New uses for existing chemistry
Herbicide resistance is a major problem in Australian grain cropping, reducing the herbicide choices available to growers and increasing their costs. There is a need to increase the availability and flexibility of controls for herbicide-resistant weeds, including new herbicide uses.
This project will develop data sets for registration of new uses for existing herbicides. The main output will be the development of new herbicide treatments for the site-specific management of feathertop Rhodes grass, awnless barnyard grass, fleabane, sowthistle, brome grass, barley grass, and wild radish present in crop and fallow situations. The focus in the GRDC southern region will be to find alternative options for controlling winter grass weeds. The focus for the GRDC northern region will be to find alternative products or combinations of products for optical spray technology application or developing new treatments for more recently discovered glyphosate-resistant species. In the GRDC western region, work will finalise new treatments to combat wild radish.
