Herbicide resistance has become a major problem in dryland agriculture. In Australia this particularly applies to annual ryegrass (Lolium rigidum) which has developed multiple resistance to a wide range of commonly used selective herbicides. Although herbicides are a very cost-effective means of...

Uncertainty has been under-recognised as an impediment to the adoption of innovative land conservation practices. High levels of uncertainty inhibit adoption because (a) most farmers are psychologically averse to risk and uncertainty, (b) uncertainty leaves room for misunderstanding and...

Cropping on yellow earth soils in the eastern wheatbelt of Western Australia can be restricted by subsoil acidity. There are approximately one million hectares of yellow earth soils in Western Australia, some of which are extremely unproductive due to acidity and high concentrations of available...

The Fitzgerald River National Park is one of the world’s 25 biological hotspots, containing many endemic flora and fauna species. Its unique biodiversity is being threatened by the introduced root pathogen, Phytophthora cinnamomi. We evaluate the cost-effectiveness of strategies to manage...

This paper describes a dynamic simulation model that has been developed to provide a comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model...
