ting rid of the whitefly. I have no doubt 
but that the fungus will do away with 
the whitefly, but it does not remove the 
smut from the orange; that is one of the 
great drawbacks. 
Mr. Yothers: I do not like to enter 
into this discussion, except to correct the 
Reverend Glass in one statement. Per¬ 
sonally, I do not know anything about 
that gentleman he mentioned, and I nev¬ 
er heard of that spray of flour and water 
before. This is the first time it has been 
sprung on me. 
Mr. Glass: Then I am mistaken in 
the information. The gentleman told me 
he had been at Orlando at the Experiment 
Station, and I understood him to say that 
Mr. Yothers was there at that time, and 
they discussed it simply as a helpful agen¬ 
cy in the control of the whitefly, and in 
freeing the surface of the leaf from the 
covering of smut. Of course, the rain 
washed off the solution of flour and wa¬ 
ter. 
Mr. Stewart : In one of my groves 
that has the whitefly in it now, it was 
a mile from anybody’s grove, and the 
first time I discovered the whitefly on, I 
discovered the fungus there, too, and 
they have stayed together ever since. 
Some of my neighbors kept putting on 
these solutions—I do not consider them 
enough to get the names of them—and 
they were telling me the wonderful pro¬ 
cess of scaling off, like this flour pro¬ 
cess. I have gone to their groves, and 
to my own, which had no spraying ex¬ 
cept the rains from Heaven, and where 
the fungus has done its work, the rains 
will take the smut off. After the fungus 
has done its work, if you will leave it 
there, a few rains will loosen up the 
smut and wash it away. The fungus 
and the water of Heaven will do the 
work better than flour and water or any 
other solution. I have seen it done 365 
days in the year. 
Mr. Gaitskill: When we first heard 
about the whitefly in and around Mica- 
nopy and McIntosh, I got some fungus 
and put it in about a dozen trees where 
I saw the whitefly, and since then I have 
not gone to the trouble to put on any 
more. The whitefly does not attack a 
grove much ahead of the fungus. It 
follows of itself. I have not found any 
benefit of spraying fungus in the grove. 
I have known groves a mile from any 
other grove and the whitefly would go 
there and the fungus would get there 
directly after it and begin its work. 
Where I live we have concluded that it 
is useless, or, at least, unnecessary, to go 
to any trouble to put fungus in among 
the whitefly. It belongs with them, will 
get with them, and will stay with them. 
Mr. Dade: I have been watching it 
closely ever since we have had the white¬ 
fly, and I find by close observation that 
the insecticide does not hurt the fungus 
except by removing the whitefly. 
Mr. Hume: Which is its food. 
Mr. Dade: Yes, sir. 
Mr.- : jf the flour and water 
solution, as mentioned by the gentleman 
on my right, was sprayed on the leaves, 
would it not have the same effect that the 
smut has on the orange leaf? The smut 
simply stops up the pores on the orange 
leaf, and I should think the flour would 
do the same thing. 
Mr. Glass: In practical effect, the flour
