Does anybody know what these are munching on my stubble turnips?

Sorry to hijack your post but how. Late can stubble turnips be planted or broadcast

Depends on next 3 months really but around here never had much yield unless drilled before September but further down the country will have different results

The later you sow stubble turnips the leaf to bulb ratio increases perhaps go with a mix of stubble turnips or 100% Hybrid Forage Rape?

Saw fly larvae.

Saw fly larvae.

Yes, you can tell from the grey band running the full length of its body.

Never seen them before, doing a lot of damage. Can you spray against it?

Hallmark contact insecticide.

Hallmark contact insecticide.

Just check what’s on the approval label. There’s something in the back of my mind that Hallmark isn’t approved for them....could very well be wrong. Then again you might actually be targeting flea beetle

Try telling the caterpillars it's not approved, it's killed them the two times I have used it.

Turnip sawfly played havoc with some kale couple of years ago.

Damage not usually significant on field crops, but right little blighter on brassica crops for baby leaf production: http://ephytia.inra.fr/fr/C/16646/H...-Caracteristiques-du-ravageur-et-de-ses-degat

Pesticides approved for crop not pests so Hallmark fine.

Used cleancrop Corsair in the past.

Had it last year. They can turn the leaves to lace in a matter of days. Got just a patch this year but will probably end up spraying the whole lot.

aye that looks like some of ours, as I said never come across it before. Rang my agronomist but bloody bank holiday means god knows when he will send some spray

 

[Norfolk Hill Farmer]

Too wet and windy here to spray for a while anyway.

Turnip saw fly larvae get it sprayed and pretty quickly. They can make a mess of a crop in no time.

These things are weird, you can go year after year and never see any, and then you get a single crop that gets decimated for no reason you can fathom. They are voracious eaters, I've never seen a grown crop hit by flea beetle as bad. Fortunately they are rapidly nailed by insecticide but check your product approvals in case it isn't listed for use on the crop. Won't do any harm but your red tractor man won't like it at all.
