Columbia Food Laboratories’ people have experience analyzing potatoes as far back as 1970. We currently have two multi-residue screens (profiles) especially for potatoes. The P2400 is a low cost profile designed primarily for domestic product, and, the P2401 is for product exported to Japan. Also available are individual analyses for pesticides not extractable by a multi-residue screen, but which are known to be used on potatoes. The following information is available by calling or e-mailing us:

  • P2400 Potato Pesticide Profile
  • P2401 Potato Pesticide Profile, Expanded
  • Price list for pesticides commonly used on potatoes
    (includes listing for P2400 & P2401 as well as individual tests)
  • Customized profiles can be designed upon request

Sprout Inhibitors
We can monitor the sprout inhibitor level in potatoes for CIPC,
diisopropylnaphthalene, 1,4-dimethylnaphthalene and clove oil (as eugenol).
