Caligula has got approval!!!!!!!

Where have you been?

 

[Flat 10]

After 1st Sep though I believe

 

[robbie]

Yes, why I don't know because it's only got a cut off of 7 days preharvest.
It'll fit the bill nicely for a t2 product prothio will do a decent job of mildew which could be handy this year.

Where have you been?

You should know by now, things are slower over here in noorfuk!!!!!

 

[DrWazzock]

What’s going on here? Looks like the crowns burnt out in some of the really drought stressed patches in the field. Hoping to lift early and get it away.

Have a read of last week's or the week before BBRO bulletin

So usually due to boron deficiency, downy mildew or this year due to weevil or beet moth larvae due to hot dry conditions.
Had boron but maybe not enough to compensate for drought stress. Couldn't see any downy mildew.
My main concern is how these roots will store, so I will lift a bit at a time and move it quickly, factory permitting. If these roots are dead and get in the sample I can't see it being good.
It's only patchy, not widespread but enough to make it look a mess and be of slight concern.
Don't think I'm bothering with any fungicide now as early lifting if possible.

I'm pretty sure it's not boron deficiency. If you want to check cut a root in half, boron deficiency will be blackened into the root, what your seeing is damage from weevil/larvae/grub what ever it is.

I think they'll be fine, from my own observations the dead damaged tissue doesn't go into the root so won't affect storage and I reckon they'll still grow fresh leaves from around the outside if the crown.

There's a lot of powdery mildew about I've got it around the headland so wl be going with 2 sprays, I'd think even on a early lift a single spray would still be well worth while. It's going to be atleast a month to 6 weeks before anything is lifted.

You need to cut the crown off and then in half. Bet you find larvae.

 

[DrWazzock]

Sorry it’s on it’s side. Kind of rot seems to start at scorched off crown then spreads down into root in the outer layers first. Can’t find any larvae. Some roots displaying what looks like purple root rot maybe as a secondary effect and getting quite rotten. An annoying but not large amount in patches worst affected by drought in the field though most plants are fine and healthy. Reckon we might be busy on the picking off table. Its a sort of very poor cursed field I reckon. Last year wheat all pink grains and ergot. Witchcraft. Was limed though and we didn’t skimp on fert. Maybe didn’t keep going long enough with the boron or maybe the 40 deg heat just roasted the middles? The plants affected were those that wilted worst in the heat. I reckon we always get the odd plant like that but this year there is a noticeable amount

Collect a few roots and submit a sample to the Plant Clinic at BBRO. Cost of postage to have another opinion above that of TFF. Postage be about £10 I expect. But get a sample sent in Monday so it gets in good time before the bank holiday weekend and the postal strike.

Here is link for printing submission form and postal address.

I saw similar a few days go on some fields near Stamford - overlying gravel and droughted. Was in the main odd roots. I cut a few open - didn't see any larvae - that seems limited to the A11 corridor. Assumed just one of those things.

 

[DrWazzock]

Thanks. Well I might send some off but I’d think it’s a result of drought stress and is what it is now. Worst on south facing Sandy area. Good land not really affected.

@DrWazzock A few years ago we had a problem with large plants just giving up and totally dying by going rotten.
Sent samples off to Dr Mark Stevens (BBRO) and it came back as aphanomyces, which then led to a secondary infection of rhizoctonia ( not rhizomania!)
I seem to think fusarium was also a factor involved. The seed dressing element tachigaren should help prevent it. Mainly light sand issue
If you pull up a plant not showing symptoms, is the tip of the tap root still healthy and white or going discoloured. ?

 

[DrWazzock]

I will have a proper look and get some sent off. Thanks. But from the crowns I’ve cut off it looks to be rot spreading from the outside layers onwards. That field had a bad fusarium problem last year with wheat. Lots of pink grains. Did not plough to avoid a blow. Probably loads of innoculant hanging around. Seed was dressed with tachigaren.

is limex all it’s cracked up to be

Is does look a bit like Rhizoctonia root rot. As said it would be best to send a sample into BBRO.

Is it in patches or isolated plants?
Do you grow maize on your land?

No maize.
It's in patches that were most severely stressed by drought, where the plant population and canopy is very open due to earlier wind blow and frost in the spring. The patches vary in severity of symptoms and size. It's not isolated plants.
Where there is a normal plant population the plants are normal, healthy and unaffected. I would have though the plants in the less populated patches would have suffered less moisture stress and been healthier but they are the ones succumbing to this condition. Maybe they had no neigbours for shade so just overheated. My agronomist doesn't think its serious just drought stress.

Anybody doing a second fungicide?

 

[Breckland Boy]

Anybody doing a second fungicide?

Yes did it a day before the rain as there was rust in them and I was going on holiday.
