new root-inducing chem¬ 
ical that stimulates 
rapid root growth on 
leafy cuttings, being es¬

TRI-OGEN 
Reg. U. S. Pat. Off. 
The ali"purpoHe spray 
An insect spray and fungicide 
for garden and greenhouse 
plants. Especially recommend¬ 
ed as a rose-garden spray treat¬ 
ment for mildew and black spot. 
Tri-ogen will also control al¬ 
most every insect pest and dis¬ 
ease that attacks the rose. It 
stimulates plant growth; it is 
harmless to foliage or blooms; 
and the fact that it does three 
separate jobs in one spraying is 
perhaps the reason for its great 
and ever-increasing popularity. 
Tested and used by rose and 
plant growers the world over.

ADVANTAGES OF HORMODIN "A" 
Hormodin hastens the rooting of cuttings to much less than nor¬ 
mal time, assuring quicker and better rootings in higher percentages 
than ever before pos¬ 
sible. This saves space 
on the propagating 
bench, time and money. 
Hormodin often permits 
transplanting some va¬ 
rieties of cuttings di¬ 
rectly from the bench 
to field conditions. Be¬ 
cause Hormodin induces 
roots to grow directly 
from the plant tissue, 
cuttings may be taken 
without relation to buds 
or nodes.
