The biology of Australian weeds: Volume 3
No full textOver the past decade, The biology of Australian weeds series has presented summary chapters about the biology, taxonomy, significance and control of most of Australia's most problematic weeds. Many of these chapters first appear in Plant Protection Quarterly and are then updated and revised for the book. Dane Panetta was also an editor of the second volume. This volume contains chapters of a further sixteen weed species including several of interest to Queensland
Predicting weediness - what has the CRC achieved?
No full textDane Panetta and colleagues recently published their paper 'Predicting weediness - what has the CRC achieved?' in Proceedings of the 16th Australian Weeds Conference. They reviewed the research outcomes from the CRC for Australian Weeds Management for predicting weediness of plant species and concluded that advances have been made in identifying traits that distinguish high impact species for a range of environments. However these were not consistent between studies. They considered that Australia's border Weed Risk Assessment System has performed well under considerable local and international scientific scrutiny though minor improvements could still be made
Skeleton weed : how serious a threat in Western Australia?
No full textSkeleton weed is probably the most serious weed ever to threaten the Australian wheat industry. It interferes with wheat cropping at two stages: through competition with the growing crop, particularly for nitrogen and water during the crop\u27s development: and later through the production of a tall, wiry flowering stem which tangles in harvesting machinery and can make harvesting difficult, if not impossible.
The weed is a major problem in eastern Australia although a combination of cultural, chemical and biological control programmes is helping to reduce its impact.
In Western Australia, skeleton weed is being contained mainly by eradication efforts. Weed Agronomy Research Officers, F.D. Panetta and J. Dodd, are studying the ecology of skeleton weed to determine why it hasn\u27t spread further and how current control methods can be more effectively applied

Optimising weed control by considering disturbance
No full textMounting scientific evidence suggests newly imposed disturbance and/or alterations to existing disturbances facilitate invasion. Several empirical studies have explored the role of disturbance in invasion, but little work has been done to fit current understanding into a format useful for practical control efforts. We are working towards addressing this shortcoming by developing a metapopulation model couched in a decision theory framework. This approach has allowed us to investigate how incorporating the negative effects of disturbance on native vegetation into decision-making can change optimal control measures. In this paper, we present some preliminary results
