SPRAYING CALENDAR. 
Phis calendar, in a concise way, gives our friends the benefit of the many experiments made by the Agricultural 
Colleges of the country for a number of years. It is believed they can be followed without danger to the crops and 
with much profit to the grower. 
The number of applications given in each case has particular reference to localities in which fungous and insect 
enemies are most abundant. If the crops are not affected at the time advised, the spraying is unnecessary. Know 
the enemy and the remedy, and apply them at the proper season, keeping in mind the fact that good judgment and 
prompt and persistent action is more necessary to success than any definite rules. 
The applications to which an asterisk * is prefixed are of most importance.

First Application, 
When buds are swell- 
ing, copper sulphate solu¬ 
tion. 
♦When worms or aphis 
are first seen, Kerosene 
emulsion. 
♦When rust is first 
noticed, Bordeaux. Ker¬ 
osene emulsion when red 
spider is first seen. 
As buds are breaking, 
Bordeaux; when aphis 
appears, Kerosene emul¬ 
sion. 
♦At first sign of worms, 
Arsenites. 
♦When leaves expand, 
Bordeaux. For worms, 
as above. 
In spring when buds 
swell, copper sulphate 
solution. ♦Paris green for 
flea beetle. 
♦When first leaves 
appear, Bordeaux. 
♦Before buds swell, cop¬ 
per sulphate solution. 
As buds are swelling, 
copper sulphate solution. 
♦During first warm days 
of early spring, Bordeaux 
for black knot. When 
leaves are off in the fall, 
Kerosene emulsion for 
plum scale. 
♦Soak seed for scab in 
corrosive sublimate solu¬ 
tion (a oz. to 16 gals, of 
water) forgo minutes. 
Before buds break, cop¬ 
per sulphate solution. 
Cut out badly diseased 
canes. 
For mildew. ♦Keep 
heating pipes painted 
with equal parts lime and 
sulphur mixed with water 
to form a thin paste. 
♦As first fruits are set¬ 
ting, Bordeaux. 
At first appearance of 
blight or rot, under glass 
or outofdoors,Bordeaux. 
Second Application. 
♦Just before blossoms 
open, Bordeaux. For bud 
moth, Arsenites when leaf 
buds open. 
7-10 days later, if not 
heading, renew emulsion. 
♦For rust repeat first in 
10-14 da} s. For red spi¬ 
der repeat in 3-4 days. 
When fruit has set, 
Bordeaux. If slugs ap 
pear, dust leaves with air- 
slaken lime. Hellebore. 
♦iodays later. Hellebore. 
If leaves mildew, Bor¬ 
deaux. 
*10-14 days later, Bor- 
deaux. For worms, as 
above. 
♦When leaves are 1-1 
inches in diameter, Bor¬ 
deaux. Paris Green for 
larvae of flea beetle. 
*10-14 days, repeat first. 
Before flowers open, 
Bordeaux. 
♦Just before blossoms 
open, Bordeaux. Kero¬ 
sene emulsion when 
leaves open for psylla. 
♦When buds are swell¬ 
ing, Bordeaux for black 
knot and other fungous 
diseases. During mid¬ 
winter, kerosene emul¬ 
sion for plum scale. 
♦When beetles first 
appear, arsenites. 
During summer, if rust 
appears on leaves, Bor¬ 
deaux. 
For black spot. *Spray 
plants once a week with 
Ammoniacal copper car¬ 
bonate, using fine spray. 
As first fruits are ripen¬ 
ing, Ammoniacal copper 
carbonate. 
Repeat first if diseases 
are not checked. 
Third Application. 
♦When blossoms have 
fallen, Bordeaux and Ar¬ 
senites. 
*7-10 days later, if head¬ 
ing, hot water 130° F. 
Repeat second, using 
the Ammoniacal carbon¬ 
ate of copper if plants are 
in bloom. 
10-14 days ifrot appears, 
Bordeaux. 
1 f worms persist, Helle 
bore. 
*10-14 days later, Am¬ 
moniacal copper carbon¬ 
ate. For worms, as 
above. 
♦When flowers have 
fallen, Bordeaux. Paris 
Green as before. 
io-i* days, repeat first. 
♦When fruit has set, 
Bordeaux. 
♦When blossoms have 
fallen, Bordeaux and Ar¬ 
senites. Kerosene emul¬ 
sion if necessary.

fallen, Bordeaux. Begin 
to jar trees for curculio. 
Before buds start, Kero- 
sene emulsion for plum 
scale. 
♦When vines are two- 
thirds grown, Bordeaux. 
Arsenites for beetles if 
necessary.

sary. 
For red spider. *Spray 
lants twice a week with 
erosene emulsion. Ap¬

age.

Repeat second as before 
if necessary. 
10-14 days later, Am¬

ate.

*S-i2 days later, repeat 
third. 
*10-14 days later, Bor-

culio every 2-4 days. For 
San Jose scale, Kerosene 
emulsion when young ap¬ 
pear spring and summer.
