| Polymer
seed film coating has been widely used in the seed industry for
cosmetic colouration, seed identification, and most importantly,
significant reduction of agrochemical dust-off of treated seeds.
In addition, there are increasing demands in providing seeds with
physiological benefits through polymer seed coating. SB2000, a
functional organic-based polymer developed by Seedbiotics, and was
tested on cold susceptible species, such as shrunken-2
corn, soybean, and dry beans. Beneficial responses were
measured in laboratory and field studies. |
Up
to 30% increase in cold test results and field emergence in cold
and wet soils was measured on selected crops. The polymer coating
retards imbibition during the first few hours of hydration, which
was attributed to reduced seed membrane damage and seed leakage
resulting in less imbibitional chilling injury.
