Summertime
in Alabama Once Again
S
ummer is here once more. Another school year is done, the hectic pace of our campus slows, and the talk in our shop invariably turns to what the weather will be like for the summer. Will we have 100-degree days, high humidity and drought, or will it rain so much we can’t keep the grass cut? Who knows? Much of the time, even the National Weather Service office on campus can’t say. As I’ve often heard, “This is Alabama. If you don’t like the weather today, stick around — it will change tomorrow.” That’s true much of the time. Speaking of weather, and fishing, a friend once said to me, “It’s never too hot or too cold to fish. It may be too hot or cold to get a bite, but it’s never too hot or cold to go.” With the Mole Cricket Deep Sea Fishing Tournament in full swing, if you like to fish, it’s a great time to get down to the Gulf, have some fun, and do some fishing. You might just reel in the winning catch! So, whatever weather may come your way, if you fish or if you don’t, enjoy your summer. See you at the beach!

The
Deep South Turf Expo is leveling all playing fields during its third year! The golf, lawn care, sports turf, sod production and landscape education repertoires coming this November are greening up. A review of the schedule posted below indicates the strength of our program. The core breakouts for the education sessions are being presented by some of the top names in turf in the Southeast, including Drs. Beth Guertal, David Han, Jason Kruse, Scott McElroy, Jay McCurdy, Maria TomasoPeterson, Casey Reynolds and Bryan Unruh. The DSTE is excited to add Dr. Eric Reasor to our program in November. Dr. Reasor joined the Mississippi State turfgrass team just this year. Bruce Williams, CGCS (Turf Republic), and Dr. Shawn Askew (Virginia Tech) will deliver keynote addresses. Williams’ presentation, entitled “Leading Your Way to Success,” is a blueprint for those in the turf industry on how to succeed! Mr. Williams emphasizes that successful managers must “shift the mindset from managing people to leadership. The key is to focus on leading a team, rather than managing staff.” His talk discusses effective ways to lead teams and achieve success in your position. Dr. Shawn Askew complements this theme with his presentation on “Thinking Outside the Box — Unusual Approaches to Unique Challenges.” Plans for the tradeshow are also underway, and registration is now open. Changes in scheduling have been made this year to give our exhibitors “Bang for the Buck!” The Tradeshow opens on Wednesday, November 8, following lunch and the general sessions. Some exciting putting contests are planned, as well as a 36-Hole Challenge, giving visitors an opportunity to win great prizes. Jerry Pate Turf and Irrigation will again host our Opening Reception. Following the reception, you’ll have the opportunity to participate in the silent auction and the business meetings of our hosting associations. The highly popular golf tournament returns to The Preserve Golf Club in Vancleave, Mississippi, to open the Expo. Challengers to last year’s winning teams are already pairing up. A special thanks to Stephen Miles, CGCS, and Jeremy Stephens for hosting the tournament again this year. A Skeet and Trap Tournament for our marksmen at Coastal Rifle and Pistol Club in Biloxi will also be held on Tuesday, along with the popular Sports Field Tour with Mr. Keair Edwards that features Gulfport SportsPlex, Goldin Sports Complex and the Biloxi Shuckers Stadium. Congratulations to the Gulfport SportsPlex, which recently achieved STMA environmental 8
certification and won STMA’s 2016 National Softball Field of the Year award. This year, our Softball Tournament and Dinner will be held on Tuesday night. This event was so much fun last year that we are duplicating all the winning components again this year, including the softball tournament sponsored by AQUA-AID and Regal Chemical. Take an opportunity to play on the gorgeous baseball field at Shucker’s Stadium, or watch your colleagues from the stands. A band will also be on hand, as well as outstanding food sponsored by Bayer and Harrell’s. It’s a perfect way to relax after a full day of opening events and exhibitor move-in. Be sure to register early and make your hotel reservations at our host hotel, the Beau Rivage, a five-diamond resort overlooking the Mississippi Sound. A link to the hotel’s online reservation service can be found on our website (www.deepsouthturf expo.org). Come play on our turf. Be part of this invaluable event exclusively for turfgrass managers across the southeast! v

P
ollinating insects are valuable organisms that we rely on for pollination services for crops, backyard vegetable gardens and certain ornamental plants. In the last decade, there has been concern about declining populations of bees and other pollinators. A general decline in pollinator numbers has been driven by the combined negative effects of habitat loss, diseases, parasites and misapplied insecticides. All of these issues must be addressed if we are to help pollinators recover and mitigate future impact. In the turfgrass industry, managers must be aware of these issues and be proactive to ensure that their methods do not contribute to losses in pollinator
12
populations. To that end, researchers have developed rational, scientifically based recommendations for best management practices (BMPs) that promote healthy landscapes, while conserving and enhancing pollinator health.
Follow label precautions, and practice insecticide stewardship.
Turfgrass stands are rarely devoid of weeds. Flowering weeds, such as the common dandelion (Taraxacum officinale) and white clover (Trifolium repens) among others, provide an important food source for pollinators, particularly as early-season forage for
bees that emerge in spring. Weeds in cool-season grass (bluegrass, fescue, ryegrass) lawns host 50 to 100 different species of bees, butterflies and flies. This demonstrates the need for us to consider the hazards to these insects from insecticide applications in turf. There are simple ways to reduce pollinatorsâ&#x20AC;&#x2122; exposure to insecticides. First and foremost, read and follow the label instructions on the insecticide you have selected. The wording on many insecticide labels has changed recently relative to pollinator conservation. The most common precaution is to avoid using insecticides on areas of turf with actively blooming weeds. This recommendation is the best way to min-

imize hazard from liquid insecticide applications that would coat flowers and taint pollen and nectar with insecticides. This is particularly important if you have a weedy patch of turf that needs an insecticide application.
Habitat loss is one of the biggest contributors to pollinator decline. Bees need flowering plants for both food and spaces to nest. As natural habitats disappear, so do food and nesting resources. To help combat this problem, provide the best possible habitat for these important insects by planting a
plants are suitable for planting in your area. In addition, the Pollinator Partnership offers free planting guides tailored to specific parts of the country at www.pollinator.org/guides. Finally, be sure to include resources for pollinators to use as nesting sites. For bees, you can construct domiciles out of pieces of hollow bamboo, or purchase pre-made â&#x20AC;&#x153;bee housesâ&#x20AC;? to station in your gardens. Plans for building bee domiciles are available online. To help out butterflies and moths, you will need to include larval food resources such as milkweed for monarchs or parsley for black swallowtails. You can learn more online about caterpillar food preferences. 13

diversity of flowering plants in your landscape. This ensures that pollinating insects with differing food preferences will have a variety of shapes, colors, and sizes to choose from and that there will be plants in bloom throughout the growing season. Past research has shown that plants like New England aster, bergamot, blackeyed Susan, purple coneflower, plains coreopsis, prairie coneflower and lanceleaf coreopsis can be quite attractive to a diverse array of pollinators.

•P opulations of pollinating insects have been reduced by habitat loss, disease, parasitic mites and misapplications of insecticides. We can take proactive steps to conserve these beneficial insects. • Avoid applying liquid insecticides to the blooming portion of flowering weeds like dandelions or clover. To accomplish this in turf, mow before application or use a granular product. • You can provide foraging habitat and
14
nesting spots for pollinators by planting a diversity of blooming plants that provide flowers at different times in the growing season. • If you are treating for belowground pests, consider using a granular — or spreadable — insecticide formulation. Granular products ensure that the insecticide residues go into the soil rather than into the blooms of flowering weeds. • If you must treat with a liquid insecticide formulation, mow the area you will be treating immediately before application. Mowing removes the majority of flowers, thereby reducing foraging pollinators. While some modern insecticides are systemic, current research for weeds in turf has demonstrated that any systemic transfer of insecticides into weeds poses no hazard to pollinators. • Controlling flowering weeds prior to or post-bloom with an herbicide before the application of an insecticide will also reduce the chances of directly contaminating flowers with an insecticide.
Note to readers
This publication was originally developed during the National Pollinator Summit for the Development of Best Management Practices to Protect Pollinators in Turf (August 21–22, 2016, Sheboygan, Wisconsin). The authors, in collaboration with more than 60 university researchers, Extension specialists, industry stakeholders (including lawn care professionals, golf course superintendents, managers and consultants) and product manufacturers have summarized and synthesized research and recommended management practices that protect pollinators in turf systems. This work was supported by the USDA National Institute of Food and Agriculture, Crop Protection and Pest Management Program through the North Central IPM Center (2014-70006-22486).

Turf Tips >>>
Three increasingly
Problematic Weeds in turf By Scott McElroy, Ph.D., Professor, Dept. of Crop, Soil, and Environmental Sciences, Auburn University
In
taking a walk on a golf course, or in any landscape for that matter, I enjoy observing the plant species around me. In observing, I automatically assume that the plants I see have always been in that landscape, when in fact the plants that currently exist in almost any human-disturbed or human-managed landscape are most certainly not the species that occupied that space prior to human activity. Very simply put, when people manage and change a landscape, plants change and continue to do so. Extending this idea further, I often assume that the weeds growing in a landscape or golf course are weeds that

have been there as long as that landscape or golf course has been there. I unconsciously assume that the weeds I see were a problem before I ever noticed that they were a problem. But, with greater observation over a greater period of time (we are all getting older, after all), it is obvious that new species are increasing, and some species are decreasing. Three weed species that are currently on the increase are doveweed, chamberbitter and cock’s comb kyllinga.
Doveweed (Murdannia nudiflora)
Fifteen years ago, doveweed was largely a coastal weed that was rarely seen north of Baldwin County, Mobile,
Doveweed flower.
or north of the panhandle of Florida. Even in those rare instances that it was observed further north, these populations did not persist past one year. Now, doveweed is becoming a common weed throughout Birmingham and Atlanta in home lawns, golf courses and sod farms. Doveweed is clump-forming, grasslike annual plant most notable for its succulent, hairless leaves. Doveweed produces small purple flowers with three petals, and each fruit produces three seed. Germination normally occurs beginning in June and continues throughout July. It dies off quickly when nighttime temperatures drop below 50°F to 55°F.
Doveweed seedhead.
Preemergence herbicides are typically ineffective for controlling doveweed. Lack of preemergence control is partly due to later doveweed germination relative to preemergence herbicide applications and the lower effectiveness compared to annual grass control. Specticle (indaziflam) can control doveweed preemergence, but applications must be made close to the time of doveweed germination. Postemergence herbicides can be effective, but control can be inconsistent. Celsius, Dismiss South and even some traditional three-way broadleaf

herbicides can be utilized for doveweed control. In any case, the addition of MCPP or mecoprop seems to enhance control of doveweed.
Chamberbitter (Phyllanthus urinaria)
Chamberbitter, also known as leafflower or phyllanthus, has become an increasingly common summer annual broadleaf weed throughout the southern US. Chamberbitter is easily identified by its pinnately compound leaf that resembles that of a silktree (commonly referred to as mimosa) leaflet. Flowers are born

on the underside of the leaf, and seeds burst open soon after forming. I remember learning to identify chamberbitter in undergraduate Weed Science in the late 1990s along with the similar species longstalk phyllanthus, which has stalked flowers born on the leaf underside. I also remember it then as more of a curiosity than a problematic weed. Today, however, chamberbitter is one of the most common weeds of home lawns, landscapes and ornamental beds throughout the southern US. Gallery (isoxaben) is typically more effective for preemergence chamber-

bitter control than all other herbicides. Gallery is a rarely used herbicide in turfgrass because it primarily targets broadleaf weeds rather than grasses. Other herbicides such as Defendor (florasulam), Celsius, metsulfuron and mixtures containing fluroxypyr are effective for postemergence control. New germination of chamberbitter seed can confound the observed control, necessitating repeat applications for control.
Al ab ama Tu rf Tim e s > >> Su mmer 2017
Cock’s comb kyllinga (Kyllinga squamulata)
Cock’s comb kyllinga is the most common sedge weed in turfgrass in Alabama. It has surpassed both yellow and purple nutsedge, as well as all rhizomatous perennial sedges (green and false-green kyllinga), all of which are seen as historically problematic in turfgrass. Cock’s comb kyllinga is a clump-forming, annual species (although it can possibly perenniate) that has the common aromatic fragrance possessed by other Kyllinga species. Seed have prominent, jagged edges for which the weed unusual name is derived. Cock’s comb kyllinga is seemingly easy to control, although regrowth or new seedling germination can occur, confounding observed control and often necessitating repeat applications. Common herbicides that are effective for cock’s comb kyllinga include Monument (trifloxysulfuron), Katana (flazasulfuron), Certainty (sulfosulfuron), Dismiss (sulfentrazone) and Dismiss South (sulfentrazone plus imazethapyr). Cock’s comb kyllinga is often present in green surrounds, which complicates applications since some herbicides can move off-target and damage sensitive greens. In these cases, Sedgehammer (halosulfuron) is a more appropriate herbicide for use, with the understanding that two applications may be needed for complete control. v

A
uburn University hosted its Turfgrass Research and Education Day on Thursday, March 30, at the Auburn University Turfgrass Research Unit. More than 130 attendees from all over the state participated in the event to to see first-hand research that researchers are conducting to improve our turfgrassmanagement practices. The morning was full of research tours and concluded with a lunch under the big top in the middle of the research center. To wrap up the day, twenty-eight golfers then hit the links at the Auburn University Club for the Poa annua Classic. All proceeds from this event will go directly to the Auburn University turfgrass program. Attendees viewed research plots and were educated on various topics including: “PGRs and Putting Green Research,” “Poa annua Control,” “On Toads and Bugs,” “Turfgrass Cultivars and Fertility Research,” “Control of Broadleaf and Other Miscellaneous Weeds” and “Identifying and Fixing Random Turfgrass Issues.” A big thank you to the sponsors of the Turfgrass Research and Education Day. Their support is of great importance to the success of this event. Please be sure to thank them personally when you see them. Plans are in the works to hold another Turfgrass Research and Education Day next summer. Be on the lookout for more details. v
