  • War on weeds to headline GRDC updates

    University of Sydney weeds research director Michael Walsh will be one of a number of speakers at GRDC Grain Updates in NSW later this month.

Southern NSW grain growers will remember 2016 as a really wet year that for many resulted in massive weed seed blowouts.

Advice for growers on how to deal with the increased weed seed bank will be one of the headline acts at the Grains Research and Development Corporation’s Grains Research Updates later this month.

Presented by the University of Sydney weeds research director Michael Walsh and Greg Condon from Grassroots Agronomy, the focus will be on providing growers with effective strategies to combat increased weed pressure.

‘‘Constant rainfall through winter reduced the effectiveness of pre- and post-emergent herbicides, when growers could actually get onto paddocks and the effect of waterlogging reduced crop competition, which was a combination that allowed weeds to proliferate even in previously clean paddocks,’’ Dr Walsh said.

‘‘But our message to growers is there are numerous options to tackle their weed issues now, they just need to get aggressive and adopt some of the more alternative, but proven, weed control options.

‘‘Start with the double knock, then use crop competition, top it all off with harvest weed seed control tactics and then be prepared to do it all again next season.’’

GRDC grower services manager north Sharon O’Keeffe said the annual updates across NSW focused on bringing industry the latest research and development from short and medium-term projects that addressed growers’ priority issues — from farming systems, agronomy, soils and weeds to pests and diseases.

‘‘The updates play a vital role keeping growers and advisers informed of the latest tools, advice, information and innovation to improve on-farm productivity and profitability,’’ Ms O’Keeffe said.

Strategies to manage weed seed blowouts in 2017, along with the latest regional results from Harrington seed destructor trials, are just some of the many grower-focused topics on the agenda at the upcoming GRDC updates.

Impacts of a wet season on crop nutrition, the verdict on strategic tillage, effective and practical use of precision technology, along with the latest research into pests and diseases, will also be on offer.

Other update topics on the agenda, which are designed to help growers improve productivity and profitability, include:

The latest on managing the Russian wheat aphid.

The role of a hay enterprise in the rotation: Agronomics and economics.

Better pastures, better crops: Management of pastures in a mixed farming system.

Local research into improving wheat yields in hostile soils.

What are the key drivers for high-end irrigation yields?

An integrated approach to advanced canola management.
