Copper carbonate 1 0z., ammonia to dissolve it, 5 gals. water. 
Copper carbonate 3.2 oz., sodium carbonate 1.6 oz., ammonia 
to dissolve them, 5 gals. water. 
For the remainder of the season these rows were all sprayed 
with potassium sulphide 1 oz. to 2 gals. water, six applications 
being given. 
SUMMER TREATMENT. 
This part of the work was divided into three series as was the 
work at Trumansburg. In Series I the work was begun very 
early, April 18; in Series IL medium early, April 28; and in 
Series III late, May 9. Later applications were made May 23, 
June 5 and 15. 
The various solutions used were: 
Pottassium sulphide, 1 oz. to 2 gals. water. 
*Soda-Bordeaux,— *soda (lye) 1 pound. 
Copper sulphate 3 pounds. 
lime 5 oz. 
Water 30 gals. 
“Copper carbonate 1 pound, sodium carbonate (sal soda) 4 
pound, enough strong ammonia to dissolve the copper tarbonate, 
50 gals. water. 
Ammoniacal solution of copper carbonate,— copper carbonate 
5 oz., ammonia 3 pints, water 50 gals. 
Each of these solutions was applied to a separate row in Series

The season was not favorable for the growth of mildew, a small — 
amount appearing on the fruit, but none on the new growth. A 
very little of the disease was noticed June 15. The bushes made

4 This remedy was recommended by Mr. David Allerton and Mr. J. A. Hep- 
worth, of Marlboro, N. Y., who have used it successfully against mildew on 
American varieties, principally Houghton. There seems to be no reason from 
a chemical standpoint why sodium carbonate should be used.
