marked difference all the way through, 
between sprayed and unsprayed fruit. 
Mr. Skinner: Somebody here wants 
to know whether that was soda sulphur 
or lime sulphur? 
Mr. Stevens: Most of the spraying 
was done with sulpho-citrol, which is a 
lime-sulphur spray, at one to one hundred. 
There were seven rows, about five acres, 
sprayed with soluble sulphur, and there 
was a check made there, also. The sol¬ 
uble sulphur kept the fruit bright. 
Mr. Brown; Let me ask how many 
pounds of the soluble sulphur you used 
to ioo gallons of water. 
Mr. Stevens: I cannot be really posi¬ 
tive, but the first spraying we used 50 per 
cent stronger than the printed recommen¬ 
dations; that is, I think, three pounds to 
a hundred. After that, it was two pounds 
to a hundred. With the first spraying, 
we hoped to control the melanose. We 
have had none this year to speak of, any¬ 
way, so it did not make much difference. 
Mr. Hollingsworth: Did you ever use 
air slacked lime for the same purpose on 
the land? . 
Mr. Stevens: Yes, a portion of the 
grove has been limed. Where we used 
the lime we had more rust this year. But 
we did not lay it to the lime. 
Mr. Stevens: The tree from which 
that pile of unsprayed fruit was taken 
was a healthy tree; not diseased. In fact, 
the four rows were not diseased. As I 
have stated in the beginning, the whole 
crop of fruit was badly infected with this 
shark skin. The spraying we did simply 
eliminated the shark skin. Now every 
tree of the 84 has fruit just like that, and 
I believe that if we had done no spraying 
127 
this year, 90 per cent of the trees would 
have been affected this year. 
Mr. — —: I have owned a small 
grove for five years, and it has never been 
sprayed and we never had any such fruit 
as that. It is as good as the other, but 
not so bright. 
Mr. Yothers: I had some of that fruit 
at the Orange county fair, and about 20 
per cent of the people said it was a fake 
exhibition. 
To my mind, that experiment is de¬ 
cisive, and I really feel that my work in 
that respect is done. But of course, we 
have to- continue with that line of work. 
I also had the good fortune to co-operate 
with one of the very best growers in the 
state, Mr. Williams, of Crescent City. So 
far as I know, he is not here. 
In my own opinion, this work at Cres¬ 
cent City was one of the very best and 
most clear cut demonstrations that has 
ever been conducted in the state of Flo¬ 
rida. 
We left one row unsprayed for two 
years and on both sides of this one row 
the rows were sprayed. When the fruit 
was picked, 1915, we got about five boxes 
of fruit from the unsprayed row, and ap¬ 
proximately sixty boxes from the rows 
twenty-five feet away. The fertilization, 
cultivation and pruning was all the same 
for all trees. I am sorry that Mr. Wil¬ 
liams is not here, because I feel if he were 
here to tell you those things himself, it 
would make considerably more of an 
impression. It should be remembered that 
the beneficial fungi were present on both 
sprayed and unsprayed trees. 
Mr. Skinner: Mr. Yothers made this 
statement up at Gainesville, and gave an
