Innovative science in Australia’s southeast will help farmers set a new land weed record for no-till and mixed farming systems.
Researchers at Charles Sturt University, collaborating with colleagues at The University of Adelaide and the Grains Research and Development Corporation, have found new ways to combat weeds that have become resistant to herbicides.
Charles Sturt Research Professor of Plant Biology Leslie Weston led the team which worked in a variety of agricultural zones.
Professor Weston said the long-term project had captured extensive information about the extent of herbicide-resistant weeds across southern Australia’s mixed farming zones and proved the effectiveness of a range of strategies.
“The key findings from our research were that rotations with diverse and competitive crop types, along with early crop vigour and high total crop biomass in canola, barley and wheat varieties, correlated strongly with effective weed suppression,” Professor Weston said.
The research also made new findings on the distribution and biology of weed species.
“As a result of this research we have been able to identify why specific weeds such as barley grass are a problem in continuous cropping and mixed farming systems and determine their impact on crop, pasture and livestock production,” she said.
