@PBoutsalis For 250 PQ products
Cultivation aid - ~900ml/ha
Fallow optical spray -~3L/ha
Select Pulse crop topping for ryegrass - ~800ml/ha and 14 day whp
Non crop areas ie fence lines -~4L
Closed system drums only
Increased buffers especially aquatic
Tech regos need updated data

@farmersgrowit @Reece_Mason1 @Johnpascoe10 Not necessarily. 240 can suffer the same issues though maybe less common. If a manufacturer has gone for cheaper non-active constituents to save $ in the manufacturing process, you can’t be sure it will be as stable over time unless it’s been assessed, this is not always the case

[Michael Macpherson @MichaelAgSci]

@farmersgrowit @resistance_test @lmkmills1 Formulation is important to Clethodim stability, especially with 360 variants. Consider what brand you are purchasing.
Your supplier should be able to provide DOM if the sticker is illegible.
No ‘expiry date’ requirement for products with demonstrated stability out to 5yrs.

@icelandcricket Bowling your allocated 90 overs a day in a test match 🤦🏻‍♂️

Soil testing the flat today. Let’s see what we have to work with

[Michael Macpherson @MichaelAgSci]

Been a long time coming

Funny really
First job was in a dairy
Now I’m drinking in the historical one I own.

[Michael Macpherson @MichaelAgSci]

@congreve_mark Yes, clethodim is prone to degradation in drum over time, especially in less than ideal storage conditions. Formulation quality is important. 240 seems easier to keep stable via formulation options than 360. One product where non-active components can play a significant role

[Michael Macpherson @MichaelAgSci]

@agrobaz Any notes on storm, heavy rain or irritation, typically in the RESTRAINTS section of the label are usually to do with runoff/environmental assessments. This is a common misunderstanding I hear in the industry. For herbicides, we have included rainfast in the WCWC guide when known

[Michael Macpherson @MichaelAgSci]

@agrobaz Rainfast is not an APVMA requirement for labels in most instances, so many companies won’t take the risk of putting a definitive time on a label.
If there are rainfast guides, they are usually on company tech sheets, and this would be the first place to look.

[Michael Macpherson @MichaelAgSci]

Well it’s taken 20yrs of career chasing, but I can finally say that I have a place of my own. Its not going to be a full time gig, but no doubt it will end up trial central because there’s a heck of a lot of cleaning up to bring it back into peak production 🤣

[Michael Macpherson @MichaelAgSci]

@DMAg_consultant @grassrootsag @WeedSmartAU @HartFieldDay New registration for 4leaf canola can assist in patchy years like this. Edge Unify can go on at 4lf and provide both knockdown suppression and extend the residual window until the crop gets competitive. Can’t use if ppz was used upfront and I wouldn’t recommend cletho mix.

[Michael Macpherson @MichaelAgSci]

Great to see the NSW government are finally adopting no-till practices

The New England hwy probably wasn’t the right place to start though…..

[Michael Macpherson @MichaelAgSci]

@Tedthekelpie @danicaleys No advice from the APVMA in my inbox yet and I will receive notification once any decision lands. Reseller chasing sales possibly

@RedDirt28 Only bad comments on Hilux are the inbuilt sensors in the windscreen. If you replace a windscreen, it has to be done properly and calibrated otherwise it causes issues with cruise control. Otherwise no issues. The Hilux towed my >1t boat better too. Hilux has plenty of go too.

[Michael Macpherson @MichaelAgSci]

@RedDirt28 As someone who has driven both extensively (recent base models) Hilux hands down. Tritons are rattly, tinny and feel cheap with an uncomfortable ride. Head units are buggy for phone connectivity, reverse camera and mirrors have weird opticals that are annoying for reversing.

@AndrewBissett10 @congreve_mark @DMAg_consultant @mattelliott32 @Warwick_Long @TomSummerhayes @mark_jrobbo @mattrohde8 @conlan_matt @SeanM_DMAg_SA @brettbarker92 @CropDoctor54 @leighjbryan @jock_mcneil There are some actives you need to be very careful with in relation to carriage on dust. Group 14s, especially at residual rates such as flumioxazin, Isoxaflutole, Picloram are some known examples causing dust-carriage damage
