Herbicide RegistrationProcess for aquatic registration
~ 140 health and environmental tests
~ 8-10 years for full EPA registration
~ $40-60 million for aquatic registration
![Page 15: Florida’s Aquatic Plant Management Program …Citra, FL March 3, 2015 Jeff Schardt FL Fish and Wildlife Conservation Commission Invasive Plant Management](https://reader035.vdocuments.net/reader035/viewer/2022081605/5a4d1ada7f8b9ab0599748ce/html5/thumbnails/15.jpg)
Herbicide Registration• USEPA registers for aquatic use• FDACS registers for FL use
– envt. agencies comment to FDACS– new compounds - uses / sites
• FWC permits / contracts use in water– funds research
• rates, selectivity, timing, synergy
![Page 16: Florida’s Aquatic Plant Management Program …Citra, FL March 3, 2015 Jeff Schardt FL Fish and Wildlife Conservation Commission Invasive Plant Management](https://reader035.vdocuments.net/reader035/viewer/2022081605/5a4d1ada7f8b9ab0599748ce/html5/thumbnails/16.jpg)
Research Management• Reproductive methods
– seed / propagule viability• Weakness in life cycle• Susceptibility to available controls
– synergistic effects• Impacts to non-target organisms

Minimize Herbicide Use
• Integrate with other methods• Apply lowest effective rates• Apply when target is most susceptible• Control before problems develop

Management Decisions
• Uses / functions • Plant species present • Impairment• Technology• Current conditions• Budget
![Page 21: Florida’s Aquatic Plant Management Program …Citra, FL March 3, 2015 Jeff Schardt FL Fish and Wildlife Conservation Commission Invasive Plant Management](https://reader035.vdocuments.net/reader035/viewer/2022081605/5a4d1ada7f8b9ab0599748ce/html5/thumbnails/21.jpg)
Management Dilemma
• Manager perspective – control invasive plants before they
become a problem
• Stakeholder perspective – don’t control plants until they become a problem
