FIELD COVERED. 



The Federal plant quarantine act has for its object the prevention 

 of entry into the United States of new and important insects or 

 plant diseases injurious to agriculture, horticulture, and forestry, 

 and the prevention of spread in the United States of any such pests 

 which may have gained more or less limited foothold. In connection 

 with the latter, the board is charged, either directly or in cooperation 

 with the bureaus concerned, with the control and, if practicable, the 

 eradication of such pests. To give such protection now involves the 

 administration and enforcement of some 22 foreign and 15 domestic 

 quarantines. 



A brief record of the more important of the activities of the board 

 is given in this report, including statistics of the importation of such 

 controlled products as cotton, potatoes, fruits, nursery stock, etc. 

 The detailed record of the work of the board, in relation to its various 

 quarantine and other special subjects, is given permanent record in 

 the Service and Kcgulatorv Announcements publisluMl from time to 

 time during the year. 



CONTROL OF IMPORTANT NEW PLANT PESTS. 



The Department of Agriculture is now attempting to prevent the 

 spread and in some instances to eradicate a number of important 

 introduced pesjfs which still have a rather limited foolliokl. These 

 include, among insect pests, the pink boll worm of cotton, the 

 European corn borer, the gipsy and orown-tail moths, the Japanese 

 beetle, and a number of minor enemies. Among plant diseases, 

 similar control is being attempted in the case of the- potato wart, 

 white-pine blister rust, citrus canker, and certain diseases of small 

 grains. The progress made in this work Avill be briefly summarized
