Effect of formulation and environment on dicamba volatility

In Webinar 1 from our two-part webinar series ‘Summer spray season challenges’, we hear from Dr Tom Mueller, from the University of Tennessee.

Post application of dicamba on triple stack GM crops has been a success for weed control of glyphosate-resistant weeds in the US, including Palmer amaranth. However, many adjacent areas were affected in 2016 (all illegal use) and 2017 (some illegal, mostly legal applications).

In the below webinar recording, Dr Tom Mueller presents the most recent findings on dicamba behaviour under field conditions and offers some parallels for Australian growers to consider with regard to 2,4-D behaviour and volatility. Check it out below!

 

You can listen to Webinar 2 from the Summer Spraying Series, “Spray wisely and well to maximise efficacy”, with Spray Application Specialist, Bill Gordon, here.

Mixed farming – does it really help control resistant weeds?

In this webinar, WeedSmart Southern extension agronomist Greg Condon looks at the mixed farming system and explains how the Big 6 principles encourage diverse weed management. Greg focuses on solutions in the medium rainfall zone whilst grower and agronomist Craig Drum focuses on the high rainfall zone.
Both Greg and Craig share real-life examples of clients who successfully controlled resistant weeds by using a mixed farming system, whilst remaining profitable.
Topics covered include:

What the WeedSmart Big 6 looks like in a mixed farming system
How to be profitable whilst reducing the seedbank of resistant weeds
Harvest Weed Seed Control opportunities: baled chaff, chafflines
4 examples of clients who successfully controlled their resistant weeds using mixed farming

Considerations for pre-emergent herbicides with dry sowing

In this webinar, we focus on what factors influence the residual control of weeds by pre-emergent herbicides with a focus on Trifluralin, Sakura and new-to-market herbicides.
Join Chris Davey, YPAG and WeedSmart Extension Agronomist and Mark Congreve, ICAN Senior Agronomist as they assess the sowing issues in South Australia and discuss strategies on using pre-emergents.
Factors covered include

Soil type/texture
Rainfall forecast (after application)
Characteristics of the herbicide
Characteristics of the crop
Sowing time (tine vs disc) – sowing depth, speed, soil throw, stubble
Resistance status

Farmer questions answered on Group G herbicides and optimum application temperature

In this follow-up to last year’s webinar on Group Gs, Dr Chris Preston, University of Adelaide, Professor of Weed Management and WeedSmart’s Greg Condon focus on farmer questions around Group G herbicide use.
They explain the new Group G chemistry in simple terms and address questions around what temperature range provides optimum herbicide efficacy.

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.
