I'm aware it is expensive! Would rather not use bentazone. Could mix SU with the bromoxynil.Oh. What size are the thistles? Without the MCPA EAMU for linseed you're legally stuffed on these unless you rotate clopyralid labels for a second dose. An Eagle/bromoxynil mix has been ok on small thistles in the past & cleans up most other small weeds.
What is bentazone like on thistles? Nothing on the label and this problem is starting to look expensive too. @Premium Crops ?

I have used 0.25 lit shield which l think is max dose and only 1 permitted. Having to use a second one in the beet field next door.....Has the shield not done enough ?
The obvious choice would be glyphosate, but obviously can't be used on the surrounding cereals.Does anyone know if this Chem does hogweed/ cow parsley in cereals - and if not what might ?
MCPA + 2,4D will have a good go. Approved on cereals....Does anyone know if this Chem does hogweed/ cow parsley in cereals - and if not what might ?

Good point re growth stages. Maybe MCPA + Ally Max?Beware the cut off growth stages for cereals for hormones like these. 2,4D cut off is GS30. Same with Easel MCPA but certain circumstances can be GS39. Starane XL goes up to GS 45 depending on the cereal crop but I don't know how good this will be on those weeds.
Always read the label! Fluroxypyr is used for killing linseed in cereals...

Are you expecting any more effects? The shield has twisted mine up no end and now I am hoping the Maya might finish them off. Sprayed the trial this PM though it probably didn't quite get 2hrs dry......Here's what 2 litres of Troy 480 ( bentazone) plus a litre of oil does to thistles in beans. 5 days after treatment View attachment 520344
Linseed. Thistles already had shield.
B'-all? A colleague used to say the best way to get weed control with bentazone was to carry the can out to the field and drop it on the weed.Here's what 2 litres of Troy 480 ( bentazone) plus a litre of oil does to thistles in beans. 5 days after treatment View attachment 520344
Used jubilee in linseed in the past with zinc as recommended by @Premium Crops , problem was had little or no effect on weeds or linseed. Was very dry and when agronomist contacted DuPont they blamed lack of moisture. I have a hunch though that the zinc was a contributory factor.Use metsulfuron methyl. Du Pont Jubilee has a Creeping Thistle on the label. Be prepared for a stunted crop
