A final rule to amend the National List of Allowed and Prohibited Substances for organic crops recently was published in the “Federal Register.” There are three amendments to the rule.

  • allows elemental sulfur to be used as a slug or snail bait to reduce crop losses
  • allows polyoxin D zinc salt for plant-disease control
  • reclassifies magnesium chloride from a synthetic to a non-synthetic substance

The final rule is effective Nov. 22. Visit and search for “2019-23035” for more information.
