the earth, and atmosphere is too low for the most successful

"The Yellows in the Peach." By C. H. Peck, New York State
Museum of Natural History. pp. 694-95. Ibid. 1879. His
specimens and field notes were from Mrs. L. A. Millington, of
Michigan, "during past two years." I quote:

"Very warm, dry weather has seemed to favor its rapid deveopment."
p. 695.

Oidium fructigenum was found by him on one peach. Mrs. M.
says it rots the fruit and if this is not removed poisons the
twig that bears it so it dies. p. 695.  Peck says it also occurs
on plums and pears.

His conclusion is "I do not think the disease [yellows]
is produced by any ordinary parasitic fungus."
