336 ReEPoRT OF THE ACTING POMOLOGIST OF THE 
ANTHRAONOSE (Sphaceloma ampelinum, DeBary). 
This disease, like black rot and downy mildew, attacks all parts aes 
of the vine, leaves, growing shoots and fruits, and seems to ber ‘ 
harder to combat than the above-named diseases. Conflicting 
statements are given as to the effectiveness of the copper com- : 
pounds when used as remedies for this fungus. Inreplytoan 
inquiry received last July, with specimens of the vine showing 
the disease in an advanced stage of development, the following 
line of treatment was outlined: “The season is so far advanced 
and the disease has obtained such headway, as evidenced by the 
samples of vines sent us, that it will be hard work for you to 
check it this season, but we should cut off all the diseased wood 
that can be spared from the vines and burn it, together with 
leaves that have fallen. Then spray the remainder of the vines 
with eau. celeste, made by dissolving one pound of sulphate of 
copper in two gallons of hot water. After it has cooled add one 
and one-half pints of commercial ammonia. When ready for use, 
dilute to twenty-two gallons with water. Next spring prune 
and burn all diseased canes, and spray once with the mixture 
before the buds begin to expand and again as the buds 
are opening. Continue this treatment at intervals of ten 
days or two weeks until you have made four or five appli- 
cations. Also try sulphur and powdered lime, in equal 
parts, applied with a sulphuring bellows on the first appear- 
ance of the disease.” To find if the department at Washington 
could give additional, or a more perfect, treatment for this 
disease the question was submitted, with a copy of the above. 
The following reply was received from Prof. BE. T. Galloway, Chief 
of the Division of Vegetable Pathology :

Dr. Perer Couurer, Director New York Experiment Station, Geneva, N. Y.: 
Dear Sir.— Your favor of August fourth addressed to the Secretary 
and concerning the treatment of anthracnose of the grape has been 
referred to me. I can offer but few suggestions that will aid you, as 
the treatment you have recommended covers fully all we know on the 
subject. The fact is we are yet in the dark as regards an effective 
preventive of this disease. We have experimented with almost every- 
thing, and so far the mixture of sulphur and lime seems to have 
given the best results. In some cases Bordeaux mixture, ammoniacal
