Dusting 
The Modern Method of Crop Protection. 
The rapid strides which the dusting method 
of crop pest control has made in the past five 
years is directly traceable to the efforts of the 
Niagara Sprayer Company. Its success, how¬ 
ever, has come because it has done those 
things which were claimed for it, and brought 
results by the most direct route. 
Dusts of infinite fineness have been perfect¬ 
ed, containing those properties necessary to 
kill insect pests and prevent diseases. Not 
only do the Dusts do the work done by liquid 
sprays, but their development has opened new 
fields of Crop Pest Control. 
Niagara Dusts are now being made that 
stick “through Wind and Rain” and exhibit 
toxic properties to many fungi and insects 
heretofore unequalled by either wet or dry 
materials. 
Niagara Dusting Material 
Dormant Dust. Delayed dormant dusting 
for San Jose scale, red mite and aphis on ap¬ 
ples, pears and shade trees. 
$10.50 per 100 lbs. 
Kolodust. A new dust developed by the Ni¬ 
agara Sprayer Co. It is sulphur fused with 
bentonite at high temperature and the product 
is koloized (a colloidal form). This produces 
a dust of infinite fineness much finer than 
300 mesh, which experiment stations have 
proven more toxic to fungous diseases than 
any sulhpur yet produced. 
$5.35 per 100 lb. bag.

stick. The New Exclusive Niagara Sulphur 
Fungicide with Lead Arsenate.

tent Dust suitable for dusting peaches and 
other stone fruits.

content. For use in orchards where peaches 
and apples are interplanted.

made an increasing demand for materials 
which kill chewing insects and yet may be used 
with safety.
