CO SB137

Requires uncertified potato seed stock to be tested and approved by Colorado's certifying authority before planting, addressing the spread of Potato Virus Y in the state.

Allows growers to plant uncertified potatoes only if they were grown and stored as part of the grower's own farming operations, or if they are no more than one generation from certified parent potatoes and submitted for testing.

Mandates growers who intend to plant progeny from uncertified seed must submit the seed stock for testing and receive approval from the certifying authority prior to each planting in subsequent years.

Establishes that Colorado's potato industry plants over 52,000 acres annually, produces over 1 million tons, and contributes more than $335 million to the state economy, making disease control critical.

Takes effect 90 days after final adjournment of the general assembly, unless a referendum petition is filed, in which case it requires voter approval at the November 2024 general election.
