Marshall- I add the Cs to a SOLO backpack 4 gallon sprayer mixed usually with 
Malthion and regular water.  Then I spray the needles of the tree or the root 
area and trunk if the tree has a root rot.  Usually I mixed 4 ounces of Cs to 
the 4 gallon tank.  Last year I was making Cs at 8 ma and this mix seemed to 
be helping.  This year I shut off at 4 ma and still have lots of sick trees.  
The trees with rust still have rust.  The rust is said to be spread by 
cottonwood trees like Poplars.  I was thinking of going back to 8 ma Cs for 
tree spray.  I use well water for the Cs tree spray.  When I cut out a sick 
tree I spray the stump with Cs using a Wall Mart spray bottle.

Last year a well to do Lady came to see me in April just after I returned 
home from Arizona.  She asked if I would settle an argument with her husband. 
 She asked me how to tell if a cut tree is dead.  I told her when the needles 
dry and fall the tree is dead.  Her husband wanted to take the tree down and 
burn it!  She said it is still living because it still had its needles!  I 
suggested she get her husband to dig a hole in the garden and plant the tree 
to allow it to die naturally, at least he could get the tree out of the 
house.  She did not want him to burn the tree while it was still alive.
