Dusting 
The Modern Method Of Crop Protection 
The rapid strides which the dusting method of crop pest control has made in the 
past four or 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 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 unequaled by either wet 
or dry materials.
