Recent Studies on Peach Yellows and Little Peach 



the northern corner of South Carolina. An isolated area in southern 

 Nevada has been reported. Yellows has never appeared in Cali- 

 fornia and the state has a quarantine against the introduction of 

 trees, pits, or fruit from sections where the disease prevails. 



Little peach is apparently not quite as widely distributed as yellows 

 at present, but occurs from New England as far south as Virginia 

 and west to Michigan, and in some of the other western states in 

 which yellows prevails. 



Peach rosette is confined to certain southern peach regions. It 

 was first reported from Georgia in 1879. Since that time it has been 

 found as far west as Kansas and as far north as South Carolina.

Many estimates of the losses due to peach yellows have been made, 

 but some of the figures are likely to be unreliable. There is no doubt 

 that in many supposed cases of yellows, the symptoms were due to 

 other causes and the losses were overestimated ; but after making due 

 allowance for over estimates we must recognize that the losses have 

 been very large. 



One of the earliest and apparently authentic estimates covers four 

 years of inspection of orchards from about 1879-82 at South Haven, 

 Mich., by Williams, and reported by Smith, 1 as shown in table 1. 



Yellows is supposed to have appeared in Michigan about 1866 or 

 1867, but did not become prevalent enough to attract much notice 

 until about 1870. The period covered by the figures is evidently 

 what might be called a quiescent one, for a few years later Smith 

 writes, "The peach industry was literally swept out of Berrien County 

 by yellows within one decade."
