18 THE CONTROL OF APPLE BITTER-ROT. 
until the trees came into bearing, or about twelve to fifteen years. 
Then the land was usually left uncultivated. A portion of it, includ- 
ing the experimental block, is now in sod, having been seeded to 
orchard grass in 1902. 
According to Mr. Goodwin, bitter-rot first appeared in this orchard 
to a noticeable extent in 1899, and in 1901 it did considerable damage. 
In 1903 the trees received three early applications of Bordeaux mix- 
ture, and on September 13 of that year the writer visited the orchard 
and roughly estimated the loss from bitter-rot at 40 per cent. When 
the crop was harvested, a few days later, Mr. Goodwin estimated the 
loss at about 60 per cent. Since 90 per cent of the crop was lost in 
some unsprayed or-

were included in the experiment. They are 19 years old and about 25 
feet high, with a spread of about 25 feet. These trees have been 
pruned by thinning out the conflicting branches, and have developed 
into the broad, low, somewhat pyramidal type naturally assumed by 
this variety. The block is situated below the middle of the orchard, 
with 23-year-old trees of the same variety on the east and a young 
orchard not yet in bearing on the west. Below (north side) is a block 
of young bearing trees of the same variety, the crop of which, not 
being properly sprayed, rotted badly. On the upper side is a block 
of young trees not ye in bearing. |
