LINSEED HERB OPTIONS

[tw15]

Whats still left to use in linseed
problem weeds broome
wild oats
meadow grass
fat hen
and nearly every type of common arable weed
please score them as
1 * = cheap
2* next up in cost terms
3* expensive
trying to get as much info so i can have a bit of a idea before a chat with the agronomist

Loads of stuff - two approaches in my view.

Avadex pre-em.
Callisto pre-em.

or

Burtyflow + mixer post-em for BLW
Fop / Dim post em for grasses

I go for the post-em, as pre-ems, unless very low weed burden, pretty much guarentee post-em followup. Butryflow + mixer = fairly cheap. Basic graminicide for anything except BG also cheap.

Brome 3. Avadex pre em only
Wild oats 1. Avadex or cheaper is Falcon/Orient//Shogun post em
Meadow grass Don't know since Aramo was withdrawn
Fat hen 2. Eagle + Butryflow post em unless you have any old label Chekker.

I used Callisto pre em last year in a field known for ryegrass and cranesbill. Good cranesbill control and less weed pressure later but no avoiding the same post em treatments so I won't bother this year.

You do have metazachlor as a pre em option which might help reduce a big broad leafed weed problem but again, I don't think this will suffice. Beware of label restrictions.

I used callisto last year but although it helped not using again. Used metazachlor pre-em which is reasonably cheap (does AMG?)but unlikely to work in these conditions. Hope to follow up with just butryflow unless wild oats rear their heads. What mixer are you adding to butryflow @static? Half rate SU? Fat -hen used to be controlled very successfully with a whiff of MCPA.

There is a number of pre and post em options available for use in linseed. Some have on label approval and some are under EAMU.

Pre-ems: Avadex, Callisto and Bustisan S / Sultan 50 SC are all approved under EAMU. We strongly advise against using Metazachlor products on chalk soil and would prefer growers to use Callisto is these situations. We find Callisto to be very crop safe. By applying a pre-em for Broad Leaf Weed (BLW) control it creates a breathing space to go after grass weeds, especially Blackgrass with Centurion-Max (EAMU) post emergence.
In Non Blackgrass situations there is a range of fop and dim chemistry for the post-em control of Grassweeds.
Post-em BLW weed control options include Eagle, bromoxynil options, e.g. Maya. There is a range of metsulfon-methyl, e.g. Jubilee, options available for Linseed, however these can be hard on the crop, so tend to be an option of last resort, ESPECIALLY on chalk soils. There is a number of clopyralid options , e.g. Dow Shield 400, approved for Linseed. Finally there is a number of bentazone options, e.g. Basagran SG.
While no MCPA products are approved for linseed, there is an EAMU pending with the CRD.

Comprehensive list thanks. And whoever is carrying out this work re MCPA, well done.

I have creeping thistles in a new bit of land to me which currently has Linseed in. Looking at the shield label I am only allowed 1 half dose of it unlike beet where I am allowed half followed by full rate. So what is my best strategy please? Half rate shield followed by bromoxynil + SU? Neither bromoxynil or eagle have thistles on the label but I bet bromoxynil will have a go at it. Or the other way around? I favour the first. Obviously MCPA will twist them up any news as to whether approval will be granted this year? @Premium Crops @static @Brisel any thoughts please. Thanks

No EAMUs showing on the HSE website for MCPA in linseed yet. I have no idea who is looking at the EAMU either. I don't think Eagle + Maya is strong enough to do thistles properly.

I know that this is expensive, but think laterally on the Shield - there is more than one form of clopyralid approved for linseed;

Without reading the labels, you might be legally able to apply more than one product. What I can't answer is if there are crop safety or residue issues with higher doses of clopyralid that might be the reason for restricting the dose in the first place.

I think avadex is a bit risky on late spring crops. Can't see it having much impact on blackgrass if used on linseed this spring then it's getting pricey to follow up with Centurion Max.

On the other hand, I do spend a bit extra on Callisto pre-em even though 90% of the time I need to follow up with something like Eagle & Butryflow. Callisto is crop safe and quite reliable even in a dry spring and it allows me some flexibility to pick my timing before I hit the crop with an SU.
My thinking is that one of the justifications for growing spring linseed is to allow early(ish) and low cost establishment of winter wheat which necessitates minimum weed seed return. It's nice if you can get WW to T1 with only a whiff of Hurricane pre-em before you tackle BLWs.

However, Callisto cans are terrible for washing out!

I left a 'trial' plot of missed callisto last year and l wasn't that impressed tbh.

Any thoughts on using Metazachlor on autumn linseed? I've tried callisto on spring linseed and was very disappointed. I will either use avadex or meta as a pre-em. The meta will be cheaper and easier for me to apply and obviously won't be as good on BG but should help will all round weed control. Is the reason it isn't often recommended crop safety?

 

[teslacoils]

Target weeds? Metazachlor on spring linseed is hot and the problem weeds on our clays are better treated post em.

Hard to say. Not been in this field before.

 

[ollie989898]

Your strategy will depend on what your expected weed burden is. Butryflow does some weeds but it very safe on others.

Need a good seed bed for callisto to work well.

 

[yellow belly]

in later drilled crops avadex takes out all the early germinators if it rains if it does not rain then the bg does not
centurian also take out most grass weeds or delays their growth so that they have not flowered before the desication

winter linseed has crawler in addition which being post emergent can be used if bg has germinated

the point of a non cereal break crop is to control the grass weeds
some of the cost can be spread over the rotation

I wouldn't use metazachlor as pre-em on linseed. It ha can be harsh on the crop, pre or post. It will not kill the crop, but Premium Crops research has shown it reduces long-term vigour in linseed.

So do the su herbs, but there's no choice really.

I like bromoxynil post em

At least plants are a bit bigger at this stage and less vulnerable.
