When you spray, get a sprayer big enough—one that is adapted to your needs and that will do the work thoroughly. 
that gives a fine, foggy spray. Have the nozzle set 
at an angle with the rod by means of a 45-degree L. 
Use good sprayers, well equipped. Have every¬ 
thing in good shape before you start. You can mix 
the materials, if you want to; but if you have any 
doubt whatever that you might not get the mixture 
right, buy the ready-prepared lime-sulphur and 
bordeaux that needs only the addition of water to 
be ready for putting on the trees. Then follow the 
printed directions faithfully. 
HOW TO SPRAY APPLE TREES 
No. 1. For San Jose scale. This spraying can 
be applied any time after the leaves drop in the fall, 
until new leaves come in the spring. But it is most 
effective when applied just before the buds begin 
to push out in the spring. 
Use standard lime-sulphur solution, at a strength 
of one gallon to seven to nine gallons of water. 
(See manufacturer’s printed instructions.) If bud- 
moth and case-bearers are attacking the trees, mix 
three or four pounds of arsenate of lead with each 
fifty gallons of spray. 
No. 2. For apple-scab, canker-worm, bud-moth, 
case-bearers, tent caterpillars, curculio, and leaf- 
spot or frog-eye, spray after the cluster-buds open, 
and before the blossoms open. Use standard lim p- 
sulphur solution at a strength of one and a half 
gallons to fifty gallons of water, adding two pounds 
of arsenate of lead. If you want to make your own 
material, always. use self-boiled lime-sulphur for 
this spraying. It is made by combining eight pounds 
of lime and eight pounds of sulphur, with fifty gal¬ 
lons of water, in the way described in “How to 
Grow and Market Fruit.” Two pounds of arsenate 
of lead should be added to each fifty gallons of the 
mixture. 
No. 3. The main spraying is for codlin-moth 
(common apple worm), curculio, lesser apple worm, 
and the second is for scab, leaf-spot and all the other 
enemies mentioned under second spraying. Aside 
from the San Jose scale spraying, this is the most 
important one. Spray after most of the blossom 
petals fall, and before the blossom cup or calyx 
lobes close. Use either the commercial standard 
lime-sulphur solution at a strength of one and a 
half gallons to fifty gallons of water, together with 
two pounds of arsenate of lead, or self-boiled lime- 
sulphur and lead, strength mentioned before. 
No. 4. This is for added protection against 
scab, codlin-moth, lesser apple worm, curculio and 
leaf-spot or frog-eye. Apply the spray twenty to 
twenty-five days after the blossom petals fall. Use 
either commercial standard lime-sulphur solution, 
at a strength of one and a half gallons to fifty gallons 
of water, with two pounds of arsenate of lead, or 
the self-boiled lime-sulphur and lead. 
No. 5. This spraying is intended to control the 
second brood of codlin-moth, also to help control 
sooty fungus, leaf-spot and fly-speck. Apply it two 
months after the blossom petals fall. Use the same 
spray material you used for fourth spraying. 
SPECIAL ATTENTION SOME¬ 
TIMES NEEDED 
If bitter-rot and sooty fungus are bad, you must 
change spraying No. 5, and also give some later 
sprayings, as follows: 
No. 6. Two months after the blossom petals fall. 
No. 7. Two to three weeks later. 
No. 8. Two weeks later. 
No. 9. Two to three weeks later. 
Use bordeaux mixture, made by dissolving four 
pounds of bluestone in twenty-five gallons of water 
and four pounds of lime in twenty-five gallons of 
water, then mixing the two lots. To this add two 
pounds of arsenate of lead, except for sprayings 
8 and 9, which are made with the bordeaux only. 
If the weather is dry, the late sprayings may not 
be needed. In wet weather give them all. 
If apple-blotch threatens to be serious, as judged 
from former years, spray regularly at the same 
dates as noted, but instead of lime-sulphur solu¬ 
tion, use for sprayings 4 and 5 bordeaux mixture 
made from three pounds of bluestone, four pounds 
of lime and fifty gallons of water, with two pounds 
of arsenate of lead added. Also apply an extra 
spray, with the same material, six weeks after the 
blossom petals fall.
