Biological controls as a weed management tool – 6 October 2020

Posted on 17 September, 2020 by Jacqui

Biological control is the practice of managing a weed or pest animal by the deliberate use of one or more natural enemies (biocontrol agents) that suppress it. Land managers, landholders and citizen scientists can each play a role in establishing and monitoring populations of identified biocontrols.  Once established, populations of biocontrol agents can build up to very high levels within a weed infestation. Eventually their numbers can build up to slow the spread or reproduction of a weed, allowing more time for other control methods to be used.

Connecting Country is pleased to support this free online workshop about weed biocontrols hosted by DELWP’s Weeds at the Early Stage of Invasion (WESI) project with Tarrengower Cactus Control Group and the Weed Society of Victoria.

The workshop will feature Dr Raelene Kwong and Greg Lefoe, Senior Research Scientists from Agriculture Victoria’s Research Division. They will explain the ins and outs of what is involved with biological controls as part of your weed management tool kit, and how you can be involved in your patch.

Special local guest presenter, Lee Mead, President of the Tarrangower Cactus Control Group, will provide an exciting local case study. Their community group has used biological controls to combat Wheel Cactus (Opuntia robusta) around Tarrengower and Maldon in Central Victoria.

Biocontrols can play an important role as part of an integrated weed management approach. For tips on getting started with weed control see Connecting Country’s fact sheet – click here
