Pasture Dieback

Pasture dieback is a condition that causes unthrifty growth and premature death of otherwise productive tropical and sub-tropical sown-grass pastures. Some native grass species are also affected. Broadleaf plants (eg weeds, legumes) are not affected.

Pastures in eastern Queensland are affected, specifically north and central Queensland, Wide Bay-Burnett and south-east Queensland. The condition was diagnosed in tropical grass-pastures was confirmed in north-east New South Wales early 2020.

Initially, pastures are affected in patches and exhibit leaf yellowing, reddening, or both, poor growth and senescence, and premature death. For reliable diagnosis other potential causes of the observed symptoms need to be ruled out and pastures need to progress through the full cycle of symptoms through to death.

The condition causes losses in pasture production, which reduces carrying capacity and beef production per hectare. Pasture dieback has been observed across a range of soil types, landscape locations (ridges, gullies, slopes, flats) and grass species. Stock avoid grazing affected areas.

Currently, no confirmed causal agent(s) have been identified.
