Troublesome weed under the microscope at Yerong Creek
A problematic weed which has recently made its way into southern New South Wales cropping systems will be under the microscope at a grains research forum in Yerong Creek in March.
The arrival of the weed fleabane has created a new and serious agronomic issue for regional grain growers, prompting authorities to prioritise it for discussion at the Grains Research and Development Corporation (GRDC) grains research Update on March 14.
The GRDC and Update organisers have worked closely with local farming systems group FarmLink Research to assemble a number of experts to address fleabane’s emergence in southern NSW, according to GRDC Southern Regional Panel chair David Shannon.
“DPI NSW’s Col McMaster and Han Wen Wu will be joined by Neil Durning of AgnVet and Col Plater from Dow Agrosciences in offering growers insights into fleabane and the options available for control in fallow and pasture,” Mr Shannon said.
“Fleabane is recognised as one of the most difficult-to-control weeds in southern Queensland and northern NSW, where recent consecutive wet summers stimulated significant seed production, leading to the weed’s spread south.
“Some populations of fleabane in the northern cropping region have been found to be resistant to glyphosate, which is a major cause for concern.”
Mr Shannon said herbicide resistance was another hot topic to be addressed at the Yerong Creek Update where Western Australian farmer Rod Messina will speak about his experiences in overcoming the resistance challenge.
“James Hunt from the CSIRO will discuss managing water use efficiency, while the trials and tribulations associated with row spacing will be relayed by Greg Condon of Grassroots Agronomy, Peter Martin from NSW DPI, and Adam Inchbold from Riverine Plains Inc.
“Robert Patterson from Rural Management Strategies at Cootamundra will present his thoughts on the viability of intensive farming systems, Sally Martin from NSW DPI will delve into the economics of sheep production, and FarmLink’s Paul Breust will update local growers on trials being undertaken by the group.”
Mr Shannon said the program for the Update at the Yerong Creek Bowling Club had been specifically designed for local grain growers who will be provided with expert advice and support to prepare them for the 2012 cropping season and beyond.
A detailed program for the Update (to run from 9am to 4pm with morning tea and lunch provided) can be obtained by visiting www.grdc.com.au/updatedates or by contacting ORM on 03 5441 6176 or email firstname.lastname@example.org.
