Biological control in the form of Nigrospora crown rot is now a viable option for WSGs, particularly giant Parramatta grass. As producers are becoming aware of Nigrospora crown rot they are integrating the biocontrol with their existing weed management strategies.
Fungal control of Giant Parramatta Grass – chemical-free
Oct 18, 2018 · Beechwood NSW farmers Cathy Eggert and Jeremy Bradley have established a chemical-free solution to Giant Parramatta Grass. “A widespread native soil fungus, Nigrospora oryzae, causes crown rot disease in these species and has been spread by transplanting diseased plants without off-target impacts for nearly 20 years. An innovative farm-based ...
Bio-scientist, Jeremy Bradley, has found a way to add the Nigrospora oryzae spores to a mulch, called Parra Trooper. It is not a herbicide, but it helps to cause crown rot in Giant Parramatta grass (Sporobolus fertilis), and has been shown to aid in the reduction of vigour and persistence in Giant rat's tail grass (Sporobolus pyramidalis) too.

Parramatta grass (Sporobolus africanus), which is usually shorter (<1 m tall) and has smaller seed heads (up to 18 cm). Giant rat’s tail grass ( Sporobolus pyramidalis) which is very similar but as the seed head matures its branches move apart to form a pyramid.
Utilising Crown Rot Fungus for biological control of Sporobolous ...
This project investigated the ability of the fungus Nigrospora oryza to cause die back in GRT and subsequent potential as a biocontrol agent of GRT. This fungus has been proposed as a pathogen of Giant Parramatta Grass (GPG) (S. fertilis), a closely related species to GRT.

The base of dying or dead Parramatta Grass tussocks are now being overgrown with grasses and legumes, demonstrating that the fluproponate has only affected the Parramatta Grass. The manufacturer recommends a second application two years later to ensure near total eradication.

May 18, 2015 · The Bundaberg Regional Council has teamed up with the New South Wales Department of Primary Industries, to test if a fungus known as crown rot can be used to slow the advance of giant rat's tail, and cut costs for landholders trying to control it.
