BUFFALO BISONS OPEN IN NEW PILOT FIELD

For years, the Buffalo Bisons fought offembarrassment in what they admitted wasone of the worst stadiums in the country,War Memorial Stadium. Nevertheless, morethan a half million fans came to see the AAAAmerican Association baseball team lastyear.

This spring the team will play its homeopener in the pride of Buffalo, Pilot Field,a new 19,000-seat stadium built with $30million of state, local and private funds thispast year. Bob Rich, owner of the Bisons,hopes to double attendance in the new fa-cility and set a new record for minor leaguebaseball. Rich and 84 other investors paid$1,000 each to save the 100-year-old fran-chise in 1979. Rich took over the team in1983.

HOK Sports Facilities Group designed thenew stadium to blend in with the architec-ture of historic downtown Buffalo. "Pilot Fieldfollows the tradition of Ebbets Field, WrigleyStadium and Comiskey Park," explained Ben

Barnert, project architect. "It looks like it hasbeen part of Buffalo since day one." Topreserve tradition on the field, the new stadi-um also has natural turf.

Rich said the stadium is, "the cornerstonefor a downtown turnaround." It is locatedless than two blocks from a recently com-pleted mass transit terminal and sharesnumerous parking facilities with the WarMemorial Auditorium. Part of the turnaroundcould be a Major League Baseball expan-sion franchise. In that case, a third deckwould be added to Pilot Field to increaseseating to 40,000.

Pilot Field has all the amenities of MajorLeague stadiums. HOK included 38 luxu-ry boxes, a 3,50o-seat club level, completepress facilities and computerized score-board. The die-hard bleacher fan also has1,000 seats to choose from in right field."Pilot Field is a downtown stadium designedso that all Buffalo sports fans can enjoy base-ball in comfort," remarked Barnert.

OHIO SUPERINTENDENTTAKES SKINS AT PGAWEST

Steve Blackburn, superintendent at Bri-ardale Greens Golf Club in Euclid, OH, firstthought club professional Fred Schnellerwas kidding when he asked him to be hispartner for the USF&G National Pro-AmSkins Game competition. They had playedtogether in a number of pro-am events, butnever anything as big as this. As the pairwon a local round and made the final cutat TPC of Sawgrass in Ponte Vedra, FL,Blackburn got psyched. The next stop wasPGA West in La Quinta, CA, to play on thesame course and at the same time as JackNicklaus, Lee Trevino, Arnold Palmer andFuzzy Zoeller.

Blackburn and Schneller continued to daz-zle the television audience as they foughtfor the lead, winning more than $19,000 inskins. Victory was in their grasp, but itslipped away in the final moments. The pairhad to settle for second place. Blackburn,an amateur, had the experience and $400in prizes to take home to Euclid, an easternsuburb of Cleveland.

During an interview on ESPN, Blackburnpraised the course and urged other superin-tendents to find the time to playas manycourses as they could. "I try to look at mycourse as a player first and then as a su-perintendent," he stated. "The more a su-perintendent plays, the more he'll appreciatethe game of golf and what the player seeson his course." After playing many topcourses all over the country, Blackburn start-ed keeping his greens at Briardale "reallyfast." He believes the greens challenge thegolfer to concentrate on his putting just asa scratch golfer does.

LEITERS FROM READERSA SHOW FOR ALL SPORTS TURF MANAGERS

40 Years of Experience

As a Class A member of GCSAA for nearly40 years, and having attended many GCSAAConference & Trade Shows, beginning withthe 1937 show in Washington, DC, whenmy dad (Lester Hall) was a speaker, I f~elI am qualified to answer your Front Officecolumn in the January 1988 issue of sport-sTURF magazine.

I am sure GCSAA members as a wholefeel an acute kinship to any and all managersof intense use turf. I have seen in my morethan 50 years of experience in turf manyof the changes and the progress in the theturf management field that both you andDenne Goldstein wrote about in this issue.Hard work, a quest for knowledge, desireto improve one's self, renewing old acqua.in-tances, making new ones and the desireto be able to present to his employers thelatest in equipment and supplies, has madeGCSAA's International Turf Conference andTrade Show the greatest assembly of turfmanagers, educators and exhibitors in t~efree world. To my knowledge, no one, In

any area of turf management the world over,has ever been denied permission to attend.

Turf professionals assembled from theworld over have attended and I have hadthe priviledge to have met and spoken withthem over the years. These have all addedto the outstanding qualities of the truly In-ternational Turf Conference & Trade Show.Since its humble beginning in 1926, GCSAAhas led the field in the advancement of high-quality turf. Not just for golf, but i~ all ~reasof turf, including sports, cemeteries, riqhts-of-way and home lawns.

The past few years, other professionalturf managers have been invited to partic-ipate as well as conduct their own educa-tional segment of educational programs. Asconsultant to the Collier County SchoolBoard for their athletic fields, I had theprivilege to attend some of the ~essions inboth San Francisco and Phoenix. Those Iattended were very informative, excellent-ly presented and well-attended by manyother golf turf managers.

I have never heard a member-at-Iarge orboard member say anything negative aboutour fellow professionals attending sessionson golf turf management. Those in fieldsof like endeavor must help themselves tothe opportunities presented. To malign o.urboard and membership in this manner IS,

to say the least, un sportsman like. Intere~tand hard work are the keys to success Inany endeavor.

The years of success of GCSAA's Inter-

national Conference and Trade Show aredue to these ethics; not only by the board,the show committee, and member partici-pation, but also our fine staff of headquarterpersonnel. The efforts put forth by ~IIof ~heseand the years of experience gamed In 58years of presenting the show shoul~ c~~-tainly entitle GCSAA to remain the signifi-cant sponsor of the show.

I feel the answer lies more in the next tolast paragraph of your article rather thanany of those preceding. Are these other 0[-ganizations willing to accept GCSAA sleadership along with the heading, "GCSAAPresents The International Turf Conferenceand Trade Show?" I feel GCSAA members,board and staff have been more than gener-ous by making its presentation op~n. to allwho are sincerely interested and Willing towork to make the show even larger, betterand more educational.

After all, the show and conference hadvery humble beginnings and if allied profes-sional organizations wish to compet~ rath~rthan join our presentation, that IS theirprivilege. The exhibitors are tho~e wh? ~ustsuffer the most in making multi-exhibits oftheir wares to those of very similarprofessions. .

Every turf professional manager IS orshould be aware that an opportunity suchas GCSAA's Turf & Trade Show exists, andif they desire to be better, all they have todo is register and more importantly, AT-TEND. With such a combined attendancethe exhibitors would gain by not only larg-er attendance, but fewer shows. With thissavings in costs, they more than lik.elycouldmake their participation and exhibits bet-ter and even more educational.

An Obligation to ShareThe Musser International Turfgrass Foun-dation and the National Sports Turf Coun-cil, with lots of help, unlocked the door andopened it a crack. In your editorial you kickedthe door wide open and sent the blockerssprawling. It is wonderful to see the futurethrough an open door.

Those who have the power to raise fundsfor research and education are morally ob-ligated to share for the good of all who areinvolved and doing the right things withoutbias-seeking only to serve those who needit the most. No longer can one segmentstand aloof displaying riches beyond meas-ure while another impoverished facet of theindustry suffers from neglect.

Working Together Is All That Counts

The purpose of the Front Office columnin the last issue was to bring the industrytogether. I hesitated mentioning GCSAAboard members at all. Anyone who devotesthe time and energy to be a board mem-ber deserves only thanks, not criticism. Fromwhat I've heard, these board members arejust trying to protect the confere~ce.

All that matters is that we recognize eachother as teammates, not opponents. If a fewmembers of the sports turf market gain spe-cial status, it should be their pleasure to helpothers do the same.

CHALKBOARD,..,TIPS FROM THE PROS

RESEARCH REVEALS ACCELERATED BREAKDOWN OF PESTICIDES

Evidence is mounting that microorgan-isms living in thatch are causing some highlyeffective insecticides for soil pests to breakdown rapidly after repeated use. Dr. HarryNiemczyk at Ohio State University's Agricul-tural Research and Development Center inWooster, OH, suspects that poor late-summer control of grubs (scarabaeid bee-tle larvae) is being caused by biodegrada-tion of insecticides in the thatch as opposedto ineffectiveness of the insecticides in thesoil. He further suspects that this phenome-non is not limited to certain insecticides andin the future may be linked to poor perfor-mance of some herbicides and fungicides.

Niemczyk started looking into the problemwhen turf managers in Ohio, Massachusettsand New York reported isolated cases ofpoor control of grubs during late summerfollowing a spring application of Oftanol, aninsecticide known for season-long controlof turf-damaging soil insects. Something hadto be changing in the thatch and/or soil af-ter repeated application of the insecticide.

He started combing the literature for rea-sons to explain the insecticide's decreas-ing performance in sporadic instances. Oneby one, he considered application timing,inadequate posttreatment irrigation, disrup-tive management practices, any unusual cli-matic factors and insect resistance. Hequickly instituted laboratory tests of thatchand soil samples taken from golf coursesexperiencing poor late-summer grub control.

Niemczyk, with the help of Dr. R. A. Chap-man, an entomologist at the Canada Depart-ment of Agriculture Research Center, Lon-don, Ontario, discovered that when a knownamount of isofenphos, the active ingredientin Oftanol, was added to thatch and soil sam-ples taken from the problem courses, it wasrapidly broken down. When the sameamount of insecticide was added to thatchand soil from previously untreated sites, itdid not break down. Niemczyk obtained thesame results in field tests last year. The cul-prit was something in the thatch and soilof previously treated turf, not insectresistance to Oftanol. Niemczyk suspect-ed that microorganisms in the thatch andsoil were breaking down the insecticide be-fore it had a chance to control the grubs.

Previous studies had shown that microor-ganisms can adapt to the presence of a pes-ticide to the point of being able to use it asa source of energy, degrading the pesticidein the process. These tests also revealedthatthe population of these microorganismswas higher in the thatch than in the soil.34 sportsTURF

"We have not directly linked microorgan-isms to the breakdown of insecticides in turfyet," says Niemczyk, "but something in thethatch and soil is breaking them down, inless than a week's time."

"We (Niemczyk and Chapman) proposethat microorganismal adaptation to residuesof isofenphos concentrated in the thatch isthe major reason for the noted reductionin the residual effectiveness of isofenphosto control summer infestations of scarabaeidlarvae," said Niemczyk. "It doesn't appear

Niemczyk suspectedthat microorganismsin the thatch and soilwere breaking down

the insecticide.that this accelerated breakdown is limitedto long-residual insecticides. It may well in-volve short-lived insecticides as well as her-bicides and fungicides. It's important tostress that the problems we've seen so fardo not apply everywhere. The rule of thumbshould be, if a compound works, use it."

However, if a pesticide you have usedrepeatedly for two or three years is notproviding the same control it did original-ly, accelerated degradation, not insectresistance, may be the problem.

Until more conclusive evidence is ob-tained, says Niemczyk, the turf managercan try alternating pesticides and manag-ing thatch to reduce the potential for ac-celerated degradation. Once a turf areaadapts to degrade a particular insecticiderapidly, it maintains its ability to break downthe compound for years. Furthermore, thereis no practical way to completely removethatch - nor is it desirable.

Niemczyk has found that as much as 95percent of the residues of many commonly-used insecticides applied to turf remainsin the thatch even after watering-in. He hasalso shown that most grub control takesplace at the thatch/soil interface where thelarvae consume organic material (thatch,tillers, and rhizones) treated with insecti-cide. "The fact that the residues are in thethatch is not all bad," he states.

The biggest problem to developing a curefor accelerated degradation is that microor-

ganisms do not always react in a logical pat-tern, explains Niemczyk. Logic would sug-gest that if the majority of the microorgan-isms reside in the thatch, reducing theamount of thatch could possibly reduce thepotential for accelerated pesticide break-down. This would suggest that a programof thatch control, including aerification,proper mowing intervals, turfgrass selec-tion and avoiding excessive fertilization,could reduce the potential for accelerateddegradation. While complete removal ofthatch is impractical, keeping the thatch layerunder control might also permit more insec-ticide to reach the soil where it can possi-bly last longer.

Niemczyk has also been researching themovement of pesticides applied to turf. Sofar, tests of eight different insecticides haverevealed that thatch traps much of theresidue, even after posttreatment irrigation.These same insecticides applied directly tosoil move into the top two inches depend-ing largely on their solubility in water.

AMMONIUM SULFATEBOOSTS HERBICIDEPERFORMANCE

Recent studies by a University of Nebras-ka weed specialist for Monsanto Corpora-tion have shown ammonium sulfate im-proves the control of annual grasses andbroadleaf weeds by glyphosate, a nonselec-tive postemergence herbicide. Glyphosateis the active ingredient of Roundup andLandmaster herbicides.

"Ammonium sulfate can counteract theeffects of unfavorable weather conditionswhich tend to make weeds more tolerantto herbicides," says Dr. Fred Roeth, weedspecialist at the South Central Research andExtension Center of the University of Nebras-ka. Roeth explains that ammonium sulfateimproves the absorption of glyphosate byplants.

In similar field trials conducted by Mon-santo, ammonium sulfate improved controlof annual grasses by up to 25 percent andcontrol of broad leaf weeds by up to ten per-cent. "It all depends on how far from op-timal weather conditions are in a given year,"stated Monsanto's Dr. Neal Hageman. Herecommended that landscape managers inareas of unpredictable weather add 17pounds of dry ammonium sulphate to ev-ery 100 gallons of spray solution.

John Deere engineers have developeda medium-size vacuum sweeper for turf andgrounds applications. The model 141 sweep-38 sportsTURF

er collects debris through a 48-inch widevacuum scoop and stores it all in a 1.4-cubic-yard hopper. An impeller compacts thedebris by flattening cans, shredding leavesand paper, and pulverizing bottles. A greatdeal of debris can be stored in the 141 'shopper before it's necessary to dump theload.

The vacuum sweeper is powered by a 16-hp gasoline engine with a 10-gallon fuel tankand has an impeller speed of 3000 rpm. Italso includes a vacuum pick-up hose forhard to reach areas. The vacuum scoop ispositioned in front of the pneumatic tiresat the widest part of the machine forthorough cleaning of areas where it's difficultto maneuver. It also has an optional filtra-tion system that helps prevent sand lossfrom the hopper.

Deere recommends that the model 141be drawbar-mounted to a towing tractor withat least 20 PTO-hp. For ease in dumping,the vacuum has a spring-loaded, self-unloading rear gate. It also has a steera-ble jackstand for convenient hookup.JOHN DEERECircle 131 on Postage Free Card
