Control. No canes should be used 

 for planting which give evidence of the 

 presence of moth borer ; all so employed 

 should be treated with Bordeaux mix-

 removal to be effective, it must be done 

 before the base of the shoot has begun 

 to decay, since the caterpillar leaves the 

 decaying shoot and attacks another. 

 Also, it is necessary in cutting out dead 

 shoots to make the cut below the borer, 

 so that it will not be left behind. Dead 

 shoots should be collected and fed to 

 stock as soon as possible after cutting.
