GenTEST* Aquatic Plant Genetics Assessment
GenTEST is an advanced assessment technology that examines specific genetic sequences of aquatic plant DNA (deoxyribonucleic acids) to predict response to management with aquatic herbicides. Using the GenTEST, resource managers have improved confidence in the outcome of management activities and practice the highest level of stewardship in the management of aquatic plants. Please contact your SePRO Aquatic Specialist for more information about designing a monitoring plan.

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 utilizethese data to assess treatment status and make adjustments to treatment protocols as needed to achieve desired plant control.
