This Bartlett pear tree was killed by a severe blight at- 

 tack. The healthy trees in the background were not 

 infected. 



HOW TO CONTROL BLIGHT 



To control blight, prune out cankers and other 

 diseased parts, apply spray or dust, or do both. 

 The method you choose will depend on your loca- 

 tion, and on the extent of the blight infection. 



Pruning 



In late summer, inspect your trees and cut out 

 all blighted twigs. Make cuts at least 8 to 12 inches 

 below the diseased part of the twig. Cut out 

 blighted tissue in the large limbs and trunk: 

 extend the cuts well into healthy tissue. 



Inspect your trees again in late fall or early 

 winter, after the leaves are off and it is easier to 

 spot, cankers that you might have missed. 



Do not prune blighted blossoms and twigs in 

 the spring, except when only a few trees are lightly 

 infected. Postpone pruning until late summer or 

 early fall, when blight usually is no longer active 

 and the risk of spreading the infection is not as 

 great.
