340 REPORT OF THE COMMISSIONER OF AGRICULTURE. 
to suppose they will have a like action on the reproductive bodies 
in question. . ; 
Prepare the solution of hyposulphite of soda by dissolving 1 
pound of the hyposulphite in 10 gallons of water. Apply with a 
convenient force-pump having a spraying nozzle of fine aperture. 
The action of this remedy is immediate, hence it is necessary to 
apply it frequently during the season. 
The sulphate of copper solution with carbonate of soda (described 
on page 331), or the following solution of ammonia calcarbonate of 
copper may be useful in treating this disease: In 1 quart of liquid | 
gape dissolve 3 ounces of carbonate of copper, then dilute to 20 
gallons. . 
These preparations of copper salts should be applied in the same 
manner as the hyposulphite of soda solution. They adhere very 
strongly to the foliage, and as the copper they contain dissolves very 
slowly their preventive action against the fungus lasts for a long 
time. 
A solution of sulphide of potassium or ‘“‘liver of sulphur” has 
been employed in combating the blight of the strawberry with en- 
couraging results. Mr. R. HE. Buffum, of the University of Virginia, 
writes : 
I sprinkled the strawberry plants with a solution made by dissolving 1 ounce of 
sulphide potassium in 8 gallons of water, repeating the operation -several times 
before the berries ripened. This, I think, hada beneficial effect, as there was certainly 
a marked decrease in the amount of blight. 
Prof. J. C. Arthur states in the Sixth Annual Report of the New 
York Agricultural Experiment Station, page 351, that— 
A part of a bed of Sharpless strawberries was sprayed four times with a solution 
of sulphide of potassium (one-half ounce to 1 gallon of water) with the object of hold- 
ing in check the spotting of the leaves, due to the fungus Ramularia Tulasnet, 
often described as ‘‘sun-burn.” The object sought was attained, as that part of the, 
bed took ona more vigorous growth and showed fewer spotted leaves than the re- 
mainder. In fact, the difference between the sprayed and unsprayed portions was 
so marked that it seems unsafe to ascribe it wholly to the fungicide, it being 
better to content one’s self with the strong indication that the sulphide is likely to 
prove a serviceable preventive of this disease, and to leave the question of its full 
efficiency to be determined by future trials. 
As the value of whatever remedy may be employed, depends en- 
tirely upon its power to prevent the germination of the conidia of 
the fungus, the necessity of making the applications early is obvious.
