ANNUAL KEPOKTS OF DEPARTMENT OF AGRICULTURE, 1934 
An effort is made to inspect, in the field, plants imported under regulation 14 
of Quarantine No. 37 during at least two growing seasons to determine their freedom 
from plant pests, particularly plant diseases, which may have escaped detection 
or which were in such an early stage of development as to make detection impos- 
sible at the initial inspection at the time of entry, prior to shipment to the field. 
Only the more recent of the importations show T n in table 22 are still under the 
observation of the Department. Owing to a reduction in funds available for the 
purpose only a small number of importations, as compared with former years, 
were given the field inspection. On the basis of these inspections and of such 
information as was available from inspections of previous years a total of 
12,612,146 plants, bulbs, etc., were released from further observation. This 
represents imported plant material and its increase produced during the two or 
more growing seasons it was under observation, which was found to be appar- 
ently free of important plant pests likely to become established in this country. 
During the fiscal year 118 collections of plant pests, 66 of which were diseases 
and 52 insects, were sent in for verification and determination. Among the more 
interesting pests found were the following: Diseases — Cryptosporium minimum 
(second report for the United States) on Rosa sp., mosaic on Colchicum sp. and 
on Cymbidium sp., all in Pennsylvania, Phomopsis rudis on Colutea kesselringi 
and Laburnum watereri, Rhabdospora rudis on Laburnum alpinum, and Urocystis 
colchici on Colchicum autumnale, all in Ohio, and Uredo nigropunctata on Stan- 
hopea sp. in Maryland; insects — Bregmatothrips iridis (thrips) on iris, Dialeurodes 
chittendeni (whitefly) on rhododendron, Eumerus sp. (Syrphidae) in narcissus, 
Furcaspis biformis (Coccidae) on Cattleya schroederiana, Lepidosaphes tuberculata 
(Coccidae) on Cymbidium sp., and Taeniothrips gladioli (thrips) on gladiolus. 
INSPECTION OF PLANT-INTRODUCTION AND PROPAGATING GARDENS 
As heretofore, plants grown and distributed by the Bureau of Plant Industry 
from its plant-introduction and propagating gardens were inspected and certified 
prior to shipment. Plants shipped from Mandan, N. Dak., Coconut Grove, Fla., 
and Chico, Calif., were inspected by officials of the States concerned cooperating 
with this Bureau. Those distributed from Savannah, Ga., were examined by 
an inspector of this Bureau. Table 37 indicates the number of plants inspected 
and certified for distribution.

INTERCEPTIONS OF PROHIBITED PLANTS AND PLANT PRODUCTS 
A record of the number of interceptions of prohibited plants and plant products 
made by inspectors and collaborators of the Bureau appears in table 38. Many 
of these interceptions were found to harbor insect pests and plant diseases, and 
many others, while showing no infestation or infection, must be considered poten- 
tially dangerous since they came from countries where pests not present in this 
country are known to occur. For example, 1,706 interceptions, representing 
27,420 individual units, pounds, and containers of known hosts of the Mediter- 
ranean fruit fly from countries where that insect is reported to occur, were made. 
Interceptions made at footbridges, ferries, and crossings at the Mexican and 
Canadian border ports have all been considered as having been taken from 
baggage.
