Raspberry Anthracnose. 
In the spring of 1§94 a communication was received from Mr. 
S. A. Hosmer, of Clifton, New York, in regard to anthracnose on 
raspberries and kindly offering the Station the remains of his once 
large plantation to use in experimenting with treatment for the 
disease. was | 
The plantation at one time consisted of 25 acres and was re- 
garded as producing one of the most paying crops of the farm; but 
through the ravages of anthracnose the acreage was yearly reduced 
until now scarcely three acres of badly infested plants remain. 
Seemingly every cane was diseased, immense scabs and blotches 
from four to eight inches in length and reaching nearly around the 
cane were not uncommon. The present plantation, consisting 
entirely of Gregg, was set out in the spring of 1890; it comprises 
about three acres of gravelly loam situated on a gentle southern 
slope. The rows, 50 in number, run north and south. 
Puan oF THE EXPERIMENT. 
Primarily the experiment was undertaken to see if the disease 
could be successfully combatted ; secondarily, different solutions 
were used for the first treatment, so that a comparison might be 
made as to their effectiveness in treating the disease. 
Knowing that a remedy for any fungus disease must be pre- 
ventive rather than a cure, and that fungi begin their work very — 
early in the spring, it was planned to give the first treatment 
before the leaf buds opened; at this time strong solutions could 
be used as there would be no foliage to be injured; accordingly 
the rows were treated as follows: The first three with copper 
sulphate, three pounds to 11 gallons of water; the next three 
with a saturated solution of iron sulphatein water, while the next 
three were reserved for checks. This plan was carried on 
throughout the plantation, except the last two rows, making in 
all 18 rows treated with the copper sulphate, 15 rows treated with —
