CONTROL OF PEACH MOSAIC AND PHONY PEACH DISEASES 
Funds for prosecuting the peach mosaic and phony peach control 
projects were derived from regular appropriations, supplemented by 
substantial emergency-relief allotments and contributions from the 
States, the latter of which nearly equaled regular Federal appro- 
priations. 
Almost 1G.000.000 orchard trees on more than 145.000 properties 
were inspected. In excess of 147,000 diseased tre found, more 
than 120,000 of which were destroyed. While comparisons with pre- 
vious years' findings are difficult, there is evidence of substantial reduc- 
tions in incidence of new ease- of these two diseases. 
With labor employed with Emergency Relief Ajdministration funds, 
between 9 and 10 million escaped and abandoned u removed 
to prevent their becoming harboring places for thesi ad to 
eliminate the necessity for subsequent inspections. 
[inspections were conducted in 455 counties in l j 4 Sen ates 
from the Atlantic to the Pacific Four additional counties were found 
infected with mosaic and 7 with phony peach disease I first time. 
During the last quarter of the year inspections were made of nurs- 
eries and budwood sources and their environs. Nearly TOO nurseries 
growing more than 26 million trees were involved. In the States 
infected with phony peach all diseased trees were n 
nursery environs before June 30 3 thereby complying with all require- 
ments for certification under the standard State quarantines. In the 
mosaic area 31 nurseries and 7 dealers' sales yards failed to meet the 
requirements of the quarantines and were barred from shipping nurs- 
ery stock. Most of the latter nurseries were producing stock for home 
use only. Cooperation was continued in assisting Sent-- in the enforce- 
ment of their standard quarantines relative to these diseases. 
In cooperation with the Colorado State Department of A.griculture, 
a series of "oil" variety peach trees were grafted with scions from
