FIRE BLIGHT. 



This is the most destructive disease of the pear; it also 

 attacks the apple and other related trees. Extreme care and 

 thoroughness are necessary in dealing with this disease. Fire 

 blight can be controlled only by cutting out all diseased tissue 

 as soon as detected and burning it. Special attention should 

 be given to the prevention of the formation of any "hold- 

 over" cankers. If such are formed they must be removed 

 before the trees blossom the following spring. Examine not 

 only branches but trunk, and even roots. Sterilize tools and 

 wounds made in cutting and the disease frequently with Solu- 

 tion of corrosive Sublimate.
