NOP Changes to Allowed and Prohibited Materials in Organic Crop Production

NOP Changes to Allowed and Prohibited Materials in Organic Crop Production

Some changes have been made to the Organic Standards including the materials allowed for use in organic crop production. The following updates to the Organic Standards will be fully implemented on January 28, 2019.

Rotenone will be added to 205.602 making it prohibited for use in organic crop production.

The restriction on micronutrients has changed, now allowing for alternative methods for documenting a deficiency to include such methods as tissue testing, no longer limiting it to only soil testing. BOC already accepts tissue testing in some cases and will continue to do so.

New allowed crop materials (added to 205.601):

  • Magnesium oxide - for use only to control the viscosity of a clay suspension agent for humates.
  • Squid by-products - from food waste processing only; can be pH adjusted with sulfuric, citric or phosphoric acid. The amount of acid used shall not exceed the minimum needed to lower the pH to 3.5.
  • Hypochlorous Acid - as a chlorine material use as an algicide, disinfectant, and sanitizer; must be generated from electrolyzed water.
