A visit to a local trial site where pre-emergent control for annual ryegrass (ARG) is the focus will follow the Grains Research and Development Corporation (GRDC) grains research Update at Parkes on July 28. After lunch at the Parkes Services Club, local growers and advisers will travel to the IMAG Consulting replicated trial site between Parkes and Forbes, which has been established under the GRDC’s Southern Region Agribusiness Trial Extension Network initiative.
Glenn Shepherd of IMAG Consulting says there is increasingly heavy reliance on pre-emergent chemistry due to ARG developing herbicide resistance to post-emergent modes of action. “Obtaining the best results from these pre-emergent products requires sound knowledge of how they behave in a variety of field situations,” Mr Shepherd said. IMAG Consulting’s trial is examining the efficacy of pre-emergents in various combinations on ARG control across three stubble treatments – standing stubble, burnt stubble and “tickled” stubble.
“The objective is to provide growers with an independent site highlighting the visual impacts of various treatments, as well as generating replicated, statistically analysed results on product performance,” Mr Shepherd said.
The battle against herbicide resistance in weeds will be up for discussion at the GRDC grains research Update which will be from 9am to 1pm with morning tea and lunch provided. More information on the Parkes Update
is available online or by phoning ORM on 03 5444 4299.
