3. What will labor and material cost to 
spray 5000 medium sized orange trees\? 
Mr. Connor.—During the last three 
weeks I have had some experience in this 
line, just the experience fruit growers 
would have who have not the complete 
apparatus for spraying. The cost of spray¬ 
ing for about 500 tr^es was something 
over $7.00, with an additional cost of 
$8.00 for material used, or about $15.00 
which would be an average cost to depend 
upon. Trees bearing from two to four 
boxes. 
4. Will whitewashing orange trees 
with pure carbonate of lime be detrimen¬ 
tal ? 
Mr. Hart.—I remember twenty five or 
thirty years ago there was quite a discus¬ 
sion in regard to whitewashing orange 
trees. In California several years ago I 
saw where they had cut back their trees 
to bud them, and that they had white¬ 
washed the trunks eight or ten feet high 
to protect them. This might be all right 
but I remember there were objections 
found to white-washing but they have 
gone out of my mind just now and I can¬ 
not state them. Perhaps Maj. Fairbanks 
can give us something on this line. 
Maj. Fairbanks.—I wish to say that I 
have no information whatever. I like the 
orange tree and think it is the most beau¬ 
tiful tree in creation and it is a sacrilege 
to white-wash it. 
Mr. Painter.—Anything put on the 
orange tree to cover up its pores is in¬ 
jurious, especially during the growing 
season. White-wash your fence and out¬ 
buildings but wash the trunk of your 
trees with water and whaleoil soap. 
5. I have Mexican clover in my grove 
and would like to know how to get it out. 
Maj. Healey.—Let more of it grow and 
you will not want to get it out. 
Mr. Painter.—I would suggest that if 
he really wants to get rid of it he move to 
another county. 
6. Explain how, when and what quanti¬ 
ty of blue vitriol to use for dieback. 
Mr. Brown.—I suppose that the regu¬ 
lar Bordeaux formula would be used; it 
should be used just previous to the start¬ 
ing of new growth, I should say the latter 
part of January, but it could be usejl later 
in the season. If the tree is in a very bad 
condition, inoculate the tree, but my plan 
is to use a spray. 
Mr. Longley.—I would like to know 
what quantity to use in this inoculation. 
Mr. Brown.—I use a quantity about 
equal to that of the size of a pea inserted 
risfht under the bark of the tree. 
7. What is the best remedy for foot 
rot? Is it best to resort to remedies for 
the cure of this disease, or pull out the 
tree and plant a new one. 
Mr. Phelps.—Some time prior to 1895 
I set out ten trees. I found this foot 
rot on them later. I happened to meet 
Mr. M. F. Robinson who advised me to 
apply sulphuric acid to the ground and 
rake it in well, this I did and the very 
worst tree I had came out fine, in fact 
better than any of them. 
I should dread very much pulling up a 
tree as it is no little job, and shall do 
everything I can to save them otherwise 
and l have saved a good many so far; 
I still believe in the sulphuric acid well 
raked in.
