LIME-SULPHUR MIXTURES FOR SUMMER SPRAYING. 13 
Plot 1, consisting of 40 trees, was sprayed with self-boiled lime- 
sulphur mixture made of 50 pounds of lime and 50 pounds of sulphur 
to 250 gallons of water (10-10-50 formula). 
Plot 2, containing the same number of trees as plot 1, was sprayed 
with self-boiled lime-sulphur mixture made of 30 pounds of sulphur 
and 30 pounds of lime to 250 gallons of water (6—6—50 formula). 
Plot 5, consisting of 20 trees, was sprayed with a factory-boiled 
or concentrated lime-sulphur solution at the strength of 1 gallon of 
the solution to 40 gallons of water. 
Plot 6, containing the same number of trees as plot 5, was. sprayed 
with Bordeaux mixture made of 2 pounds of copper sulphate and 
4 pounds of lime to 50 gallons of water. 
Plot 3, consisting of 20: trees, some of each variety, was left un- 
sprayed as a check. 
A block of about 100 trees, including all varieties, designated as 
plot 4, was sprayed by Mr. Aldrich with a proprietary mixture, 
which did no more good than so much water, and this furnished an 
additional check. 
RESULTS OF THE TREATMENT. 
The trees were examined and photographs made on June 19—about 
a month after the date of the first application. From 75 per cent to 
85 per cent of the leaves of the unsprayed trees and of the trees in 
plot 4 had dropped, and most of the remaining leaves were quite 
badly spotted. A photograph of one of these trees (Montmorency) 
is shown in figure 1. This was generally true of all varieties, but the 
Early Richmond showed less injury than the others. 
Plot 1, which received the 10—10—50 self-boiled lime-sulphur mix- 
ture, showed almost perfect foliage on all varieties except the Wrage 
and the Ostheimer, which were in a dying condition from previous 
years’ attacks. A close examination showed that slight infections - 
had taken place on some of the trees, and it was surprising that these 
were not more extensive, owing to the occurrence of heavy rains, 
which had partly washed the mixture off. 
Plot 2, which received the 6—6—50 self-boiled lime-sulphur mixture, 
showed practically as good foliage as plot 1, but it could be seen by 
careful examination that recent infections were rather more exten- 
sive. From casual observation the foliage appeared to be perfect, as 
shown in figure 2, which is a photograph of a sprayed Montmorency 
_ tree made on the same date as the one in figure 1. 
Plot 5, which was sprayed with factory-boiled lime-sulphur solution 
(1-40), was in equally as good condition as plots 1 and 2. The foliage 
was almost perfect and no injury resulted from the use of the solution. 
Plot 6, sprayed with 2-4-50 Bordeaux mixture, was in the same 
condition as plot 5. The disease had been almost entirely prevented 
and no injury from the use of the mixture had occurred.
