Combined Spray Treatment 
Fungicide — Insecticide — Plant Stimulant 
Complete Protection against Plant 
Insects and Diseases 
In the past. Mildew and Black Spot have been most 
difficult to combat. However, these diseases are now 
easily controlled with the Tri-ogen Spray Treatment, 
which gives COMPLETE protection against all diseases 
and insect pests. It is easily applied and also acts as 
a plant stimulant—producing vigor in growth with 
resultant luxurious blooms, heretofore considered im¬ 
possible. The Tri-ogen Spray Treatment applied weekly, 
from early season until late frost, makes it possible 
for the amateur to achieve the success, in many cases, 
comparable to the professional grower. 
TRI-OGEN was officially adopted for the exclusive 
protection of the Garden of 6000 Roses, at the 
CENTURY OF PROGRESS, Chicago World’s Fair.
