36 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1934 
trees and other trees budded on peach roots which were intended for movement 
during the season of 1933-34. The environs of 96 nurseries were found to be 
apparently free from infection for a radius of 1 mile. The disease was found within 
that distance' of one or more plantings of the other 43 nurseries inspected. In 
Arkansas, Florida, Missouri, and North Carolina, the work was carried out 
entirely by the State nursery-inspection organizations, and in the absence of a 
detailed report from the State inspectors, the work in these States is not included 
in the table. In addition to the figures shown, the Illinois inspectors covered the 
environs of 2 nurseries without finding phony peach disease within the area; 
and those of Georgia covered the environs of 5 nurseries, and in each case found 
the phony peach disease within the area.

1 Peach stock in the exposed nurseries was later called free from borer-injured trees under State and 
Federal supervision except that in Alabama the work was practically all done by State inspectors and in 
Mississippi much of the exposed stock happened to be unsalable for other reasons. 
2 No information was received as to the amount of stock in 2 nurseries in Georgia, 3 in Illinois, 2 in Okla- 
homa, 1 in Tennessee, and 2 in Texas. None of these except the 2 in Georgia, had been exposed to infection. 
During the digging and shipping season, the Bureau received requests from the 
States of Alabama, Georgia, Tennessee, and Texas for assistance in improving 
the efficiency of culling susceptible nursery stock. In this work the State and 
Federal inspectors endeavor to find the most positive and definite ways of de- 
termining borer infestation and injury. In addition to the peach trees so culled, 
small quantities of flowering peach and of plum and apricot trees budded on peach 
roots were also examined. The fruiting-type peach trees included stock of the 
four principal nursery classifications, namely, June buds, dormant buds, year-old 
June buds, and carried-over dormant buds. The term "June buds" refers to 
seedling trees that are budded in June so that the resulting nursery stock is 
ready for sale the same fall or the following spring, and the term "dormant buds" 
refers to nursery stock that is not budded until the late summer and fall so that 
the trees are not ready for sale until the following year. The other two groups 
include trees which are 1 or more years older than the June buds or dormant 
buds. 
Of special interest in this connection is the fact that peach-borer-infested and 
borer-injured trees were found in each of the four classifications as well as in the 
plum, apricot, and flowering peach trees budded on peach roots. It had not 
previously been certain that trees as small as June buds were attacked under 
field conditions in commercial nurseries. June-bud stock is exposed to infesta- 
tion during only one season, and throughout a large part of the peach borer 
egg-laying period the small trees have very little top growth. Either the trees 
are so small that they are not attractive to the borer moths when the eggs are 
laid or possibly the absence of shade results in an unusually high mortality of the 
eggs and young borers through drying. In those cases where detailed notes were 
taken, the average number of June buds infested or injured amounted to 1.9
