We also respectfully recommend to the Dominion of Canada Department of Agri- 

 culture, the continuance of the present policy in regard to quarantine measures as a 

 means of control. 



We would recommend very careful scouting of areas adjacent to the western infes- 

 ted districts bordering on Lake Erie (both in the United States and Canada) in order 

 to speedily determine th,e extent of the infestation, since this would assist in formulat- 

 ing quarantine restrictions and aid in determining the policy in relation to control 

 measures. 



It is suggested that scouting work in territory adjacent to the infested areas in New 

 England and New York be continued to such an extent as to determine quarantine 

 lines. 



State and Provincial Policies. The closest possible cooperation in both 

 quarantine and control work with federal authorities is urged. 



State and Provincial quarantines should coincide with federal regulations. 



The authorities in infested States and Provinces are urged to make financial pro- 

 vision for cooperative work since this may mean maximum participation on the part 

 of the Federal Governments. 



The attention of the State and Provincial officials is called to the desirability of 

 utilizing the extension service and all publicity agencies in developing a proper attitude 

 toward control of this pest and the importance of keeping the infestation in sparsely 

 infested areas down to a practical minimum, particularly in strategic localities. 



Investigations. It is understood that the U. S. Bureau of Entomology is now 

 compiling a record of the history of this insect in European countries and it is hereby 

 urged that this work be speedily completed and made available to American entomol- 

 ogists. 



The recent great extension of the Corn Borer infestation and the need of the devel- 

 opment of control measures in the immediate future leads us to urge the great practi- 

 cal importance of a close study of this insect, by North America entomologists, in 

 various European countries in order that information thus obtained may be made 

 available to the entomologists of America and by them applied to the solution of the 

 numerous problems in relation to the control of this pest. 



Inasmuch as all control work must of necessity be based upon exact knowledge of an 

 insect, it is our opinion that facilities for investigational work and the introduction 

 of parasites might be somewhat expanded. 



The conference has noted with pleasure the close cooperation in both control and 

 investigational work between the United States and Canadian officials. 



Methods Found of Value in Control Work. Cut corn close to the ground and 

 as early as practicable. 



Ensile entire crop whenever possible and this should include all waste from canning 

 factories. 



Shred or cut cornstalks before feeding, since this kills many borers and promotes 

 consumption of the fodder. 



Uneaten cornstalks, including corn stover in field, lot or barn, or parts of stalks, 

 should be completely plowed under or burned by May 15. Such material should not 

 be used for bedding or thrown into the manure. 



Fall plowing, especially early fall plowing, thoroughly done, kills many borers. 



Heavy rolling prior to plowing is suggested. 



Burn weeds and grass in or near infested corn.
