GRDC Weed Webinars for grain farmers

Effective weed-management strategies are critical to maximising planting opportunities in upcoming seasons and avoiding the costly development of herbicide resistance on farms.

Common sowthistle, aka dandelion, is becoming a major scourge to croppers across Australia - this is the topic of one of the latest in a series of GRDC's Weed Webinars.

With harvest drawing to a close for some and, for others, being held up by wet weather, growers in the northern cropping belt are turning their attention to weed management in a bid to preserve precious soil moisture.

Growers will get the opportunity to hear and discuss the latest weed-management advice at two webinars in late November and early December 2015. The weed webinars are part of an ongoing series of Grains Research and Development Corporation (GRDC) webinars, Advances in Weed Management, that focus on key problem weeds.

The webinars – informative 30-minute presentations from industry experts in their field followed by around 15 minutes for questions from participants – allow growers and agronomists to upskill on the management of particular weeds, and allow time for discussion with experts in the field.

Both Weed Webinars are free of charge; however, you’re required to pre-register to receive the appropriate link to the webinar software. Click on that link at the designated time, and you can listen and join the discussion from the tractor or the office via tablet, laptop or desktop computer.

Webinar 1: Maximising the performance of paraquat-based herbicides in northern fallow

With the continual rise of glyphosate resistance, growers are relying increasingly on fallow weed control strategies incorporating the use of bipyridal (Group L) herbicides. In this webinar, the focus will be on what Group L herbicide strategies are working and how to achieve the maximum performance from these contact herbicides. There will also be time to discuss topical issues such as night versus day application, double knock strategies, tank mixing and the safe use of paraquat.

Presenters will be Independent Consultants Australia Network (ICAN) consultant Mark Congreve; and Shaun Hood, Solutions Development Leader for Syngenta in the northern grains region, who will share his experiences with regard to the development and stewardship of this important herbicide group.

Webinar 1 takes place on Friday 27 November 2015, from 8am Queensland time or 9am NSW/Victoria time. Register for Webinar 1 here.

Webinar 2: The ecology and management of sowthistle

Once thought of as a winter weed, common sowthistle is now causing problems year-round across the northern grains region, particularly in summer fallows. In 2014, the conformation of glyphosate-resistant populations raised the importance of this problem weed significantly.

Webinar Two will draw on the experiences of Michael Widderick and Annie van der Meulen from the Department of Agriculture and Fisheries Queensland (DAF), who have led the weeds research team studying the ecology, evolution of resistance and management of sowthistle in the northern grains region. They will discuss the ecology of this pernicious weed, give an update on herbicide resistance, and discuss how we can use this information to develop effective sowthistle-management strategies.

Webinar 2 will take place on Friday 4 December 2015 from 8am Queensland or 9am NSW/Victoria time. Register for Webinar 2 here.
