Peach Yellows. The first symptoms in a young tree, previous to 

 bearing, are indicated by the leaves of one or two limbs turning from 

 a rich dark green to a "yellowish green or reddish rusty green'' color;

 leaves ripen and fall earlier than normal leaves. The fruit buds are 

 larger and more mature in appearance and in the spring will invariably 

 bloom earlier than healthy buds. In some instances, the symptoms are

 in cases of "Little Peach." 



Upon bearing trees, there may be any one or all of the following 

 symptoms: the fruit may ripen prematurely — one to three weeks — upon 

 one or two branches or over the entire tree. The fruit may have numerous 

 red spots on the surface, the spots sometimes extending in red streaks 

 partially or wholly through the flesh to the pit. Often the flesh, about 

 the pit, is full of radiating streaks of red. The surface of the fruit may 

 be smooth or considerably roughened and the flesh more or less stringy 

 and very insipid. The leaves may be yellowish pale or reddish rusty 

 green in color, usually rolling and drooping, In advanced stages,
