MISCELLANEOUS WORK IN NEW YORK STATE. 
By D. G. FAIRCHILD. 
TREATMENT OF APPLE SCAB AT BROCKPORT. 
Forty trees, the property of Mr. Udell, were chosen for this experi- 
ment. Twenty of the trees were of the Twenty-Ounce variety, and 
in bearing at the time of treatment, while the others (Baldwins) were 
not bearing. The following fungicides were employed to ascertain 
their relative effectiveness: 
(a) Ammoniacal solution of copper carbonate (5 ounces copper carbonate dissolved 
in 8 pints of ammonia (26°), and diluted with 45 gallons of water). 
(b) Modified eau celeste (14 pounds copper sulphate, 14 pounds sodium carbonate, 1 
pint ammonia (26°), 52 gallons of water). 
(c) Bordeaux mixture (14 pounds copper sulphate, 14 pounds fresh lime, 45 gallons 
of water). 
(d) Potassium sulphide (5 ounces potassium sulphide in 48 gallons of water). 
Three treatments were made by Mr. Udell. On May 4,* ten days be- 
fore blooming, May 19, while in full bloom, and on June 8. An ex- 
amination made July 11 showed an entire absence of Fusicladiwm from 
both treated and untreated trees. Thus the experiment, owing to the 
absence of the disease, was entirely negative. 
TREATMENT OF PLUM LEAF-BLIGHTt IN THE ORCHARD. 
Two experiments in quite widely separated orchards at Geneva, N. Y., 
were made in the treatment of leaf-blight. The trees were kindly put 
at the disposal of the Department by their owners, Mr. T. C. Maxwell 
and Mr. A. Hammond, who aided the experiment in every possible 
way. According to the statement of the owners, the leaf-blight had 
often defoliated the trees in July and August, and the experiments were 
planned with the view of preventing this destructive early fall of the 
leaves. It was also desired to test in a comparative way the effects of 
a few fungicides, either not heretofore employed or not employed in so 
dilute a form. Unfortunately for the experiment, leaf-blight appeared 
in the orchards unusually late, not causing serious leaf fall until the 
latter part of September. Thus this experiment was also negative, for 
the fungicides applied in May and June failed to prevent the appear- 
ance of the disease in September. It seems best, however, to place 
upon record the results obtained, and to also make a note as to the 
effects of the fungicides upon the foliage. The following fungicides 
were employed: 
(a) Ammoniacal solution (0.1 ounce of copper carbonate dissolved in 0.1 ounce 
ammonia per gallon of water). 
(b) Potassium sulphide (0.1 ounce per gallon of water). 
*With the exception of potassium sulphide, which was not applied until the 12th. 
t Disease caused by Cylindrosporium padi Karsten.
