Efficacy Requirements for Antimicrobial Pesticides

In addition to data requirements that apply to all pesticides, pesticides designed to control microbial pests such as viruses and bacteria must have data proving their ability to kill these pests (known as efficacy).

Each of the guidance documents listed below provides a summary of current efficacy-related requirements and/or policy for a category of antimicrobial pesticide products, claims, or patterns of use. If more detailed guidance is needed, the Antimicrobials Division should be consulted. 

If any of the product's use patterns is classified as human-health-related, efficacy data must be submitted for review in order to support the inclusion of that use pattern in the product registration. Regardless of the use pattern, however, product efficacy data is required to be maintained in the registrant's files.

Requirements to develop data on product performance provide a mechanism to ensure that pesticide products will control the pests listed on the label and that unnecessary pesticide exposure to the environment will not occur as a result of the use of ineffective products. Specific performance standards are used to validate the efficacy data in the public health areas, including:

  • disinfectants used to control microorganisms infectious to humans in any area of the inanimate environment; and
  • those pesticides used to control vertebrates (such as rodents, birds, bats, and skunks) and invertebrates (ticks, mosquitoes, etc.) that may directly or indirectly transmit diseases to humans. 

The key set of documents directing efficacy testing is:

In addition, the following documents also provide information relevant to the efficacy process:
