From the President's Corner

By Dick

Schmidt

W h a t goes on behind the closed doors of a board
meeting? W h y don't they do this or do something
about that?
I remember when I was a regular member of the
N. T . A. and sat around in a friendly group and heard
criticism after criticism about any and everything, as
' I am sure you do. W e all know that it's human nature to criticize, and also very much a part of human
nature to just sit back and do nothing. Just think
• how great an organization would be if just half of
the membership would get themselves involved. W h y
don't you as a membr of the N. T . A. step forward
to help your own cause and get involved?
Our '72 conference at Ocean Shores, as you can
see by the enclosed program, should be a great one.
W e have some new and unusual topics as well as
some oldies with new approaches.
The second equipment, product and display show
will be a great one. W e have arranged the show right
in the middle of all activities, with an emphasis on
keeping ther members and the displayers as close as
possible. I am sure you will be pleasantly surprised at
this unusual arrangement.
The golf tournament will be Tuesday, September
26th at the Ocean Shores Golf Course. Don Pupera
will be running the competition with lots of super
prizes. Be sure and bring your straight ball as this
course will challenge the best.
Mrs. Blair and her committee on the ladies entertainment program has done just a super job setting
up activities for the ladies in attendance. Be sure and
tell your wife to join us at Ocean Shores this year
and to be ready to have a good time. I am sure she
will.
I hope you have all received appropriate information
about this year's conference. If any of you have not
for some reason or other, please drop a card to Roy
Goss or myself and we will get the necessary information to you.
I am looking for ward to seeing you at Ocean Shores.

To the Ladies Attending the
Northwest Turfgrass Conference
By Jackie

Schmidt

Dick and I are most anxious for you to come and
enjoy yourselves at the conference at Ocean Shores
the end of September. W e promise you a busy time
as a full program has been arranged for your pleasure. You are urged to participate in these planned activities which will still allow you plenty of leisure
time for shopping, beach combing, horseback riding,
just to name a few of other things to do at Ocean
Shores.
Wednesday mid-morning will find us playing "Human bingo," followed by lunch at the beautiful Golf
Course Dining Room. Golf clothing is in order as a
nine-hole "Fun Golf Tournament" has been arranged
for after lunch. No handicaps needed; just a few clubs,
and a couple of golf balls. Anyone can win this one,
so do participate. There will be plenty of time for a
rest before the banquet Wednesday evening at Ocean
Shores Inn.
Thursday about 10:30 A.M. we will gather for a
scenic tour up the coast and then to Lake Quinault
Lodge for a sumptous luncheon and educational entertainment, followed by a choose-your-own walk
through the beautiful rain forest. Transportation will
be arranged for you. This is a most interesting trip
which will culminate back at Ocean Shores about
4:00 P.M.
Tuesday and Friday are free time to do your own
thing. W e have been informed that September is one
of the more beautiful months at Ocean Shores. Wearing apparel is informal . . . knit suits, slack suits,
slacks and sweaters, and long skirts or cocktail attire
for the banquet. However, just in case the unusual
should occur, have available a wind scarf, rain gear
and proper footwear to insure your comfort.
Don't miss this conference, do come and be prepared to have a grand time.

SECOND ANNUAL PRODUCTS AND
EQUIPMENT SHOW AT CONFERENCE
By Ron Proctor
This year's N.T.A. Equipment and Products Show
will again be held in conjunction with the annual N.
T.A. conference September 26-29 at the Ocean Shores
Inn.
The Ocean Shores Inn has the best to offer in exhibit facilities. The Equipment and Products Show will
be held in the Shore Room. The Shore Room is located adjacent to the meeting rooms and registration
area, making it very accessible to everyone.
Last year's exhibit generated a great deal of interest
among the orofessional turfgrass managers, as well as
the exhibitors themselves. Due to this interest, all available booths have already been reserved, and with more
exhibitors and more viewing time this year's show promises to be biaaer and better than ever.

Tim Manion, from Columbia - Edgewater Golf
Course, is in the process of building new tees and cart
paths. Bill Martin, from Agate Beach Golf Course,
has recently completed two new tees on the Agate
Beacli Course. Bill Neussle, Superintendent of Charbonneau Golf Course, has completed the front nine
and they will play in October. He is presently working on the back nine.
John Slaughter is presently grading on the Sommerville Golf Course, King City Number Two. Jerry
Bacon from Royal Oaks is now playing on some new
tees, which he has been working on. Dick Malpass, at
Riverside Golf Course, has been doing some additional
tile drainage work on cart paths.
Jerry James has completed a new 18-hole course
near Battleground, Washington and Gerritt Gerson
is the golf superintendent.
John Monson, former golf superintendent of Corvallis Country Club, has recently accepted the superintendents' position at Broadmoor Golf and Country
Club in Seattle. Corvallis Country Club is presently
accepting applications for Golf Course Superintendent. The salary is open plus fringe benefits. Anyone
interested in this position should contact Dr. Bill
Paul, Jr., President, Corvallis Country Club, 1850 S.
W . Whiteside Drive, Corvallis, Oregon 97330. The
correspdondence should be marked "personal".
The Golf Course Superintendent's Association of
America has announced the appointment of a new
executive director, Conrad L. Scheetz. Mr. Scheetz
has a Bachelor of Science Degree in Commerce and
Engineering from Drexel University in Philadelphia.
He has had considerable experience in data processing and has already included a comolete redesign of
the accounting structure with GCSAA and has placed
it on data processing equipment.
The Executive board of the GCSAA will meet in
Portland, Oregon for its annual fall Board of Directors' Meeting. This is the first time ever that the
GCSAA Board has met in the Pacific Northwest.
They will, no doubt, be considering the possibility
of the Northwest for future G C S A A conferences.

When you
work for a company
like Scotts, you have a
lot to live up to.
100 years experience in helping make turf grass
greener and healthier, for example. Leadership in the
development of seed, fertilizer and control products.
ProTurf products for fairways, greens, tees and
aprons that cost less to buy, are cheaper to apply, and
guarantee satisfaction. And a reputation for solving
problems wherever turf grass is grown.

As your Scotts Technical
Representative, I'd like to share
Scotts most current turf grass research
and development information with you. With this information,
perhaps we can work together toward meeting
vour turf grass objectives.

United States Golf Association,
Green Section, Grants
By Roy L.

Goss

The United States Golf Association, Green Section,
for many years has supported turfgrass research at
various locations and institutions around the U.S.A.
In the past the USGA made many smaller grants so
that more areas and research people could benefit from
them. It has been determined, more recently, that
rather than make a large number of small grants it
was more productive to make a fewer number of larger grants.
The Green Section has further determined that their
research fund should be placed in areas that have projects with the greatest yield potential in terms of research productivity and information that will serve the
greatest number of people. They further desire to place
their funds with research units with the greatest potential to solve specific problems and produce good research. For example, research on Bermuda grasses can
best be supported in the states with the greatest use
of that type of turf and with the problems that are
most prevalent.
This year, the U.S.G.A. Green Section awarded a
grant of $1000 each to the Agronomy and Plant Pathology program at the Western Washington Research
and Extension Center at Puyallup, Washington. This
$1000 grant each, will continue for a period of three
years. This will make the total input from U.S.G.A/s
program to Northwest research $6000 over the next
three years.
The financial grant willl be used by R. L. Goss in
the Agronomy program to further sulfur studies of
turfgrasses. Besides the quality effects of sulfur on
tuff grasses other information as follows will be gained:
1. The effect of sulfur on Poa annua.
•2. The effect of sulfur on algae conrtol.
3. The effect of sufur on soil pH.
4. The effect of sulfur on the amino acid and protein content of turfgrasses.
5. The effect of sulfur on nitrogen metabolism in
turfgrasses.
Some of the laboratory tests involved in analyzing
these data are quite expensive and the $1000 per year
for the next three years will be the making of the results of this sulfur study.
The $1000 annual grant to the Plant Pathology
program will be used primarily in a large bentgrass
varietal study aimed at determining if bentgrass varieties are resistant to Fusarium oatch disease caused by
the fungus Fusarium nivale. This program is headed up
by C. J. Gould, Plant Pathologist at the Western
Washington Research and Extension Center Gould
has accumulated varieties, selections, and breeders stock
from all over the world for this study. At the present
time there are over 103 entries, which include 61 seeded types and 42 stolonized types. These plots are established for the most part, with some of the stolonized
varieties still developing at this time. The fall of 1972
will yield the first information regarding varietal resistance and the next two years, 1973 and 1974 will
yield valuable information. Gould and Goss will cooperate on this project to develop as much information
about these grasses as possible. In addition to the disease resistance, Goss will obtain data such as color
factors, textural factors, density, aggressiveness, and
response to treatment.

Final Notice for
Annual
N.W. Turfgrass
Meeting
Your president, Dick Schmidt, has issued three announcements up to now regarding the Turfgrass Conference, including dates and location. Ron Proctor,
chairman of the Product and Equipment Display Show
has likewise pointed out the dates and events.
The Board of Directors and the Program Committee
feel that we have a very well rounded and interesting
program for the meeting at Ocean Shores this September. Although the conference proper will not begin until 1 P.M. on Wednesday, September 27, there
will be plenty of activity beginning on Tuesday, September 26. Take this extra day and come early to enContinued on Page 5, Col. 1

joy a little relaxation and to tcehnically bring yourself
up-to-date with Produces and Equipment that the displayers will be showing. It is equally important to keep
yourself informed of new products and new equipment as it is to keep up with research technology. These
Product and Equipment Displays are designed for this
very purpose of introducing you to new materials and
ideas. At these Product and Equipment Shows, you
have an opportunity to informally chat with Company
representatives about their products or equipment and
to ask questions that may be on your mind. These
people are very happy to discuss any of their ideas
or yours at this time.
W e have a varied program including several interesting subjects and many good speakers, as you will
see in the program itself which you will find on oages
2 and 3 of Turgrass Topics. There has been some definite progress made in Poa annua pre-and post-emergent control and we plan to have an informal twohour session on Thursday afternoon to discuss this
subject in depth with a many reearch people from the
11 Western states as we can induce to stay for this
session. Researchers from the 11 Western states will
meet on Tuesday and Wednesday morning preceding
the turf conference to coordinate all of the turfgrass
research that is occurring in the 11 Western states.
Some of these fellows will have to return home before
Thursday, but we hope to have enough of them left
to conduct a very informative session. W e also intend
to call on certain Turfgrass managers, who have practiced Poa annua control to sit in with these researchers
on this panel.
The Ocean Shores Conference site was selected because of ample facilities and a peaceful and tranquil
setting for a real educational conference. The only
thing there to distract ones thoughts is the peaceful
roar of the' breaking surf and the temptation to get
out on the golf course. W e are sure you will all enjoy
the conference, so get your reservations in now. You
can obtain room reservations by calling Seattle, MA
3-2111 or writing directly to Ocean Shores, P.O. Box
82, Ocean Shores, Washington 98551.

The Future of Phenoxy
Herbicides as Weed, Brush Killers
By Roy L.

Goss

Herbicides classed at "Phenoxy" type are those
such as 2,4-D; 2,4,5-T; 2,4,5-TP, etc. These herbicides
have performed effectively and safely on cropland and
noncropland in the United States for more than 20
years. The need for these materials is clearly evident,
likewise, the need for caution and safe use is obivious
as well.
In an article by Dow Chemical Co., in their publication "Down to Earth", published in the spring of 1972,
it was indicated that the E P A (Environmental Protection Agency) has taken a more relaxed attitude about
2,4,5-T and other related Phenoxy herbicides. They
indicated that the teratogenic effects (deformed or
monster animals) can only be caused by dosage levels
far in excess of any possible exposure.
The U.S.D.A. states that prohibiting the use of
Phenoxy herbicides "would cost the U.S. farmers an
additional 290 million dollars to maintain current agricultural production. In addition, farmers and their
families would have to work 20 million more hours to
control the weeds without these herbicides. For the
extra labor, the farmer would obtain no additional
income."
The article further ooints out that over a million
dollars has been expended over the past two years to
prove the safety of Phenoxy herbicides to man and his
environment. From a scientific base, the Phenoxy herbicide can contribute economically, efficiently, and safely in the future for the control of broadleaved weeds
and brush, on food crops, pasture, range land, and
non-cropland areas as they have for many years up
to now.
It is easy to damn and condemn chemicals from the
ecologic viewpoint, but it is a little more difficult to
come up with facts regarding the hazards of chemicals. It is interesting to note that a recent report indicated that the brown pelican on the California coast
have had the largest hatch in 1972 that has occurred
in many years. D D T was possibly the chief factor
claimed by the ecologists for the decline of the brown
pelican. I leave you with one question. Is it possible
that through the restricted uses of D D T in scarely
one year, that the environment could be so cleaned up
that the brown pelican is on the increase again? Is
it not possible that through some evolutionary cycle,
that the brown pelican was on its way out anyway?

Western Regional Coordinating
Council on Turfgrasses Meets
Meets at Puyallup, Ocean Shores
By Roy L.

By Jim

Chapman

The latest Western Canada Turfgrass newsletter
"The Turf Line News/' carried an article by R. A.
Broome answering a question on . . . the greatest task
in maintaining sportsfields. His comment was . . .
"drainage, soil used, lack of funds to install adequate
drainage systems."
How true! Whether athletic fields or golf courses.
The funds expended on design, irrigation, buildings
seem to disappear as construction reaches final stages.
Thus, the stages that suffer most often are those most
visible as the new golf course develops—drainage, soil
mix, sprinkler head locations.
George Gumm, while Superintendent at the Ocean
City (Md.) Country Club, once said, "All you have
to have for a good golf course is good drainage and
common sense. If you're low on common sense, double
up on drainage."
The grapevine has new golf courses starting soon
in Seattle, Port Ludlow, Cle Elum, Vancouver, Washington; Ashland and Biggs Junction, Oregon; at least
two near Vancouver, B.C.; one at Big Mountain, Montana.
Dick Rose took his Rainier Country Club experience, earned under Ron Proctor, to his new position
as Superintendent of the Sage Hills Golf Course in
Warden, W A . He replaced Bond Harmon, new Superintendent at Kah-Nee-Ta, the Warm Springs Indian
Resort golf course.
Interesting—the articles on the importance of sulfur
in various trade magazines. Dr. Fred Grau has authored several, including one in "Better Crops with
Plant Food." He expounds on the value of potassium
sulfate as a S source and quotes research reports of . . .
who else? . . . Goss and Gould. Look for more as research on the value of S continues.
If compaction—thatch—silty soil is still giving some
problems, remember the long wet winter just past. It
helped complicate already tough turf maintenance conditions. Fortunately, new machines (triplex mowers
with thatching reels, fast topdressers and aerifiers)
are also available—if at a cost—to help speed and
ease Che work. Come, look at these at Ocean Shores.
You'll never see a better display locally. See you there!

Goss

The first Western Washington Regional Coordinating Council of the 11 western states will meet at
Puyallup, Washington beginning Sunday, September
24, 1972. Representatives from institutions conducting
turfgrass research from the 11 western states and the
three western provinces of Canada (Saskatchewan,
Alberta, and British Columbia) will meet to discuss
turfgrass research programs which are being conducted
in this region. The principle aim of this council is to
bring together this group for a free exchange of ideas
and an effort to better coordinate the research being
conducted.
Regional Coordinating Councils have functioned for
many years through the Agricultural Experiment Stations in various agricultural pursuits. It has proven very
effective in developing a better direction for research
for various crops. Research people endeavor to keep
in touch with what is going on throughout the world,
but with a vast amount of literature being published
and work being done, it is nearly impossible for any
one individual to keep abreast of the entire program.
It is obvious that through all researchers, different
ideas and approaches are constantly being employed.
Through these council meetings we may save many
man years of futile attempts by eliminating the duplication of effort.
This first meeting on turf was organized by Dr.
J. D. Rogers of Colorado State University at Fort Collins, Colorado. He conceived and promoted the idea
with all research institutions in the west. The idea
was enthusiastically received by all turfgrass researchers and this first meeting is the result of his efforts.
Puyallup was chosen for the first meeting by the majority of persons responding since there is a turfgrass
conference planned at a suitable time where this group
can attend and participate.
The group willl assemble near Puyallup on Sunday
evening, September 14. On Monday morning ,September 25, there will be a brief tour of turfgrass research and the turfgrass industry in the Puyallup area.
From there the group will move to Ocean Shores by
Monday evening to begin formal sessions on Tuesday
morning. The delegates will be in session until Wednesday noon, at which time the Turfgrass Conference
will convene. If additional time is necessary, the conference can continue until the business is completed.
W e are looking forward, with a great deal of interest to this first meeting and to the great potential
of this type of coordinated effort.

Expanded Studies on Typhula
Snow Mold Control
In Eastern Washington
By Roy L.

Goss

Throughout the years, Typhula snow mold occurs
with variable intensity. Some years are good snow
mold years and others are practically free of the disease. The standby materials for treating turfgrasses
attacked by Typhula incarnata have been phenyl mercury and a mixture of mercuric and mercurous chloride
(calo-calor). More recently, new materials aopearing
on the market indicate good potential Typhula control.
Dr. D. K. Taylor, from the Canada Department of
Agriculture Research Station at Agassiz, B. C., has
conducted several trials in the colder interior of British Columbia and has obtained variable results between locations. He found no one material to be totally effective in all three of his test locations. However,
some very interesting results occurred from his trials.
The trials to be conducted in Eastern Washington
will be coordinated with Dr. Taylor's efforts and expanded to include various combinations of materials
and timing factors. Bud Ashworth, of Hangman Valley Golf Course at Spokane and Johnny Harrison of
Hayden Lake Golf and Country Club at Hayden Lake,
Idaho, have volunteered research areas for these trials
for 1972. It is anticipated that these trials will be initiated beginning in early fall. Results of these trials
will not be known until spring thaw.
Fusarium patch control will be worked into this
study to determine the severity of this disease in early
. fall and early spring. A suggested program will be
provided to all persons in the snow mold region who
may wish to try some of the new materials upon request.

Plots have been established and materials are being
collected by C. J. Gould for Fusarium patch control
trials in the fall of 1972. With the changing role of
chemicals being what it is, one never knows from year
to year what may be prohibited by the EPA. W e must
constantly seek new materials for the control of Fusarium so that we may stay ahead and not be caught
in the position we were 25 years ago. Results of these
trials will be published at the end of the application
season.

Progress on POA ANNUA
Control-PrePost-Emergence
By Roy L.

Goss

W e arc not trying to talk this weed to death but
wish to keep you informed of any progress being
made.
Pre-emergence trials on putting greens have been
conducted at the Western Washington Research and
Extension Center since May of 1970. These plots have
received continued chemical treatment for 2-1/2 years
and some of the information should be passed along
to you. Bensulide and tricalcium arsenate are only two
basic chemicals being employed for the pre-emergent
controls, since others have been eliminated. These materials are being applied with various combinations of
fungicides. The fungicides merely control Fusarium
patch so that we may determine if disease is one of
the principle factors determining the invasion of Poa
annua into bentgrass turf.
In summary, August evaluations indicate that a single
application of Bensulide annually at 15 pounds per
acre active ingredient' either by itself or in combinations with fungicidal treatments still maintains an undesirable level of Poa annua in the plots. Records
taken for the last three years indicate that there has
been a reduction in the total Poa although the average still remains about 22 percent Poa in the plots.
Plots treated with Bensulide on the basis of 12 pounds
active ingredient per acre with 3 pounds per acre additional being applied every 3 months has reduced
Poa annua to the degree of only a trace or no observable plants being found in any of the plots.
Tricalcium arsenate applied to achieve a level
of* 18 pounds of product per 1000 sq. ft. in one year
has reduced the Poa annua population to no observable plants in the plots, regardless of fungicidal treatment.
Where fungicides were applied alone with no preemergence treatment, the plots contain an average of
33 percent Poa annua.
There were only slight color variations among the
treated plots at the time of this evaluation. Earlier in
the season, plots treated with tricalcium arsenate, had
considerably reduced color over the other plots. At
the time of this rating, the tricalcium arsenate plots
rated slightly better in color than all others.
In regard to density, the greatest turf density was
obtained where no pre-emergence treatment was applied. From the August evaluation the following densities were estimated: one annual treatment with Bensulide produced a 9.85 average density out of a possible 10. Reoeat application of Bensulide yielded an
average density of 8.5 out of 10. Plots treated with
tri-calcium arsenate average 6.5 density out of a possible 10. Plots treated with fungicides without preemergence average slightly better than 9.5 and the
check plots averaged 8.3.
In summary, there is no question that the pre-emergence herbicides Bensulide and Tricalcium arsenate
will control Poa annua if applied properly to the proper
soil and grass conditions. These studies are not entirely conclusive at this time and these treatments are
not necessarily recommended. No conclusion should be
drawn from these studies until at least one more year
of data have been accumulated and root studies have
been completed.

The effects of sulfur and other nutritive elements
on Poa annua development will be reported in the turfgrass conference proceedings under the research section, so will not be discussed in this article.
Pot-emergence control plots of Poa annua were established in August, 1972 and information regarding
any effective treatments will be published in future
articles in Turfgrass Topics. As a matter of interest,
those of you who read the article in the Golf Supertendent in the August-September issue should take a
word of caution that the chemical Kerb should not be
used at all or with extreme discretion on bentgrass
turf. Your editor has tested this material over three
years ago and found that the material has an extremely narrow range between selective control and phytotoxicity to bentgrasses. It is very fortunate that this
material is working so successfully on Bermudagrass,
however, Dr. Horn pointed out their specific technique in this very well conducted experiment.

EXPANDED STUDIES ON OPHIOBOLUS
PATCH DISEASE IN TURGRASSES
Recent findings on some of the factors affecting
Ophiobolus disease in cereals by R. James Cook, indicate that some additional trials for the control of
Ophiobolus patch in turf should be pursued. The cooperative project between G. J. Gould and R. L. Goss
is currently being initiated. Plots where these trials
will be conducted have been fumigated with methyl
bromide and planted to Highland bentgrass. It is known
that turfgrasses established on soils fumigated by
methyl bromide are attacked to a higher degree by
Ophiobolus patch than on soils non-fumigated. More
recently, Dr. Cook has learned that soils from areas
free of Ophiobolus patch disease on wheat can be
moved to Ophiobolus infected sites and help to overcome the disease. This technique as well as a number
of other nutritional and chemical approaches will be
investigated in these trials.
