Fat hen control in spring linseed

[Farmerwilson]

Evening all

Wondering if anybody had problem with fat hen in spring linseed and which was the best product to use for control

Regards

Metsulfuron-methyl (Ally, Gropper etc) will do a fine job on that . From the crop point of view apply as early as possible as can be harsh at later timings. Adding a Zinc foliar is supposed to help.

Thanks for the info I'll look into it

I used to add 0,2-0,3 l/ha of mcpa 750 with good result.

Very true, used to be very successful and with the advantage of not being an SU. Used before flower buds emerged gave the crops a tickle but grew away well. Don't make the mistake of forgetting which field you are spraying.. Or that would be naughty. From memory the maximum dose was 1.2l of 750g/l used alone.

Maya according to the label, found out last year but didn't try it as crop was to far forward

Bromoxynil is the daddy for this. Cut-off is about 6" tall linseed. But something like half a litre of butryflow will do the fat hen, and other pains like bindweed and volunteer OSR / charlocks. It will be the mainstay of my spring linseed BLW control again.

Thanks for your help, we tried ally last year but didn't really touch it

The view now is that Ally / Jubilee is a bit hot on the linseed crop. Chekker is the SX of choice it would now seem. We use the bromoxynil as the base, and add in others as needed.

Usual "I am not an agronomist" caveat.

Useful comments above re MCPA.... really surprised the Ally approach hasn't worked for you though, always been pleased with control here.

Very true with 1,2 l/ ha. I tried 1,5 l/ha instead of 0,15 l/ha once (due to a heavy bachelorparty), it survived but looked odd for some weeks

Metsulfuron stunts the crop and reduces yield. Amidosulfuron and a litre of bromoxynil sorts it out easily. Chekker is no longer approved under an EAMU nor is it likely to be.

Mesotrione (Callisto) pre emergence helps but also under an EAMU. It didn't mean I could do without the post em follow up.

Had very poor control of fat hen from SUs. Buttyflow the way forward.

Many be but mcpa has more bangs for your bucks if it were legal

Anybody on here considered metzachlor under an EAMU as a pre-em?

Yes pre em of sultan 50 which is
500 g/l (44.3% w/w) metazachlor.

Pleased with it? Would it be 1.5lit/ha? Can't remember, while since I used it on OSR.

Yes your correct 1.5ltr/ha then a top up of something post em, Will be going on soon as it arrives Monday so fingers crossed it helps

I'd forgotten about that. It would do as a start to broad leafed weed control and buy you some time before the follow up contact spray.

That's what we thought, it gives u abit of time with getting around other crops and follow up with a contact
