Genera] Decline in Peach Mosaic Infection 
A survey during 1951 in the peach mosaic infected States of Arkan- 
sas, ( lalifornia, ( Jolorado, < Oklahoma, Texas, and CFtah resulted in the 
finding of 5,219 peach mosaic t rees among the 3,300,000 t rees inspected, 
or a disease incidence of 0.16 percent. This continued the general 
animal decline in mosaic from the peak year of L935, when an inci- 
dence of L16 percent was observed. Erath and Fannin Counties, 
Tex., have been found Free of the disease for three successive years and 
were released from State quarantine regulations in L951. 
Wore Grower Participation in Phony Peach Control 
Nearly 6 million peach tree- were inspected for phony peach ii 
tion in the States oi Alabama, Arkansas, Georgia, Florida, Louisiana, 
ssippi, Missouri, North Carolina, South Carolina, T< 
I 3. This virus disease is the most serious the \ each in 
the Southeastern States. The inspections were made or prop- 
erties in 1 I s counties. This resulted in the finding of 1 hony 
trees on 963 properties, or a disease incidence of 2 percent. A survey 
was also made in Virginia but no disease was found there. 
In the heavily infected phony areas of Alabama and <"« 
growers participated to a greater degree than in past years by fur- 
nishing labor to delimb phony trees, t«> remove stumps of diseased 
. and i" destroy wild plums growing near orchards, 
incidence in this area showed an increase in 1951 over the preceding 
_\ ea i . 
All nurseries in the phonj peach infected area nuali ied t r certi 
fication of the host stock on their premises. Kih\ four nurseries and 
dealers in the peach mosaic infected areas of Arizona and New Mex- 
ontaining 7. v "" trees, were found ineligible for certification. 
M. than 1.7 million trees in 264 nurseries were determined as eli-
