Creeping thistle or Sow thistle.

[David.]

I have some ground going into vegetables and also into sunflowers.
The thistles are putting on good growth and everything else was taken out by a Feb Glyphosate application.
I really want to do the thistles properly, roots and all, but not leave potentially crop-damaging chemical residue.
What's good please?

Thistle X will do the job but there is a residue problem I believe.

Probably your best bet is another does of glypho

Kyleo will nuke them and any other troublesome BLWs. Be aware of label restrictions for following crops

ThistleX isn't approved for this use.

Kyleo is best but as above, beware of the following crop restrictions and drilling windows. What do they look like now @David. ? If the centre is dying but not the outside, the risk is that the thistles won't take in any more herbicides well.

Clopyralid is kinder to many more crops but isn't approved for this use.

Fairly robust health actually.

Would Grazon work?

 

[deleted user 837354]

Glyphosate for reasons of following crop safety I think would be best here. I definitely wouldn't go with grazon or similar because of the risk of leaving soil residues that could harm the next crop. I'd be extremely wary of using kyleo if this land is intended for veg or sunflowers.

The use of products with clopyralid or triclopyr here is a classic recipe for a disaster in your veg or sunflowers I would say.

What would we put with Roundup to guarantee success?

I would use an adjuvant. The glyphosate dose with your knapsack will be pretty stiff, too. The thistles are all about there at the right stage.

I suspect these characters hadn't popped up yet when you first applied glypshoate earlier in the year?

4lit plus adjuvant be fine surely

There is a bit of field bindweed too, so possibly something to get it into the waxy leaf? Agree that best addition to Roundup in these situations is usually more Roundup.

 

[Bogweevil]

Thistles look like a good target but it is hard to get enough killing power into bindweed when they are this small, bearing in mind the extensive underground roots.

Growing veg in perennial weed infested ground is soul-destroying Do you have a cleaner ground to use, and have a good old go to clean this plot this spring?

However if you are going for June or July transplanted crops you will have excellent opportunities for weed control before planting.

Thanks all.
Will go with Roundup Spryte at a good rate, and see what survives.
