inter is upon us, and that means winding down our fall planting and digging and gearing up for what promises to be an especially busy spring season next year. Just like the changing of the seasons, it is also time for new leadership to ascend within the TNLA, as my term as president is nearing its end. This will be my final letter within the GreenTimes quarterly magazine, and as such I would like to say a special thanks to Mr. Kim Holden for his contributions to the TNLA. This concludes a five-year term on the board of directors for Kim, and he has put in countless hours of his time to help keep the association moving forward and to make our tradeshows and other endeavors successful.

Looking ahead, the new president of the TNLA will be Justin Stelter. As you get to know him, I think you will be impressed with his vision for the organization, and we will all benefit from what I’m sure will be great ideas and leadership moving forward.

Recapping this year’s Tennessee Green Industry Expo, I have heard many great reviews regarding sales and networking among both exhibitors and attendees.

Once again, the show was held in conjunction with the MTNA at the McMinnville Civic Center. We had a great turnout at all of our events, and from everyone I’ve talked to, it was once again a productive endeavor.

We are very excited about next year’s tradeshow, which will be held at the Wilson County Expo Center in Lebanon. I think I can speak for our association as well as MTNA when I say we are very much looking forward to all the possibilities with that show and the events surrounding it, and I’m confident that our tradeshow committee will once again put together a great event.

In closing, I would like to say it is an honor to have served on the board for the TNLA. I have met many great people within the association that I do not believe I would have had the chance to meet otherwise. I hope to continue to be a resource for you in the future, and know that I am appreciative of the trust to have served you for these years.

Downy Mildew

Management

on Roses

By Fulya Baysal-Gurel, Ph.D., Assistant Professor of Plant Pathology,

Otis Floyd Nursery Research Center, Tennessee State University

R

ose downy mildew, which is caused by the oomycete Peronospora sparsa, is one of the most destructive diseases of rose plants, and it attacks all types of roses in greenhouse, nursery and landscape settings. Although rose downy mildew does not infect other ornamentals, P. sparsa can also infect species of Rubus that include blackberry, raspberry and boysenberry plants.

Most rose cultivars are susceptible to downy mildew, but disease severity is variable. Leaves, stems, peduncles, calices and sepals can be infected, with foliage showing typically purplish to

brown lesions (Photos 1 and 2). The most noticeable disease symptoms are those associated with leaves and stems.

What makes downy mildew so difficult to control?

Plants outside of production areas, like roses and unmanaged caneberries (brambles) that are growing in landscapes and borders around nurseries, greenhouses and high-tunnel production sites, are possible sources of inoculum that can trigger a downy mildew outbreak. Plant debris from previous seasons may also serve as an inoculum source.

Environmental conditions, such as cool

weather and high humidity (64°F with a relative humidity of 85% or greater), are most conducive for disease development.

When these conditions occur, disease symptoms may appear overnight, especially in a greenhouse or high tunnel. Therefore, preventative fungicide applications in a rotation are critical to control downy mildew.

Why is it important to rotate fungicides?

Pathogen resistance to fungicides is becoming more common, and the performance of many fungicides has been affected to some degree by pathogens that develop resistance. So, using different

Photo 1. and 2.

Downy mildew symptoms on Pink Double Knock OutÂŽ rose leaves.

Table 1. mode-of-action fungicides in a rotation program is an important step toward reducing the risk of resistance development.

In 2016, the Tennessee State University (TSU) Ornamental Pathology Program conducted a study to evaluate fungicide rotations at 7- or 14-day spray application intervals for the control of downy mildew of roses. The initial fungicide application was Subdue Maxx 22ME (2 fl. oz./100 gal.) (a.i., mefenoxam) and Micora 23.3SC (4 fl. oz./100 gal.) (a.i., mandipropamid) and made after observing the first symptoms of downy mildew disease on the Pink Double Knock OutÂŽ roses. Then, Mural 45WG (7 oz./100 gal.) (a.i., benzovindiflupyr + azoxystrobin) and Segovis 1.67SC (2 fl. oz./100 gal.) (a.i., oxathiapiprolin) were alternated at 7- or 14-day application intervals (Table 1).

Both fungicide rotation programs equally and significantly reduced downy mildew incidence, as well as the average number of infected leaves per plant, when compared to the non-treated control (Table 2). Plants in the 7-day rotation program were also significantly taller compared to the non-treated control plants.

fungicide applications at times when the weather or environmental conditions are conducive to disease development. Typically, spray applications are made on a 7- or 14-day interval, depending upon the level of disease pressure. The sprayrotation program tested here worked well at both 7- and 14-day spray application intervals to control of downy mildew of roses, although disease pressure in this trial was lower than in the drench trial.

Other trials performed with different fungicides showed that a 7-day spray application interval was usually more effective when downy mildew disease pressure was high. By incorporating products that have both translaminar and systemic activity in fungicide rotation with other protectant fungicides, growers can likely extend their treatment interval while maintaining good protection.

incidence of downy mildew and reduced the average number of infected leaves compared to the non-treated control. The severity of downy mildew and disease progression among fungicide-treated plants were significantly lower in plants treated with the higher rate of Segovis (Figure 1). Additionally, all treatments resulted in significantly taller and wider plants compared to the non-treated control.

Benefits of using the drench application of systemic products in a treatment program were clear; one application provided excellent protection to rose plants for 30 days.

The TSU Ornamental Pathology Program conducted another study to evaluate systemic-fungicide drench applications for the control of downy mildew of roses.

Treatments were Segovis 1.67SC (1.0 fl. oz./100 gal. and 3.0 fl. oz./100 gal.) (a.i., oxathiapiprolin), Subdue Maxx 22ME (2 fl. oz./100 gal.) (a.i., mefenoxam), Plentrix SC (2.75 fl. oz./100 gal.) (a.i., azoxystrobin + mefenoxam) and Inosco 4.2L (20 fl. oz./100 gal) (a.i., potassium phosphite) (Table 3). Treatments were applied as a drench at the first signs of downy mildew, with a volume of 20 fl. oz. per 3-gallon nursery container.

All fungicide treatments significantly reduced the final disease severity rating, slowed disease progression, limited the

In the Field

Re-Invigorating

Tennessee’s Champion Tree Program

By Andrew Pulte, Ph.D., Bill Klingeman, Ph.D., and Sharon Jean-Philippe Ph.D., University of Tennessee

S

ince 1940, the American Forest, a nonprofit conservation organization, has maintained a list of the largest recorded, living tree specimens found across the continental United States.

These amazing tree specimens are located on both public and private grounds. As of 2014, a total of 826 trees, including 747 native and 79 naturalized trees, have received this distinctive honor in the United States.

Tennessee has had its own Champion Tree Program that was instituted in the 1970s to identify large tree specimens in Tennessee that meet the American Forest standards. From the onset of the Champion Tree Program, some 263 native Tennessee tree specimens statewide have been submitted, identified and recorded. These records include primary champions by species and also may include runners-up and notable specimens.

Champion trees were intended to be re-inventoried at frequent intervals to determine if they have succumbed to time, weather or pests and to ensure that these specimens continue to meet American Forest’s standards. Despite this objective, some time has passed since many of Tennessee’s champion trees were re-assessed.

To meet this need, and to re-invigorate this prestigious program, a collaborative effort was recently initiated to find and re-measure some of Tennessee’s largest known trees. We accomplished the first part of this challenge by creating a temporary internship program for University of Tennessee undergraduate and graduate students who had career interests that aligned with the program.

The Champion Tree Summer Internship was a collaboration between the University of Tennessee (Departments of Forestry, Wildlife and Fisheries, and Plant Sciences) and the Tennessee Department of Agriculture (Forestry Division). Through the internship, students had the opportunity to assist the state in the re-inventory of current champion trees across West, Middle and East Tennessee and update the current Assess Database.

Before student interns headed into the field to conduct the re-inventory, a full day of training led by Robert Leverett, treemeasuring expert, was conducted at the University of Tennessee. Students and faculty members were taught the approved methodology for selecting an appropriate portion of the tree to measure its circumference, crown spread and height. Additionally, students were tasked with transcribing the old hard copies of champion tree records into digital format.

Following this effort, the 2016 reinventory effort targeted 55 trees in 10 counties in West TN, 59 trees in 17 Middle TN counties and 77 trees in 14 East TN counties. Trees don’t have to be giants to be champions, which can make the task challenging. Several tree species, like Georgia Holly (Ilex longipes), can grow to be champions even with a comparatively small stature (Table 1).

We find that students participate in internships for a variety of reasons — to increase or reinforce core knowledge about a subject of interest, to expand their resume of experience, to gain practical skills, to increase opportunities for networking and to establish future contacts.

The Champion Tree Summer Internship afforded a truly unique opportunity for participating students to gain and reinforce core knowledge through practical field experience and expand their resume.

The Champion Tree field crew heads into the field in Middle Tennessee.

Pictured left to right (top), Jason Reeves (Host, UT Horticulture, Jackson, TN), Dr. Andy Pulte (UT Plant Sciences), Walker Fowler (UT FWF student) and (bottom) Chloe Reeves (UT PS student), Dr. Sharon Jean-Philippe (UT FWF), Mary Brand (UT PS student) and Ruxin Tao (UT PS & MLA student).

Sciences, said of the experience, “Measuring champion trees was an incredible way to spend a summer. All of the trees predated us, and it reminded me of my appreciation for the many wonderful and resilient species we have in Tennessee.�

Of the 191 target trees that were identified from transcribed ledger records, a total of 37 trees were located in west and middle TN. While some of these trees are truly spectacular, other trees, like champion blackhaw and red buckeye trees, may soon need a replacement nomination unless they can be conserved (Table 1).

After searching the listed tree locations, 14 trees in each of West and Middle TN were found to be dead. Another 20 trees in West TN (especially in Shelby and Fayette counties) and 29 trees in Middle TN (particularly Giles, Davidson, Grundy and Maury counties) were missing or could not be found. Often, there was little evidence remaining to hint at why trees were dead or missing. Storms, development and great age are often the causes of loss of champion trees to the state and communities.

When most champion trees across the state were originally inventoried, only traditional methods were used, with equipment that typically included older clinometers. For this project, the latest innovations in digital measuring equipment were employed. We were very interested to observe, though, that the older measurements of trees were extraordinarily accurate. Old trees don’t grow very quickly, yet many trees gave very similar measurements.

Graduate student intern Ruxin Tao recounted his experience as part of this project: “It was a fun experience to bring the latest technology to the champion tree re-inventory. Moreover, we had such a unique opportunity to not only see those giant green monsters, but also to meet great Tennesseans across the state who also loved these trees and had interesting stories associated with them.”

Future efforts in re-inventorying Tennessee’s tree resources will be focused on the 77 target trees that are recorded across 14 counties in East TN, which could not be completed due to the late start of the project. The crews can expect rough terrain and difficult field conditions in East TN, just as they had at the Savage Gulf State Natural Area in Palmer, TN. Once these East TN tree records are re-inventoried or dismissed, additional trees noted in the historic ledger records may be examined to identify the current record holders for key tree species in Tennessee.
