Cause not known 
Like peach-yellows this disease is confined to the northeastern 
United States. It has been known for but a few years in this 
country. The origin of little-peach is unknown, but the sug- 
gestion has been made that it came from abroad with Japanese 
plums. The first appearance of the disease in America was 
once believed to have been in Michigan prior to 1893, but there 
are some indications now that it appeared in New York State 
at an earlier date. More recently important notices of little- 
peach have come from New Jersey and from Ontario, Canada. 
This disease is not confined to trees of any particular age, 
although a larger number of the cases are found on trees over 
five years of age. In New York State the Smock and Salway 
varieties remained apparently resistant for several years, but 
finally these have become affected. In some localities of the 
states of New Jersey and Michigan little-peach is a more 
destructive disease than peach-yellows. 
Symptoms. 
Little-peach may or may not appear on a tree at the same 
time as yellows. In the former case the two diseases are often 
considered together. Little-peach is more difficult to detect 
than yellows. In the case of yellows the premature ripening 
of the fruit, the internal red splashes, and the slender shoots 
with narrow leaves are easy marks of distinction. But in little- 
peach, foliage characters are the most prominent earmarks 
of the disease, hence a knowledge of varietal characteristics of 
the foliage is necessary in detecting the presence of this trouble. 
For example, the Elberta has a long, wide, straight leaf with a
