BUREAU OF ENTOMOLOGY AND PLANT QUARANTINE 77 
Regulatory Activities 
New York State's golden nematode quarantined area includes the 
potato-growing section of Nassau County and a small segment of 
Suffolk County. The quarantine, cooperatively enforced, prohibits 
movement of seed potatoes from the regulated areas and places restric- 
tions on the movement of culinary potatoes, topsoil, root crops, tomato 
seedlings, vegetable and ornamental plants, as well as used machinery, 
containers, and equipment. The Bureau cooperated in regulating the 
movement of those comodities which included 506,000 bushels of 
potatoes and 900,000 cubic yards of top soil. Nearly 1,500 pieces 
of farm and other machinery used on nematode-infested properties 
were steam-cleaned. In addition, 20,750 burlap bags and other con- 
tainers from such properties were fumigated with methyl bromide. 
Soil fumigation was continued at all infested nurseries. Treating 
was done at 48 nursery establishments in western Long Island. 
Owner-operators assisted by preparing the soil and applying a water 
seal after treatment. 
Owner-operators of 1,124 acres of infested land were compensated 
at the rate of $60 an acre to retire such lands from potato production 
to keep populations at a minimum and thus ease the regulatory prob- 
lem. Costs of this program were shared equally by the State of New 
York and the Federal Government. 
Search for a Dip To Control Golden Nematode Intensified 
A screening program has been inaugurated in an attempt to find a 
chemical dip that will destroy golden nematode cysts attached to im- 
ported nursery plants or bulbs without injuring the living plant 
material. The increasing number of importations found with attached 
golden nematode cysts, because the plants have been grown in soil 
formerly used for potato culture, has created an urgent need for such a 
chemical. The program is cooperative with the Bureau of Plant 
Industry, Soils, and Agricultural Engineering. 
TOBACCO CYST NEMATODE 
A cooperative Federal-State survey for the tobacco cyst nematode, 
previously discovered in Connecticut, was initiated in nine South- 
eastern States in April 1953, and was in progress at the end of the 
fiscal year. Florida, Georgia, Kentucky, North Carolina, South Caro- 
lina, Tennessee, Maryland, Virginia, and Pennsylvania will be in- 
cluded in the survey. None of the soil samples collected during the 
fiscal year showed the presence of this nematode. 
JAPANESE BEETLE INVESTIGATIONS AND REGULATORY 
ACTIVITIES 
Milky Disease of Japanese Beetle Grubs Well Distributed 
To accelerate spread of the milky disease of the Japanese beetle 
grub, 6,555 pounds of milky disease spore dust were prepared by the 
Bureau for the State of Maryland. Inoculated grubs used in the 
preparation were furnished by the State.
