7() ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1953 
a survey for triquetra and Oncometopia wndato made in Florida, 
South Carolina, North Carolina, Virginia, Maryland. Pennsylvania, 
West Virginia, Tennessee, Kentucky, Indiana. Illinois, and Arkansas. 
0, wxdata was found to occur throughout and even beyond the area 
where phony peach disease has ever been reported. On the other hand, 
triqui 'f/ was not found north of the 35th parallel, reaching that lati- 
tude only in the coastal plain of North Carolina. 
GOLDEN NEMATODE CONTROL 
Surveys 
Surveys on Long J -land during 1952 revealed an additional 1,050 
acres infested with the golden nematode, bringing the total acreage 
infested to L0,941. More than -1.000 of these acres haw been removed 
from agriculture by real estate development. Most of the fields con- 
taining these infestations were intermingled with or adjacent to pre- 
viously infested holds in Nassau and Suffolk Counties. Inspections 
of 277 Qurseries and retail plant sale- establishments in Manhattan, 
Nassau, Queens, and western Suffolk Counties resulted in the finding 
of 10 such establishments infested with the golden nematode. This 
increases to 94 the number of infested establishments. 
Surveys in the tomato- and potato-producing areas in nine western 
and in two eastern States other than New York failed to produce 
evidence of outlying infestations. 
A single golden nematode cyst was recovered from a soil sample 
taken in October 1952 from a 7 1 -. acre farm near Matawan. N. J. 
This farm is remote from the tomato- and potato-growing areas of 
New Jersey. Soil samples were collected at this farm when it was 
learned that waste material from a mill at Rahway that processed used 
agricultural burlap of foreign origin had been obtained by the farmer 
and incorporated into bis soil. A sample of waste material collected 
at the mill also contained a golden nematode cyst. The mill was 
operating under an agreement that provided that all waste would be 
burned. Waste material from this mill had been spread on only one 
other farm. This was the State Prison Farm at Rahway. Sampling 
of -oil t here has been with uegal ive results. The State of New Jersey 
immediately established safeguards at the Matawan farm. Heavy 
dosages of a -oil fumiganl were applied in the spring of L953 to the 
land- under suspicion. 
I rolden nematodes were recovered from soil in railway cars hauling 
potatoes from Leon. Trinidad, and Silao in the State of Guanajuato, 
Mexico, in June L953. The iniested soil was intercepted at Monterrey, 
Juarez, and Piedras Negras. This was the firs! indication that this 
injurious potato pesl occurred in Mexico. 
Isolated Infestation al Mount Sinai Treated 
An isolated infestation of the golden nematode in the potato-pro- 
ducing area of Mount Sinai, near l'.ut Jefferson, Suffolk County, 
L<»nL r Island, was treated in the fall of L952 with D-D as a suppres- 
sive measure. It i& anticipated thai this treatment will render non- 
viable from 95 to 99 percent of the cyst population in the infested 
field, thereby reducing further hazard of spread to other part- of this 
important potato producing area.
