EPA Workplan: Demonstration Project on Hydrilla and Hygrophila in the Upper Kissimmee Chain of Lakes

Element 1: Development and Testing of New Aquatic Herbicides

1. Determination of field efficacy, selectivity, and water residues of at least seven herbicides new to aquatic use.

2. Testing of a minimum of fifteen compounds and/ or combinations of compounds for activity against hydrilla.

3. Determination of Concentration Exposure Times (CET) of at least six new compounds with the greatest potential for registration.

4. A minimum of six greenhouse/ shadehouse studies and phytotoxicity studies conducted on products with the greatest potential for future registration.

5. Registration of at least 3 new products for use in hydrilla control within the timeframe of the project and demonstration of their uses to applicators, agencies, and the public.

Element 2: Evaluation of Currently Registered Herbicides for Control of Hydrilla and Hygrophila

6. Construction of an injector system for drip system applications of endothall.

7. Determination of rates and duration of endothall drip system applications will be established and protocol will be documented and demonstrated.

8. Residue, efficacy, and selectivity data will be collected and published for endothall drip system applications.

9. Determination of rates of endothall and timing of applications for the greatest longevity of hydrilla control in shallow waters. Results will be published and demonstrated to applicators, agencies, and the public.

10. Residue, efficacy, selectivity, and reinfestation source data will collected and published to be used in future studies and to better understand the function of endothall use in shallow water.

11. Development of CET requirements of diquat, endothall, 2,4-D, and triclopyr for use in hygrophila control. The CET and recommendations on the optimal product or product combination for hygrophila control would be published and demonstrated.

Element 3: Biological Control of Hydrilla and Hygrophila

12. Full-scale commercial production of the biological control Mt for hydrilla.

13. Large-scale testing of Mt in Osceola County and demonstrations to applicators, agencies, and the public.

14. Location of a minimum of two possible bio-control agents (insects) in India for the control of hygrophila.

15. Quarantine study of a least one bio-control agent from India.

16. A minimum of four species of hydrilla herbivores will be collected and identified in Africa.

17. A colony of at least one hydrilla natural enemy will be established in Africa.

18. At least one insect will be imported into a quarantine laboratory in Florida for host range and efficacy studies.

Element 4: Demonstrations and Outreach

19. Hire an Extension faculty member to oversee demonstration and outreach of the hydrilla and hygrophila control grant.

20. Conduct four field/demonstration days to show and tell stakeholders about new research and practices to manage hydrilla and hygrophila.

21. Develop an interactive website to include such information as information on biology of hydrilla and hygrophila, invasive species management strategies, new research and new technologies under development, and virtual tours of demonstration sites.

22. Develop a searchable online database on all data, research findings and publications relating to hydrilla and hygrophila management strategies in Osceola County.

23. Develop at least 9 educational displays and/or kiosks.

24. Participate in at least 16 public events with educational displays.

25. Develop interactive science curricula for teachers.

26. Develop a lab kit to accompany science curricula.

27. Conduct teacher training in use of science curricula and lab kit.

28. Develop and maintain a stakeholder advisory committee to represent diverse public interest in hydrilla and hygrophila as well as other potential invasive species.

29. Develop at least 2 additional demonstration/outreach strategies for sharing hydrilla and hygrophila research and management technology.

30. Graduate students and/or researchers will present a minimum of 4 scientific posters at scientific meetings.

31. Graduate students and/or researchers will present a minimum of 4 scientific papers/abstracts for publication.

32. Complete 2 informal, in house usability studies on the interactive website.
