National Organic Program; Amendments to the National List of Allowed and Prohibited Substances (Crops, Livestock and Handling)

This final rule amends the National List of Allowed and Prohibited Substances (National List) provisions of the U.S. Department of Agriculture's (USDA's) organic regulations to implement recommendations submitted to the Secretary of Agriculture (Secretary) by the National Organic Standards Board (NOSB). This rule changes the use restrictions for seventeen substances allowed for organic production or handling on the National List. This rule also adds sixteen new substances on the National List to be allowed in organic production or handling. In addition, this final rule lists the botanical pesticide, rotenone, as a prohibited substance in organic crop production. This final rule removes ivermectin as an allowed parasiticide for use in organic livestock production and amends our regulations to allow the use of parasiticides in fiber bearing animals. Finally, this rule inserts corrections of instructions and regulation text as listed in the proposed rule.
