BUREAU OF PLANT QUARANTINE 31 
Infestations with eelworms (Tylenchus dipsaci) were reported in 1932 in one 
or more plantings in California, Florida, Georgia, Maryland, Michigan, Missouri, 
New Jersey, New York, North Carolina, Ohio, Oregon, Tennessee, Virginia, and 
Washington. In addition to the records for 1932, this species had previously 
been reported in narcissus plantings in Alabama, Illinois, Indiana, Kansas, Ken- 
tucky, Mississippi, Rhode Island, Utah, and Wisconsin. Some of these plant- 
ings have not since been reported as inspected, and infestation may possibly be 
persisting in them. 
Greater bulb flies (Merodon equestris) were reported in California, Michigan, 
New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Virginia, and 
Washington. They have also been reported in previous years in narcissus 
plantings in Illinois, Ohio, and Utah. 
The lesser bulb flies (Eumerus spp.) were removed from consideration under 
the Federal narcissus-bulb quarantine in an amendment which became effective 
on June 20, 1932. Accordingly, most of the State inspectors did not report the 
presence or absence of the lesser flies in 1932. 
Detailed information on the numbers of plantings and bulbs and the extent of 
treatment in the individual States and the District of Columbia is given in Cir- 
cular B.P.Q.— 349, issued on February 17, 1933. 
BLACK-STEM RUST QUARANTINE 
The quarantine on account of black-stem rust (Puccinia graminis), under 
which Federal permits are required for all shipments of barberry and mahonia 
plants (except Berberis thunbergii and its rust-immune varieties) 'consigned into 
or between 13 of the North Central States, is designed to assist those States in 
protecting grain from black-stem rust infection. 
In cooperation with the Bureau of Plant Industry, the premises of some 30 
applicants for permits were inspected, and permits were issued to 25 firms, an 
increase of 5 over the previous year. Sixteen violations of this quarantine were 
intercepted at transit-inspection points during the year. 
According to the Bureau of Plant Industry, the protected States, which have 
been engaged for a number of years in a barberry-eradication campaign, destroyed 
in cooperation with that Bureau 175,951 barberry bushes, seedlings, and sprouts 
during the calendar year 1932, making a total of 18,065,403 since the campaign 
was started in the spring of 1918. The States in which this work is being carried 
on are Colorado, Illinois, Indiana, Iowa, Michigan, Minnesota, Montana, Ne- 
braska, North Dakota, Ohio, South Dakota, Wisconsin, and Wyoming. 
PHONY-PEACH DISEASE QUARANTINE REVOKED 
The phony-peach disease quarantine was revoked, effective March 1, 1933. 
When the quarantine was placed by the Department, effective June 1, 1929, 
it was believed as a result of surveys in 1926, 1927, and 1928, that the disease 
was confined to the States of Georgia and Alabama, although it was known to 
have been present in Georgia for some 50 years. Surveys during the next 2 
years disclosed infections in Mississippi, Texas, Arkansas, Louisiana, Tennessee, 
North Carolina, and South Carolina. Surveys in 1931 showed further infections 
in Florida and Illinois. During 1932, infected trees were found in southern 
Oklahoma and in southeast Missouri. Scattered infections were also found 
during the year in new localities in Arkansas, Illinois, and Texas. 
The widely separated infections in some of the States concerned have made 
the enforcement of intrastate quarantine regulations by these stales imprac- 
ticable, thereby complicating the problem of maintaining Federal control of 
interstate shipments, and this condition indicated that further control of spread 
could be handled more sal isfactorily by improved and modified nurserj -inspectioo 
methods in the various Stales than by enforcement of the type of Federal quar- 
antine regulations previously in efl 
The investigations of the* Bureau of Plant Industry point BO strongly io the 
peach borer as the carrier of the disease, that the future acti\ ities of this Bureau 
with respect .to phony-pcach-discase control will be confined Largely, insofar as 
funds and facilities permit, to assisting the States in the development and adop- 
tion of improved culling practices to eliminate all peach-borer infested or injured 
stock, and increasing the efficiency of inspection in peach-growing nurseries and 
the environs by directly aiding in such sur\ 
The States of Arkansas, Delaware, Georgia, Mississippi, and Oklahoma pro- 
mulgated Slate regulations directed againsl this disease after the Federal quaran- 
tine was taken off. Other Interested States are handling the problem of prevent-
