be the most promising preparation. This may be obtained 
by using the commercial solution at the rate of 1% gallons 
to 50 gallons of water, or by boiling the mixture at home and 
diluting it so that each 50 gallons will contain 4 lbs. of sul¬ 
phur. At this strength neither the commercial nor the 
home-boiled solution materially injured apple foliage in the 
experiments which we conducted last year. If the results 
of these experiments could be taken as a reliable guide there 
need be no hesitancy in using this mixture, but under differ¬ 
ent conditions the results might be different and the matter 
must still be considered as more or less experimental. In 
our experiments the commercial solution at a strength of 2 
gallons to 50 gallons of water injured apple foliage rather 
seriously and it should not be used stronger than 1 y 2 to 50. 
Our experiments of 1908 and 1909, as well as the pub¬ 
lished records of other investigators, show that the lime- 
sulphur solution is apparently as effective as Bordeaux mix¬ 
ture in the control of apple scab. In experiments which we 
conducted in Virginia the disease was held down to less than 
1% of the crop by three sprayings with the lime-sulphur 
solution (2 to 50), while 30% of the unsprayed fruit was 
scabby. In Michigan, four applications of the same solution 
held the scab down to about 5% of the crop while 81% of 
the unsprayed fruit was scabby. It will control the apple 
leaf-spot and other minor troubles as well as apple scab, but 
so far it has not proved to be a satisfactory remecfy for 
apple blotch (Phyllosticta) and bitter rot. In sections 
where spraying for bitter rot is required, the lime-sulphur 
treatment for scab and leaf-spot could be followed by 
applications of Bordeaux for bitter rot. 
The results of experiments so far indicate that arsenate 
of lead is the poison to use with the lime-sulphur prepara¬ 
tions. Instead of increasing the caustic properties of the 
mixture, as at first feared, it apparently has the opposite 
effect to some extent and does not lose any of its insecticidal 
value by reason of the combination. In all of our experi¬ 
ments last year the combination of Paris green and the lime- 
sulphur solution proved to be quite injurious to apple foliage 
as did also the combination of arsenite of lime and lime- 
sulphur. 
ARSENICALS IX LIME-SULPHUR MIXTURES 
From the Popular Edition of Bulletins Nos. 319 and 320 of the New York- 
Agricultural Experiment Station, Geneva, N. Y., by L. L. Van Slyke and 
P. J. Parrott. 
The advisability of combining arsenicals with sulphur sprays has 
not yet been conclusively determined; but present studies indicate 
that such poisons may be combined with lime-sulphur solutions. In 
spraying for blister-mite, arsenate of lead, or arsenite of lime in the 
usual quantities may be combined to advantage with the lime- 
sulphur wash for the purpose of controlling budmoth and case- 
bearers, which are now quite destructive in many orchards. In pre¬ 
paring the arsenite of lime, two pounds each of white arsenic and 
salsoda crystals are boiled until dissolved, about 15 minutes, in a 
gallon to a gallon and a half of water. Use the solution to slake 
three or four pounds of good stone lime and when ready for use add 
water to make two gallons and stir thoroughly. A quart of the 
mixture will then contain cne-fourth pound of the combined white 
arsenic, in form of the safe arsenite of lime, and be equal to a half 
pound of paris green.
