and Maintenance. The cost of having a standard StAS weather station (METOS) manufactured by Pessl instruments is about $3,000. An annual fee of $100 is charged to access weather data such as wind, precipitation, temperature, relative humidity etc., depending on the sensors equipped with the station. The station is solar-panel supported and all data is cloud-based and viewable remotely and constantly. The sensors and solar panel on the station are expected to send back to the manufacturer for maintenance every three to five years. The total annual cost, excluding the purchase of the station, is expected to be $200 to $300. Conclusions. Data from some trials indicated that the StAS may need to be more sensitive especially for highly susceptible cultivars. Recent trials conducted in Iowa also suggested that the StAS might underestimate AFR risk under high disease pressure (Zhang et al. 2019). Overall, we think that the StAS can be a valuable tool to support Mid-Atlantic growers, but fungicides need to be sprayed in time (within 48 hrs. after the warning). Further studies are needed to understand the impact of row-cover on the plant microclimates and disease infection. Reference: Bulger, M. A., Ellis, M. A., and Madden, L. V. 1987.

Carol University of Maryland—AGNR-PSLA The Produce Safety Rule (PSR) section of the U.S. Food Safety Modernization Act (FSMA) is aimed at reducing the risk of human exposure to microbial pathogens when fresh fruits and vegetables are consumed raw. Most all fruits and vegetables that are generally eaten raw are covered. That will include most tree fruit crops (excluding sour cherries and figs). Find the full list of covered produce here: https:// producesafetyalliance.cornell.edu/sites/ producesafetyalliance.cornell.edu/files/shared/ documents/FSMA-Regulatory-Table.pdf The Produce Safety Rule is a mandatory federal regulation that is implemented based on the amount of produce sold and to whom.


You are exempt if you sold less than an average of $26,999 in covered and non-covered produce over the previous three-year period.


You are required to comply to the rule if you sold over an average of $539,982 in produce sales per year in the last three-year period.


It is the middle area – the qualified exempt status that gets complicated. A QE producer will meet the following criteria:


your average total food* sales were less than $539,982.


A lot will depend on what percentage of your food* sales were to “qualified end users”. So who is a qualified end user? 1. Your PYO and farm market customers and 2. restaurants and retail food stores in the same state and less than 275 miles away and they sell directly to the consumer.


More than half (50.1%) of the value of the total food* sold went to the aforementioned qualified end users.

*For this calculation grains, animal feeds, poultry, livestock, etc. are included If you find that you fall into either the qualified exempt or required compliance categories, what do you do? The first step would be to attend a Produce Safety Alliance training on the PSR. That training will outline the compliance requirements. Though lengthy, the PSR requirements are fairly common sense standards and procedures that you are probably already implementing on your farm and are very similar to GAP (Good Agricultural Practices) certification requirements. These are the dates and locations of the 2019-2020 season. December 4, 2019 – Princess Anne January 24, 2020 – Howard County February 6, 2020 – Montgomery County March 3, 2020 – Garrett County Use Eventbrite to enroll: https://www.eventbrite.com/o/university-of-maryland-extension-5296025477 You will need at least one person on your farm who has taken the training. It is very important that the PSA trained person be in a position to update procedures and train workers in the PSR standards. In Maryland we are privileged to have the Maryland Department of Agriculture overseeing PSR compliance. Inspections of the larger producers have already started and many farms are electing to have an On Farm Readiness Review (OFRR) before an inspection. The OFRR brings three specialists to your farm: someone from MDA, someone from your local extension office, and a food safety educator from the University of Maryland. This team will go over the compliance requirements with you and look specifically at your farm’s unique situation. Even the FDA is looking at this first year as a time of education not retribution. I have attended many OFRR’s this year and the farmer feedback is that they are very helpful and give real, reasonable application to what can be a very confusing set of laws. The goal is to develop a food safety culture on your farm and with your workers to help keep your customers safe. Contact Kathy Hunt at 301.405.4372, Carol Allen (callen12@umd.edu) or Angela Ferelli, PhD (angfer@umd.edu) for more information and to arrange a one-on-one consultation to help you get ready for an OFRR.

Does it Pay to Graft Tomatoes for Increased Yields When There Are No Soil Disease Problems? Jerry Brust, IPM Vegetable Specialist Tomatoes are grafted by joining the top part of one plant (the scion) to the root system of another plant (the rootstock). The resulting plant is usually more vigorous and productive. Many studies have been conducted over the last 10 years that show the benefits of using grafting for soil disease control in tomato production, but there is not much research that examines the influence of rootstocks in no-disease field tomato production systems. In general, vegetable grafting can increase yield by improving crop tolerance to abiotic stresses because of the plant’s ability to increase water and nutrient uptake via a more vigorous rootstock. I looked at what would be the benefit, if any, of grafting four different tomato varieties into a field that had not had any vegetables in it for at least 4 years and had no history of soil disease problems. The varieties were: Red Deuce, Red Mountain, Big Beef and Mt. Fresh+ onto the rootstock of Maxifort. Methods: Grafting treatments consisted of two combinations: a scion/rootstock graft and a non-grafted control using the same variety. Approximately seven weeks after grafting, all grafted and non-grafted seedlings were transplanted into the field on 3rd May, 2019. Before transplanting the field was fertilized and black plastic mulch with drip irrigation was laid forming 8 rows 100 ft long. There were three replications of 10 tomatoes of each variety grafted and 10 plants nongrafted spaced 2 ft apart within a row. Eight harvests took place starting on July 9 and continuing on July 12, 15, 18, 23, 29 and Aug. 1 and 8. Yields were subjected to a 2-factor ANOVA looking at variety (4) by grafted or not (2) and means were separated using Tukey HSD test. ANOVAs with p values equal to or less than 0.05 were considered significant as were mean separation tests. Leaf tissue samples were taken at first flower bud and every two weeks throughout the study. Fruit harvests were conducted two-three times per week and separated into marketable and non-marketable fruit. Non -marketable fruit categories consisted of yellow shoulders, uneven ripening, cat-facing, blossom end rot, fruit cracking and ‘other’. Fruit number and weight were recorded. Results: Overall the total marketable fruit weight for grafted plants (mean of 15.2 lbs/plant) had significantly greater yields compared with non-grafted plants (13.7 lbs/plant). All varieties that were grafted had on average 11% more marketable fruit compared with their non-grafted variety. Early yields (9 and 12 of July) showed no differences between grafted and non-grafted plants for any of the varieties, although the variety Red Mt. significantly out yielded Big Beef and Mt Fresh+ by almost 93%. For the main harvests (15-29 of July) grafted plants were significantly greater in marketable yields (13.3 lbs/plants) compared with non-grafted plants (11.8 lbs/plant). There was a significant difference between three of the varieties (overall mean of 12.9 lbs/plant) vs. Mt. Fresh+ (11.3 lbs/plant). For the later harvests (1 and 8 of August) yields for grafted plants were significantly greater (1.67 lbs/plant) vs non -grafted plants (1.05 lbs/plant). For this harvest period Red Deuce had significantly greater yields (1.86 lbs/plant) than Big Beef (0.95 lbs/plant) or Mt. Fresh+ (1.30lbs/plant).

Figure 1. Excellent fruit set and quality of tomatoes in July

had a mean of 22.6% unmarketable fruit. There were no significant differences in unmarketable fruit between grafted and non-grafted plants or among any of the varieties. Conclusions: I was encouraged when I saw that the grafted plants out yielded the non-grafted plants by a small but significantly consistent amount. However, when I applied some basic economics to the results looking at the difference in costs of the grafted vs non-grafted transplants and the return on yield I found I lost $0.21 per grafted plant vs. a non-grafted plant. If you multiplied that by 5,000 plants/A that would be an estimated loss of around $1050/A between using grafted vs. non-grafted plants in this particular trial for this year. More trials will be needed in the coming years to see if this trend holds or if using grafted plants in non-stressed fields can more than pay for itself. Overall a couple of things surprised me. The first was that Mt. Fresh+ did not do as well as the other varieties, this variety has always performed well for me in my studies and for some reason this year it did not. The second thing was the quality of the tomato fruit during the main harvest period, basically most of July, was outstanding. Often times in the past my unmarketable fruit reached 25-35% of my harvested fruit in July, but this year the mean was only around 11% - amazingly low and using grafted plants did not reduce the unmarketable fruit significantly compared with non-grafted plants. Part of the reason for this I think was the great reduction in rainfall that led to low disease incidence in the field, but also to the excellent fruit set in both grafted and non-grafted plants (fig. 1). Grafting seems to help with the yields or quality of the fruit when plants are under some kind of stress such as flooding, high salts, soil diseases, soil nematodes, etc. If environmental conditions are good the grafting does not seem to help as much, as shown in this study.

The all-important nutrient potassium (K) was 22.2% greater in grafted plants vs. non-grafted plants in July, but that was about the only difference between grafted and non-grafted plants for nutrient levels. Early harvests had a mean of 5.2% unmarketable fruit while main harvests had a mean of 11.3% unmarketable fruit and the final harvests


Paraquat Dichloride Training for Certified Applicators Source: United States Environmental Protection Agency (EPA), https://www.epa.gov/pesticide-worker-safety/paraquat-dichloride-training-certified-applicators

As required by EPA’s Paraquat Dichloride Human Health Mitigation Decision and amended paraquat dichloride (a.k.a. paraquat) product labels, certified applicators must successfully complete an EPA-approved training program before mixing, loading, and/or applying paraquat. The training provides important information about paraquat’s toxicity, new label requirements and restrictions, and the consequences of misuse. To access the EPA approved training module through eXtension Online Campus go to https://campus.extension.org/course/view.php?id=1660. This training was developed by paraquat manufacturers as part of EPA’s 2016 risk mitigation requirements and has been approved by EPA. Below are frequent questions about the paraquat dichloride training. Why are there additional training requirements to use paraquat? Answer: Since 2000, there have been 17 deaths – three involving children – caused by accidental ingestion of paraquat. These cases have resulted from the pesticide being illegally transferred to beverage containers and later mistaken for a drink and consumed. A single sip can be fatal. In addition to the deaths by accidental ingestion, since 2000 there have been three deaths and many severe injuries caused by the pesticide getting onto the skin or into the eyes of those working with the herbicide. To prevent these tragedies, EPA is requiring this special training for certified applicators who use paraquat. One of the purposes of the paraquat training is to reinforce that paraquat must not be transferred to or stored in improper containers.

Who is required to take this training? Answer: Any person who intends to use paraquat must be a certified applicator and is required to take the training. “Use” includes pre-application activities involving mixing and loading the pesticide; applying the pesticide; and other pesticide-related activities, including, but not limited to, transporting or storing opened pesticide containers, cleaning equipment, and disposing of excess pesticides, spray mix, equipment wash waters, pesticide containers, and other paraquat-containing materials.

Who is permitted to use paraquat? Answer: The use of paraquat, which is a restricted use pesticide, is restricted to certified pesticide applicators only; noncertified persons working under the supervision of a certified applicator are prohibited from using paraquat, including mixing, loading, applying the pesticide, and other pesticide-related activities.

What are the training requirements for paraquat products? Answer: To use paraquat products, you must be a certified applicator. In addition, paraquat-specific training is required by new paraquat labels and must be completed prior to using products with the new labeling. All paraquat labels are expected to include a link to the training by Fall 2019. The training provides important information about paraquat’s toxicity, new label requirements and restrictions, and the consequences of misuse. The training must be retaken every three years. Although this training is a paraquat label requirement, a state may choose to approve it for continuing education. For state-specific requirements, contact your state lead pesticide agency. To find the contact information for your state lead pesticide agency, see the National Pesticide Information Center’s

webpage http://npic.orst.edu/reg/state_agencies.html on state pesticide regulatory agencies

How does the paraquat training module differ from the certified applicator training requirements? Answer: Pesticide applicators become certified by proving they are competent to apply or supervise the use of restricted use pesticides (RUPs), generally by examination. Many states approve courses that certified applicators can take to maintain their certification. The examinations and training courses pertain to a category or type of pesticide application (e.g., agricultural plant pest control, seed treatment, structural pest control). Conversely, the paraquat training module emphasizes the importance of handling paraquat safely because of its extreme toxicity. The training highlights product-specific restrictions, including that paraquat products bearing the new labeling can be handled by certified applicators only (i.e., paraquat can no longer be handled by those working under the supervision of a certified applicator). For more information related to the pesticide applicator certification, visit: How to Get Certified as a Pesticide Applicator at https://www.epa.gov/pesticide-worker-safety/how-getcertified-pesticide-applicator

One of the label requirements is to maintain a record of the completed training. How will certified applicators show proof that they completed the required training? Answer: Once the certified applicator successfully completes the training, a certificate will be automatically generated. Per the new labeling, applicators are required to retain certificates of training completion. In addition, paraquat registrants have arranged for the National Pesticide Safety Education Center (NPSEC) to retain certification records should the user, state regulators, or enforcement personnel need access.

Who is responsible if a certified applicator overlooks a label requirement, even if the paraquat-specific training covered that point? Answer: The intent of the training is to provide the user with the best possible understanding of paraquat product safety issues. Ultimately, it is the user’s responsibility to handle the product in strict accordance with the product labeling.

Are state personnel required to conduct the paraquat-specific training? Answer: No, state employees are not required to conduct this training. The training is available online for paraquat users to take at their convenience at www.usparaquattraining.com.

Are states or other entities permitted to develop alternate paraquat training materials? Answer: States or other entities may develop alternate training materials that comply with the 2016 mitigation decision. All paraquat handler training materials must be approved by EPA. For a discussion of the requirements for the training materials, refer to the 2016 Paraquat Dichloride Human Health Mitigation Decision by going to https://www.regulations.gov/contentStreamer? documentId=EPA-HQ-OPP-2011-0855-0115&contentType=pdf
