Project Description

Over the last two decades northern region crop production has changed dramatically from systems dominated by cultivation and residue removal to those with little or no soil disturbance and complete residue retention.  These dramatic changes in production practices will likely have also impacted on the biology of weed species infesting these production systems. For example, it is now evident that the effectiveness of harvest weed seed control is improved through crop competition increasing the height of retained seed. Additionally as we move towards the development of site specific weed control technologies the efficacy of these systems will rely on a thorough understanding of the biology of the weeds being targeted. 

The general approach for this area of research is to investigate key biological attributes (dormancy, seedbank viability, seed dispersal, phenological development etc.) of northern region problematic weed as they occur in crop and fallow situations with the aim of identifying control opportunities.  

The successful applicant will enrol through the Queensland Alliance for Agriculture & Food Innovation (QAAFI).
