380 Report OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
EXPERIMENT NO. 5. 
This was conducted by C. E. Taylor, Pulteney, Steuben County. 
The orchard comprises 3 acres, planted to 80 trees, which are 20 
years old. The principal varieties are Greening, Northern Spy, 
Baldwin and Wagner. The orchard is given the usual spraying 
with bordeaux mixture, containing an arsenical poison, and has been 
tilled for the past two years. Injury to foliage by the mite was 
recognized for the first time in 1906. Baldwins have been most 
affected. In 1907 the mite was reported to be very destructive, 
causing nearly all of the leaves to fall before the fruit ripened. For 
the treatments, miscible oil, diluted with fifteen parts of water, was 
employed, and about six gallons of the spray was applied to each 
tree. The treatment was made’on April 24, as buds were opening. 
Results on mite.— Spotting of the foliage by the mite was very 
much reduced. 
EXPERIMENT NO. 6. 
This experiment was made under the direction of H. C. Pratt, 
Canandaigua, Ontario County. The orchard contains I2 acres 
and has 450 trees, which vary from 33 to 50 years of age. The 
orchard consists largely of Baldwin, Greening, King and 
Russet. The trees have been regularly sprayed and for the 
past five years until this season, when cultivation was practiced, 
the orchard has been seeded to a mixture of vetch, clover and 
orchard grass. Attention was first attracted to the work of 
the blister-mite in this orchard in 1907 when the leaves were 
quite badly diseased. The Baldwins have been more affected than 
cther varieties. The foliage for this year was considerably in- 
jured and the fruit crop was small, but the owner reports that other 
factors had probably a greater influence in determining the yield. 
In the treatment of the trees a comparative test was made of the 
home-made lime-sulphur wash and a commercial preparation of 
this mixture. The treatment was made about April 15th and it is 
estimated that about eight gallons of either mixture was used to 
each tree. A power sprayer was employed to make the applications. 
The mite is reported as not gaining in importance in the vicinity of 
this experiment. 
Results on mite— Both the home-made lime-sulphur wash and 
the commercial preparation of this mixture completely held the mite 
in check. From the conditions of the foliage in both blocks, these 
sprays were equally efficient, and seemed in all respects satisfactory 
remedies for this pest.
