APP-L-SET 
When sprayed on the apple stem, this chem- 
ical compound tends to hold the fruit on the 
tree for a longer time, greatly reducing losses 
from wind, and to a great extent, eliminating 
“spot picking.'’ App-L-Set (Dry Mix) is recom- 
mended for use at 14 lb. per 100 gallons 
of water, with which it mixes easily and 
quickly. This small amount of material will 
not spot your fruit or leave any objectionable 
residue. 
Postpaid, 4-lb. can, $1.25. 
MIKE WETTABLE SULPHUR 
A trade name for the new Microscopic extra 
fine prepared sulphur. Mixes readily with 
waier in combination with Lime, Arsenate of 
Lead, etc. Mike Sulphur is one of the finest 
and best materials of its kind, as it really 
stays in suspension and therefore gives the 
needed results. 
Postpaid, I1-lb. can, 40c; 
10-lb. bag, $1.55. 
HYDRATED LIME 
For mixing with Sulphur in making dry mix 
or home-boiled Lime-Sulphur and for mixing 
with Bluestone (Copper Sulphate) for making 
home-made Bordeaux; also used for sweeten- 
ing an acid soil in flower and vegetable gar- 
dens, and for mixing with sprays where Ar- 
senate of Lead is used. 
Postpaid, 10-Ib. sack, 50c. 
ORTHO SPREADER 
In dry form and is designed primarily for 
use with Arsenate of Lead and Lime Sulfur 
solution. As the name implies, Ortho Spreader 
functions to provide more effective film cover- 
age for Arsenafe of Lead. It also provides 
buffering action through protective colloids, 
making it possible to reduce Hydrated Lime 
diluent effect to a minimum. This same col- 
loidal action buffers the action between Ar- 
senate of Lead and Liquid Lime Sulfur, largely 
preventing the formation of black sludge (Lead 
Sulphide) in the tank, and reducing danger 
from the combination. The low dosage of 
Spreader required (1 to 2 lb. per 100 gallons) 
makes its cost negligible. This Spreader has 
practically replaced all other types of popular 
dry spreaders over the past eight years.

APPLE DRITOMIC SULFUR 
A fungicide made distinctly for the apple - 
spray schedule, beginning at pink or cluster © 
bud and continuing throughout the summer ~ 
for control of scab and other fungous diseases 
controllable with a Sulfur fungicide. As a 
scab spray, Apple Dritomic Sulfur possesses 
greater fungicidal potency than ordinary all- — 
purpose wettable sulfurs. This is due to the 
additive value imparted to Apple Dritomic — 
through its 15 per cent of sodium thiosulfate, — 
which activates and reinforces the 82 per 
cent of extremely fine elemental sulfur con- 
tent. Apple Dritomic Sulfur is non-caustic, 
and will not injure foliage if used as di- 
rected. Six pounds of Apple Dritomic Sulfur 
makes 100 gallons of spray. Complete direc- 
tions on each package.
