SPRAYING FRUIT TREES.

Bulletin No. 10, Delaware College
Experiment Station, treating of "Ex-
periments in the Treatment of Peach
Rot and of Apple Scab," is out. It is
an interesting number. All these
bulletins can be had by addressing a
card to the Agricultural Experiment
Station, Newark, Del.
No.19 gives very interesting data and
tables of tests and experiments in
spraying fruit trees. We quote the
general directions for spraying peach
trees:
l. During the winter or very early
in the spring remove from the trees all
mummified fruit; gather and burn the
same.
2. Very early in The spring it will
be well to spray the trees thoroughly
with solution of copper sulphate (blue
stone), one pound of blue-stone to
t~ ~enty-five gallons of water.
8. When the fruit buds begin to
swell spray either with the Acetate of
Copper solution or the Bordeaux mix
ture
4. Just before the fruit buds open
repeat the latter.
5. When bloom begins to shed spray
~ with Paris green 3 ounces to the
barrel of water Ito this add about a
quart of whitewash, milk of lime); or
~ with Bordeaux mixture to which is
added, to each barrel of the latter, 8
ounces of Paris green.
6. In 10 days or two weeks repeat
the latter.
Z. When fruit just begins to color
spray with the Copper acetate solution.
s. Repeat the latter in a week or
ten days.
In preparing the Bordeaux mixture.
especial stress is to be laid on the ad-
vantage of preparing beforehand a
barrel of strong blue stone solution,
made so that each gallon of the solu-
tion will contain say two pounds of
blue stone.
1t is great advantage to buy the
blue stone coarsely pllverized, as in
this form it dissolves so much more
rapidly. In this condition and with
hot water, large quantity of con-
solution of the blue stone
can be made very quickly.
1t is also well to have another barrel
filed with slaked lime or whitewasb,
BY slaking given quantity of lime
for each barrel of the Whitewash, pro-
vided the same is well stirred, it will
be easy to tell about what weight of
lime is in each gallon of the whitewash,
and thus the necessary quantity can be
readily added by measure.
In spraying use nozzle which gives
Il misty spray, wet every part, but
drench none.
1t is better to spray on cloudy or
partly overcast day, or when the sun is
not too hot, thus the foliage is less apt
to be Injured.
The experiment upon peach tree |
were made by Mr.J. W. Killen, FELTON,.
Mr.. S. II. Derby, Woodside. made
similar experiments with apple trees,
and the following general directions.
are given for that work:
Regarding the cost of spraying ap-
pies. Mr.. Derby has estimated it, for
material and labor. at about ten cents
per trees for Eve srrayings.
This is exactly the cost as determined |
for peach trees. So far as my own OBJ
seryations 60 / do not think that the
cost need ever exceed Is cents per tree,
and believe that It can be done for as
low as 10 cents, if all fruit growers
will provide themselves with the labor
saving appliances found on Mr.. Derby,s
place.
Mr.. Derby has his copper previously
and in solution of known
while his lime is similarly
as already recommended. A
boiler provides him with steam for
heating water, and AN elevated tank
gives an abundant supply Of cold
water. He is thus able e, mix
quantity Of fungicide very quickly.
The best pump and nozzles and ex-
perienced labor enables him to work
quickly. and do twice as much as AMI
ordinary operator. who Is making a
can do in the same time.
In spraying apples We would recon-
mend the course pursued BY Mr. Derby
q this experiment. Use The Bordeaux
mixture. For the drst application
which should b msde IS scon as the
