Final Rule Amends National List of Allowed and Prohibited Substances
USDA has published a final rule amending the National List of Allowed and Prohibited Substances based on public input and the April 2018 recommendations from the National Organic Standards Board. The changes allow elemental sulfur to be used as a slug or snail bait in organic production, to reduce crop losses. The final rule also allows use of polyoxin D zinc salt for organic plant disease control, and it reclassifies magnesium chloride from a synthetic to a non-synthetic substance. The final rule is effective November 22, 2019.
