New YoRK AGRICULTURAL EXPERIMENT STATION. 381 
EXPERIMENT NO, 7. 
This experiment was made by H. L. Bulkley, Brockport, Monroe 
County. The orchard embraces seven acres, planted to 300 trees 
which are 34 years of age. The varieties that are largely grown 
are Baldwins, Twenty-Ounce, King, Greening and Spy. The 
trees were not productive until 1896 when the owner commenced to 
spray and till the orchard regularly, and to apply fertilizers. With 
the exception of one year, good crops of fruit have been harvested 
annually. The blister-mite appeared in destructive numbers in the 
orchard in 1905, especially on the Baldwins and the Greenings, but 
less on the latter than the former. In 1907 the work of the mite 
on the fruit was noticed for the first time and about 10 per ct. of the 
crop was thought to be pimpled. The blister-mite was less abun- 
ant in 1908 than during the preceding year, but generally it is gain- 
ing in.importance in this community as an orchard pest. The spray 
used this year for the treatment of the mite was the lime-sulphur 
wash and only about two gallons were applied to each tree, the ap- 
plications being made on April 20-22 with a hand pump. Checks 
were left for comparison. 
Results on mite Notwithstanding the small quantity of wash 
employed there was an appreciable reduction in the amount of 
affected foliage on the sprayed trees. The foliage was not entirely 
clean, but the appearance of the treated trees satisfied the owner 
that a more liberal use of this spray in season would prove an 
effective remedy for this pest. 
EXPERIMENT NO. 8. 
The experiment was conducted by Wm. J. Edmunds, Sweden, 
Monroe County. The orchard contains about 15 acres and com- 
prises approximately 500 trees, which are about 34 years 
old. Many varieties of apples are grown but a large proportion of 
the trees are Baldwins. The farm has been managed by tenants, 
who have sprayed the orchard every year, and have endeavored to 
keep it well tilled. The trees have been productive. The blister- 
mite has been in injurious numbers in the orchard for the past 
three years and has been especially abundant on the Baldwins. 
Other varieties such as Ben Davis, Cooper Market and Bellflower 
have also shown more or less spotting of the foliage by the mite but
