38 SPRAYING PEACHES. 
benefits. The trees at Baldwin, Ga., were sprayed with a good hand 
outfit, and 3 men were able to spray 1,000 trees a day. With labor at 
75 cents a day (the wages paid in that section), arsenate of lead at 10 
cents a pound, sulphur at 23 cents a pound, and lime at $1.10 a barrel, 
the cost for three treatments was $27.60 a thousand, or a little less 
than 3 cents a tree. At Fort Valley, Ga., a gasoline-power sprayer 
was used. The trees there were larger and the water was not so con- 
venient, making the cost somewhat higher than at Baldwin. In this 
‘ase the cost of three treatments was $32 a thousand, or a little more 
than 3 cents a tree. Where wages are higher the cost will be some- 
what greater. For three treatments, the first with arsenate of lead 
alone, the second with self-boiled Lme-sulphur and arsenate of lead, 
and the third with self-boiled lime-sulphur alone, the cost will range 
from 3 to 5 cents per tree, depending upon the labor conditions, the 
size of the trees, the convenience of the water supply, and the equip- 
ment used. For average-sized 7-year-old trees, as a rule 1 gallon 
of spray per tree will be required for each application. In the first 
application not quite so much will be required, owing to scant foliage 
at that time, while a little more will be required for the second treat- 
ment. The third application should be lighter than the second, 
using finer nozzles so as to avoid staining the fruit with blotches of 
lime. 
From the experience of the writers it seems safe to conclude that 
in most of the peach orchards of the eastern United States an increase 
per tree of at least one-half bushel of good merchantable fruit, worth 
about 50 cents, may be obtained from spraying at a cost of 3 to 5 
cents. Spraying, therefore, is the most profitable of all the orchard 
operations. 
SCHEDULE OF APPLICATIONS. 
Most of the peach orchards in the eastern half of the United States 
should be given the combined treatment for brown-rot, scab, and 
curculio. This is particularly true of the southern orchards, where 
all these troubles are prevalent. In some of the more northern 
orchards the curculio is not very troublesome, but as a rule it will 
probably pay to add the arsenate of lead in at least the first lime- 
sulphur application. 
The self-boiled lime-sulphur mixture referred to in the following 
outlines of treatment should be made of a strength of 8 pounds of 
lime and 8 pounds of sulphur to each 50 gallons of water, and the 
arsenate of lead should be used at the rate of 2 pounds to each 50 
gallons of the mixture or of water. When the poison is used in 
water there should be added the milk of lime made from slaking 2 
to 3 pounds of good stone lime. When used in the lime-sulphur 
mixture additional lime will not be necessary.
