What are the best chemicals for controlling these? I know very little about it. Starane in cereals, shield in beet? Glyphosate in stubbles appears to be too late as they have formed daughter tubers. thought I was getting on top of them but they are really bad this year in a field that was spuds 5 years ago. TBH wasn't really targeting them this year and think they came quite late after herb application in spring barley.

Just call it companion cropping.

The extra carbs crop will come in handy once the Brexit food shortages bite.

Full rate Starane fluroxypyr in cereals & you can use it up to flag leaf, label dependent. Shield clopyralid is approved in lots of crops and arguably better, but is more expensive.

Do you need to control them? If you're thinking of a future spud crop then yes, you should try harder to clean the land up to reduce eelworm

Not essential but can make combining tricky and are competitive/expensive to control in beet.

In that case, they will be cheaper to control in the cereals. Your spud growing neighbours will like you more too, though I've never seen groundkeepers with blight!

Don't plough, pull tubers up to the surface so frost can get at them, with a drag of some sort. IPM, it is the way forward.

As above dont do anything that will bury them. Let the weather and beasties knacker them.

Starane/Starane XL lookalikes do them in cereals. Id use kyleo on them if they appeared on land between crops but they will be untimely I suspect.

A real problem in beet so clear them up in other crops.

Starane works in maize and grass too.

Shield is murder expensive compared to starane.

Preharves roundup is good, it may not visibly kill the tubers, but the viability of them drops big time.
