Related Diseases. 

 Two other diseases should be mentioned in this connec- 

 tion as belonging to the same general group as the yellows. 

 They are the Little Peach of the Northern States and the 

 Peach Rosette of the South. 



Little Peach. The "little peach" resembles yellows in 

 many respects, particularly in its foliage symptoms and yet 

 certain of its symptoms are exactly the opposite, namely, those 

 of the fruit. Fruit on trees affected by "little peach" is un- 

 der-sized and belated in ripening. It is often a week or two 

 weeks or more belated. Its size may be only slightly reduced 

 in mild cases down to little tiny peaches less than three- 

 fourths of an inch in diameter. "Little peach" trees rarely 

 throw the wiry growth. I have only seen it produced where 

 they were cut back, or on very vigorous young trees. It is 

 rarely bushy and prominent, as in the case of the yellows. The 

 foliage characters of "little peach" are so nearly like peach 

 yellows that when the fruit is absent and no wiry growth 

 occurs, as is frequently the case on yellow trees, it is impos- 

 sible to distinguish the two diseases. In practical eradication 

 work there need be no occasion for distinguishing these doubt- 

 ful cases, inasmuch as the treatment is the same. "Little 

 peach" occurs abundantly in Michigan, in some parts of New 

 York State, and was found last summer in New Jersey, one 

 orchard there having been completely wrecked by its attacks. 

 It is usually quicker than yellows in killing the tree, doing 

 this in three years, while the yellows takes five years. It also 

 apparently spreads more rapidly in the orchards and is further- 

 more more difficult to detect in its incipient stages. This 

 makes it harder to handle. 



PeacJi Rosette. The rosette, which occurs in Georgia 

 and the adjacent state of South Carolina, and also to some 

 extent in Missouri and Arkansas, is a still different disease of 

 this same type. The affected trees produce small, very short 

 bushy growth something like the yellows in principle, but so 

 dense as to form rosettes or bunches of leaves on the trees. 

 Affected trees throw their fruit; produce small, green, shriv-
