76 SPRAYING— PEAR— PEACH— PLUM— SMALL FRUITS 
Pear Spraying 
This system is practically the same as for the apple. However, as 
mentioned in the first part of this chapter, it is not always necessary to 
follow out a complete system each year. (Spraj-ing wiU not help the fire 
blight. It requires special treatment. See page 38.) 
First Spraying. Early spring or winter, before the buds open, use 
boiled lime-sulphur for San Jose scale, oyster-shell scale, scurvy scale, 
psylla, and pear leaf blister mite. 
Second Spraying. Just before the blossoms open, use Bordeaux mix- 
ture 3-3-50 and arsenate of lead 3 pounds for scab, leaf spot, leaf-eating 
insects, and leaf blight. 
Third Spraying. This should be made just after the petals of the 
blossoms fall. Use Bordeaux 3-3-50 and arsenate of lead 3 pounds for 
scab leaf blight, leaf spot, leaf-eating insects, and the codling moth. 
This is especially designed against codling moth, and the spray should be 
directed under high pressure into the open calyx cups of the blossoms. 
Fourth Spraying. Ten days to two weeks later, use the same spray 
materials as in the tnird. This is for the control of the same insects and 
fungous diseases as in the third. 
Peach Spraying 
The system of spraying peach is somewhat different from that of 
apple. Never use Bordeaux mixture on peach trees in the summer, as it 
is very apt to kill the leaves. Use self-boiled lime-sulphur when the 
trees are in leaf. 
First Spraying. The first spraying should be done during the winter, 
before the Duds start to swell in the spring. Use concentrated lime- 
sulphur wash (see page 79). This is for the peach leaf curl, scab, and rot. 
Do not use it after the buds start to swell. The lime and sulphur will burn 
them. When the leaf curl is widely spread, this application should be 
made in the early spring, just before the buds swell. 
Second Spraying. The second spraying should be made about the 
time the shucks, or calices, of the fruit are dropping off. Spray with 
arsenate of lead 2 pounds and quicklime 2 pounds to 50 gallons. This is 
for the eurculio. 
Third Spraying. Two weeks later, or about a month after the petals 
drop, spray with 8-8-50 self-boiled lime and sulphur and 2 pounds of 
arsenate of lead. This is for the brown rot, scab, and also the eurculio, 
which help to spread the brown rot. 
Fourth Spraying. About one month before the fruit ripens, use 
8-8-50 self-boiled lime and sulphur. This is for the brown rot and scab. 
(See page 72 for directions for preparing spray materials.) 
Plum Spraying 
For plums, use the same materials and system as recommended for 
the peach. Never use Bordeaux mi.xture on Japanese plums, such as 
Abundance, Burbank, and Red June, as it sometimes injures the foliage. 
Spraying Small Fruits 
Currant and The system of spraying currant and gooseberry as out- 
n ^^^aUa^^r-ir lined is complete, but it is seldom necessary to make all 
ijooseoerry ^j^^ applications. 
Spraying First Spraying. Before the leaves open in the 
early spring, use boiled lime-sulphur. This is for San Jose scale, scurvy 
scale and oyster-shell scale.
