LIME-SULPHUR MIXTURES FOR SUMMER SPRAYING. 11 
pounds of sulphur and the same amount of lime would probably be 
about right, although a mixture of this strength has not yet been 
tried. 3 
From Tables I and I1 it seems evident that scab may be completely 
controlled and brown-rot held in check to a large extent by three appli- 
cations of the self-boiled lime-sulphur mixture. Mr. Aldrich says in 
regard to the work on his place: “ 
The fruit on the 50-50-250 part showed up almost without a blemish, and you can 
only realize how apt that expression is, ‘‘as pretty as a peach,’’ when you have a crop 
of perfect fruit. The 30-30—250 had some scab—just a little—while the check rows 
were comparatively worthless; would not pay even picking expenses if they were 
given to you. They could not be recognized as the same varieties, although the 
trees stood side by side. Even if this spray was good for nothing else but the scab, 
no peach grower could afford to go through the season without using it. 
EXPERIMENT IN ARKANSAS. 
Similar experiments were conducted at Bentonville, Ark., and the 
results were about the same as those obtained in Georgia and Ili- 
nois, though perhaps not quite so favorable. A feature of the 
Arkansas work worthy of mention is the effect of the treatment on the 
San Jose scale. One of the orchards treated was so badly infested 
with this insect that at picking time the unsprayed trees were almost 
bare of foliage, the twigs and some of the limbs were in a dying condi- 
tion, and the fruit was shriveled and worthless, due to the combined 
effect of the scale and the scab. Owing to the dried condition of the 
fruit, brown-rot did not develop to any serious extent. On the other 
hand, the sprayed trees which received four applications of the self- 
boiled wash remained in full foliage and yielded a fair crop of good 
merchantable fruit, the scale apparently having been held under 
control. 
FRUIT STAINING. 
An objectionable feature of the self-boiled lime-sulphur mixture is 
its whitewashing effect on the fruit. This is very noticeable when an 
application is made shortly before the fruit ripens; but if the last 
treatment is made about a month before picking time, the stain 
mostly .weathers away and does not materially mar the appearance 
of the ripe fruit. However, it is objectionable and must be taken into 
consideration. 
RECOMMENDATIONS FOR THE TREATMENT OF SCAB AND BROWN-ROT. 
For the combined treatment of peach scab and brown-rot, at 
least three applications are necessary; the first, three to four weeks 
after the petals drop, the last about a month before the fruit ripens,
