THE BLACKHEAD FIREWORM OF CRANBERRY. 41 



Heavily infested vines should have all of these three applications 

 at the times mentioned and an additional fourth application during 

 the first two weeks of July. In the application of this last spray an 

 effort should be made to hit as many moths as possible with the spray 

 solution. 



A 50-gallon barrel outfit on wheels, with a strong pump, will be 

 found desirable for small bogs. For bogs larger than several acres in 

 area, power outfits should be used. 



In making the applications great care should always be exercised 

 to prevent injury to the vines.
