mulch the trees and cease cultivating, 
the Bordeaux proves a complete cura¬ 
tive of the red rust. An application of 
it, and then repeat it in ten days, would 
cause the scaliness to be cleared off and 
the fruit made shipable; but at the same 
time where we spray with the Bordeaux 
mixture we should follow it in a short 
time with something to destroy scale. If 
it were followed by a spray as an insecti¬ 
cide we should not have the scale. It 
was not of my origination at all; it was 
simply my following out of another’s 
ideas. 
Mr. Hardee—I have used the Bor¬ 
deaux mixture. Mr. Froscher wanted 
me to use it to introduce it. I had such 
little confidence in any application of the 
kind that I declined to use it, believing 
that it was a root disease entirely. I 
mulched some of my trees, others I could 
cultivate, but the dieback seemed to get 
worse. Mr. Porcher, who had used the 
Bordeaux mixture as prepared by Mr. 
Froscher, after he had tried it, told me 
how to use it. I prepared it and used it 
and I must confess this: I did not have 
much confidence in it, but after the first 
application I put on the trees, when the 
fruit was about half grown, it instantly 
stopped the cracking, and I was so well 
pleased with the application that I gave 
it a second time, and many of the trees 
that were inclined to crack were cured. 
I would say that the Bordeaux mixture 
is a very good cure for dieback. But it 
must be followed by an insecticide to kill 
scale. I have a number of neighbors 
around me that have also used the mix¬ 
ture, and there is not one of them that I 
have talked with but who was well 
pleased with the result, but they all agree 
that it must be followed up with some in¬ 
secticide. I made only two applications 
to my trees, I think twenty or probably 
twenty-five days apart. I used the rosin 
wash afterwards. 
Mr. Porcher — Bordeaux mixture 
should not be used too often; three ap¬ 
plications in twelve months would be 
sufficient. Four pounds copper sulphate 
to six of lime, so as to give plenty of 
lime. The mixture wants to be used as 
quickly as possible after being made. 
Mr. Hubbard—Has the Bordeaux 
mixture any effect on the flavor of the 
fruit ? 
Mr. Porcher—None at all. 
Mr. Butler—Of course, when we all 
heard what Mr. Froscher’s mixture was, 
we believed it to be contrary to our 
ideas, but the word of an honest man is 
sacred, therefore I used it. I sprayed 
ten acres that was beginning to have a 
little dieback and it helped them. I also 
believe that it has a tendency to cure 
rust. 
Mr. Porcher—When this question of 
Bordeaux mixture came up I wrote to 
the Department at Washington and they 
replied that their investigation showed 
that our trouble was unquestionably a 
sap trouble; in other words that it came 
from the root. You can take a tree up, 
remove it to another location and it does 
not have the red rust. I state that it is 
a fungous trouble which is corrected by 
this mixture. The Department will tell 
you that it is not a fungous trouble. They 
will also tell you the Bordeaux mixture 
is a fungicide. I don’t know what more 
to say, save that I have had good results 
with Bordeaux mixture. 
I have corresponded with many and 
I can find in no case a man who will give 
any explanation beyond the fact that 
possibly there were ulterior things that 
have helped us out.
