have been successful up to the present time just in proportion 

 to the care used in eradication. 



In New York State a good many of the better class of 

 growers have been persistently eradicating this disease for 

 twenty years or more. These carefully worked orchards are 

 often situated in neighborhoods where orchards have been 

 seriously affected or totally destroyed by yellows and little 

 peach. I can cite the cases of Mr. Jesse Lockwood and Dr„ 

 C. A. Ring of Olcott, New York. Also the orchard of Mr. 

 Willard Hopkins at Youngstown, New York. 



Eradication Tests. About five years ago, when the 

 writer's investigations led him to the conclusion that little 

 peach belonged to the yellows group, an eradication test was 

 started in a definite area in Saugatuck Township, Michigan. 

 This area contained about seven square miles, was thickly 

 planted to peach orchards and had about one hundred and 

 forty thousand peach trees. There were some 4,000 or 5,000 

 trees diseased' that were found the first season. Only a small 

 proportion of these, however, were affected with yellows. 

 Three inspections were made and the diseased trees were 

 removed with a fair degree of promptness after each inspec- 

 tion. The next year only between four and five hundred dis- 

 eased trees were found, being onl)- a small fraction of one 

 per cent. A slight increase of somewhat over a thousand trees 

 was found the third season, but the total number of diseased 

 trees in this area was less than one per cent. Only about 

 one-fifth of these were affected with yellows, the remaining 

 four-fifths being little peach. Similar results were obtained 

 by the local yellows commissioners in the fourth season, which 

 was 1906, and the orchards in this area are still standing in 

 good condition, as far as the yellows and little peach are con- 

 cerned. 



A similar eradication test was started in 1906 in an area of 

 some six or seven square miles around Youngstown, New 

 York, in co-operation with the Cornell State Experiment Sta- 

 tion, through arrangements with Professors Bailey and Craig. 

 The figures for the past season, which was the second in this 

 district, showed the number of trees marked and condemned
