    Abstract

    Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed population dynamics and economic returns. Moreover, extended perennial pasture phases are being promoted to address a range of onfarm sustainability issues such as excessive deep drainage (i.e. salinity), runoff and soil erosion. A stochastic bioeconomic model is developed to evaluate potential trade-offs and synergies between the goals of long-term weed management and achieving sustainability goals.
