Spy, Baldwin and Colvert. The orchard has been regularly sprayed 
and is worked with a disk harrow each year. Spotting of the foli- 
age by the mite has been recognized in this orchard since 1903. The 
Baldwins have been the most conspicuously infested of the varieties. 
It is stated that the attacks of the mite affected the growth of the 
trees and reduced crop yields. Kerosene and crude oil emulsions, 
made with whale oil soap and diluted with ten parts of water, were 
used for the treatment of the orchard, and about three gallons of 
spray were applied to a tree. The treatment was made on April 14 
with a power sprayer. The blister-mite was less numerous this 
year than in 1907, but.its work is still noticeable in many orchards 
in this vicinity. 
Results on mite. Following the applications of the oil emul- 
sions very little spotting of the foliage by the mite was noticed in 
the experimental block. It is intended to repeat this treatment this 
spring. 
EXPERIMENT NO. II. 
Conducted by Charles I. Herrington, Warsaw, Wyoming County. 
The orchard that was sprayed contains ten acres, and the principal 
varieties of apples are King, Baldwin, Russet and Greening. ‘The 
orchard is now tilled but a portion of it has been in sod until the 
past year. Spraying with bordeaux mixture has been practiced for 
three years. The mite made its appearance in destructive numbers 
on the trees in 1907. The Baldwins have shown the most spotting 
of the foliage and about forty trees of this variety in the lowest 
portion of the orchard have sustained considerable damage. Other 
varieties similarly located present. a much better appearance, so 
that it is believed by the owner that the unfavorable condition of the 
Baldwins is not to be entirely attributed to drainage. The trees 
were sprayed during the first part of April with a commercial prepa- 
ration of the lime-sulphur wash, and about one and a half gallons 
of this spray were applied to each tree. The blister-mite is be- 
coming more destructive in this community, especially in orchards 
that are not receiving careful attention. 
Results on mite— The applications of the lime-sulphur wash re- 
duced the amount of spotting of the foliage. The owner believes 
that spraying for successive years with this mixture will efficienctly 
control the blister-mite.
