 heap sight of dishonor." 



There are of course other considerations in the control of the Hessian fly such 

 as the proper preparation of seed bed and use of fertilizers which enable plants 

 to withstand injury, but it is not my intention here to go into details as I wish 

 only to call your attention to the general subject of our problems. All of the 

 methods of preventing or overcoming Hessian fly injury are what we might term 

 good agricultural practices. Plowing under wheat stubble, except where it bears 

 a good stand of clover, is good practice according to the agronomist, sowing after 

 the fly-free date is, generally speaking, the best date to sow wheat regardless of 

 insects, and the preparation of the seed bed and use of fertilizers are good agronomic 

 practices pure and simple. Progress has been made with so-called fly resistant 

 wheats and one or more of the wheats which are showing promising resistant 

 qualities likewise rank above the average in yields.

The past season we have experienced the most general and serious outbreak 

 of grasshoppers for many years. Two years ago the grasshoppers were noticeably 

 abundant in a few localities and in general the areas of grasshopper abundance 

 were somewhat enlarged last year, while the past season they have appeared quite 

 general and destructive in states where they have heretofore been of but comjiara- 

 tively little importance. There is every reason to believe that they will continue 

 to be abundant next year, although probably not as severe as the past season. 



As would be expected, the grasshoppers originated in fields such as timothy, 

 blue grass and clover. The casual observer first noticed injury to clover towards 

 cutting time wlien he found the plants completely defoliated, nothing remaining 

 but the bare stalks and heads. The hoppers then left the clover for new fields, 

 attacking such crops as were handy, as corn, soy beans, and navy beans-: and not 

 infrequently young orchards were defoliated. Thus at New Concord. Ohio, we
