The National Organic Program (NOP) final rule (United States Department of Agriculture [USDA], 2000) defines organic production as a production system that is managed in accordance with the Organic Foods Production Act of 1990 and regulations to respond to site-specific conditions by integrating cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance, and preserve biodiversity. Certified organic growers use a wide range of IPM practices that comply with the NOP standards.
Section §205.206 of the NOP rule outlines the pest management practice standard. The rule states that a producer must use management practices to prevent crop pests, weeds, and diseases including but not limited to:
As stated in the rule, pest problems may be controlled through mechanical or physical methods including but not limited to:
Only when these practices are insufficient to prevent or control crop pests may an organic farm manager apply either 1), a biological or botanical material not on the National List of nonsynthetic substances prohibited for use in organic crop production (§205.602), or 2) a substance included on the National List of synthetic substances allowed for use in organic crop production (§205.601(e)–(f), to prevent, suppress, or control pests. However, the conditions for using the substance must be anticipated and documented in the organic system plan.
