Guelph; has released the
findings of ,a test program
conducted last 'summer to
determine the degree of ozone
damage which can be ex,
pected to, be sustained to
crops in Huron County.
According to Mr. Ormred,
sensitive crops such as white
bean, snap bean, radish,
' sweet corn, potato, soybean
and onion "would be exp,ected
to be injured by ozone
episodes".
'..`There is little doubt," the
report notes, "that ozone
concentrations in, Huron
County are quite frequently
higher than the threshold for
crop plant damage."
Last summer's program
was carried out using tobacco
plants as the test case. Seed
of four tobacco cultivars,
varying widely in ozone
sensitivity, were sown in flats
in a growth chamber at
Guelph.
Seedlings were tran-
splanted first to 10 -cm pots.
The cultivars used were Bel -
W3 (super -sensitive to
ozone), Bel -05 (sensitive to
ozone), Bel -BT (intermediate
sensitivity to ozone). .and
Delhi 34 (relatively tolerant
of ozone). Three plants of
each cultivar were planted at
each of six sitesin or near
Huron County, on June 16,
1976.
Ozone concentration was
monitored at Kippen, by the !
Ridgetown College of
Agrfeultural Technology
using a Mast ozone meterand
_recercier. from June 3 to
September 1976. The
record chart- was used to
determine daily high and low
ozone concentrations. A
number of ozone episodes
occurred during the recor-
ding period, There were 37..
days with an ozone peak
conkentration of 8.0 pphm or
highr. The. principal
episodes occurred in lune,
early July and late August.
The period from July 27 to'
August 19 had loK ozone
levels except for August 3 and
4. The ozone analyzer records
indicate that ozone injury to
sensitive species would likely
occur several times during
the growing season in Huron
County, four on July 29 or
Aug. IL Bel -BT was injured
only at sites one to three but
generally not at sites four to
six. The tolerant Delhi 34 had
slight injury on July 14 and 29
at site.
• The substantial leaf injury
on June 30 was probably the
result of elevated at-
mospheric ozone con-
centrations which continued
daily from June 23 to 30. The
lower injury on Bel W-3 at all
sites on July 14 compared to
June 30 was associated with
generally much lower ozone
levels during the previous 10
days, Many of the injured
leaves present on June 30
would be dead or abscised by
July 14 and would thus not be
included in the damage
estimate. Similarly leaf 'in-

However,
This sketch map of Huron County shows th,e six test sites
where the effect of ozone contamination was measured
on tobacco plants set out by D. P. Ormrod of the
department of Horticultural Science at the University*
Guelph. Number one is the tam of Adrian Vos near
Blyth, two is the farm of John Hazlitt in Cidbortle
Township, three is the farm of Phil Durand north of
Grand Bend, four is the farm of Harry Kniplust over the
county line in Middlesex County, five is the farm of Bob
Allen near Brucefield and six the farm of Nick White
near Seaforth.
• Meetings of all kinds are being held on the farm front
this time of Year, so many that it is difficult to keep
abreastiof what is going on. ,
For instance. a name heard regularly for years in con-
nection with the old Ontario farmers union and now the
National Fariners„Union. has been defeated in hjs. afrek,
re-election to the post of vice-president.
That name? Why. Walter Miller. of course. the person-
able beef farmer from Tara insouthwestern -Ontario.
Walter is an old friend. I've said many times that he has
always had the..family farm in mind when he has made
his statements. No other person in the farmers union has
• fought harder and longer than Walter Miller for Ontario
farmers.
I maintained almost 10 years ago that the farmers union
made a mistake when they decided "Co go national" at a
provincial,convention in .Kingston. I felt at the time that a
blanket, national organization would wipe .out each prov-
ince's identity. yrn, afraid that is exactly what happened
when Walter was Ousted as vice-president at the annual
meeting in Edmonton.,
Walter is at home,. putting his feet up, resting after 25
years of farm union activity. Knowing Walter, I'm sure
he won't remain out of the limelight long. I understand his
voice is already being heard in beef associations. He runs
a beef feedlot himself. Watch for' him to becomeinstru-
mental in seeking a better deal for farmers in beef mar-
keting.
Another name which has been widely -acclaimed in farm
circies for a dozen years is that of George McLaughlin..
the articulate dairy farmer from Beaverton, who stepped
down This month after ;seeing the Ontario Milk Marketing
Board through a tremendously. turbulent. — but .success — decade. George has also said,he plans to retire to
his farm andlisten to the Milking.inachin,es but I find
that difficult to accept, too.
And yet another: Gordon Hill. the past -president of the

Ontario Federation of Agriculture: Gordon stepped down

Again, - on t think Gordon writ be able to'ait still long.
I suspect residents of the Varna area will see his name
_ on a ballot one of these days.
Getting back to Walter Millet-, I admire his loyalty.
He has fought for the farmers union for a quarter of a
century. He never made it as national -president and *Ss •
content to live in the shadow of big Roy Atkinson, the ,
Prairie farmer. All kinds of rumors have been circulating
in farm circles about considerable unrest and dissension
within tEe union. Yet, after he was defeated, Walter re-
fused to comment disparagingly about his union comrades.
He could have been bitter andvindicative. Instead, he
has played the • part of gentleman and statesman. All he
said was that "there's a lot of soul-searching going on in
the NFU.- '
Finally, a comment on these annual meetings abundant
during the winter months in farm circles.
As a reporter for more than 20 years on various news-
papers and a couple Of radio stations, I still maintain that '
farmers are the warmest, friendliest'people in all of Can-
ada. The United Co-operatives of Ontario meeting in Tor-
onto early in December' asked •this writer to be a guest
speaker at the, wind-up banquet. They lived up to their
name. I have never been treated -so warmly and had more
co-operation than 'I did during my brief visit with. UCO.
Allen Macintosh, president, and his friendly, 'outgoing
wife made my wife and I feel right at home during the
banquet and afterwards.
As long as farm organizations of all kinds can entice
men such as Al Macintosh to accept exectitive positfons,
then these farm nrganizatioris are in good handk
