COLORING OF SEEDS NOT REQUIRED FOR COMMERCIAL SAMPLES

(See pp. 7 and 8 of B. E. P. Q. 368.) The same exemption is extended to

FEDERAL DOMESTIC PLANT QUARANTINES 
July 29, 1936. 
The cooperation of the public is requested in assisting the United States 
Department of Agriculture in its efforts to prevent the spread of certain 
especially injurious insect pests and plant diseases which have been made the 
subject of Federal domestic plant quarantines. These quarantines are promul- 
gated to prevent dissemination within the United States of dangerous plant 
pests new to or not widely distributed within this country. To accomplish 
these purposes it is necessary to regulate the movement of plants and certain 
other articles likely to carry the pests. 
Many persons unaware of quarantine regulations unwittingly offer oppor- 
tunity for establishing new centers of infestation by shipping prohibited or 
uninspected materials. Shippers unfamiliar with Federal quarantines should 
write for information to the Bureau of Entomology and Plant Quarantine, 
United States Department of Agriculture, Washington, D. C, stating the 
kinds of plants and associated articles to be transported, and the points of 
origin and destination. 
QUARANTINES AGAINST DOMESTIC PESTS 
There are now in force 10 domestic quarantines controlling the interstate 
movement within the continental United States of plants and plant products, 
and of certain other materials likely to carry insects or plant diseases. 
These quarantines are intended to protect our agricultural crops and forests 
from pests of major importance. Some of them aid in the effort to eradicate 
the insects and plant diseases, while others are designed to prevent the artifi- 
cial spread of pests which now occur only in limited areas. 
In order to minimize interference with normal commerce, however, the regu- 
lations of most of the quarantines provide that in lieu of complete prohibition 
of the restricted articles, movement may be permitted under inspection or 
sterilization or such other treatment as may be required to insure freedom 
from infestation. 
Insects and plant diseases which are the subject of existing Federal domestic 
plant quarantines are the black stem rust, the white pine blister rust, the 
woodgate rust, the gypsy moth and brown-tail moth, the satin moth, the Japa- 
nese beetle, the Thurberia weevil, the Mexican fruit fly, the pink bollworm, 
and the Dutch elm disease. 
Eradication or control measures against these pests are undertaken by the 
Federal Government in cooperation with and under the direct authority of the 
States concerned. Such efforts have been successful in the eradication of the 
pink bollworm of cotton in an extensive area involving a number of counties 
in the Trinity Bay region of Texas, in several parishes in southwestern Louisi- 
ana, as well as a number of isolated local outbreaks in other parts of the same 
States, and in a limited area in south central Georgia; in stamping out gypsy 
moth infestations in Cleveland, Ohio, in western New York, and in northern 
New Jersey ; and in the eradication of the Mediterranean fruit fly from Florida ; 
and the date palm scale from Arizona, California, and Texas.
