Increase pre-em efficacy through a mix and rotate strategy

Have you got the best and most cost efficient strategy to nuke your weeds before seeding?

The case is clear: summer weed control is essential!  Controlling weeds through summer and prior to seeding is key to securing moisture and nitrogen for the following crop.

Part 1: Control summer weeds for yield and profit

Every $1 spent on summer weed control can potentially return up to $8/ha through moisture and nitrogen conservation. The impact on grain yield as a result of various summer weed control treatments is what Colin McMaster (NSW DPI R&D) refers to as “buying a spring”.  Listen to Colin and Pete Newman (AHRI) as they investigate the $$ benefits of controlling summer weeds.

Part 2: Increase pre-em efficacy through a mix and rotate strategy

We’ve done a good job of promoting herbicide rotation over the years. And whilst this advice still stands, recent research shows the benefits of mixing herbicides as well.

As American weeds researcher, Pat Tranel, puts it, “rotating buys you time, mixing buys you shots (of herbicide)”. Listen to Pat and Pete as they explore the benefits of the mix and rotate strategy.

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.

What matters more? Crop sequence or seeder?

Why were the batsmen tampering with the ball, shouldn’t that be the bowler’s job? These are all questions that were being asked by a local project committee of growers and advisers, and there was only one way to answer them. Enter Tony Swan from CSIRO. He and his team embarked on a massive, long-term research effort in Temora NSW, working with FarmLink Research to make it happen. The trial ran from 2014 to 2017 and the preliminary results are in. And the winner is… DIVERSITY. (Insert a fist pump from Professor Steve Powles here!) Diverse crop rotations, including a double break, premium herbicides, with some extra crop competition courtesy of barley thrown in, and we have a winner. This diverse crop rotation smashed ryegrass numbers down from 1864 plants/m2 to 145 plants/m2 in just three years, and it was also the most profitable rotation. Article courtesy AHRI.

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.

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.
