Colorado Seed Potato Act

Colorado Seed Potato Act (35-27.3 C.R.S.) Legislative Declaration: The General Assembly hereby finds and declares that the purpose of the article is to control and minimize the spread of contagious community diseases by reducing the overall inoculum pool present in potato crops. This article is further intended to comply with the seed potato standards set forth in the state national harmonization program.

The Colorado Seed Potato Act regulates the distribution and planting of seed potatoes. All seed potatoes distributed by any person in lots that are sufficient to plant one or more acres in Colorado must be certified. You can discover how to obtain a copy of the Seed Potato Act here.

Colorado farmers grow almost 60,000 acres of potatoes each year. About 10,000 of these acres are for certified seed potato production. The San Luis Valley and Northeastern Colorado represent the regions where potatoes are grown. Most of the potatoes produced are sold on the fresh market for consumption. Colorado also has the largest percentage of potatoes exported to Mexico in the U.S..  The value of the crop is almost $200 million per year. Seed Potatoes imported into the San Luis Valley must meet the requirements of Colorado's quarantine for Late Blight. You can read details on the quarantine for Late Blight here.
