TNLA’s

Three Critical Components C

onsider the following: little pigs and gruff goats, French hens and cartoon ducks, blind mice and kittens. How about religion, government, ghosts and triangles? What could possibly link those things to the TNLA and this issue of Tennessee GreenTimes? The number three, that’s what!

Just as the Tennessee state flag has stars representing the three Grand Divisions of our State, our In the Garden article (starting on page 10) will introduce you our state botanical gardens. After you read this article, I am sure that you will want see for yourself just how brightly these three stars shine!

Just as a triangle has three sides, the TNLA has three key components as well: membership, leadership and partnership. As an organization, we value each and every member and encourage you to be active in the association. The TNLA board of directors recognizes our responsibility to the industry and, most importantly, to your best interest in every decision that we make. As an organization, we value our partnerships with all the educational and governmental entities that are vital to keeping Tennessee horticulture in a national leadership role. (Check out Dr. Nick on page 20!) We especially value the partnerships and relationships we have with our customers, and we encourage each of them to buy Tennessee!

I want to say a special thank you to Randall Walker for his long-time service on the board as Secretary-Treasurer. He has been steadfast in his duties and helped to keep our association strong. Speaking of dedication and loyalty, please join me in recognizing Louree Walker, our executive director, for her twenty years of continuous service to the TNLA. Remember those ghosts I alluded to? You may be thinking of Dickens’ ghosts of Christmas Past, Present and Future, but I was thinking about the Tennessee Green Industry Expo. Plan on visiting the trade show to see what’s happening now with the most up-to-date horticultural products and supplies. Prepare yourself and your organization for a profitable future by taking away some great insights from our educational program. Why, you can even celebrate the past by attending the TNLA Awards banquet as we recognize the best of 2013!

It has been my privilege to serve as president of the Tennessee Nursery and Landscape Association. I am especially appreciative of the work done before me

by Michael Kassees, and I am looking forward to the leadership of Matt Dawson in the coming year. We have exciting news to share and bold plans in place to grow our association.

I hope to see you in Nashville!

Sincerely,

Bill Seaton 2013 TNLA President

In the Garden

The UT Gardens…

One State Botanical Garden with Three Locations

By Patricia McDaniels, University of Tennessee Institute of Agriculture

The

story of Tennessee’s botanical garden has been 30 years in the making. In April 2013, the University of Tennessee Gardens’ statewide collection was designated as the state’s official botanical garden, but it was back in 1983 that faculty in the UT Institute of Agriculture first envisioned a teaching and research garden that would benefit horticulture students and the state’s nursery industry.

From that first vision, the idea grew and grew. Today, the UT Gardens’ statewide system includes three sites: the original UT Gardens in Knoxville; the UT Gardens in Jackson; and the recently dedicated Plateau Discovery Gardens, located in Crossville.

Together, they form the state botanical garden.

UT Gardens, Knoxville In 1983, ornamental horticulture and landscape design faculty knew that integrating nature and green spaces into daily life would be essential to the wellbeing of an ever-growing urban culture.

Since the first trial gardens were planted on the campus of the UT Institute of Agriculture in Knoxville, the UT Gardens have served the Institute’s promises to deliver research discoveries to industry and the public, to promote handson learning and to serve local communities.

UT Gardens, Jackson Located on the grounds of the UT West Tennessee AgResearch and Education Center, the UT Gardens in Jackson includes a kitchen garden, a low-maintenance fruit demonstration orchard, annual and perennial displays, an AllAmerican Selection display, an American Conifer Society reference garden and more. The site hosts the popular Summer Celebration Lawn and Garden Show. Scheduled for the second Thursday of July, the event attracts annually more than 2,000 gardening enthusiasts.

UT Plateau Discovery Gardens, Crossville This newest UT Gardens site, which is on the grounds of the UT Plateau AgResearch and Education Center, is truly an example of the volunteer spirit. Many of the plots were designed and built by local Master Gardener trainees. Master Gardener programs are managed by local UT Extension offices, and volunteers receive extensive horticultural training in exchange for providing that information to the public through a variety of service opportunities.

Some 2,100 Master Gardeners have provided more than 153,000 hours of service to Tennessee communities. (More information is online at http://mastergardener.tennessee.edu.)

Bottom: A mixed planting at UT Gardens in Jackson. (Photo by C. Reese, courtesy of UT Institute of Agriculture.)

A shared mission Although each site is unique — complete with its own variations in annual temperatures, topography and soil qualities — each shares the same mission to serve society and the nursery industry through fostering appreciation for and stewardship of cultivated plants through garden displays, educational programs and research trials.

Dr. Susan Hamilton, known to the state’s gardening community simply as Dr. Sue, directs the UT Gardens system, but she is assisted by associates and volunteers at each of the UT Gardens sites. James Newburn, Jason Reeves, Carol Reese and Gregg Upchurch are among the familiar UT Institute of Agriculture faculty contributing to the gardens statewide.

Multiple research and demonstration gardens are maintained at each site. The research plots test plant cultivars for suitability regarding the region’s growing conditions. Some 4,000 annuals, perennials, herbs, tropicals, trees, shrubs, vegetables and ornamental grasses are evaluated each year for growth vigor, bloom quality, climate tolerance or other characteristics.

Home gardeners and nursery, landscaping and retail businesses all benefit from learning the most successful cultivars for a given area.

The demonstration gardens at each site allow imaginations to bloom. Students — from kindergartners to college students to senior citizens — participate in a variety of outreach programs that cultivate an appreciation of the plant-growing arts and of managing outdoor spaces. In just the past year alone, more than 100,000 people visited a UT Gardens site or attended an educational event.

Feel free to visit!

Each of the UT Gardens sites is open to the public during daylight hours and free of charge to visit; however, some specially scheduled programs are fee-based and may temporarily restrict access to certain areas. Each of the UT Gardens sites also has a group of friends and volunteers who work behind the scenes to maintain and enhance the site’s plant collections. From Master Gardeners to kindergarteners, there’s room for everyone to learn and contribute.

Spotted Wing Drosophila and the Green Industry

By Karla Addesso, Research Assistant Professor of Entomology, TSU Otis L. Floyd Nursery Research Center, McMinnville, TN

14

tennessee greentimes Winter 2013

Photo 1.

S

potted wing drosophila (SWD) is a vinegar fly native to Asia. Like its North American relatives, SWD is attracted by the smell of fermenting fruit.

Unlike its relatives, SWD does not have to wait until fruit is rotting to attack. The fly can lay its eggs in fruit as it begins to ripen on the plant, making this species one of the few Drosophila of agricultural concern.

About SWD Spotted wing drosophila is small (2–3 mm long), with red eyes and a yellow body with black, contiguous stripes across the abdomen. Males have a distinct black spot on the front tip of their wings (Photo 1a).

Females do not have a wing spot (Photo 1b), but they can be recognized by their dark, serrated egg-laying organ, which allows them to cut the skin of ripening fruit (Photo 1b insert). These distinct characteristics will not be seen in other, native vinegar flies.

Spotted wing drosophila has a wide host range consisting of cultivated small fruits and berries, ornamental plants and wild hosts (see Table 1). Most of the known hosts are members of the Rosaceae family, but plants in other families are also readily attacked. Knowledge of SWD’s host preference for berry-producing ornamentals is limited, but the list is bound to expand with further investigations.

Spotted wing drosophila was first detected in California in 2008. In 2009, it spread north to British Columbia and was reported in Florida for the first time. In 2010, the fly was caught in Michigan, Mississippi, North and South Carolina, Utah and Wisconsin and continued to spread throughout the United States. As of October 2013, the only states that have not reported the presence of SWD are Nevada, Arizona, New Mexico and Alaska.

Spotted wing drosophila was first reported in Tennessee in 2010 from an infested Photo 1. Spotted wing drosophila: (a) male and (b) female. Insert photo: the female’s serrated egg-laying organ.

blueberry field in Unicoi County. The first capture of SWD in Middle Tennessee was at the Tennessee State University’s Nursery Research Center in McMinnville on December 14, 2012. There have been positive IDs of SWD in counties throughout the state, and given the fly’s documented presence in all states surrounding Tennessee, SWD is likely to achieve a statewide distribution.

Spotted wing drosophila is fairly cold tolerant and is active at temperatures above 50°F. Average high temperatures during December, January and February in Middle Tennessee are at or above this activity threshold, making it possible for the fly to be active in some parts of the state year-round.

Monitoring in Middle Tennessee We initiated a survey for SWD in the fivecounty nursery production region of Middle Tennessee in June 2013 in order to determine whether the fly was established in the landscape. Simple traps constructed of 32 oz. deli containers and marked with yellow or red bands (Photo 2) were placed along roadsides in Warren, DeKalb, Coffee, Franklin and Grundy counties at three different locations. Traps were baited with an active yeast and sugar-water mixture, and flies were collected from the traps for eight weeks.

Spotted wing drosophila flies were captured at every trap location in all five counties at least once. Trap captures increased throughout the study and dramatically during the final two weeks of monitoring, coincident with wild blackberry ripening (Photo 3 and Figure 1). Flies were caught at trap locations with hosts present and at locations where no known hosts were observed. The color of the trap did not matter.

A total of 6,713 SWD were captured over an 8-week period.

Concerns to industry Host preferences for ornamental fruits have not been conducted, but the wide range of hosts attacked suggest that any berry with a thin skin is potentially susceptible. At the Nursery Research Center, the flies built up a large population on wild blackberry bordering the grounds, moved into a kousa

Pest in the Spotlight

patch on the property and subsequently infested neighboring flowering dogwoods (which had not been previously identified as a host of SWD). The observed buildup and host-shifting by the fly may suggest that non-preferred hosts will be attacked following population buildup on nearby preferred hosts.

No studies on seed viability of dogwoods or other ornamentals following infestation of SWD have been conducted to date.

Infestations of fruits by other insects have been documented to negatively affect seed formation and vigor, resulting in poor germination. Infestation by SWD can also cause premature abscission of fruit. Taken together, these effects may result in decreased quantity and quality of seed for production.

The aesthetic quality of berry-producing ornamentals may also be impacted by infestation. Spotted wing drosophila attacks fruit just as it begins to ripen, causing the fruit to discolor and shrivel on the plant and abscise. Plants with showy berries (such as hollies) may be affected. In addition, without routine insecticide sprays, this pest will also reduce the benefit of ornamentals grown for edible fruits.

Interstate movement of flies by nursery stock is of minimal concern due to the widespread establishment of the pest across the United States. There are presently no international quarantine restrictions for nursery stock with regards to SWD.

Actions for producers and landscape professionals Due to the amount of uncertainty surrounding SWD’s impact on the green industries, the most important thing that growers and landscape professionals can do is to be vigilant. Table 1 is not a definitive list of plants attacked by SWD; other plants are likely to produce fruit suitable for SWD. If problems (such as premature fruit drop or shriveled and deformed fruit) arise with a berry-producing crop, SWD may be the culprit. If you suspect SWD in a crop, collect fallen or damaged fruit and hold them in a Tupperware container for two weeks to see if SWD flies emerge. You may need to take samples to your local county Extension agent for identification.

Pest in the Spotlight

Current recommendations for SWD in commercial fruit production include, at minimum, removal of fallen fruit and weekly application of pesticides once fruit begin to ripen, continuing until harvest. Such a management plan is likely to be impractical for ornamentals, but it may be necessary to protect seed on plants used for propagation or to maintain the aesthetic quality of certain plants until sale.

The following active ingredients have been shown to be effective against SWD in fruits: bifenthrin, fenpropathrin, cypermethrin, spinetoram, spinosad, phosmet. Malathion, acetamiprid, pyrethrum and azadirachtin are effective to a lesser extent. Check pesticide labels for approved use on target nursery and landscape plants.

Spotted wing drosophila, like so many invasive species, is here to stay. Awareness of its presence and potential effects is key to minimizing its impacts on the green industry. C
