ow that we have made it through a very mild summer and transition into fall, hopefully everyone has begun their fall seeding and fertilizer program. This is the best time of the year to get out and enjoy this beautiful weather. If you need any guidance or if you ever wonder about what others around the state are doing for their programs, you can always reach out to your fellow members or any of us on the Board at MTC. Or you can always look for information on the University of Maryland extension website.
It’s hard to believe that our annual Conference is only a couple of months away. It will be held at Turf Valley Resort again this year on December 10th. We have lined up some of the best presenters around with great topics. Look for upcoming mailings or go to our website for registration info. We hope to see you there!
As always, please be on the lookout for events throughout the year from MTC and our partners at MASFMA. They are always a terrific opportunity to network and strengthen your connections and further your knowledge in the turf industry.
Let us keep growing together.
Your President,
Brandon Sands
Friends and Fellow Turfgrass Professionals of the Maryland Turfgrass Council (MTC),
I hope you all are ready for our fantastic 49th Annual MTC Winter Conference and Trade Show occurring December 10, 2024, at the Turf Valley Resort in Ellicott City.
Please take advantage of the Early Registration savings. You may utilize the registration form included and U.S. Mail, E-Mail or fax it back to us or if you prefer you can complete the form on our website www.MDTurfCouncil.org. Just complete and submit the form by November 7th. If you need more time to decide the next price break lets you register by November 28th. Your last chance to pre-register will allow registrations until December 6th, but please note, from November 29th to December 6th registrations MUST be completed only on the MTC Website. After that registrations will be accepted at the door.
So come join us and participate as a registered participant, get multiple quilt tickets, and consider becoming a Vendor and/or a Sponsor to showcase your company. This conference and your dues are the primary methods of raising funds for the MTC to utilize and support the research and activities of the University of Maryland Turfgrass Programs. This research and activities done through the Turfgrass Programs are critical for us, the turfgrass industry in Maryland, to keep up with the latest and best methods to protect our environment and provide our customers the high-quality turf they demand.
You can also take advantage of paying your dues with this year’s funds if you so desire. Dues paid now will cover you and your company up to January 31st, 2026. If you prefer to wait, we will invoice you in January 2025.
Your feedback is very important to us. As such we have changed the format to get you what you asked for. The continental Breakfast has been moved to the Trade Show floor from 6:30 to 8:30 AM to give you more opportunities to visit with the vendors right after you register and sign the sheets for your recertifications. At 8:30 we will have the Annual MTC Meeting, followed immediately by the keynote speaker, Mr. Michael Calkins, the Maryland Assistant Secretary of Agriculture for Plant Industries and Pest Management.
Have you ever considered being a part of the driving force of the MTC by becoming an Officer or Board Member? This is your association, and it is only as good as YOU make it. The Board meets 10 times per year and normally meets by Zoom. If you think you might be interested, please contact Ben Ellis, who is Chairman of the Nominating Committee at 571-340-0122, or give me a call at 443-742-6618.
In this issue you will find a conference registration, membership, and quilt ticket form, plus a sponsor and vendor form and a schedule for the day. If you have any questions or concerns, please feel free to contact me.
Unfortunately, I will not be at the conference due to having my right hip replaced, but Ben and the entire Board will be on hand to make sure this is a fabulous day for you. This will be the first conference I have missed since our first at the Sheraton in Landover.

Congratulations to Jack Cundiff
Turfgrass Producers of Maryland
Jim Claxton Memorial Scholarship Recipient 2024
Jack Cundiff is a rising Freshman at North Carolina State University, where he will be studying Turfgrass Science. He is originally from Northern Virginia, where he attended Brentsville District High School in their turf management program. Through the program, he gained numerous experiences that propelled his interest in the turfgrass industry. While at Brentsville, he participated in several trips including working on the field for the ACC Championship in 2022 and 2023, as well as the 2023 CONCACAF Gold Cup at the Bank of America Stadium. Furthermore, Brentsville competed in the 2024 SFMA student challenge and spoke at the Future of Sports Field Management session. With the help of Dr. Miller Ed.D. of Brentsville’s turf program, he landed a summer job at Robert Trent Jones Golf Club in Gainesville, VA where he gained valuable insights on what it was like to work at a high-level golf course. The past two summers, he worked at the Country Club of Fairfax, where he was trained to become a spray tech. He hopes to further his education at NC State through valuable internships in the summer and work at a local course. •

Major Pests and Control Programs for the MD Turfgrass Industry in 2023
PART 1: SPORTS TURF
By Dr. Kevin Mathias
Asurvey was conducted in the fall of 2023 to determine the key turfgrass pests within the turfgrass industry. The survey asked turfgrass professionals within the areas of sports turf, lawn care, sod production, and golf course management what their major pest problems were within the areas of insect, weed, and disease problems and what type of control programs were used. The major pest problems differed for each area of the turfgrass industry and was also related to the turfgrass species and/or cultivar that was being maintained. The graph below illustrates the difference in weed pests between lawn care and sports turf operations. For sports turf the key weed pests were goosegrass followed by crabgrass and annual bluegrass while in lawn turf Japanese stiltgrass was reported as a key weed pest by lawn care operators followed by crabgrass. Rough bluegrass and common bermudagrass were cited but in less frequency.
The concept of key pests, key plants, and key locations is a cornerstone in implementing effective IPM programs for the
turfgrass industry. Also, acceptable pest threshold levels varied depending on the type of turf and its intended use. The following article will examine these differences and similarities with regards to pest problems and control programs within the different components of the turfgrass industry. Due to the complexity and length of the article it will be delivered in four installments with the first one covering sports turf.
SPORTS TURF MANAGEMENT
Survey respondents in this area of the turfgrass industry covered the range of maintenance input levels from professional fields to county recreational fields and also the type of turfgrass that was being maintained. The major turfgrass species found on sports turf was bermudagrass followed by tall fescue and perennial ryegrass. Kentucky bluegrass by itself or seeded within a bermudagrass field made up a minority of sports turf fields
BERMUDAGRASS FIELDS
Over the past 20 years major improvement in the bermudagrasses with regards to turf density, lower mowing height tolerances, improved color, disease resistance, and winter hardiness has made the bermudagrasses the preferred species to find from county or school recreational fields to the collegiate and professional sports fields in Maryland. The major concern with the bermudagrasses is lack of color during dormancy and the likelihood of winter kill. The principal bermudagrass cultivars listed were ‘Tahoma 31’, Latitude36’, ‘Patriot’, ‘IronCutter’, and common bermudagrass.
2. The percentage of sports turf managers using bermudagrass cultivars. Often several different cultivars were used on different fields at the same facility.

To Our 2023 Advertisers
A number of bermudagrass fields are overseeded with perennial ryegrass to provide color for dormant bermudagrass turf. Color is an important quality factor for sports fields and is often demanded by stakeholder groups.
TALL FESCUE FIELDS
The tall fescue sports fields are often established at county recreation fields and/or at high school fields that are maintained at higher mowing heights. Treatment thresholds often are on an “as needed” basis except for preemergence crabgrass or goosegrass control.
KENTUCKY BLUEGRASS FIELDS
These fields are mainly found on baseball fields at the professional level such as Nationals Park / Oriole Park at Camden Yards or at several college baseball fields. These fields are often mowed at 7/8 to 1 1/4 inch. Due to visual (low pest thresholds) and playability requirements these fields are often treated preventatively for pests.
MAJOR PEST PROBLEMS
WEEDS
The major grassy weed pest was goosegrass, followed by crabgrass and annual bluegrass. The control products mentioned most often were Barricade (prodiamine), Dimension (dithiopyr), and Ronstar (oxadiazon). For effective goosegrass control Ronstar was the preferred choice and applied as a preemergence in the spring while Barricade and Dimension were the top two choices for crabgrass control. For bermudagrasses not overseeded with perennial ryegrass in the fall, Barricade was often used to reduce annual bluegrass germination.

Figure 4. A tall fescue field at a county park. Summer 2023.
Figure 3. Bermudagrass overseeded to perennial ryegrass at the UMD practice football fields in October 2021.
Sports fields that consisted of bermudagrass and overseeded to perennial ryegrass in late summer/early fall often were treated to remove perennial ryegrass in the late spring allowing a smoother transition to bermudagrass. The herbicides used were Revolver (foramsulfuron), Tribute Total (foramulsufuron, halosulfuron, and thiencarbazone), and Negate (metsulfuron and rimsulfuron).
The major broadleaf weed found in sports fields was clover with 60% of respondents indicating this weed, followed by nutsedge at 25%. With regards to broadleaf weed control practices a majority of the field managers indicated that they only applied broadleaf herbicides as a spot treatment. Phenoxy based herbicides were the herbicide of choice for clover while halosulfuron containing products such as SedgeHammer and ProSedge were used for nutsedge control.
Approximately 25% of sports turf managers did not apply herbicides or would hand weed if practical.
Cultural and mechanical programs that were mentioned to reduce weed encroachment included aerification programs, fertility programs to enhance turfgrass stand density, hand weeding, fraise mowing, and controlling traffic.
INSECTS
The major insect pests were white grubs with billbugs and fall armyworm as minor pest problems. Acelepryn (chlorantraniliprole) was used by a majority of the field managers (60%) followed by Dylox (trichlorfon) (30%) and Tetrino (tetraniliprole). Insect control decisions were based on pest history and on a as needed basis. Cultural programs to address insect pest damage were selecting insect resistant cultivars and promoting turfgrass growth to help in recovery of insect damage.
Figure 6. White grubs were listed as the major insect pest problem on sports turf fields.
DISEASES
The principal disease pests were based on the type of turfgrass. For bermudagrass fields spring dead spot was the key disease while on tall fescue fields brown patch was the major disease. Summer patch and dollar spot were the key diseases on Kentucky bluegrass fields. Also, the level of maintenance and restrictions on pesticide applications to fields would determine if disease control was applied preventatively, on an as needed basis, or not at all. A majority (60%) of field managers indicated that they applied fungicides on an as needed basis. However, if spring dead spot was present on bermudagrass fields or had a history on specific fields then a majority (80%) of managers would treat for this disease preventatively.
Native Grass & Wildflower Seed
On tall fescue fields brown patch and dollar spot were key diseases followed by red thread and gray leaf spot. On the Kentucky bluegrass fields that were present on professional and collegiate baseball fields and mowed at approximately 1" preventive disease control programs were in place to control key diseases such as summer patch, dollar spot, and brown patch.
Disease control practices encompassed both chemical and cultural programs. The cultural programs mentioned included selecting disease resistance cultivars, irrigation timing to reduce leaf wetness and disease development, and fertility programs that help reduce disease severity by promoting plant growth.
Disease control with fungicides varied with respect to the disease and turfgrass species. For spring dead spot in bermudagrass the preferred fungicide was Kabuto (isofetamid) or Velista (penthiopyrad). For summer patch on low mowed Kentucky bluegrass the strobilurin (Qol) fungicides such as Heritage (azoxystrobin) or Fame (fluoxastrobin) were applied. If sports turf fields had a low pest threshold, then a preventative disease control program was implemented and would often consist of fungicides in the DMI chemistry such as Banner Max (propiconazole), strobilurin chemistry such as Heritage, and the SDHI chemistry such as Emerald (boscalid). The multitarget chlorothalonil fungicide was also added to a spray program. •
