How to make the right decision on using Group Gs in the Northern cropping system

Group Gs have a place in northern cropping systems both in summer and winter crop scenarios. We ask Andrew Somervaille to explain Group G use in both systems and the most optimum use of different Group G products given the range of seasonal conditions in the northern cropping region.

How do I make the right decision on using Group Gs?

Choosing and applying the right pre-emergent herbicide can be difficult, particularly if herbicide resistance is becoming a challenge in a no-till system. Join Dr Chris Preston, University of Adelaide (UA) professor weed management and WeedSmart’s Chris Davey as they explain the new Group G chemistry and de-mystifies which Group G works best for winter cropping systems.

Double breaks – a double shot at annual ryegrass

Perhaps you’re a ‘short black’ wheat-canola type, strong on inputs? Or a ‘long black’ type who likes to dilute their rotations a bit more? Or are you a ‘double shot’, throwing in a few break crops in a row for maximum effect? When it comes to managing annual ryegrass populations, Tony Swan and the research team from CSIRO Plant Industry and FarmLink, have shown that ‘double shots’ are the key. Growing two break crops in sequence (broadleaf crop, hay crop or long fallow) was more effective in reducing resistant ryegrass numbers to manageable levels than a single break crop or continuous wheat over a three-year rotation. And it can still be profitable.

RIM: Ryegrass Integrated Management

RIM is a hands on, user-friendly decision support software that allows farmers and advisors to evaluate the long-term cropping profitability of strategic and tactical ryegrass control methods, on the long-term and at the paddock scale. RIM lets you test your ideas: How can you run your ryegrass down and profit up? New rotation? New technique? View the full video here

Handling weeds in a strip and disc system

Hear from Dr Michael Walsh, Sydney University and Greg Condon, WeedSmart on dealing with weed challenges in strip and disc systems. Growers are using a wide range of cultural tools with herbicides to successfully farm in high residue cropping programs.

Testing all of your herbicides for resistance with Roberto Busi

  Dr Roberto Busi Roberto discusses what the current levels of resistance to knock-down herbicides (glyphosate and paraquat) are, resistance to new and old pre-emergent herbicides and resistance to clethodim. The results are discussed with Peter Newman by analysing the pros and cons of herbicide resistance testing and the value of herbicide efficacy and resistance testing with new herbicides coming into the Australian market from 2021.

Glyphosate Resistance Update with Peter Boutsalis

Dr Peter Boutsalis from the University of Adelaide joins this webinar to discuss tips to optimise the efficacy of glyphosate and when and when not to use the double knock strategy. Peter also shares the latest results from the GRDC-funded random weeds survey in the Eyre Peninsula and southern Victoria and how the resistance levels in these areas have changed over the last 5 years.

You don’t know what you don’t know about managing weeds

Agronomists play a key role in the northern region, not only in identifying and tackling crop weeds but also in protecting chemistries. In the face of this challenge, utilising the WeedSmart Big 6 tools is showing results in tackling problem weeds. Join Crop Consultants Australia’s Director Ben Dawson, as he hosts Dr. Chris Preston and Paul McIntosh from WeedSmart and they discuss the role that agronomists can play in breaking this cycle.

New chemistry – what’s new, what’s coming & how to keep them for longer

There is a range of new pre and post-emergent herbicides coming to the market in the coming seasons which will broaden weed control options and use patterns. As new chemistry becomes available it is crucial for all involved to protect the longevity of any new products and minimise the risk of resistance. In this webinar, WeedSmart’s Southern Extension Agronomist Greg Condon will explore the opportunities these new herbicides provide growers and how we can protect these herbicides using the WeedSmart Big 6.

Know thy enemy – biology of our most problematic crop weeds with Dr Catherine Borger

These weeds cost growers $22.5 and $1.7 million per year, respectively. Understanding the ecology of these species is vital to developing a successful weed management plan. A five-year GRDC project produced results on emergence patterns, seed bank persistence, seed shedding and competitive ability of great brome and barley grass, in Western Australia and South Australia (‘Seed bank ecology of emerging weeds’ UA00156). The project found that three to four years seed set control was needed to remove a great brome or barley grass soil seed bank. Great brome had high seed production in Western Australia and South Australia. Barley grass had much higher seed production in South Australia than Western Australia. Great brome grass and barley grass reduced crop yield, and in 2019, great brome at low to high densities reduced economic returns from a Mace wheat crop at Wongan Hills by $90-205/ha. Barley grass reduced economic returns of wheat by $67-138/ha. Data on weed ecology and competitive ability was used to update a decision support tool; the Weed Seed Wizard (WSW). The updated model was used to investigate harvest weed seed control (HWSC) as a potential management technique for great brome grass and barley grass. The modelling indicated that harvest weed seed control is a valuable tool in the management of these species, even in the years where most weed seed is shed prior to harvest.

WeedSmart in HRZ – practical options for dealing with ryegrass

Effective ryegrass control is becoming increasingly difficult in High Rainfall Zone farming systems. This webinar is designed to help growers and agronomists explore farming system- based options to manage annual ryegrass populations in our cropping areas. Grassroots Agronomy’s Greg Condon is a leading agronomist from Southern NSW, involved with the GRDC’s National WeedSmart project, which focuses on ‘the farmer calling the shots, not the weeds’. Greg will present options, (not just chemical) which HRZ growers could integrate into their farming systems to help manage difficult-to-control weeds. This webinar is brought to you by Southern Farming Systems and the Grains Research Development Corporation and presented by WeedSmart.
