I believe I can answer this most easily with a short excerpt from my  
book , The Pruning Book:

	. . . Marketing or, perhaps, an innate desire for nurturing has  
induced humans for centuries to cover wounds with dressings ranging  
from clay to manure to tar. Such dressings, for the most part, keep  
the wound moist, maintaining a hospitable environment for disease- 
causing microorganisms. (Exceptions exist: a particular dressing  
might be useful because it contains hormones to prevent resprouting,  
or insecticides to fend off borer attack on susceptible plants such  
as elm and pecan.) . . . A good pruning cut -- not a poultice --  
allows a woody plant to seal off the wound and prevent spread of  
infection. Take care in how you cut, and appreciate the plant's  
natural ability to heal itself.
