Can High Rainfall cause Pre ‘Em herbicides to harm germination/germinating cereals especially on very stony/ flinty soils.

I only ask the above out of general interest , and not as a farmer in my own right.If they can be harmful to germination it must be a very difficult decision to use them or not in periods of heavy rainfall forecast

Absolutely because its washed into the root zone. We saw a bit of this last year.

It's tricky. As with most chem, the trick is being toxic to the targets might mean harsh to the cereal. Just look at any overlaps to see great weed control but potentially thinner crop.

I've a "Roddy hotmix" preem to go on wheat I'll be drilling tomorrow. Forecast on Monday could be bad or ok. Do I skimp on the chem? 12mm would be ace. 24mm less ace.

NIAB have done trials on various pre em herbicides to see the effect on crop emergence. The results are very variable between product and seed coverage. Certainly exposed seed didn’t fair at all well.

Cinmethylin (Luxinum) and prosulfocarb (Defy) are pretty hot on the seed. Triallate (Avadex) will also harm seed if in direct contact.

The added complications of stones are the shading effect and overdose if the herbicide washes off into the soil at the edge.

Is that farmed by the chap you drive a combine for? If so, that's not very "no till!"

I've got yards with less stone than that

By the looks of that photo, I think they forgot to teach us in school that along with Roman Roads that the Romans also invented the car park cart park.

Gets better

Perhaps SFI scheme best option

I’ve just bought a load of 40mm gravel for £25/t to put in a French drain.

I think you’ll find there is an endless amount just waiting to come to the surface in the Cotswolds. There are plenty of walls and houses built from it. Some must have been picked from the fields but you’d never know.

Remove the loose stone and you won't have a lot of topsoil left! The next leg or mouldboard will scratch more up from the bedrock below.

Needs grassing down then.

The south downs farm needed that, and it got it for the time my employer owned it.
The next one thought he knew better and ploughed it again.
It's grass again now.

Cotswold brash can still produce good margins. You just need to know how to manage it and not spend too much chasing Farmers Weekly/pub yields.

Been there done that took 2500 ton off 7 acre .allmit did was lower field one stone depth just as many when done
