3d. Plowing. Where bugs are found in considerable num- 

 bers at the edges of spots which they have eaten over, they may 

 be destroyed by plowing under the strip in which they are hiding. 

 Deep plowing, however, is necessary, followed by dragging and 

 rolling in order to completely cover under all vegetation and close 

 up all holes or passages through which the bugs might make 

 their way to the surface. 



If used promptly and thoroughly, these methods are also 

 applicable when the bugs are found to be working during early 

 summer and are all the more effective because the bugs do not 

 scatter over the whole field but stay together in comparatively 

 small areas or strips, and if they are promptly killed over such 

 patches further injury for the season will be very much lessened.
