166 STATE POMOLOGICAL SOCIETY. 



Experiments have been made at the New York Experiment Station 

 the past year to combat this disease. A tree badly affected, in 1885, 

 was selected to experiment with, one-half of the tree was spraj^ed 

 with hypo-sulphide of soda ; two weeks later it received another ap- 

 plication ; the result at harvest was that this portion of the tree 

 yielded much better fruit than the other. 



This is a disease which causes an immense loss, rendering the 

 quantity of number two apples unnecessarily large. Mr, Charles S. 

 Pope, the President of the Maine Pomological Society, wrote to the 

 Department a few weeks ago relative to this disease, sa^'ing it had 

 damaged him to the extent of $1,000 the past season ; the Baldwin 

 was especially affected. 



I have noticed apples in our Washington market, particularly £he 

 Bellflower, badly affected with this disease. 



The Secretary, in reply to the Professor's inquiry, would say, 

 That with him the Carolina Red June, Fall Pippin, Red Astrachan, 

 and Early Harvest, were among the varieties most affected, the loss 

 to the first named being fully fift3' per cent 



Wm. R. Ward. The Greenings and Baldwins have been affected 

 this year badly ; had never seen them troubled before. I attribute 

 the early dropping of the apples to this cause. However, this may 

 be due to the very dry season. I think a solution of London pur- 

 ple or Paris green sprayed on the trees would be beneficial. 



Prof. ScRiBNER. The fungus of the apple-scab does not cause 

 the apple to rot. These apples keep as well as others. Under the 

 fungus growth is found a corrugated layer that protects the healthy 

 tissues of the apple from decay. There are other fungi, more con- 

 ducive to rot, that attack the apple ; I have noticed several this 

 season, I have noticed that apples affected with the scab, if kept 

 in a warm place, will commence to rot about this fungus sooner than 

 elsewhere. 



I have noticed, also, that on trees affected with this fusicladium 

 the leaves fall prematurely, and when the apples are attacked when 

 quite young the disease will doubtless hasten maturity and cause the 

 premature falling of the fruit. 



The Secretary had noticed that where the fruit was attacked it 

 stopped the growth and expansion of the fruit at the point of 

 attack. 



Prof. Scribner. This fungus distorts the apple very much ; some- 

 times to the extent to cause the apple to crack.
