HORMODIN A" 
A year ago Hormodin, the new root- 
forming chemical developed by the Boyce 
Thompson Institute for Plant Research, 
Inc., was a laboratory sensation. Today 
progressive seed dealers are finding it a 
profit sensation as well. 
A few tests will show your customers 
the amazing root-growing power of Hor¬ 
modin "A”. It enables them to obtain 
quicker and better rooting of cuttings in 
higher percentages than ever before. It 
enables them to hasten the development 
of slower rooting species—transplant some 
varieties directly from the bench to field 
conditions—propagate from cuttings 
many species that ordinarily do not root 
successfully. 
Hormodin ”A” comes in liquid form 
and is applied as a dilute water solution. 
The cost is only a fraction of a cent per 
cutting. To assure uniform root-inducing 
potency, every batch of Hormodin is 
standardized both chemically and phy¬ 
siologically. 
Free cuts for your catalog 
The demand for Hormodin is growing 
daily. Write today for new Hormodin 
"A” cut sheet and profitable catalog 
suggestions. 
Packed in five sizes, and sold on the basis of 
B. T. I. units of effectiveness.
