EffecTEST Biochemical Assay

EffecTEST is a post-treatment aquatic plant biochemical assay which assesses the current status of herbicide treatment programs. Tissue samples from a treated water body are gathered, processed and analyzed at the SRTC to determine the level of herbicide injury in those plants. SePRO and resource managers utilize these data to assess treatment status and make adjustments to treatment protocols as needed to achieve desired plant control.

Please contact your SePRO Technical Specialist for more information about designing a monitoring plan.


Effective immediately, cooperators shipping plant samples to the SePRO aquatic laboratory in North Carolina MUST include a copy of the USDA's Animal and Plant Health Inspection Service (APHIS) permit with their shipment. In order to comply, SePRO will be unable to accept packages containing plants that are not accompanied with this permit.
