In this past Mays OTF Turf News, I shared with you a 2003 goal of theOhio Turfgrass Foundation (OTF), the OhioTurfgrass Research Trust

(O TRT) and The Oh io State University (O SU). Each group shares the

common vision of taking the OSU Turfgrass Program to higher levels of

excellence.

On August 26th, Dr. Stephen Myers, Chair, OSU Department of

Horticulture & Crop Science, led a meeting which included Dr. Bobby

Moser, Vice Presiden t and Dean , OSU College of Food, Agriculture and

Environmen tal Science, as well as representatives from OTF, OTRT and

OSU. The purp ose of the meeting was to present the common visionto OSU College Administration and make it a priority for development

at Th e O hio State University.

The Turfgrass Science Team, chaired by Joe Rimelspach, discussed a

documen t the team created entitled Opportun ities for Excellence.

The documen t outlined the Purpose and Mission of the Tur fgrass

Science Program, the History of the Program, and A Vision for the

Future. The most impor tant part of the document was the 11 different

fund-raising priorities that the Turfgrass team feels is necessary to retain

and improve its national and international stature. Each fund-raising pri-

ority has a Vision, Justification and Backgroun d, Projected Goals and

Endowment Goal.

On e of the visions that was discussed in length was the Professional

Golf Management (PGM) program. Dr. Myers sees this as a good fit for

the Tur fgrass Program. The PGM program will attract studen ts who will

serve the golf industry such as facility managers, service providers, busi-

ness consultants and sports professionals.

Dean Moser gave h is support on behalf of the College and The Oh io

State University. He believes the priorities outlined in the Opportunities

for Excellence document are the direction in which the Turfgrass

Program needs to go to be recognized as the finest in the n ation.

Congratulations to the Turfgrass Science Team for a great job creating

Oppor tun ities for Excellence. The O hio State University Tur fgrass

Science Program has a clear Vision for the Future.

Message FromThe President



Abeautiful, sunny day in the mid-eighties wel-

comed 423 tur fgrass professionals for the 2003

Oh io State University/ OTF Tur fgrass Research

Field Day, August 13 at the OTF Research &

Education Facility. After welcoming comments fromOTF President John Mowat, Dr. Bobby Moser, Dean,

OSU College of Food, Agriculture, and Environmental

Sciences, thanked O hios tur fgrass industry for sup-

porting OSUs Turfgrass Program, making it one of

the premiere programs in th e countr y.

Next, Linda Heyl, Director of Development, Food,

Agricultural, and Environmental Programs thanked

those in attendan ce for financial support of the turf-

grass program, specifically for the industrys support

raising funds for the James Beard Graduate Fellowship

in Turfgrass Physiology/ Biochemistry (reported in the

July/ August 2003 issue of Tur fNews). Heyl comment-

ed that in all her years with O SUs DevelopmentDepartment, she has never seen as strong of support

for a program than received from the tur fgrass industry.

OSU Turfgrass Program spokesman for the day,

Dr. Mike Boehm, OSU Department of Plant

Pathology, explained the field days format an d

divided the group into Golf Course and Sports/

Lawn/ Grounds tours.

Gener al Session, Tuesday,December 9, 4:00 pmEarle Bruce

A Winning AttitudeCoach Earle Bruce is most well known to

most of us as being the head coach of The Oh ioState University football team for nine years,where he comp iled an 81-26-1 record. He was anassistant coach to Woody Hayes when they wonthe national championship in 1968. CoachBruce has been n amed Coach of the Year inthree different major conferences. He coachedin four post season all-star bowl games and wonall four. In addition, he coached in 12 regularpost season bowl games.

For several years, he also coached with greatsuccess in the Arena Football League. Recently,

he has written two books and is a part of theOSU football coverage on radio. He and his wife, Jean, have four daughters andsix grandchildren. In December, he was inducted into the College Football Hallof Fame.

Keynote Speech: WednesdayDecember 10, 9:00 amLar r y Bar net tBaseball Fr om Behind The Umpir es Mask

Larry Barnett is a native of a smallOhio town. After graduating from

high school, he entered umpire

school in Florida. He officiated in the

minor leagues for five years and in

1968 became the youngest major

league umpire in h istory. He umpired

for 31 years, having retired in 1999.

He has been praised by many of the

old pros that preceded him and

admits that some have had other com-

men ts, too. You m ight have though t that umpires were stodgy old

men with weak eyes and a slow wit. Well, heres a man who takes

delight in refuting th at. He certainly isnt stodgy and has anextremely quick wit.

He has um pired in 8 American League Playoffs, 4 World

Series and 5 All-Star games. One of Larrys most controversial

calls came in the 3rd game of the Super Series of 1975.....

Naturally Barry was right again.

Much of the hard work, sweat and jeers that make up this

nations number one sport is often very humorous. Larry will

share some of that with us in his talk titled BASEBALL FROM

BEHIND THE UMPIRES MASK.

High Pressure Water InjectionDuring the 1990s high-pressure water injectiondevices like the Toro Hydroject were developed to

help alleviate soil compaction on tur fgrass greens.

The advantage to this procedure is the variable

depth in pen etration that could be achieved with lit-

tle surface disruption . Research at Michigan State

University (Murphy and Rieke, 1994) showed that

high-pressure injection was much more effective in

relieving compaction as measured by soil physical

properties than hollow tine coring. High-pressure

water injection does have the advantage that it can

be used continually. I would recommend that the

interval between uses not be less than 3 weeks. Root

damage can occur with frequent use of this technol-

ogy.

Conclusion:Coring is an important management practice.

The effectiveness of this practice is dependent on a

clear focus of what the desired end result is.

ThatchCoring and rem oving the core results in no perma-nent reduction in thatch (the organic fraction). The re-

incorporation of the cores can reduce through dilution

the thatch layer. In general, coring in combination with

other managemen t practices like topdressing, and

aggressive vertical cutting will help in thatch manage-

ment.

Poa annuaCoring during the autumn potentially increases the

opportunity for annual bluegrass invasion. Recently

reported findings out of Penn State University has

found that the potential for Poa annua invasion is less

when solid tines are used versus hollow tines. A possible

reason for this is that with hollow tines the soil brought

to the surface also brings Poa annua seeds. This is the

only advantage I see for using solid tines over h ollow

tines this time of the year. Also, be sure to core cultivate

when the turf is actively growing. Quick recovery of the

core h oles will reduce the poten tial for weed invasion,

and also provide a better putting surface.

Residential TurfTips

Lawns are a central part of our landscapesthroughout North America, and have emerged as

the dominant land use in rapidly expanding subur-

ban areas. Besides their aesthetic and recreational

value, lawns have significant mitigating effect on

global warming due to their tremendous capacity to

sequester atmospheric carbon and mitigating the

heat island effects. In fact, a recent repor t from

Colorado indicates that carbon sequestration in tur f

soil occurs at a rate comparable to the land that isplaced in the Conservation Reserve Program in the

USA. In this report, the scientists analyzed historic

soil data from many tur fgrass sites. The data show

that carbon sequestration continued for up to 31

years in fairway type of turfgrass after its initial estab-

lishment.

Plants capture atmospheric carbon dioxide to

make their own food ( carbohydrates) with the help

of the sunlight. Well maintained lawns capture

more carbon dioxide than the poorly maintained

lawns with bare ground patches. These carbohy-

drates are stored in p lant tissues including leaves,

stems, and roots. The clippings have a portion of

this captured carbon. This carbon along with nitro-

gen ( in the form of proteins) stored in th e clippings

serves as the main source of food for numerous soil

microorganisms and invertebrates that perform impor-

tant functions such as nutrient release for plant growth

and fighting plant diseases. To considerable extent,

returning the clippings to the soil actually reduces the

amount of fertilizer needed for the lawn.

Unfortunately, some homeowners still bag the clip-

pings and send them to th e landfill. Excess grass clip-pings are a problem not on ly for the land -fills, but also

for the mun icipal composting facilities, where th e large

amounts of clippings arriving in spring and summer can

overload the system with high nitrogen material and

turn the process anaerobic, resulting in air pollution vio-

lations from the odors of methane, ammon ia, and o ther

gasses released.

Carbon sequestration is one of the main argumen ts

used for saving the rain forest. Lawn is like a piece of

the rain forest right in our backyard. The homeown-

ers with well maintained lawns are contr ibuting th eir

share to the reduction in global warming by capturing

the excess carbon d ioxide from our environmen t. Well-maintained lawns also protect topsoil from wind and

water e rosion, absorb and filter run-off water, and

reduce noise and glare.

Sports TurfTipsFrequently AskedQuestions This FallPamela J. Sherratt, Dr. John R. Street and Dr. Karl DannebergThe Ohio State University Department of Horticulture & Crop Science

How can we remove roughbluegr ass (Poa t r ivialis)?

Large amounts of rough bluegrass in turf are

most obvious in the summer because they go dor-

mant (brown). Rough bluegrass (RBG) is a persis-

tent perennial weed grass that is incredibly aggres-

sive in the spring and fall, making it a strong com-

petitor in turf, especially on those areas that lose

grass cover ( between hashes etc.).

Unfortunately, there is no selective herbicide

available to control RBG in a tur f situation.

Furthermore, turf areas that have been renovated may still

become infested with RBG if there is an appreciable

amount of RBG seed in the soil.

If the RBG infestation is unacceptably large, one option

is to renovate the field by killing all the turf and starting

over. Killing the grass can be achieved by applying a non-

selective herbicide or a soil fumigant such as Basamid( r) ,

which is an alternative to methyl bromide. The added

advantage of using a soil fumigant, either on its own or in

conjunction with a selective herbicide, is the soil steriliza-

tion process, which should prevent weed seeds from

emerging. There are clear application guidelines on the

label and there is a short time period before the field can

be re-seeded/ sodded.

Clearly, with all weed problems,

the best method for control is preven-

tion. A healthy, dense sward of grass is

far less likely to be infested with weeds

than tur f that is stressed or over-worn .

Note: RBG is discouraged by deep &

infrequent irrigation, p roper mowing

(i.e. not scalping the grass), good

drainage, and sports traffic. In addi-

tion, using good quality seed may be

more expensive, but is less likely to becontaminated with RBG.



15/24

Following fall core aeration,should the field be topdressed?

Adopting a topdressing program requires some

forethought & investigation .

Native soil fields that are extremely prone to com-

paction, with little or no organic matter in the soil, arecandidates for a topdressing program. The ultimate

aim is to improve sur face drainage capabilities.

A good quality topd ressing mix of 80% sand and

20% compost at 1/ 4 inch depth each spring is an

option. The m ix costs around $12/ ton, with up to 50

tons applied following aeration in the spring. The

material alone will cost approx. $600. A contractor will

charge around $33 per 1000 sq.ft for1/ 4 inch top-

dressing depth. This would need to be done every year

(spring) with the same material. Changing/ amend ing

the existing native soil is a long-term effort, the results

of which may not be apparent for several years, or until

the soil reaches at least 75% sand by weight.

When is the best time to controlbroadleaf weeds?

In the fall. Best efficacy from broadleaf weed herbi-

cides occurs when conditions are optimal for absorption

and translocation of the herbicide downward in the

plant (i.e. usually when the weed is actively growing). In

the fall, broadleaf herbicides and sugar compounds are

usually transported downward. Late fall

broadleaf weed applications can be very effective

as long as the weed foliage is in a green, active

physiological condition to absorb and translocate

herbicide.

Beware! Broadleaf weed herbicides can be

injurious to seedling tur fgrasses. Where

seedlings are present from over-seeding, most

broadleaf herbicides cannot be used un til

seedlings have matured and been mowed at least

three times. Seedling turfgrass can be treatedsafely with bromoxynil (Buctril). Best weed con-

trol with bromoxynil is achieved if the weeds are

less than 2" tall when treated. 2,4-D can safely be

used on young turfgrass provided the turfgrass

has been mowed at least three times and the use

rate does not exceed 1.0lb ai/ acre.

Creeping bentgrass is a widely used tur fgrass

species on golf course greens, tees, and fair-

ways in the northern United States. A disad-

vantage of creeping bentgrass is its vulnerability to a

wide range of pest problems. Ann ual bluegrass is a

serious weedy grass problem on creeping bentgrass

putting greens. No herbicide chemistry is available to

effectively selectively control annual bluegrass in

creeping bentgrass.

Glyphosate, the active ingredient in Roundup

brand herbicides is a broad spectrum herbicide that is

toxic to plants, fungi, and bacteria. Glyphosate resis-tant crops have been developed by genetically engi-

neering plants with a gene that codes for an EPSP syn-

thase protein with lower sensitivity to glyphosate. The

Monsanto and Scotts Companies have collaborated in

the development of genetically engineered creeping

bentgrass cultivars that are resistant to glyphosate via

the h eterologous expression of a gene from the CP4

strain of Agrobacterium sp. encoding for a glyphosate

resistant form of EPSP. Adoption of glyphosate resis-

tant creeping ben tgrass could poten tially simplify and

improve th e con trol of a wide array of invasive an nual,

biennial, and perennial grass, broadleaf, and sedge

species that can invade golf turf. The availability ofglyphosate as an over-the-top treatment on glyphosate

resistant creeping bentgrass could significantly reduce

the need for many of these herbicides, resulting in

several important environmental, health, and safety

benefits. It is less likely to leach than most other tu rf

herbicides. It has low toxicity to mamm als, birds, and

fish and it is one of the few commercially available

herbicides classified as Categor y E by the EPA (evi-

dence of non-carcinogenicity for humans).

Concern over the release of transgenic varieties

has arisen, specifically with the competitive ability of

transformed varieties. Therefore, this study was per-

formed to determine whether the relative competitive

growth of several glyphosate resistant creeping bentgrass

lines is equivalent to traditional creeping ben tgrass when

transplanted into a mature and competing turf stand.

Materials and MethodsCreeping ben tgrass plugs (Table 1) were established

from stolon nodes grown in Jiffy Pellets (42 mm dia.) in

Gervais, Oregon. The plants were irrigated to preventdrought stress and fertilized to eliminate visible nutrient

deficiencies. Plants were maintained at 1.25 cm height of

cut. Plants of similar age and size were selected for planti-

ng in established turf environments.

A field study was initiated on June 23, 2000 in

Marysville, OH. Companion studies were also conducted

in New Jersey and Oregon. The Kentucky bluegrass turf

area was maintained for uniform turf coverage and sur-

face drainage. Soil cores (35 mm in diameter and 60 mm

deep) were removed from the original turf area on 60-90

cm centers with an auger bit. Bentgrass plugs were trans-

planted directly into the core holes so that the crowns of

the plant were at or slightly below the soil sur face and sothat firm contact between the Jiffy pot media was main-

tained with the field soil. The turf area was maintained

under a regime appropriate for the original dominant

species following an initial establishment phase to accli-

mate the bentgrass transplants.

The plots were irrigated as needed to prevent stress

during a six-week establishment phase, and then irrigat-

ed to maintain the existing turf. Plots were mown regu-

larly at a clipping height of 1.25 cm in Oregon, of 3.75

cm in New Jersey, and of 5 cm in Ohio. Nitrogen (36.6

kgha1 per month during active growth) and other nutri-

ents were applied as needed to compensate for visualdeficiency symptoms. Herbicides, insecticides and

fungicides were applied as needed to control the

integrity of plots, following standard agronomic prac-

tices.

Bentgrass plant diameter was measured in cen-

timeters during the first week of each month of the

growing season. Mean plant diameter was calculated

as an average of two perpendicular measurements

made on each tiller plot. Field Monitoring data was

collected month ly noting the presence and inten sity

or absence of disease ( dollarspot, brownpatch, take-all

patch, Pythium , etc.), beneficial or p est insects (White

grubs, cutworms, etc.) or other vertebrates and inver-

tebrates (earthworms, etc.). Observations of plant phe-

notype and weediness characteristics were also collect-

ed.

The study was conducted as a completely random-

ized design in three replicates at each of three loca-

tions. The mean diameter was calculated as the aver-

age of the longest and shortest diameter of each ben t-

grass tiller plot. Analysis of variance was used to deter-

mine differences in growth among the bentgrass lines.

Means were compared using Fishers protected LSD.

Results and DiscussionGrowth of all the creep ing ben tgrass cultivars and

lines was significantly greater in O regon as compared

to New Jersey and Oh io (Analysis not shown) . The

increased growth recorded in Oregon may have been

due to more favorable growing conditions in Oregon

such as the Mediterranean climate and extended frost-

free per iod. Additionally, in Oregon the h eight of cut

was 1/ 2 inch and ben tgrass is more tolerant of low

clipping heights than either the Kentucky bluegrass

and perennial ryegrass turf. In both New Jersey and

Oh io, the h igher height of cut may have favored thebluegrass over creeping bentgrass entries. Other fac-

tors may also have contributed to the differences

between locations including soil type and cultivars or

species composition in the test plot.

At all locations, no differen ces between the refer-

ence, non-transformed or transformed lines were

observed when monitoring disease incidence, insect

susceptibility, presence or absence of ben eficial organ-

isms, plant growth characteristics, or aggressiveness

character istics on any date.

No-statistically significant differen ces in growth

were observed for any date at the Marysville, Ohio

location (Table 2). The density of the Kentucky blue-

grass stand as well as competition from broadleaf

weeds, such as dandelion an d white clover, resulted in

more variation among replications of the same cultivar

or line than were observed between cultivars and lines.

ASR 368, ASR 333 and ASR 365 were all statistically

equivalent to their n on-transformed parents and to

commercial cultivars throughout the study period.

Transgenic creeping bentgrass lines that are resistant

to glyphosate displayed no additional increase in vege-

tative growth or relative fitness compared to trad ition-

al non-transgenic creeping bentgrass when competing

with other species such as Kentucky bluegrass and

perennial ryegrass maintained as turfgrass. The results

from three diverse environments (New Jersey, Oregon,

and O hio) ind icate that the expression of the gene for

glyphosate tolerance conferred no competitive advan-

tage compared to non-transgenic creeping bentgrass-

es. These results indicate th at the relative fitness of

transgenic lines of creeping ben tgrass is within th e

normal range of values for other com mercially avail-

able cultivars. Therefore, these transgenic lines would

not be expected to have a competitive advantage in

vegetative growth over non-transformed creeping

bentgrass in either managed or unmanaged ecosys-

tems. The variability in creeping bentgrass growth

observed in this study is less than that typically

observed due to differences in climate and cultural

practices, such as mowing, irrigation, and fertilization.

The results of this, and many other studies, are

part of a petition that was subm itted to APHIS for

review to deregulate Roundup Ready creeping bent-

grass and make it commercially available. The review

process is quite lengthy and can take 18 months or

longer to complete. If the review is favorable,

Roundu p Ready Creeping Bentgrass could appear on

the market sometime in late 2004 or 2005.

Invasive species, be they weedy plants, exotic insects orpathogens, zebra mussels in our waterways, or even rabbits

imported to Australia have been a problem for ecosystemsand for human activities for centuries. They literally are a prob-

lem that will not go away, so we need to learn more about inva-sives and their management. Think about how they affect us in

horticulture, from gypsy moths that a good portion of Ohio nowfaces, to the emerald ash borer from Asia that is a serous threat

to ashes in woodlands and landscapes if it spreads from itsintroduction to Michigan. From the historic devastation of fungalpathogens to the U.S. in the past century with chestnut blight

and Dutch elm disease, to the threat imposed by sudden oakdeath caused by Phytophthora ramorumon the West Coast.

From kudzu to Japanese knotweed, from dogwood anthracnoseto, well, to our discussion in this article of an invasive you

should knowgarlic mustard.Garlic mustard (Alliaria petiolata) is an invasive herbaceous

biennial weed that hails from Europe and which was brought tothe Americas as an herb or culinary plantthe rest is history. Itwas first reported in the U.S. on Long Island in New York in

1868 and in Ohio a bit later, on Lake Erie islands at the dawn ofthe 20th century in 1899. For unknown reasons it is become an

increasing problem in forests, in botanic gardens and arboreta,in landscape plantings and in parklands. One of the features ofgarlic mustard is that its appearance changes from its first year

to its second year in its life cycle, making identification difficult.Best control involves use of glyphosate herbicide on first year

growth or very early hand-pulling in the second year of garlicmustard s life cycle to prevent seed production.

A key feature of the biology of garlic mustard is that it is anon-woody biennial herb, producing only short stems andleaves in its first year after seed germination, with longer stems,

leaves, flowers, fruits and seeds in its second year of growthbefore it dies back. The rosette of first year leaves persists as

green tissue well into the fall and winter. Garlic mustard flowersin early spring, about the time that spring beauty (Claytonia vir-

giniana) blooms (early April for most of Ohio). Seed produced inthat second year may survive in soil for up to five years andpossibly longer.

An InvasiveYou Should Know

The first year plants are distinctly different from the sec-

ond year plants. Leaves occur in a basal rosette and theplant is only several inches in height. The leaves are small,scalloped and kidney-shaped with a mild garlic aroma. In the

second year of growth, the stem elongates to 3-4 feet inlength, leaves are triangular and sharply toothed, and tiny 4-

petaled white flowers and long slender seedpods ( siliques )develop.This is when most people really become aware of

the extensiveness of their garlic mustard infestation.OSU weed ecologist John Cardina points out that garlic

mustard is a successful invasive for several reasons. It pro-

duces large amounts of seed. In its first year of growth asnoted, the rosette of kidney-shaped leaves are often uniden-

tified as garlic mustard. It is not beloved by deer. It isbelieved to produce allelopathic chemicals which deter

growth of other plants competing for the same niche. Garlicmustard also thrives in rich woodland or garden sites with

high earthworm activity and rates of organic decomposition.Which brings us to control. Because the rosette of first

year leaves is green and growing in the fall and into the cold

of winter it can be controlled with glyphosate herbicide (eg.Roundup) which is absorbed through the leaves and then

translocated to the roots, killing the garlic mustard plant. Thiscontrol approach is particularly effective because these aretimes when glyphosate can be applied without non-target

damage to other plants which are dormant during that peri-od. Hand-pulling second year plants is risky as a control

measure if garlic mustard has reached even the early flower-ing stages. Research shows that viable seed may be pro-

duced even on flowers of plants that are pulled up and left inthe garden or parkland site. Only if pulled flowering plantsare bagged in plastic or completely removed from the site

will control with hand-pulling be assured.So, the story with this invasive is fairly positive.Though

they can be quite a pest - there are control options. Hopefullywe can be as successful with management strategies for

other invasives that are currently challenging horticulturists.

We tend to think of weeds and insects as

separate and independent concerns in turfgrass

management and, to a large extent, our

approach toward research and extension reflects

this way of thinking. However, most biologists

would admit that there can be a great deal of

interdependence among these components, even

if it isnt always obvious. When turfgrasses are

attacked by insects such as bluegrass billbugs or

white grubs, their ability to compete with

encroaching weeds is compromised. Worse yet,

when turfgrass plants die as a result of insect

damage, the new occupant of the formerly turf-

grass covered site will likely be a weed. Therefore

insect resistant turfgrasses, such as endophyte-

enhanced varieties, could provide some measure

of resistance against weed invasion by reducing

the amount of damage caused by insects.

For the last 8 years, my research has focused on

identifying and describing linkages between the vari-

ous par ts of turfgrass ecosystems in order to develop

biologically based turfgrass managemen t programs. As

a Ph. D. student working in the laborator y of Dr. DavidShetlar, I was fortunate to have stumbled upon the

idea that endophyte-enhanced turfgrasses may change

the dynamics of a healthy turfgrass system. While my

primary goal was to evaluate how introducing endo-

phyte-enhan ced grasses into p re-existing stands might

influence insect pest populations, I also noticed an

interesting change in the composition of these stands

taking place. Because I was overseeding stands of

Kentucky bluegrass with endophyte-enhanced perenni-

al ryegrass, I expected stand composition to change

from primarily bluegrass to primarily ryegrass over

time. However, I didnt necessarily expect to see insec-

ticide applications influence the speed at which thistransition took place!

In p lots receiving insecticide, the tran sition from

bluegrass to ryegrass took place more slowly than in

plots not receiving insecticide. The culprit of this oth-

erwise un expected ph enom enon was the bluegrass

billbug. By preferentially feeding on Kentucky blue-

grass, the billbugs were facilitating the transition

toward endophyte-enh anced (resistant) peren nial rye-

grass. This observation implies that by feeding on pre-

ferred turfgrass plants, insect pests can promote

encroachment of less favored (by the insect) species.

Unfortunately, under most circumstances these less

favored species are likely to be weeds.

For the last 3 years, Ive been fortunate to work as a

Post-doc in th e laboratory of Dr, Parwinder Grewal at

the OARDC in Wooster. In Dr. Grewals lab, Ive been

able to take a closer look at how fungal endophytes

and insects influence the composition of turfgrass

stands and have been able to incorporate insect para-

sitic nematodes into the mix. I have also worked close-

ly with Dr. John Cardina (Department of Horticulture

and Crop Science, OARDC) to understand h ow these

differen t pieces (plant resistance, insect herbivory, and

biological controls) influence competition between

turfgrasses and common weed species.In a series of low maintenan ce field p lots seeded

with endophyte-infected or uninfected perennial rye-

grass or tall fescue, weve been observing weed density

and cover three times a year for the past 3 and a half

years. Some interesting patterns have emerged that

indicate both grass species and endophyte infection

can influen ce the type and severity of tur fgrass weed

problems. There was a tendency for weeds to be more

of a problem in tall fescue p lots during the first year

after establishment. However, tall fescue has slowly

crowded out encroaching weeds over time and these

plots now have fewer weed problems than the ryegrass

plots. This pattern makes a certain amount of sense

when you consider the establishment and growth

characteristics of these two grass species. Although

perennial ryegrass establishes more quickly than tallfescue, it lacks the deep root system and ability to

spread by rhizome. Therefore, perennial ryegrass pro-

vided greater cover and had less extensive bare areas

available for weeds early in the study, but its recupera-

tive potential, long term vigor, and persistence were

somewhat less than that of tall fescue which proved to

be a stronger competitor over time.

Endophyte infection was also an important factor

in these p lots. The density of Plantago (common and

buckhorn plantain) was lower in stands of endophyte-

infected tall fescue compared to stands of uninfected

tall fescue whereas cover by healall (Prunella vulgaris)

was lower in stands of endophyte-infected peren nialryegrass compared to uninfected stands. Weve also

been busy in the greenhouse trying to tease apart th e

various aspects of turfgrass-weed competition. From

our findings to date, it appears that endoph yte infec-

tion can definitely enhan ce the ability of tur fgrasses to

compete with weeds, such as dandelions, in the pres-

ence of sur face feeding insects, such as armyworms.

However, endoph ytes seem to provide little benefit to

turfgrass plants in the presence of soil feeding insects

like white grubs. Noteworthy however is the observa-

tion that the grubs themselves are capable of exacer-

bating weed problems by reducing the ability of turf-

grasses to compete, even when grub densities are rela-tively low.

The role of biological contro ls, such as insect para-

sitic nematodes, in determining competitive interac-

tions between turfgrasses and weeds is much the same

as that of an insecticide. In greenhouse studies using

the fall armyworm, insect parasitic nematodes bol-

stered the competitive ability of both perennial rye-

grass and tall fescue by killing armyworms before they

caused exten sive damage to the grasses. Dandelion

plants growing in competition with either grass were

smaller and had fewer leaves when insect parasitic

nematodes were p resent.

My future research plans include studies aimed at

improving implementation of IPM in turfgrass by

comparing the biological, aesthetic, and economic

characteristics of a range of turfgrass management

approaches. With collaboration from various

researchers at Ohio State and elsewhere, I hope to

continue to tease apart the underlying relationships

between endophytes, plants, insects, and biological

controls to help build more sound, biologically based

turfgrass pest managemen t p rograms.




Message From YourExecutive Director

Attending state, regional and national conferences and trade showscan help everyone grow professionally. This is certainly true for turf-

grass managers.Leading turfgrass researchers and university educators lead and

conduct many of the educational sessions. Peers who have faced simi-

lar situations as you, often share their experiences in panel discussions.

This is a great chance to ask questions and learn from others who have

already tackled th e challenges with which you are faced.

Lets not forget about the exhibitors in the trade show. Suppliers

should not be looked at as another sales person to avoid. Establishing

relationships with suppliers can p rove to be your biggest ally. Of course

they want you to buy their p roducts and services. But they are also

there to help you. Many exhibitors bring leading experts to trade

shows to answer questions and solve your problems. Many suppliers employ former tu rf managers

to market their products: therefore, they can relate to your situation.

The Ohio Turfgrass Conference & Show is a leader at helping turf managers grow profession-ally. Educational sessions are developed with input from OTF committee members, the O hio

Chapters of the GCSAA, Ohio Lawn Care Association, Ohio Sports Turf Managers Association,

and the Ohio Sod Producers Association.

The trade show boasts more than 250 exhibiting companies. Make sure you spend plenty of

time on the show floor establishing relationships with the exhibitors who are there to help you.

And dont forget about networking. OTF has added a new welcome reception on the show

floor this year. There are annual meetings and awards banquets to attend. Wednesdays reception

and auction provides ample oppor tunity to make con tacts and meet n ew friends. For some, net-

working at conferen ces is the most valuable asset th ey gain.

We hope to see you December 912 at the Greater Columbus Convention Center. Dont miss

this chance to grow in your profession. OTF provides a wealth of opportunities for education

and networking.
