br more to hear the lectures by ex

Considerable disappointment wa.
elt because three of the scheduled
speakers could not be present, bu
Expressions were general at the close
bf the meeting, late in the afternoon
hat the day had been most profitable
10 every one present because OF the
nass of information pertaining to
best and disease control and to sol
handling that was given out.
The speakers who were unable tC
ZONE were d. F, Fisher, plant pathOl.
bgist; John Peters. practical orch.
hrdist and expert on thinning, and M
!. Dean. secretary of the State HOrti'
tural Association.
However, one of the most instructive
papers was that prepared by Mr.
Fisher and read by p. s. Darlington
healing with powdery mildew and its
control.
S. p. Scott. horticultural inspector
presided at the meeting and Mr.. Dar-
lington, and Roy Larson, soil expert
were the two scheduled speakers
while Mr.. Simpson. manager OF the
government experimental farm at o.
liver, b. c., also spoke.
The speakers were followed atten-
3tively throughout and the deep inter-
lest aroused by their talks was man.
Infested by the numerous questions
asked by many growers in the audi
ence following each discussion.
Among the more important point
brought out and pressed home were
the necessity of building up and
mainta!ning soil fertility through the
use of cover crops, particularly alfalfa
in the orchards. with striking chart
showing the value of alfalfa hay In an
Orchard as compared to its present
value f. o. b., the cars; the necessity
for fighting powdery mildew and blis-
termite the time for spraying; meth
ods of irrigating, and how to get high
production and best quality of fruit.
The essential points in Mr.. Fishers
paper, as read by Mr.. Darlington,
were that powdery mildew has come
4 to the Northwest to stay and, if not
fought vigorously, orchadists may ex-
/ pect curtailment of production and an
/ increase in low grade fruits with
consequent lessened value of ORCH
ards. Three and possibly four spray.
ings are necessary to prove effective
4 in combating this disease. Lime
sulphur sprays should be used pro.
pOrtioned about one to 80. The times
for mildew spraying were given as
pink, second, calyX spray in combi-
nation with lead arsenate for codling
moth, third special mildew spray
applied about two weeks after the
calyx and possibly a fourth following
two weeks later. which would be the
first cover spray for the codling moth
as we'll. 1t is well to substitute am.
mOniacal copper carbonate at this
time and for the later sprays. if spray
ing Is to continue throughout ho,
weather. In ordinary seasons the first
three sprays should give fairly good
commercial protection.
Thoroughness as well as timeliness
was stressed as important in the fight
leaf should be covered. In order to
insure thoroughness the use of casein
spreader is advised. THE following
formula for the home preparation of
this spreader is advised: casein (use
none coarser than so mesh) one
pound; baking soda, three ounces
cold water one gallon. Stir all togeth-
er until casein is dissolved. One OF
two quarts of this mixture to 200 gal.
Ions of spray. For foliage spray, one
quart is effective, but after midsum-
mer more casen is required. This
should be used in day or two after
mixing, otherwise a disinfectant must
be added.
Another and a better formula was
said to be three ounces Of caustic soda
or ordinary household lye. one gallOr
of water, bring to boil then add one
pound of casein slowly sitting into
the lyewater while stirring to proven
Jumps forming. In either case do no
add more lye or baking soda than alb
solutely necessary or injury will re
suit
In winter pruning mildew shoots
and terminals should be cut out. Thi'
will not entirely eliminate the diseas,
but will lessen the work through tn,
use of spray.
Pears are more affected by mildev
than other fruits.
Powdery mildew is cumulative il
its effects, gradually becoming NOR
severe If not controlled The effect o
spraying is also cumulative, seasons
consistent effort in pruning an,
spraying always bringing marked re
suits in the way of control and max
ing the work easier the next year.
