Strong interest in exciting new bio-herbicide

Crowd learning of new bio-herbicide for weed control at workshop at Upper Stone, Ingham. 

A new bio-herbicide captured the attention of some 45 landholders from across the region at a recent Field Day at Upper Stone, west of Ingham. Participants walked away armed with inspiration and information to effectively tackle weed control on their properties.

Landholders attending who constantly battle to control invasive weeds, were inspired to learn about the new bio-herbicide which is currently being trialled for Parkinsonia, Prickly Acacia and Chinee Apple. Trials for Lantana will begin soon.

The bio-herbicide is a capsulized mix of fungi which naturally occur within Australian soils. When placed within the stem of the plant, the fungi begins to infect the stem, slowly killing the plant over time before spreading to other plants.

Pathogens contained in Di-Bak are naturally occurring fungi in Australian soils so they have no negative effects on native or endemic plant species.

Victor Galea from University of Queensland said, “The bio-herbicide is in its final stages of development for Parkinsonia, but it is showing promising signs of being an effective, safe and efficient method for controlling several woody weed species”.

Terrain Coordinator Jacqui Richards who attended the workshop said, “The good news is that because these fungi are native to our environment, they don’t have any effects on native plants, animals or humans, it is just using something that’s already here, and we are not introducing something new”.

The workshop included herbicides and application demonstrations including the use of splatter guns. Information was also shared about the identification and control of other weeds such as Navua sedge, Siam weed and more.

The Weed Workshop was organized by the Herbert River Catchment & Landcare Group and funded by the Queensland Government’s Regional NRM Programme with support from University of Queensland, BetterHerbicides Australia, BioHerbicides Australia and Terrain NRM.

Lawrence Di Bella, Chair of the Herbert River Catchment & Landcare Group said, “It was great to see so many landholders attending the workshop and learning about new and innovative technologies which may help landholders better manage their farms.

“These opportunities wouldn’t be possible without the support and funding from Terrain”.
