GRDC Code: UOA1505-001RTX
UA00156 - Emerging weeds (Seed-bank biology of emerging weeds)
Changes in farming systems, weed management practices and climate have contributed to the change in weed flora on Australian farms. Much of the Australian research on weed seed biology was undertaken prior to the intensification of cropping and before the introduction of no-till systems. It is likely that the biology of many weed species has changed in response to changes in crop management practices. In response to this, the current project aims to quantify the behaviour of seedbanks of emerging weed species in terms of variation in seed dormancy, seed persistence, pre-harvest dispersal, reproductive output and competitive effects on crops.

Caltrop (Tribulus terrestris) is a significant and persistent summer weed in most grain growing regions of Australia. Strong vines, sharp, woody seeds and a very short growth cycle make caltrop problematic for a range of reasons.

The key message from this issue of Paddock Practices is for all regions is to act early and stay on top of emerging weeds during summer and autumn for optimum soil moisture and nutrient conservation and to minimise the ‘green bridge’ for
