Integrated Management of Hydrilla

Florida CISMA Webinar 22 October 2014

Outline

• Introducing hydrilla (distribution, problems)

• Options for hydrilla control

• Why is IPM important?

• Current status of research

• Outlook


• Submersed, rooted; propagates by tubers, turions, fragments!

• Stems – long and slender with some branching

• Leaves – max. 4/5’’ long, 1/6’’ wide, lanceolate, whorls of 3-8

• Midrib – bears small spines

Introducing Hydrilla

• Interferes with boating

• Drainage canals / flood control structures

• Fast vegetative growth dense vegetation mats

• No natural enemies, outcompetes native vegetation invasive

• Resistance to certain herbicides

• Control very costly

• Eradication impossible innovative maintenance control

Why Is Hydrilla Such a Problem?

What are the Options for Hydrilla Management?

• Physical control (drawdowns, barriers)


• Mechanical removal (harvesting)

• Chemical control (herbicides)

• Biological control (herbivores, pathogens) will give more details

Promising Biological Control Agents

Sterilized Asian grass carp – successful in closed systems (1972 first release in FL)

Cricotopus lebetis, the hydrilla tip miner – 1976 first record in SW FL; 1992 in Crystal River

Parapoynx diminutalis, the hydrilla leafcutter moth – 1976 first record in FL

Mycoleptodiscus terrestris , the Mt fungus – 1970s isolated from several U.S. locations

Hydrilla Tip Miner Larva and Associated Tip Damage

• Causes profuse branching

• Prevents hydrilla from “topping out”

• Does not disperse far (would need to be moved to new areas)

• Can be mass reared

• Does not kill the plant but kills the growing tips

Lake Rowell, Bradford Co., FL September 2010


Combining (Integrating) Methods — Why?

Benefits of Integrated Pest Management (IPM)

• Increased efficacy

• Decreased use rates

• Reduced contact time requirements

• Improved selectivity

• Reduced reliance on herbicides alone

• Resistance management

Combining Control Agents/Tactics to Manage Hydrilla

Compatibility Tests:

• Mt fungus

• Tip miner

• Chemical herbicides

• 2014: Mechanical (Harvesting)


Tank Test Methods

• Comparison:

– No treatment

– One agent

– Combination of two agents

HYDRILLA: HOW WE ARE CHANGING THE ARCHITECTURE

What Can You Do?

• Give our info materials to your friends

• Never dump the contents of your aquarium

• Note your observations on the lake

• Report any suspected infestation

• Clean your boating and fishing equipment
