Harrington Seed Destructor: A New Nonchemical Weed Control Tool for Global Grain Crops: Crop Science 2012. Walsh, Harrington & Powles. 

In AHRI we are very proud of this paper and we have high hopes that the Harrington Seed Destructor (HSD) will become adopted by a significant percentage of Australian grain growers. We believe that harvest weed seed control (HWSC) is a very important part of integrated weed control strategies. HWSC can be achieved with narrow windrows/burning or with chaff carts. In this Crop Science paper our research reveals that the HSD is equally effective to these techniques and with several advantages. This paper is the culmination of many years of work and congratulations to Michael Walsh for the work that he has led in this project. Our thanks to outstanding farmer and agricultural inventor extra-ordinarire, Ray Harrington.

Resistance to either paraquat or ALS inhibiting herbicides in two Western Australian Hordeum leporinum (barley grass) biotypes: Pest Management Science 2012. Owen, Goggin & Powles.

This study documents paraquat resistance in a Hordeum leporinum WA population. Despite paraquat resistance in Hordeum in several Australian states, paraquat resistance remains a minor problem in Australia, largely due to the reality that paraquat is not widely and persistently used. Glyphosate is mostly the non-selective herbicide of choice. Thus, understandably, paraquat continues to be effective because it is not widely and persistently used. What is interesting about these ALS herbicide resistant Hordeum leporinum populations is that they evolved resistance from selection with older ALS herbicides (chlorsulfuron, triasulfuron, metsulfuron) registered against other weed species but not registered for Hordeum control. These older herbicides had some activity on Hordeum and hence selection for resistance occurred.
