INSECTS INJURIOUS TO CORN 185 



The early planting of field-corn prevents the. moths from lay- 

 ing their eggs upon it, as it will have passed the silking stage and 

 other fields which are in silk will be preferred; it being possible 

 to thus reduce the injury by at least a third by early planting. 



Where the caterpillars of the first generation are working in 

 the unfolding leaves, they are sometimes poisoned with Paris 

 green, mixed with flour or corn meal as used for this pest on 

 tobacco, but as Paris green often burns the foliage powdered 

 arsenate of lead will doubtless be found equally effective with- 

 out burning.
