SPRAYING PEACHES. 23 
In the orchard of Mr. S. M. Marshburn, the demonstration treat- 
ment was given to 926 Elberta trees, 212 trees being left untreated 
for comparison. 
From the sprayed trees the yield was 209 crates of extra fancy 
fruit, 587 crates of fancy fruit, with 513 bushels, or 96 crates, of culls, 
the total merchantable fruit bemg 92.02 per cent. 
On the unsprayed trees the yield was 15} crates of extra fancy 
fruit, 1354 crates of fancy fruit, with 214 bushels, or 282 crates, of 
culls, the percentage merchantable being 84.02. 
In the A. O. Murphy orchard, the yield from 485 sprayed Elberta 
trees was 211 crates of extra fancy fruit, 272 crates of fancy fruit, 
with 684 bushels, or 914 crates, of culls, the total percentage mer- 
chantable being 84.09. 
On the 110 unsprayed Elbertas in this orchard the yield was 84 
crates of extra fancy fruit, 109 crates of fancy fruit, and 454 bushels, 
or 603 crates, of culls, the percentage merchantable being 66.07. 
In the orchard of Mr. A. M. Kitchen, at Baldwin, Ga., experiments 
and demonstrations were conducted on the Carman, Hiley, Elberta, 
and Summerour, or Atlanta, varieties, 2,000 trees in all being treated 
and a similar block left untreated. The trees were 7 years old and 
bore a fair crop of fruit, although the crop was rather light in por- 
tions of the orchard. The Elberta and Summerour varieties were 
sprayed (1) as the calyxes were shedding, April 7 and 8, with arsenate 
of lead, 2 pounds to 50 gallons of water; (2) on April 27 and 28, with 
8-8-50 self-boiled lime-sulphur and 2 pounds of arsenate of lead; 
and (3) on June 17 and 18, about a month before the fruit ripened, 
with 8—8—50 self-boiled lime-sulphur. The Carman and Hiley varieties 
received the same treatment, with the omission of the third applica- 
tion. At picking time the fruit from 5 to 11 sprayed trees and a 
like number of unsprayed trees in each variety was sorted and the 
results are shown in Table IV.
