Killing sitka spruce

[Choochter]

I've got some sitka growing where I don't want it. Some seedlings are an inch tall, some of the trees are 3/4 ft.
What's best to kill them, please?
I've gone round the area with gallup360 killing other things but haven't done the trees.
I've also got GrazonPro. What's best to use?

They seem kind of waxy so timing will be critical, if you could catch them when new growths are most vigorous almost anything would make them very unhappy.

What about cutting the bigger ones and using a stump killer on them?

Bash ‘em up a bit first before using the glyphosate on them?

Havent got time for that just now, just want then dead/dying

Not out in the open to rotavate?

Copper nails are supposed to kill trees, so I heard once. Not sure how true it is. T'would be slow though, probably.

Can you get a strap on them and pull them out with the tractor?

Sheep would surely eat them?

Goats maybe

I still reckon that the quickest way you’ll kill them is to mess them up a bit (heavy roller over them a few times, or pretend they are a smug prime-time wildlife presenter of your choice and take a blue pipe to them ) then spray them again with glyphosate.

I dunno how well Grazon pro would work; Sitka is going to be most like bramble/broom/gorse, but they recommend spraying June to August, when actively growing.

they are in what was a riding arena, there's hundreds of them
I think spray is the only easy option

Flail hedgecutter? Then spray again. Brushwood killer.

Some twit has been planting (sitka) in the heather on moor here mostly alongside roads so not natural regen - I expected them to die but have been unexpectedly resilient to exposed site and sheep browsing, though the grazing pressure is not very high
They have mostly been cut off at base this winter they don't regrow like coppice.

If they are small, put road salt around them

the topper is a possibility, I could set it at 6 inches
still need a chemical though for the wee ones
