Winter Beans - What Causes This?

[Cab-over Pete]

Aye-up,

I’ve walked over 100 acres of winter beans this morning and seen maybe a dozen plants like this one. Out in the middle of the field, nothing different about soil or anything else as far as I can tell.

Amazingly dry for mid January. It’s all heavy south Warwickshire clay and hardly sticking to my boots at all.

Cheers, Pete

A few of the shallower ones caught a bit of pre-em??

 

[Clive]

pre-em would be my guess ?

I have seen similar symptoms from pre-em herbicides, but not quite as extreme.

I am guessing the pre-em was applied quite a while ago, and the plants seem to be a decent size, so it seems strange to affect the odd plant so badly. If the plants were smaller and pre-em had been applied relatively recently, then such severe damage may be possible. Has a post-em treatment with soil activity been applied recently?

 

[Cab-over Pete]

I’ve no idea what’s been done.

However, I can barely see where the sprayer ran and certainly can’t see any plants damaged by tyres, so I would say a pre em was used.

It's common in beans.
Just a random plant here and there.
No reason as far as I've ever managed to deduce.
It's like the odd one that grows twice as fast, yet has no pods, bit of a natural genetic mutation

 

[Neddy flanders]

Genetic mutation causes albinism. Outcrossing crop so can happen. Definitely not herbicide as many more plants would be affected.

Thank you

Cheers, Pete

If new seed , some breeders put in tracers, in vining peas they can be purple or red. if home saved seed just genetic mutation. nothing to worry about.

 

[Cab-over Pete]

I doubt my customer is worried.

I don’t think I’ve ever seen a better looking crop of beans in January. They look superb.

I would doubt it is chemical, I have got to say the others in the photo look great.

You would know if it was chemical; I've seen a patch of beans where pre-em was spilled and the spot grew 'blonde' plants of all kinds that were severely bleached for several years.... Mutation would be my bet. The weird thing is, it must be a pigment issue but it does not appear to hold the plant back as he is the same size as his siblings!

 

[Cab-over Pete]

Taller, in fact. It’s not clear there, but it was definitely taller.

collect the seed from it, and multiply it up
New high yielding variety- cv. TFF Dead Horse

Taller, in fact. It’s not clear there, but it was definitely taller.

I’d call this definitely taller

If those are your beans today, I'm envious!
