378 Report OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
EXPERIMENT NO. I. 
This experiment was undertaken by H. B. Vincent, Old Chatham, 
Columbia County. The orchard includes 30 acres, planted to 1200 
trees, which vary from 3 to 14 years of age. The lead- 
ing varieties are Baldwin, Spy, Greening, Oldenburg and Boiken 
apples and Bartlett pear. The older trees are systematically sprayed 
with the bordeaux mixture and the orchard is tilled and grown 
in grass in short rotation. The blister-mite has been present in con- 
spicuous numbers in the orchard for one year, when the Baldwins 
were most affected. It is not believed that important injuries were 
sustained by the outbreak. An application of the lime-sulphur 
wash was made on March 18, and about five gallons were used for 
each tree. The blister-mite is reported to be not very injurious to 
apples in this community. 
Results on mite.— The applications of the lime-sulphur wash in 
this experiment proved very efficient, and with slight exceptions 
the foliage was entirely free of injuries by the mite. 
EXPERIMENT NO, 2: 
This experiment was conducted by Berlin H. Wright, Penn Yan, 
Yates County. The orchard, of 4 acres, contains 100 Baldwins 
which are 20 years old. ‘The usual spraying with the bordeaux 
mixture is practiced. The larger portion of the orchard has been 
tilled, and the foliage and fruit have been so superior to that of 
the untilled trees, that hereafter the entire planting is to be given 
thorough cultivation. Extensive spotting of the foliage by the mite 
occurred last year for the first time. The owner believed that the 
injuries to the leaves caused some fruits to drop and reduced the 
size of the mature apples, and thus lessened the crop yield. The 
trees were sprayed with the lime-sulphur wash in March and again 
in April. The mite is reported as increasing in destructiveness in 
this community. 
Results on mite-—— The applications of the lime-sulphur wash 
were very effective. No pimpling of young apples was detected 
and the foliage was practically exempt from spotting by the mite, 
EXPERIMENT NO. 3. 
Conducted by B. J. Case, Sodus, Wayne County. The orchards 
comprise about 25 acres, planted to 640 trees, which vary in age 
from 26 to 55 years. The principal varieties are Baldwin, Green-
