should throw finely divided mist,
and be set at an angle TO the rod, In |
order to facilitate covering the under
surface Of the leaves II the pump will
support a pressure Of 40 pounds
when four nozzles are in use, "Y"
connection and two nozzles for each
extension afford an effective means OF
applying the spray.
Experience has shown that the field
roads used at harvest time may be
advantageously kept open during the
growing season for passage of the
spray machine, Boys may be employ
ed to support the hose and prevent
dragging of the vines. Rough treat
ment will knock off blossoms and
small fruit, thereby reducing the Yield.
Dates and Number Of Applications
AS the occurrence of the diseases Is
largely dependent on time and amount
of rainfall 1t is difficult to recommend
a set schedule for spraying melons,
For average conditions, three appllca-
lions are suggested Spray for the
first time when the plants have been
out of the ground about two weeks. A
hand pump Of the knapsack type is
most convenient for this application
The second spraying may be given
when the plants have developed
good system of runners. The third
spraying should be given about two
weeks before maturity. If rainfall is
heavy and disease prevalent, an adj
ditional spray should be given seven
to ten days later.
Such schedule merely suggests a
set of applications that might be eff
fective in an average season. In case
dry weather prevails during the grow
ing season, the second application
nay be delayed until two weeks be-
fore maturity. If rains are frequent
at this time, make another applica-
ton in about seven to ten days. In
stances have been known where
spraying would have paid even though
the loading season was well under
way. Heavy rains and continued moist
weather at any time during the season
should be the signal for the applica
ton of Bordeaux mixture. If possible,
the application should be made a suf-
fcient length of time before rain to
allow the mixture to dry thoroughly
on the leaves. The best time to spray
is in the morning on bright, sunny
day.
CarleSS Work Useless
Owing to the method of doing the
work, much spraying done on the
farm accomplishes little more than
waste of time and material. Halfway
measures are useless in spray work.
AS a rule the work is left to ignor-
ant laborers who proceed with the oh
ject of covinfg as large an acreage as
possible in a limited amount of time
portion of each plant may be
sprinkled under these circumstances,
but this is not sufficient. Spraying
that will control fungous diseases
means more than that. The spray
solution acts only as preventive, and
the ideal application is one in which
every leaf of the plant is covered, top
and bottom, with finely divided mist.
Unless this is done, disease may get a
foothold in the field, and the POSSIBLE
ity of control will be doubtful.
Spraying Cost Compared to Return
In a spraying demonstration on a
24-acre field in Georgia in 1917. the
total cost for each application was
found to be "a cents an acre. Yield
records kept in connection with a
spraying experiment in the same To-
cality in 1917 showed that the differ
ence in returns from a thoroughly
sprayed plot and nearby unspray-
ed plot amounted to $3.50 an acre.
After deducting the cost of three APP
plications. 1882. the profit derived
from spraying in this instance
amounted to $16.6S an acre.
