NINTH ANNUAL MEETING. 31 



with the Crown Gall. There has been no remedy found 

 yet for it, and the only thing is to look out for it on nursery 

 stock and discard all stock that shows any signs of it, and 

 also to avoid setting peaches on ground that has had apples 

 or raspberries that have had the Crown Gall. 



The next disease which may be mentioned is the Brown 

 Rot of the fruit, caused by the fungus Monilia fructigena. 

 As a rule, this rot is confined to the fruit, which it destroys 

 with extraordinary rapidity. Occasionally, however, espe- 

 cially if the weather is very damp, warm and close, it will 

 attack the flowers, the twigs and even the leaves, causing 

 them to decay. Even should the trouble be then checked 

 by a return of dry weather, the fungus will remain in the 

 affected parts, ready to induce a fresh outbreak of the dis- 

 ease with the return of damp weather. In like manner, 

 when the fruit has been subject to the rot, the latter 

 remains alive in the mummified fruit, which is usually 

 allowed to remain all winter on the trees, or on the ground 

 where it has fallen, and there a few hours of warm, wet 

 weather in the spring, calls it into activity again ; myriads of 

 spores are produced on the mummified fruit and thence they 

 are borne by the wind in all directions to infect the young 

 growth and finally the fruit also. Spraying, even where 

 it can safel}^ be practiced, is only a partial remedy for this 

 disease, though in the Delaware orchards Bordeaux Mix- 

 ture has shown beneficial results and without injury to the 

 foliage. Here in Connecticut, however, in season of 1898 

 peach foliage in Mr. J. H. Hale's orchard was very seri- 

 ously injured by the use of a well-made Bordeaux Mixture 

 of moderate strength. 



[ Mr. Hale here remarked that the results were so 

 serious in his orchard that the Department of Agriculture 

 at Washington sent on an expert in spraying, and a test 

 was made with Bordeaux of various strengths, var3dng 

 from one to six pounds of copper sulphate to fifty gallons 

 of water, some with equal amounts of lime and others 

 with an excess of lime, but in every instance the trees 

 were badly defoliated, convincing him that it was not safe 

 to use Bordeaux Mixture of any strength upon peach 

 foliage here in Connecticut.]
