T0 thoughts septoria control 2022

[robbie]

Mag and man.

I'd add to that a sniff of cu and zn.

With rusty varieties the T0 lays the foundations for the rest of the season ime

 

[Against_the_grain]

Just done .5 litre teb,1 litre scyon,1 litre maxicrop, 3l manganese today through my skyfall

That's early! Long way until T1 yet. Would think T0 would be another 10days here if we do one. Is this a T-1?

I agree. Round here timings are usually 20th mar/apr/may and with only 3 weeks decent protection I’m not putting anything on yet. Crops need manganese and first pgr split anyway so 0.5teb going in too when I do go. Last 2 years septoria has come in really late but then we did have adexar last year RIP. Ascra first then Revystar this year.

Where's round here

 

[Bigjon44]

Yeah skyfall needs a T0 little splash of teb for the rust and scyon needs to go on early to give it good time to work

What are peoples thoughts on what to use for septoria control at t0 this year? Didn't do a t0 for septoria last year, only teb on yellow rust susceptible varieties, but had too much septoria in may/june for my liking.

What is there?
Folpet?
Can you get mancozeb this year?
Triazole for the little bit of activity they have left? one of the foliar sulphur products?

Thoughts?

Given your location in Septoria centre, I’d consider folpet in your strategy.

Probably 3 x 1 litre of folpet from T0 to T2 with teb at T0 then two decent SDHI brews at T1&2. Many would raise an eyebrow at that! Another train of thought would be to take the money you spend on folpet and spend it on a higher rate of a current generation fungicide like Revystar/Inatreq at T1 & T2.

Of course, variety, weather, risk and timing drive choices.

yes, im not a big fan of folpet really. i think im leaning towards no septoria t0, but Revystar/Inatreq at T1 & T2, which will be pretty expensive, but i think it will give me more bang for my buck than folpet. i didnt spend enough at t1 last year as we had no rain at all in april and were thinking about getting thew irrigator out. then non stop rain in may and revystar wasnt good enough to get back ontop of the septoria

 

[Laggard]

Quite a bit of mildew in the wheats here in Suffolk, so will take that out at T0.

 

[Bigjon44]

With some copper?

 

[DanniAgro]

A biostimulant to help reduce stress and improve nutrient uptake so it says on the tin!!!

Where did you get yours? I'd like to try some this year but Unium can't be bothered to answer my emails! How much does it cost if you don't mind telling us?

 

[Bigjon44]

Scyon from Hutchinsons
Circa £90 for 10 litres
1L/ha

How many times do you use it?
some of these bio stims are very over priced.

 

[Bigjon44]

Only once at T0
I mixed it with 1L maxicrop triple , .5 teb and 3L manganese

 

[Bigjon44]

Gone a bit dry and stressy down here so hopefully it will prove its worth!!

 

[Laggard]

T0 for yellow rust only here = Tebuconazole (maybe with azoxystrobin too)

Is Teb a protectant of rust? I can’t find any rust in Kerrin but need to roll it and thought maybe spray Teb beforehand rather than having to wait 10+days after rolling?

No erraticant only. Just because you can't see the pustules atm doesn't mean the disease isn't in the plant. Best get some samples sent off to see what disease is there

 

[Gong Farmer]

If it's Kerrin, it's got rust.

For fungicides, no need to wait 10 days after rolling. Herbicides do most damage in this respect so, say, 5 days should be adequate.

I've given up on rolling, kicking my heals at the moment waiting to get beans finished then N2 on OSR before I get on to wheat, looking at these ideal spraying conditions I hope I'm doing the right thing
Skinnys on today all ready to go
