PlanTEST Bioassay

PlanTEST is a pre-treatment aquatic plant bioassay that determines the susceptibility of plants to aquatic herbicides. Pre-treatment plant samples are gathered from a water body and processed at the SRTC. SePRO uses assay results in developing site-specific treatment prescriptions.

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.

Please download and print this permit by clicking the icon below and enclose it in your package. If you have problems opening the attachment, please contact your Technical Specialist or the laboratory and we will fax you the permit. Thank you for your cooperation.
