PLANT HEALTH
GROUND RULES
SETTING
Regulation could mean better understanding of
biostimulant benefits and performance
BY DEAN PETERSON
B
iostimulants have long been unregulated inputs in
the U.S. This has allowed hundreds of them to come
to market lacking levels of quality control, thirdparty
testing and other user-oriented information on use
and efficacy.
Some individuals and groups pushed for change and
more rigor in grower-friendly documentation.
" As many have said and written, the bill contained the
first legal/statutory language about plant biostimulants
of any law in the U.S., " said Matt Kleinhenz, Extension
specialist at the Ohio State University's Department of
Horticulture and Crop Science. " It kick-started a process
ultimately aimed at improving farmers' experiences with
plant biostimulants. "
The Biological Industry Alliance at bpia.org is a good
resource to track new developments.
" A new era has opened up, " Kleinhenz said.
Kleinhenz and his team at OSU used USDA SARE
(Sustainable Agriculture Research and Education) funding
to do some of the early research on biostimulants.
There are hundreds of biostimulants on the market and
they fall into various categories, mostly depending on
their origin or what they contain.

Symbiotic bacteria, symbiotic fungi and humic
and fulvic acids derived from compost are examples
of biostimulants. Seaweed extracts are used as
biostimulants. Protein hydrolysates, which are peptides
or amino acids derived from plant or animal products, are
also examples of biostimulants.
The definitions and properties of biostimulants
frequently overlap.
Biostimulants listed by OMRI for use in organic
production are also widely used in conventional
agriculture. They are used both in specialty crops and
field crops, as well as field production, greenhouses and
high tunnels, and soil-based and soilless media.
Some biostimulants are advertised as products to
increase yield and improve crop quality. Others are
touted to reduce susceptibility to disease and enable
plants to better tolerate other sources of plant stress.
The list of other touted advantages is long.
The key to selecting a biostimulant? " Know what the
product is and what the desired effect is, " Kleinhenz said.
Is it to improve the greenness of a vegetable crop for
improved visible appearance or to increase a field crop's
total marketable yield?
