@JarrodAmery I believe Impact still make it in Australia

Australian manufactured Super Phosphate from Geelong comes to an end of era. Seems a shame.

@robbert115 Great work there Roberto, any difference with 1% AMS? Also have your tried the addition of terrador/Voraxor? Could it be a one pass option for gly resistant ryegrass? /Rotation option?

2L (generic) glufosinate - on the left ——————vs——————- 2L (generic) glufosinate + 2% AMS granules - (2kg in 100L of water) on the right Ryegrass and wild radish as target weeds - 10DAT. This is not new but still spectacular to see: it’s chalk snd cheese!

Great turnout today at the Greenthorpe farming systems sites, an excellent 7 year project still running, well done to all involved with the massive effort from these sites including the actual grazing plots using real 4 legged animals to simulate paddock practices.

@agriprof How do you mean?

I’ve seen more than enough to see Charlie Kirk was not shot. But a Turning Point in the movie/war? Possibly.

@brill_ag @theGRDC Wow that’s a huge response with those soil levels! Why so responsive do you think? Is it a high PBI?

Nil P v 25 kg/ha P applied at sowing. 12 kg P broadcast on both in February (single super). Colwell P = 61 mg/kg, pH = 5.4 in 0-10 cm. Ganmain Pulse Agronomy site @theGRDC

@agrobaz I feel you Baz, has to clarify again with rep yesterday on one, said don’t apply within 3 days of heavy rainfall and nothing else, I was left scratching my head but got somewhat of an answer. I’d like to have a dollar for every time I’ve read that!

It would be really nice if all fungicides had a clear rainfast period on their labels! It would certainly save agronomists a lot of phone calls. Extra points for a formal answer of Epoxiconazole 🤦‍♂️

Can anyone recommend a good record keeping app for spraying records that doesn’t break the bank?

Post em Prosulfocarb mixes has been a saviour on ryegrass this season- getting rain at the right time is the challenge to get reliable results. This is 7DAA done between rain events in a mix. Sakura/logran underneath IBS at sowing. To the naked eye these are looking really crook

@JarrodAmery Not sure how they stack up against each other, never used the revystar. We need rain to justify, by then we could be at 30% bloom and Prosaro will be a cheap option as probably only need 3 weeks protection but still a long way to flowering for some unfortunately.

Applying 1lt Revystar on 44Y94. Each year it’s difficult to know which fungicide to use. Different costs for length of protection. Prosaro at $9ha is a good option but I’m going for a 6 week protection since I pay a contractor with an SP to apply it. What’s your opinion on this🤔

@robbert115 Is there meant to be a picture attached to this post somewhere Roberto?

I did a simple study spraying glyph resistant ARG with two types of glufosinate200 at 3L rate against 4 leaf ARG. One was generic glufosinate200 and I’ve added 1% hasten to the 3L. The other was Liberty 3L solo. Which one of the two treatments looks more effective 14DAT? 👇👇

@brodenholland Stick out so Mg sulphate through the boom, cheap as and mixes with most things done plenty off it, if your sure it’s Mg 3kg/ha be a good start even with a bit of zinc will probably help as well

Mg deficiency showing up in eastern block, might need to spread something over summer to address

@agriprof @robbert115 Sure, just trying to work out if it gives extra control if the oil is already in there as hasten has surfactants already

@Adspearce @robbert115 Yes it gives significant benefits. Glyphosate likes acidic water. 0.1% Li700 acidifies and is a wetter. At 0.2% Li700 becomes a penetrant like an oil, without having enough oil to do enough if an oil is needed. Hence in this scenario, an oil also needs to be added.

What adjuvant use with Terrador + Glyphosate spray for ryegrass. Also are you more inclined to use 20g (below label) or 40g? I’ve done a trial in pots testing all the 8 options below I’ll share in 2 weeks. Glyph-resistant ryegrass will then be double knocked w glufo + terrador

@agriprof @robbert115 Does the li700 give an advantage? If so what is it doing - Helping penetrate or other?

@robbert115 0.2% Li700 + 1% AMS + any oil on hand.

@HoolyMcg Do you use streaming nozzles with those rates or just normal nozzles? If so are you mixing anything with? Looking at doing some over east and just curious of the strategy as it’s not common. Cheers

Might as well scare the rain off with 100L UAN.

Bit of a trial going on here Disc Vs Tyne with Overwatch on canola on mixed soil types - this is the sandy end of the pdk. Pretty happy with establishment and weed control for a late break, more bleaching in the disc on the sand, not as obvious on the heavier soil.

@JarrodAmery Go to your supplier with some photos to talk to the rep and tell them it’s not good enough, I would be making a point if that was my customer!

Here’s the quality difference of the MAP I’ve received this season. I sieved the top left sample and got fines galore. This fertiliser has destroyed a silo and blocks our Horcsh airseeder roller within 3 - 4ha. Needs to be a quality control inspections before arriving on farm.

@brodenholland Pre-em options are the biggest struggle I find with discs but you probably don’t have much option with that amount of stubble cover anyhow I guess?

Great project to be apart of, a challenging start to sowing but modern farming systems showing what can be achieved in less than ideal circumstances.

@JarrodAmery @theGRDC Keen to hear the outcome

Has your fertiliser been arriving on farm damp this year? If so, listen to my clip and add any constructive questions you might have to help me. Thank you. ⁦@theGRDC⁩

@robbert115 Always appreciate your research Roberto, thankyou very much for everything you share!

Last was 1L DropZone applied pre as all other options tested. It seems to have soil activity against fleabane seed germination. Serradella suffered from same herbicide action while appears to be relatively safe on Tedera. No activity on ARG as expected.

Small study to see what 11 pre-em options can do against fleabane resistant to paraquat. All sprayed 2 weeks ago pre-em onto a mix of shallow-sown seed of ARG, fleabane, serradella and tedera. Next is layout of all 12 herbicides and then individual zoom-in photos.

@nozzle_guy Thanks Tom, appreciate you joining us!

Great to be with #GRUpdate in #Perth, #Bendigo, and #Dubbo this week, and looking forward to #Goondiwindi and #Pallamallawa next week. I will share our recent research, but am very keen to learn more about the spot sprayer revolution happening there.
