Program Description
As Kohm & Spychalla LLC, we operate North America's first
private seed potato certification program.  We certify only
potatoes that we produce ourselves.

Our seed program defines "certification" as the description of a
seed lot's provenance and pathogen load.

The biology of each individual pathogen dictates our approach to
quantifying its' presence in a seed lot.  Over the course of the
next year we will be constructing a "Quality Manual" which will
describe the workings of our seed program as per the
APHIS/UDSA/PPQ State National Harmonization Program's
(SNHP) suggested template
