Dear Terry,
Several years ago we performed some, limited,
plant-oriented evaluations utilizing colloidal silver. Our initial
investigation involved experiments designed to determine if CS would yield
beneficial effects on "Fire-blight" associated with pear trees and
pyracantha shrubs. The only effective protocol we had found, prior to our
CS evaluations, was the application of streptomycin (water soluble form) in
an aerosol spray. A solution of 10 ppm strength CS mixed at the rate of 1
pint CS to 2.5 gallons of water and 1/4 teaspoon household detergent was
applied to affected trees (in various states of challenge, from 10% to 50%
foliage involvement). Visually detectable improvement manifested within 48
hours. Marked improvement and pathogenic stabilization evidenced within 72
hours. New leaf growth---in former areas of heavy attack---started to
appear within 7 days of the initial treatment. This protocol was repeatable
(we performed it 4 times).
We chose fire-blight because of its pernicious
nature and rapid progress on victim trees.
Our greenhouse evaluations did not reveal ANY direct
growth stimulation on ANY forbs/flowers/grass-like plants. Marked plant
general health improvements did occur in some cases......but were usually
directly traceable to the germicidal effect of the CS.....not to any direct
effect (detectable by us) upon plant metabolism or fertilizing phenomenon.
To attempt to market colloidal silver as a plant
fertilizer or direct growth stimulant (in its own right) would be, in my
estimation, a very risky endeavor---unless you had (in hand) documented and
repeatable evidence to verify such claims.
I wish you well in your endeavors to increase the
useful applications of colloidal silver. Sincerely, Brooks Bradley.
