SUGGESTIONS MADE
FOR MOTH CONTROL

TUX MUM IUNlkUI
The general program as suggested
for moth control work at meetings
held Saturday of last week and the
first three days Of this week, is al
follows:
Application of the calyx spray ii
all cases. In the main, or course, this
application had been made previous tc
these meetings.
Use of at least five meth traps to
the first ten acres with additional
traps used in larger orchards to de-
ternine actual situation as far as moth
flight is concerned in various parts Of
the orchard and the orchard as whole.
Traps should be checked daily and
this check continued throughout the
season. According to Mr.. Starcher
their work has shown that Diamalt
diluted with ninteen parts of water
to one of Diamalt has given best re.
suits. Cider or molasses may be used
The information gained from these
traps by each individual grower should
be checked against information put
out by the Horticulture Department
covering three to four orchards in the
community. Information gained from
the use of traps should be preliminary
to examination of the orchard for eggs
of the moth. And the application of
the spray based upon the finding and
condition of the eggs. During the first
two cover sprays when eggs are laid
in the upper parts of the trees and
upon leaves it is almost impossible to
locate them, hence these sprays should
be put on closely following the calyx
spray. Recommendations by Mr.. Deav-
er was to the effect that these three
sprays calyx and the first two covers
should be applied within a twenty
day period and this is in keeping with
recommendations Of the Extension
Service and the Horticulture Depart
ment made late in the winter.
The use of the summer oil as a
means of moth control for destruction
of eggs is highly recommended. The
time at which the oil should be used
will be determined by heavy moth
flight followed by location Of freshly
laid eggs upon the fruit. Meetings are
going to be held later under the sup
ervision of the Big Y organization TO
which all growers are invited, at which
Mr.. Deaver will point out eggs to
chose present so that they may be able
to indentify them and be better en-
abled to develop good spray pro-
gram at their own orchard. In the
main, we are holding to recommended
tons that not more than three oil
sprays be used during the season but
it may be necessary I'd use more I'M
der special conditions. and this has
been done in the past with out appar-
ent damage providing one does not
use an oil which is heavier than it is
recommended.
Discussion conferred around the con-
troll Of the worm largely by control
of the first brood. Norman Anglin of
Hanford mentioned several growers
of the White Bluffs and the Hanford
community who, during the season of
1928, had had some 20 per cent to so
per cent culls due to worms, who had
been able to control the situation last
season to the point that their loss was
from per cent to 10 per cent. Mr..
Anglin stressed particularly in his
discussion of more efficient operation
of spray machines, the application OF
plenty of spray and the operation of
the machine to secure somewhere
near the rated capacity of the machine.
He mentioned several growers who
were putting on what several of the
<hNtInl,t nat l.
possible; one man with thirty gallon
machine of 800 gallon capacity put on
rs tanks in day with the help OF
two men. Another man worked alone
who with IL gallons per minute and
200 gallon capacity had put on Is to 16
tanks per day. The question came up
as to the efficiency of such rapid
spraying, which Undoubtedly does
mean the wasting of some material.
However this question is simply one
of balancing cost of labor against cost
OF material ard if less is lost from extra
material wasted than is saved by the
least time given to the spraying work
then this would be justified. These
men spraying at the above rates have
been able to control worm infestation
to high degree of efficiency and
largely through spray program dur
ing the first period.
1t would seem. with examples of
good control secured last year by
individuals throughout the County in
orchards where loss had been heavy
the preceding year and with the new
information made available this year
through the work of Mr.. Spuler and
information coming to us from Mr..
Beaver and the Horticulture Depart
ment, that there can be no excuse for
fruit growers having serious loss
from the worm problem this year.
The program required for success de-
ponds largely upon the individual
growers knowledge of the actual stu
alton in his orchard and therefore
places the responsibility upon the
grower himself. Opportunity has been
given to the grower to enable him
to get this information and if he goes
through the spray season without hav-
ing this information we believe he will
find it much more difficult to control
the worm problem.
AS a general rule those who attend
the meetings are men who do not need
the help as much as many who do
not attend. We are going to urge, as
was done at the meetings, that every
grower who has neighbors who are
not using the best information, to en-
courage them to come, not only as
