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, however, 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 perfected, 
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 devel¬ 
opment has opened new fields of Crop Pest Control. 
Niagara Dusts are now being made that stick 
“through Wind and Rain” and exhibit toxic prop¬ 
erties to many fungi and insects heretofore un¬ 
equalled by either wet or dry materials. 
Niagara Dusting Material 
Kolodust. A new dust developed by the Niagara 
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 rnuch finer than 300 mesh, which experi¬ 
ment stations have proven more toxic to fungous 
diseases than any sulphur yet produced.

Kololex. A Sulphur Poison dust that will stick.

Is the most recent addition to Niagara’s complete 
line of Dusts and Dusters. This great crop duster 
is a new machine in every respect—in design, con¬ 
struction and performance. 
Rotenone Dusts. Non-poisonous. Are the 
latest development in materials for use in the 
control of chewing insects. They have the addi¬ 
tional quality of leaving no objectionable residue 
at harvest time. The present restrictions in our 
arsenical residue tolerance have made an increasing 
demand for materials which kill chewing insects 
and yet may be used with safety.
