Gravity® PGS
Plant growth stimulator
Plant Growth Stimulator
Gravity® PGS, a unique blend of plant growth hormones, is
designed to stimulate root growth and plant health in new
seedlings, transplants and existing plants. Gravity® PGS
contains Cytokinin, Gibberellic acid and Indole butyric acid
(IBA). Cytokinin is a natural plant hormone that promotes
cell division while slowing leaf aging. Gibberellic acid is
a naturally occurring plant hormone that stimulates cell
division. Indole butyric acid (IBA) is a plant hormone that
stimulates vigorous root formation and development.
Gravity® PGS greatly assists seed germination and cutting/
sod/seed establishment. Also available as a coating on
turfgrass seed.

Clipping Production
Seed Germination
Gravity® PGS (0.1 fl oz per 1000) and 46-0-0 (0.125
lb N per 1000) were applied to a creeping bentgrass/
annual bluegrass putting green. Clipping production was
evaluated 7 days after application. Gravity® PGS treated
plots did not substantially increase clippings compared
to the untreated plots and produced fewer clippings
than 46-0-0 treated plots. Research conducted by Steve
McDonald, Turfgrass Disease Solutions, 2013.
Seed germination of Gravity® PGS treated seed was
compared to untreated seed. Kentucky Bluegrass seed
treated with Gravity® PGS had significantly faster initial
germination and had more total seed germination.
Tall Fesuce, Creeping Bentgrass, and Chewings Fescue
treated seed exhibited similar results. Research
conducted by Dr. Brian Horgan, Dr. Eric Watkins and
Andrew Hollman, University of Minnesota, 2012.
