As has been pointed out by the late Professor F. M.Webster, the 

 control of forage crop insects must differ fundamentally in method 

 from the control of the insects of the orchard and garden. The 

 gardener and the orchardist are able to give individual attention 

 to their plants or trees, while the grower of forage crops must have 

 recourse to more wholesale methods of destruction or prevent 

 attack by such adjustments of his farm practices as will least inter- 

 fere with the growing of a regular succession of crops of the 

 desired kind. In practice this end is to be attained by a proper 

 arrangement of the rotation, by shortening the rotation, and in 

 some cases by plowing at the proper time for the destruction of 

 underground insects. 



While the losses to forage crops from insect attack are usually 

 not so apparent as those experienced by the fruit grower, they 

 are none the less real. Much of the loss is caused by insects that 

 work in the soil, where they rarely attract the farmer's attention 

 until after the damage is done. Although we hear comparatively
