late summer plowing. 



The rough-headed corn stalk-beetle enters the pupa stage during 

 the latter part of August and it is in this stage that the beetle is most 

 easil}^ destroyed, the least disturbance being sufficient to kill the 

 pupa?. For this reason, wherever possible sod lands should be plowed 

 the last week in August or the first week in September for Virginia, 

 but earlier than this for more southerly localities. 



SUMMARY OF CONTROL MEASURES. 



1. Eliminate all old pastui-es or waste land, especially low, moist 

 areas, and drain such lands thoroughly. 



2. Pasture hogs in waste or pasture lands that can not be con- 

 veniently drained and cropped. 



3. Plant corn early, say about April 20 for tidewater Virginia, and 

 earlier for more southerly localities. 



4. Give liberal applications of barnyard manure or commercial 

 fertilizers whenever practical. 



5. Employ children or cheap labor to collect and destroy the 

 beetles when a field first shows injury. 



0. Do not allow corn to follow sod if possible to avoid it. ' 

 7. Plow sod land in late summer and early fall in order to destro^^ 

 the pupjB of the rough-headed corn stalk-beetle.
