Improved weed control in coastal NSW grain production

Improved weed control in coastal NSW grain production

The northern NSW coastal grain production region has been identified as an area where increased grain production is a targeted objective. This region is characterised as a high rainfall farming system, typically beef cattle + grain, or sugarcane + grain cropping.

As growers’ transition into increased grain production, any negative experiences due to wrong agronomic decision making is likely to have significant and lasting consequences on further adoption of a grains rich farming system.

Weeds are a major constraint to productivity in this area and failure to employ the latest knowledge and technology can have significant impacts across the entire farming system. Issues such as herbicide resistance and crop injury due to herbicide carryover have been highlighted as issues impacting grain production, while other concerns related to identification of emerging weeds, best practice spray application and drift management are also important to growers.

GRDC has identified the need for enhanced extension in weed management in this region. ICAN will lead a 30 month project to assist local growers in upskilling their weed management knowledge and decision making via a diverse range of extension pathways.

Coastal weeds workshops and seminars

Over the course of the project, ICAN has hosted series of 1-day workshops and extension seminars designed to provide grain growers with the latest information on weed management and control tactics. See below for resources from these workshops.

2022 Coastal Pre-Emergent Herbicide workshops

In 2022 a series of 1-day workshops on pre-emergent emergent herbicides were held. Notes available below

Webinar on coastal weeds

In May 2022, a webinar was run for coastal growers and advisers on coastal weed management. A recording of the webinar is available below.

2021 Coastal Post-Emergent Herbicide workshops

In 2021 a series of 1-day workshops on post emergent herbicides were held. Notes available below

Herbicide resistance testing for grain crops in northern coastal NSW

Results from the herbicide resistance testing will be reported in an upcoming webinar on the 7th of December 2023. Join John Broster and Mark Congreve as they report on the results and implications for management.
