Application rates and timing should be based upon the treatment site location and prescription guidance provided
by your SePRO Technical Specialist for the ECOS Preventative Aquatic Weed Control Program. The SePRO
Performance Assurance Guarantee is not designed for ponds with constant flow causing a turnover time of less than
14 days and does not include control of the following species: floating aquatic plants, cabomba, Illinois and largeleaf
pondweed, hygrophila, spike rush, vallisneria, rooted-floating plants, water chestnut, or algae. For ponds with
an average depth greater than 4 feet, an additional quantity of product will be required. This is specific guidance
for SonarOne® — modification of formulation may impact results and should be discussed with your SePRO Technical Specialist.
If acceptable weed control is not achieved additional material will be provided as part of the Performance Assurance Guarantee. Simply email a copy of this document, a copy of the invoice for the SonarOne (based upon the acres described above) and example photos* of the problem to ECOS@sepro.com. Products will be shipped to provide control of nuisance weeds and maintain control through the remainder of the season for 10% of the ponds designated above.
If additional product is needed beyond the first shipment simply e-mail a copy of this document, a copy of the invoice for the SonarONE (based upon the acres described above) and example
photos* of the problem to ECOS@sepro.com. Precipitation Clause: The Performance Assurance products will cover up to 20% of the acres, if precipitation is 20% above average during the treatment period.
