The production of high quality seed potatoes within the state requires conditions that are as free as possible from insect pests and plant diseases. The production of other potatoes intermixed with or in close proximity to a concentrated seed potato production area poses an increased risk of introduction of insect pests and plant diseases. To mitigate this problem this chapter establishes a seed potato isolation district requiring commercial potato production within the boundaries to be enrolled in the seed potato certification program.
