The National List identifies those synthetic substances that may be used and the natural substances that may not be used in organic crop and livestock production. It also identifies a limited number of non-organic substances that may be used in or on processed organic products. In general, synthetic substances are prohibited for crop and livestock production unless specifically allowed and non-synthetic (natural) substances are allowed for crop and livestock production unless specifically prohibited.
The proposed rule would:
- Add 16 substances to the list of those allowed in organic production and handling;
- Prohibit one substance (ivermectin) currently allowed in organic livestock production, because of the availability of less toxic alternatives;
- List a natural pesticide (rotenone) as prohibited to align with U.S. Environmental Protection Agency (EPA) regulations; and
- Change 17 substances already on the National List to reflect current farming or processing practices and needs.
