Low disease year

[An Gof]

So much on here about being a low disease year. Today the Recommended List trials at West Charleston in Devon were demonstrated by NIAB Tag. There will be some big responses to fungicides in these trials

Went to a local trials day ,recently,and pretty much the same.Some of the untreated plots were plastered in disease. I think those that may of skimped on fungicides may be regretting it now.Some of the treated plots were also carrying quite a bit of disease,notably Septoria and some yellow rust.
I thought at one stage there was real potential in the crops but ,alas,feel the recent weather and lack of June sunshine may restrict it somewhat.

Blimey went to one this week and there was very little difference between treatd and non treated, sprayed some late T3 for someone today and there was a lot of bydv in it

Yellow rust isn’t representative of a high or low disease year in my view. It’s the wet weather diseases which are hard to control in all crops- Septoria blight chocolate spot etc.

However I have been surprised just how aggressively Spectoria pressure has ramped up from very little 2 weeks ago

Ps are those winter oats ?

Yes, winter oats new candidate variety called Galloway from Senova

Went to some trials yesterday, where the un treated were as clean as treated, but seen other trials locally where the untreated was full of disease.

I was a bit puzzled by those untreated plots, there was zero yellow rust even in the varieties with poor disease resistance. Perhaps the spray operator wasn't paying proper attention and forgot to turn the boom off for one of the sprays?

Shows the importance of treating for the season, area, variety etc. Looking good here with a reasonably low spend (£65/ha). Next year may be different and double that may be appropriate.

Location location location .

 

[AndrewM]

Yup, disease pressure varies massively around the country

 

[yellow belly]

local rainfall and temperature brings on disease
very little on the top 3 leaves in trials on the dryer sites as is always the case

Should have seen the Elation wheat at West Charleton (in the treated as well as untreated plots) - no rust so all the dead tissue was septoria. £231/ha of RL fungicides couldn't get on top of it.

Lol. Time for an upward shift in minimum disease scores on the RL then......

It was a stunning demonstration and variety site yesterday and another great reason why NIAB Tag membership is so valuable. The point i was trying to make from the thread was that there has been a huge amount of discussion on TFF that this is a very low disease level year. and for many it has been. BUT location is everything and the variation is immense. So when some blatantly ridicule the fungicide spend of some people and the applications they choose to use they may not be fully aware of the differing levels of pressure.
I was so shocked at the Crown Rust pressure at the site yesterday, only 30 miles from me, that i had a good look around my oats when i arrived home. Thankfully they are looking OK ....... but they have had three fungicide applications this year ..... and from what i saw yesterday that was money VERY WELL spent.

I've been saying all over westerly meetings that you don't touch a variety with a septoria score less than 6. Full agreement from the visitors at Devon yesterday.

Apparently many growers around there are putting four sprays on oats regularly. We're going to modify our fungicide trial treatments as a result.

What about spring oats, how many should they have ?

Usually say one is enough but in dirty years (and probably every year in the far south west) two is necessary (but no more)

I can't get away with one. Early cheap one if crop is thick and a late one for rust.

Last year I did two but it still had crown rust, this year they grew so fast while I was busy doing haylage etc I missed the first one so used a single dose of .6 siltra and they are still clean and look quite thick, both them and the s barley have been really cheap to grow this year

Which set of plots? Sutton Scotney?
