While working as a golf course superintendent, Drew never lost his love of the sports turf industry. He would frequently work as a volunteer at Regions Field during the SEC Baseball tournaments. “I missed the allure of the sports field where a major game would be televised with millions of viewers, and the product of your work would be on display. Sports turf is much more detail oriented than golf, and I always enjoyed working with a team and being part of a group effort on sports fields.”
Seven years ago, Drew interviewed with Jon DeWitt and was offered his present position. The pressure of this job wouldn’t be for everyone, but Drew thrives on it. “It’s the University of Alabama,” Drew says. “Everything must be correct as all eyes are on your product. Someone once told me ‘Pressure is a privilege,’ and I endorse that belief.”
And it’s a good thing Drew enjoys the pressure! He juggles seven different schedules on Alabama teams’ sports fields and works in the whirlwind that is Alabama football during the season. He works with his teams to keep the fields pristine and, more importantly, to keep everyone playing on them safe.
Because every minute counts, especially during football season, Drew enjoys spending as much time as possible with his family. Drew has been married to Crystal for 10 years, and they have a seven-year-old son, Andrew. He also enjoys helping coach Andrew’s baseball teams.
Drew is a valued board member of the Alabama Turfgrass Association and will serve as President in 2026. He is a longtime member of the Alabama Turfgrass Association, the Alabama Golf Course Superintendents Association and the Sports Turf Manager’s Association. Drew is also a member of the National Eagle Scout Association. We wish Drew every success at Alabama and as our incoming President.
MINIMIZING SPRING DEAD SPOT
By M. Aaron Tucker, Assistant Professor, Auburn University and Wendell J. Hutchens, Assistant Professor, University of Arkansas
Introduction
Spring Dead Spot (SDS) is one of the most persistent and damaging diseases affecting warm-season turfgrasses that undergo winter dormancy. First documented in 1954 on a bermudagrass lawn in Stillwater, Oklahoma, SDS continues to challenge turf managers across the southern and transition zone of the United States (Wadsworth & Young, 1960; Tredway, 2009). This article outlines the biology of the disease, key infection periods, and the latest cultural and chemical strategies for effective management.
Pathogen Biology
SDS is caused by soil-borne fungi in the genus Ophiosphaerella, specifically O. herpotricha, O. korrae, and O. narmari. These pathogens differ in geographic distribution and turfgrass host preference. In Alabama, O. korrae is likely the most prevalent species (Hutchens et al., 2025).
Disease Cycle and Symptoms
The fungi that cause SDS are ectotrophic root-infecting pathogens, colonizing the outer surfaces of roots, rhizomes, and stolons, leading to necrosis. This damage predisposes turfgrass to winter injury, with symptoms emerging in spring due to the combined effects of fall infection and harsh winter conditions.
Aerate and Play Right Away!
Decreased down time, increased revenue.
The surface is very “puttable.”
The dots are sand that is level with the turf.
DryJect® is a high-pressure, water based injection system that blasts holes through the root zone and fractures the soil profile. Plus, it automatically fills holes as it aerates.
DryJect® makes a big difference in playability … right away!
SDS is a monocyclic disease, with a single infection cycle per year. Infection occurs in late summer to early fall, when evening temperatures cool and soil temperatures drop consistently below 70°F. Symptoms appear in spring as circular or semicircular patches of dead turf, ranging from six inches to several feet in diameter. Severe outbreaks can result in large, coalesced areas of turf loss, with recovery taking two to three months after green-up—making proactive management essential.
Cultural Management Strategies
Effective cultural management hinges on understanding the disease's biology. Thatch and organic matter serve as reservoirs for pathogen survival. Practices such as core aerification,
verticutting, and fraze mowing during the summer remove thatch and dilute organic matter, thereby reducing inoculum and mitigating spring symptoms (Hutchens et al., 2025).
Conversely, cultural practices such as verticutting and aerification on symptomatic turf in spring can actually hinder recovery. Mechanical stress on already damaged turf slows regrowth, so spring cultivation should be avoided. Proper fertilization, particularly nitrogen applications in late summer/ fall and spring, supports plant health and recovery (Tredway, 2021; Hutchens et al., 2022). Ammonium sulfate has shown efficacy against O. herpotricha, while calcium nitrate is more effective against O. korrae—highlighting the importance of pathogen identification (Tredway, 2021).
A Merger that has Turf at Heart
Chemical Management Strategies
Chemical control with fungicides is most effective when timed correctly. Applications should occur during fall as soil temperatures drop consistently between 65-55°F. Current research is refining this window using the Battaglia-Hutchens cooling degree-day model to optimize timing (Battaglia et al., 2024).
The modern demethylation-inhibiting (DMI) fungicide mefentrifluconazole offers strong SDS suppression, while older DMIs like propiconazole and tebuconazole provide moderate efficacy (Clarke et al., 2020). Select succinate dehydrogenaseinhibiting (SDHI) fungicides—like isofetamid, penthiopyrad, and pydiflumetofen—also provide excellent control but carry a higher risk of resistance. Rotating SDHIs with DMIs is recommended to preserve efficacy.
Precision Application Technologies
Advancements in GPS-guided sprayers allow for targeted fungicide applications. Mapping disease areas in spring and early summer enables precise fall fungicide treatments, reducing both cost and environmental impact (Booth et al., 2021; Henderson et al., 2025).
Conclusion
Understanding pathogen biology, the disease cycle, and optimal application timing is essential for managing SDS. Continued research is uncovering pathogen-specific responses to cultural and chemical strategies, offering promising avenues for more refined and effective control.

Carotenoid Inhibiting Herbicides Increasing in Use DESPITE INJURY CONCERNS
By Scott McElroy, Professor, Auburn University
Gracie Cotter, Graduate Research Assistant, Auburn University
Debra Smitherman, Graduate Research
Assistant,
Auburn University
Carotenoid-inhibiting herbicides are valuable in turfgrass management. There are two carotenoid inhibitors available – Tenacity (mesotrione) and Pylex (topramezone). Tenacity has both pre and postemergence control of crabgrasses and some broadleaf weeds. When used in multiple application strategies they can control goosegrass and Poa annua as well. Pylex has become well known for control of goosegrass and also has activity on crabgrasses and miscellaneous broadleaf weeds.
On the face of it, these two herbicides seem ideal for use in turfgrass management; however, as anyone who has used them knows, it can be challenging to balance out the injury and the desired level of control. Both herbicides can cause injury to some, if not all, desirable turfgrasses they are labeled on. The injury presents as an intense white color, or as it is commonly called, “bleaching”. Even though tolerant turfgrasses may present with white or bleached symptoms, these symptoms can quickly abate, and turfgrass can actually be more intensely green post-recovery.
I (McElroy) began working on mesotrione for turfgrass uses in 2004 when I started as an assistant professor and extension specialist at the University of Tennessee. Jay McCurdy came on as a graduate student soon thereafter and worked on mesotrione use as well. Our research identified safety on cool-season grasses like tall fescue, Kentucky bluegrass, heat-tolerant bluegrasses, fine fescue, and centipedegrass. Mesotrione could even be used on seeded establishment of these grasses. Other warm-season grasses like bermudagrass, St. Augustinegrass, and zoysiagrass were more problematic. Mesotrione would not kill these desirable turfgrasses, but the bleaching was largely deemed unacceptable, limiting its broader use. And in case you did not know, mesotrione will control creeping bentgrass.
Topramezone testing began in the mid-2010s with similar trial work being conducted to determine turfgrass tolerance and weeds controlled. Early on, researchers could not decide how topramezone should be used. Pylex at higher rates (> 1.5 fl oz/a) combined with Turflon Ester (triclopyr) could control bermudagrass. At lower rates (< 0.5 fl oz/a) it could control goosegrass in bermudagrass. Such utility has its pros and cons. It is definitely a pro that a herbicide can be used for multiple things, but slight miscalculations in the rate might cause problems.
My lab has continued research on Pylex use in summer 2025. Pylex plus Drive has controlled smooth crabgrass to a nearperfect level; however, injury was “unacceptable” approximately 7 to 14 days after treatment (Figure 1). See the final comment below on what is “unacceptable.” Pylex alone also controlled goosegrass nearly 100% when applied to 3-4 tiller goosegrass. Injury at this location was more intense, which we attribute to dry conditions, that can cause increased bleaching. Bermudagrass recovered completely by 17 days at both locations.
Strategic Use is the Key
Regardless of these problems, interest in the topramezonebased product Pylex has increased, especially for goosegrass control. Pylex is highly active on goosegrass with control achieved at rates of 0.25 to 0.5 fl oz/a. Creeping bentgrass seems generally more tolerant than bermudagrass but that has not stopped use on bermudagrass.
Regardless of the bleaching injury with Tenacity and Pylex, the use of these herbicides is likely going to have to increase. There is simply too much herbicide resistance developing to not use these herbicides. However, I don’t want to lose this technology like we have lost other herbicide technologies. We must use these judiciously. First, tank-mix if possible. For goosegrass control in bermudagrass mixtures of Revolver, Celsius, or other herbicides with goosegrass activity may be an option. These herbicides are showing some safening effect as well, but safening can mean antagonism on weeds so follow up applications can be beneficial. Second, make sure you are using a preemergence herbicide to reduce the number of treated plants. Anderson’s goosgrass/crabgrass, other herbicides with oxadiazon, the granular flumioxazin Stayguard, standard pre herbicides like Barricade, Dimension, and Pendulum applied with Tower or Pennant Magnum are all options depending on the turfgrass scenario. Follow up with a carotenoid inhibitors or other postemergence herbicides to control any escapes.
Finally, we use the word “unacceptable” when it comes to injury. These herbicides are going to cause a bleaching-type effect to some desirable turfgrasses. However, we deem these as acceptable or unacceptable based on what we like or don’t like to see. Tolerant turfgrasses do recover, so to them the injury is acceptable; they simply are white, which some people do not like.

Southern Chinch Bug UPDATE
By David Held, Ph.D.
outhern chinch bugs (Blissus insularis) were recently introduced into Europe (Portugal) and are spreading especially in areas where St. Augustine lawns are common. This spread into Europe prompted my review of the literature and an update of any new knowledge on this pest. A literature search for new research on southern chinch bugs revealed relatively few new publications since 2020, despite the importance of this pest and damage potential in southern lawns. In my experience, industry support for insecticide research and not federal funding drives new information on many key pests. With relatively few new active ingredients being released for use in turfgrass in the last 5-10 years, this has limited support for applied research. This article will highlight three areas of importance relative to management of southern chinch bug in lawns.
Diagnostics and Lookalikes
Damage (yellowing or stunted grass that may also appear wilted) in St. Augustine or zoysia is most likely chinch bugs. Similar damage in bermudagrass could be chinch bugs but is more likely broad-headed bugs. Damage to bermudagrass from broad-headed bugs often shows up in August to September. Overwintering adult chinch bugs could begin feeding in spring and continue through summer. A close inspection where you part the grass should reveal these active pests and predatory true bugs. Turfgrass stands have many related insects with sucking mouthparts that look alike, yet not all are bad (Figure 1). Chinch bugs and broad-headed bugs are the most common pests, and minute pirate bugs and bigeyed bugs are common beneficials associated with these pests. The head and eyes of all life stages of chinch bugs are not wider than the body. Chinch bugs most resemble minute pirate bugs in coloration and size, but minute pirate bugs have a thickened, wider first segment to their beak (mouthparts). The heads and especially the eyes of bigeyed bugs and broad-headed bugs are wider than the body. The eyes of the predatory bugs are also large occupying almost the entire lateral sides of the head. These characteristics are easily seen with a hand lens.

CHINCH BUG BASICS
Chinch bugs are one of several important sap-sucking bugs in turfgrass. They are in the same order as ground pearls, mealybugs, and most things with ‘bug’ in the common name. These insects insert their thin mouthparts (stylets) into plant tissue as adults or immatures and feed on primarily phloem. While feeding, they also inject saliva which causes a range of symptoms from stunting and discoloration to death.
Chinch bugs are a complex of species in a single genus (Blissus) that runs from Canada to the Gulf of Mexico. Cool season grass managers up north struggle with hairy chinch bug while our foe is southern chinch bug. Southern chinch bugs are grass specialists so all grass including many weedy grasses can support populations. St. Augustine and zoysia varieties will support reproducing populations that most often results in an outbreak.
Chinch bugs overwinter as adults and begin feeding early in spring. They occur in aggregations of adults and immatures. Grass quality can impact survival, life span, and reproduction. Females, for example, on a good host can produce 10–30 eggs over a 10 week life span. A generation (nymphs to adults) is about 30 days, and 3 or more generations are expected in Alabama.
Chemical Control and Insecticide Resistance:
Real but Most Products Still Work
Insecticides are the primary way to manage southern chinch bug outbreaks of lawns. About 15–20 years ago, there was a considerable amount of data published on insecticide resistance among populations of southern chinch bugs in Florida. Although the potential for insecticide resistance is high, a recent test from Georgia suggests that pyrethroid insecticides are still working to control chinch bug populations. Insecticides for chinch bug management can be categorized by active ingredients, use restrictions, and residuals or systemic activity. First, the older chemistries (Dursban, Carbaryl, Acephate) are only labelled for use on sod farms. Pyrethroids (examples, bifenthrin, zeta-cypermethrin) are common in many professional and homeowner products. This group of products provide good contact activity with some extended (4 week) residual under lower chinch bug populations. Resistance to pyrethroid insecticides has been commonly reported for populations in Florida. Fortunately, those insecticide resistant populations can still be managed by changing the mode of action to another group like the neonicotinoids (imidacloprid, thiamethoxam, dinotefuran) or anthranilic diamides (e.g., chlorantraniliprole). Products in these two groups of active ingredients have systemic activity and produce the highest mortality when ingested during feeding. Because of the systemic activity, they may have longer residual control than products with contact only activity. However, not all systemic insecticides have good knockdown activity for large populations.
Misinformation on Non-insecticide Controls, Fertilizer, and Irrigation
The internet and now AI driven apps seem to abound with outrageous or impractical solutions (ex. dish soap, vacuuming the lawn, diatomaceous earth) to chinch bug problems. It is useful to review some cultural practices evaluated in published research studies.
Cultivars of St. Augustine grass vary in susceptibility. Common cultivars in Alabama (Common, Raleigh, Palmetto) are among the most susceptible cultivars to chinch bugs. Palmetto is often used in greenhouse and lab experiments to maintain colonies of these insects! This variety in lawns has a very high probability of being infested and damaged. Captiva, Floratam, and Bitterblue have resistance factors for chinch bugs. Thickened and lignified cell walls in resistant grasses prevent the thin stylet mouthparts of chinch bugs from penetrating cells around the phloem. All zoysia varieties in controlled experiments support about 5–10% of the populations produced on St. Augustine grass. Among the tested zoysia varieties, Cavalier supports the lowest (resistant) populations of chinch bugs and Palisades supports the most.
Irrigation, at even low levels, does not positively or negatively change chinch bug damage to turfgrass. A two-month research study from Florida found no impact on grass roots or clipping weight under the three irrigation regimes they evaluated. Chinch bugs density, more than drought, drives the severity of damage symptoms (wilting, etc) in infested St. Augustine. Irrigation can drive outbreaks of insect fungal pathogens among chinch bugs. This is more widely reported for hairy chinch bugs. Coupling high irrigation with fungal pathogens (like Beauveria bassiana) may be a strategy where insecticide use is limited.
Fertilizer applications, as low as 1 lb N per 1000 ft2, can increase populations or damage from chinch bugs. Populations of southern chinch bugs in St. Augustine grass plots that received 0.5 lb N per 1000 ft2 were similar to untreated plots. Nitrogen sources like ammonium nitrate that are faster to release have higher densities of chinch bugs relative to unfertilized and Milorganite-treated plots. The severity of damage in the same study was inconclusive. Damage was more severe early in plots with higher fertilizer rates. High fertility plots (1 or 2 lb N per 1000 ft2) were 100% damaged in 2–3 weeks, then those chinch bugs moved into and damaged the lower fertility plots. Low fertilizer rates will not prevent damage if chinch bugs are present, but it can delay the onset of damage or keep population densities lower.
De-thatching and proper mowing heights in lawns are other ways to reduce chinch bug populations. Why? It is unclear, but papers speculate the removal of eggs or laying sites (dethatching) or changing the microclimate for chinch bugs to develop as reasons. Lawn damage from chinch bugs is also correlated with increased weediness.
Natural enemies, particularly the predatory bugs mentioned earlier, are important to regulate populations of chinch bugs. If you look carefully into a chinch bug infested lawn, you likely see these fast-moving predators chasing their chinch bug prey like a lion after a gazelle. In a perfect world, these predators would increase in response to a chinch bug infestation and eventually greatly reduce or eliminate the population. However, we add fertilizer which allows chinch bugs populations to outpace their predators. And insecticides, like pyrethroids, can reduce chinch bugs but they are also broadly toxic killing most or all of the natural enemies. This is one advantage to newer chemistries like Acelepryn; they have lower toxicity to generalist predators than pyrethroids.
Managing chinch bugs is not impossible, but damage can occur more rapidly and extensively than most other turfgrass pests. This article outlined the key factors (proper diagnosis, understanding inputs) needed to be successful. If you apply these ideas, you will have fewer callbacks or losses due to chinch bugs.
