Herbicide resistance has become a major problem in Australian dryland agriculture. This situation has resulted from the repeated use of herbicides in place of the traditional weed control provided by cultivation and grazing. Farmers have addressed the problem of herbicide resistance by adopting...

A multi-species version of the bio-economic RIM (Resistance and Integrated Management) model has been developed to deal with the complexities involved in the long-term integrated management of annual ryegrass (Lolium rigidum Gaud.) and wild radish (Raphanus raphanistrum L.), which dominate and...

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...

Perceptions are known to play an important role in the innovation adoption decision. Once influential perceptions have been identified, there is the potential for information to influence adoption by changing these perceptions. In this paper, the influence of an extension workshop targeting...

Social costs and externalities associated with herbicide resistance have not generally been considered by economists. The economics of managing herbicide resistance in weeds has focused on cost-effective responses by growers to the development of resistance at the individual farm and field...

In face of climate change and other environmental challenges, inclusion of perennial forage shrubs in Australian agricultural systems has the potential to deliver multiple benefits: increased whole-farm profitability and improved natural resource management. The profitability of shrubs was...

Mallee farmers minimize downside risk in dry seasons by applying low rates of nitrogen (N) fertiliser to their cereal crops. The opportunity to respond to and capitalize on the better years is further limited as most inputs are applied upfront at sowing. We used an economic-risk decision model...

Simulation models are valuable tools in the analysis of complex, highly constrained economic systems unsuitable for solution by mathematical programming. However, model size may hamper the efforts of practitioners to efficiently identify the most valuable configurations. This paper investigates...
