Seed Coating Technology
There are seed amendment technologies which are applied in
conjunction with “seed treatments” (Seed Applied
Fungicides – SAF, Seed Applied Insecticides – SAI,
Biological Crop Input Products – BCIP) which
complement the use and function of those seed
treatments (SAI/SAF). The amendments are coatings
composes of polymers combinations which are applied
with seed treatments and become integrated with the
SAI/SAF/BCIP to coat the seed.

Innovation and Opportunity:
 Rates of new coating technology can dramatically reduce fugitive dust
from current low levels but application may be high and may slow seed
treatment throughput or require a drying system. But further reduction of
dust levels can be achieved at lower rates of new coating.
 Handing the decision back to seed supplier to provide target flexibility –
the equipment exists to allow for tailored seed enhancement decisions.
 New seed coatings in combination with advanced SAF/BCIP technology
which enhance seedling and plant health may open candidates for SAI
consideration
 Seed coating technology exists and is evolving to further complement the
use of seed SAF/SAI on numerous crops to enhance product retention,
improve seed flow, seed plantability, optimizing seed placement and while
contributing agronomically plant populations.
