Revystar Experience

[SilliamWhale]

Agree this is probably what will happen and we will remain in thrall to stuff which breaks. Unfortunately there’s no money in deploying science to find methods that aren’t so breakable. Hence the merry go round continues!

I dunno if you are overreacting a bit.

I mean basically 2 litres of sdhi fungicide per ha for wheat and probably 1 litre or so for barley on average is hardly dreadful for the average yield boost we get from it year in year out. I'm still a fan of fungicides.


I often wonder if the chemical companies were less regulated could we come up with some cheaper products?

 

[PSQ]

The era of chemical agriculture and answers in cans is ending. Seems to have worked okay here but for how long?
The treadmill of our own making is going to fast now and agronomy needs to head down different paths.

Similar to modern medicine we're relying on different chemicals to deal with emerging problems.
I doubt any of us would dispute the validity of modern medicine and pharmaceuticals, and I see no need to pretend that there is a need to negate the validity of fungicides and herbicides.

Insecticides I can happily farm without.

Don’t disagree but we break them so quickly.

I’m not negating their validity at all, I am just uncomfortable with being so reliant on these silver bullets. Breakdowns happen quicker and new stuff comes through slower.

Tryed some Revystar and very disapointed with it for septoria.

 

[ajd132]

How has univoq compared to revy for those who have used it?

 

[benny6910]

I have done a little experiment with no t2 on some first wheat kerrin. Right hand side has had t2 revystar left has had no t2 at all but both have had the same t1 and t3. At the time of applying the t3 no real difference could be seen between the 2 but now you can see the difference.

Members of NIAB Tag should find this years fungicide programme trials very interesting. There were clear difference in programmes when I visited the Sutton Scotney open day. Bill Clarke has retired but he made it clear which horse he was backing

Has he retired??

Revystar is a very expensive can of pee waste of time on spring barley where the Folpet which most people said was the same are wrong crops are green as grass with Folpet no disease

Haven’t used revystar on anything here but not thinking much of folpet on my Laureate spring barley at paint brush stage. Flag lost green leaf far earlier than it ever did before with bravo.
This time of year the wheat always looks like it will be earlier to harvest than the spring barley but wheats have stayed greener far longer than the spring barley this year.

Might not be the folpet, maybe it’s time to switch to Diablo? but first time in 8 or 9 years I’ve been concerned about how my barley has been looking In mid July.

T1 spray

 

[Gong Farmer]

Yes

End of this month, to be pedantic.

 

[Brisel]

Folpet has helped here. Anything that didn’t get a T0 has higher septoria pressure now despite a robust dose of a Revystar derivative at T1 and T2.

Chemical companies face the biggest barriers to getting products registered for use in the first place due to ridiculous EU rules. Then there is the on-going cost of re-registration and the ever-present risk of them being revoked because of endocrine disruptors/water quality issues/product comparison or whatever reason the regulators can dream up next. It is for this reason that common herbicides/fungicides on minority crops were lost mostly and more will go in future- companies can't be arshed with the cost to get approvals for use for such small areas of cropping. If you are one of the big 3 chem companies, what odds does it make to you if 2,4DB/MCPA/Basagran or say cyanzine/simazine etc etc are lost? Oh epoxi is an endocrine disruptor? Shame, now farmers will be obliged to use more of our latest and greatest on patent stuff.

What should really be happening is the mandatory levy money that is collected off you all annually should be paying to help get old chemistry back on the list and keeping them there. Instead it gets spent on a collection of old guffers who count the years down to retirement.

 

[juke]

from what ive seen on our trials i dont think alot of revystar, i think the new corteva fungicide will be better money spent,

 

[Worsall]

Revystar/Myresa&Syrex very poor here. Shame if we can't trust and rely on the Dose Response Data from AHDB, the one thing I thought they do of value for my business.

Don't wish to sound like a stuck record, but the extended 4-5 week gap between T1 and T2, filled with rainfall, was enough to stretch any chemistry. I've seen poor performance this season (posted a pic somewhere) from Revystar and Univoq, no fungicide however new-fangled can be expected to give 4-5 weeks kickback.
Experience tells us we'll now go into three or four dry years with negligible disease pressure, which means adepidyn, when Syngenta bring it out, will have a much easier ride.

It has dissapointed me for ramularia on spring barley, timing was ideal at paint brush. Sounds like the addition of folpet has worked better.
