What TCCG has Done since 2005
Trialing Methods of Killing Wheel Cactus Plants
Late 1990’s-Early 2000’s: Barry McKnight – Injection gun and screwdriver
Barry McKnight, a landholder in The Nuggetty area, tried an injection technique already being used in areas of South Australia on Wheel Cactus infestations. He gave a demonstration of this injection method using a gun and screwdriver, to other interested local farmers and Landcare enthusiasts.
2000-2004: Ian Grenda
Ian Grenda, also a landholder in The Nuggetty area, trialled several new ways to kill Wheel Cactus because the gun and screwdriver technique was slow and tedious. He tried shooting holes in the lobes, shattering the lobes with a shovel and releasing the insect Cactoblastus as a biological control agent. However, none were successful.
2004: Bendigo Regional Institute of TAFE Diploma in Conservation and Land Management
Jenny Baig and Brett Tyler, students in the Diploma of Conservation and Land Management, performed a trial to test the efficacy of surface spray of the herbicide glyphosate onto Wheel Cactus plants. They concluded that spraying with 2% glyphosate and 0.2% Pulse (a wetting agent) had an effect on the development of the plant but regrowth did occur and the plants did not die.

2005 and 2006: Ian Grenda – Spraying with Glyphosate
Ian Grenda had some success spraying Wheel Cactus with a mix of 2% glyphosate and 2% Pulse in overcast weather conditions, but still there was regrowth of the plants requiring further follow up control treatments. Ian found that the most effective and permanent killing of the plants resulted from direct injection of the herbicide glyphosate into all outer lobes using an Injection Kit comprising of a drenching gun and extra long spear.
Education and Public Awareness
TCCG publish regular articles in local newspapers to educate and reinforce to the community the enormity of the Wheel Cactus problem in their local landscapes. Articles and photos are published in Landcare and environmental magazines about the groups activities and interviews are also conducted on local radio programs.
Brochures and Mail Outs
Various information brochures have been produced and printed to distribute within the community, to advise best-practice techniques and to promote TCCG’s demonstrations and field days. These are distributed via local public venues and businesses, at local community events and also posted to property owners within the local Shire areas that are most affected by Wheel Cactus infestations.
Workshop and Field Trip
In May 2015, the TCCG committee planned and held a half day workshop in the Baringhup hall and a field trip to a nearby property, to help increase awareness of the threat of Wheel Cactus infestations to neighbouring Shires and other land managers, highlighting the problems associated with Wheel Cactus infestations to native flora and fauna in public lands, the impact on domestic livestock and crops and the negative economic impact on private properties. Refer to Workshop Invitation.
Demonstrations and Advice for Landholders
Volunteers of TCCG have provided advice and demonstrations to property owners in their own time outside of the regular community field days.
Equipment Loans as Incentives
Injector backpacks and probes, digging tools and buckets are all available for loan by land holders to encourage them to control the Wheel Cactus infestations on their own properties.
Over many years, TCCG have investigated the best techniques to kill Wheel Cactus plants permanently, and developed an efficient injecting tool to deliver herbicide directly into the lobes. They have also sourced the most effective digging hoe for manually removing smaller plants.
TCCG volunteers participate in regular local, community events such as the annual Maldon Easter Parade and Maldon and Baringhup Agricultural Show, to help raise awareness about the threat of Wheel Cactus and the groups existence.
Members of TCCG designed and raised funds to acquire a trailer built specifically to store and transfer all the injecting and digging equipment required at their community field days, plus the very important BBQ and gas bottle.
T-Shirts, Coffee Mugs, Bumper Stickers and Pens
To help raise awareness of our “Wheel Cactus War” the group has designed and printed t-shirts with a striking image, hand painted coffee mugs with an appropriately sad looking Wheel Cactus plant, and a logo was designed and used to print bumpers stickers and pens, all to distribute to our volunteers and within the local community.
Networking with Similar Groups
Committee members have attended demonstration days, meetings, forums and conferences held by similar groups to exchange information and share knowledge, concerns and achievements. These groups include the Wychitella Landcare group in north central Victoria and the Blinman-Parachilna group in central South Australia. Contact is also maintained with the National Invasive Cacti Network, Connecting Country and government departments such as Parks Victoria, the North Central Catchment Management Authority and the Department of Primary Industry and Regions South Australia (PIRSA).
TCCG committee members also attend and present papers at conferences held by groups such as the Victorian and Australasian Weed Societies and Australian Landcare.
Farm Fence Signs
As part of the TCCG Victorian state-wide Mapping Project, members designed a sign to distribute to local landowners to hang on their fence in a prominent location, to help remind the local community to destroy Wheel Cactus plants.
Hosting Volunteer Groups from other Regions
Since 2010, TCCG has hosted several field trips each year for several different organisations, and have greatly appreciated the valued help from these different community groups: Ballarat Special School, Lalor High School, Roxburgh Park College, Monash University Biological Society, LaTrobe University Bendigo, TAFE Bendigo, Mobile Landcare Group, IBM corporate volunteers, Castlemaine Venturer Scouts.
Funding and Support
Members of our committee identify and apply for suitable grants from local, state and federal sources. A list of and links to our major sponsors can be found below. We also alert local property owners to funding grants so they can seek support for their individual eradication programs.
Community Field Days
TCCG area of focus is bounded by Cairn Curran Reservoir (Baringhup) on the west, Trudgeons Road (Welshmans Reef) on the south, Maldon-Lockwood Road (Nuggetty) and Maldon-Newstead Road on the east and Bradford Road (Shelbourne) on the north. We hold community field days on each of the cooler months where we demonstrate killing techniques to property owners and also welcome any volunteers willing to learn to kill and help eradicate Wheel Cactus from our environment.
