Sick beans

[robin banks]

Friend of mine has asked what's happening to his spring beans. The photo above shows the start of what seems to kill the bean. It is affecting the whole field. His first taught was spray drift from a neighbour. But agronomist says that whole field would not be affected. As it's a funny shape field. It was doing well but suddenly is disappearing. Any ideas. Crop had slurry ploughed in before sowing. And has not been sprayed yet.

Not been sprayed yet? So no residual herbicide. But to me that looks like uptake of some sort of herbicide maybe from the previous crop. The recent rains have caused ours to suck up a bit of preem, but nothing serious.

The cupping might follow exposure to aminopyralid, perhaps in manure or slurry or residue from astrokerb on OSR.

We lost a bean crop from residual herbicide after OSR that also failed, but that was years ago in another place.

Fusarium foot rot, I had a similar experience, established well, looked good, and then in hot June weather it started to die off, literally the whole field.

Ditto for me. Not sure it looked like that though, although it was 16 years ago.
When did the field last have peas or beans?

Good point, always worth checking roots

my first thoughts was DFF, was the field in cereals that received DFF last spring?
You say it had slurry so could it be forefront carried through in the slurry from the grass,
I'd have thought it would show twisting if it was though.

Also dig up some plants and carefully was off the roots to see what they look like.

Sorry meant to say it had a pre emerge the day after sowing. Don't know which one but think stomp. I know the agronomist recommended whatever was used. I was in field tonight and it was sprayed tonight with a folior feed and seaweed trace element to try and pick it back up. But think it's no use a very nice crop looks dead. Personally I think it's something like forefront silage fed to cattle and the roots are now getting down into it or maybe some other spray. The land was in long-term ley. Got a really heavy dose of slurry before ploughing probably 5000 gal an acre of thick cow slurry. First crop of beans ever. Really good even crop. And disappearing quickly.
Agronomist looked at the roots and says they are healthy. It's dieing from top down.

Just spoke to my friend. Field was sprayed with forefront 4 years ago. And D50 two years ago. Can't be certain would about the slurry being from silage that had been sprayed with forefront.
He walked the crop Monday Evening and taught it looked really well. Wednesday evening he could see it was dieing. This evening it's really bad. Crop had been 12 inches tall on Monday. This evening it's about 4. There was a patch that looked good yesterday and even that is starting to die today.

Why do you put 5000gal/ac cow slurry on beans?

Why do you put 5000gal/ac cow slurry on beans?

To get rid of it
If I had 5000 gal acre available I'd be dribble baring it onto cereals in spring.

 

[robin banks]

Why do you put 5000gal/ac cow slurry on beans?

Not sure why but it's what he did. Mostly livestock farmer. And yes this ground would of been been drier than where the cows are so got a heavy spread.

Neighbour here had crops struggling after slurry application. He put it down to a contractor rinsing his sprayer out in his yard a few times throughout the season and that water was added to the lagoon. Nothing as major as that thou.
