Location Specific Management Information
Physical and chemical control tend to be very difficult. Biological control agents are being investigated (Csurhes and Edwards, 1998).
Asparagus species are generally best controlled using the “crowning” technique where the above ground part of the plant is cut from the root system and hung up off the ground. Tubers can be painted with glyphosate. Runners near the ground can be gathered up and their main root systems removed. Regrowth needs to be controlled whilst it is actively growing (preferably between flowering and fruiting) with such techniques as foliar spraying with glyphosate (1 part glyphosate to 75 parts water) or metsulfuron methyl (1-2g in 10L of water) (Regional Weeds Advisory Committee, 2004).
Lord Howe Is.
Asparagus densiflorus has been declared a noxious weed on Lord Howe Island (Csurhes and Edwards, 1998).
Waikato Region (North Island)
Asparagus densiflorus is classified as a “Potential Plant Pest” by Environment Waikato, which means it is recognised as a potentially invasive weed in the Waikato Region.
Please see definitions for hierarchy of pest designations.

3. CRC for Australian Weed Management 2004. Introductory weed management manual. Australian Government. Department of Environment and Heritage.
Summary: This manual has been prepared as a training aid for the use of private landholders, conservation groups, catchment management groups, local, state and territory governments and industry. It is an introductory guide for those with little experience with weed management, particularly environmental weeds. It will be of use to those who wish to develop their weed management knowledge and skills, and as an extension resource for those who need to develop the weed management capacity of others. The manual is presented in four modules:
- Module 1: Developing and implementing a weed management plan
- Module 2: Weed control methods for community groups
- Module 3: Collecting and preparing plant specimens for identification
- Module 4: Presentation of information sessions to small groups

Summary: This compilation of information sources can be sorted on keywords for example: Baits & Lures, Non Target Species, Eradication, Monitoring, Risk Assessment, Weeds, Herbicides etc. This compilation is at present in Excel format, this will be web-enabled as a searchable database shortly. This version of the database has been developed by the IUCN SSC ISSG as part of an Overseas Territories Environmental Programme funded project XOT603 in partnership with the Cayman Islands Government - Department of Environment. The compilation is a work under progress, the ISSG will manage, maintain and enhance the database with current and newly published information, reports, journal articles etc.
