AT LAST IT HAS BEEN PROVEN 
Laboratory tests at the University of California have shown that strep- 
tomycin, an anti-biotic derived from favorable bacterial mold, is effective in 
treating seeds infected with bacterial diseases. In their extensive tests this 
anti-biotic gave excellent control of tomato seed infected with bacterial speck 
and canker. Limited experiments in the field also were encouraging. 
NOTHING NEW—Nature has been using this system of seed treatment 
for thousands of years. GLECKLERS: Seedmen, have been extracting seed 
from rotten tomatoes for several years. Full details were given in our 1951 
catalog. In the natural rotting of the tomato, anti-biotics are created, treat- 
ing the seed for any seed-borne diseases that may be present. Most every- 
one has noticed the presence of white mold on rotten tomatoes, which is the 
visual indication of anti-biotical action. 
WE HAVE ALSO FOUND in our tests that the pulp and juice of tomatoes 
are very high in phosphorous content. It is already known that seeds are 
mainly made up of the same element. It is likewise most certain, during the 
rotting process, the seed absorbs additional phosphorus in fortifying itself 
for future propagation. 
ANOTHER TREATMENT takes place during the rottening process—a 
system of SURVIVAL OF THE FITTEST. Through this grueling treat- 
ment weak seeds, which produce subsequent plants of low vitality, subject 
to disease and low yields, are prevented from germinating. SURVIVAL OF 
THE FITTEST has been the common rule to all forms of life down through 
the ages. 
ADDITIONAL PROOF of the effectiveness of anti-biotics in seed treat- 
ment has been shown in tests at The Wyoming Agricultural Experiment 
Station. Recent tests there have shown streptomycin to be very effective in 
treating seed beans for bacterial blight. Former control was mostly by the 
troublesome hot water method.
