REPORT OF THE FEDERAL HORTICULTURAL BOARD. 



United States Department of Agricultuhe, 



Federal Horticultural Board, 



Washington, D. C, October S, 1920. 

 Sir: I submit herewith an executive report covering the adminis- 

 tration of the plant quarantine act for the fiscal year ended June 30, 

 1920. The activities of the Federal Horticultural Board are indi- 

 cated in the list of current quarantine and other restrictive orders 

 appended to this report. These activities have been rather fully- 

 recorded in the Service and Regulatory Announcements of the 

 board issued during the year, and these announcements, therefore, 

 constitute an available record in some detail of the work of the 

 board. This annual report is limited to a general discussion of the 

 more important only of these activities. 

 Respectfully, 



C. L. Marlatt, 



Chairman oj Board. 

 Hon. E. T. Meredith, 



Secretary of Agriculture. 



LINES OF WORK. 



The work of the board may be classified as follows : 



1. The administration of special appropriations by Congress for the 

 control or extermination of newly established plant enemies, such as 

 the appropriations on account of the pink boUworm of cotton and the 

 potato wart disease and cooperative work in relation to appropria- 

 tions assigned to the Bureaus of Entomology and Plant Ind\istry for 

 the control of other new plant pests, the quarantine provisions in 

 relation to which are enforced in cooperation with this board under 

 the plant quarantine act. 



2. The port inspection service maintained by the board as an essen- 

 tial part of the enforcement of the several foreign quarantines and 

 restrictive orders. 



3. The general administration and enforcement of the miscella- 

 neous foreign and domestic quarantine and other restrictive orders 

 listed at the end of this report. 



In the discussion of these more important activities, unless other- 

 wise indicated, the record is carried to the date of publication and, 

 therefore, covers substantially the crop season of 1920.
