Is there anything that will kill or get rid of wireworm in potato ground after old grass

A brassica crop, I think White Mustard too!

All you need to know about controlling wireworm in potatoes - Farmers Weekly

This season is the first where growers face managing wireworm without the key pesticide Mocap (ethoprophos) that has proved effective for some years in

No

Have you had any samples with wire worm in spuds this year ,
seems to be some damage ,coming from grass margins ,our spud man thinks ,

There is a lot of damage, my agronomist is becoming the uk expert on it! Old damage mostly on ours (it’s healed over, just a shallow hole mostly) but he says it’s going to be a big problem. He caught 19 in one trap on ours last week!

Any ideas why

You need to try the Garlic aspirin mix I sell. Leatherjackets, slugs, wireworm and some nematodes. Sold as a crop tonic but worth a try rather than do nothing. 1.0ltr/ha £109/ 5ltr del plus vat

Climate change……..

Not 100% sure, have dropped peas and onions in the rotation and gone to more straws. Had more green bridges between crops. Tight potato rotation, less cultivation’s.

When do you apply that?

When do you apply that?

For Lj's when they come to the surface to graze the crop. I would suggest if its grass going to potatoes I would put it on at the same time as glypho ( if using it) pre- ploughing.

Routine use of Mocap gone

Routine use of Mocap gone

More to it than that, never had trouble, never used nematocide , lost 50% of a block of piper to them on a field which is a bit too steep/awkward/variable soils so only on it's second potato crop in 25 years.
Been subsoiled twice in the last 6 years,otherwise nothing deeper than 3", and had radish based cc 2 years in 3.
Seems like one step forward, then two back here. Lovely bold , bright piper, they like the field but sadly it favours wireworm to.
