    Taken on a farm which is historically a no till farm. It has developed a bad sterile brome problem.

    We are continuing the no till system but the brome is making life difficult.

    Land due for spring barley has had a cover crop on all winter but a fair amount of brome is also present. Sprayed off last week,

    option 1 is sow into dead brome/CC with spring barley and hope for he best, last years experience was mixed, regrowth brome in the spring barley hit yield.

    Option 2 bite the bullet and press the reset button and plough.

    any experience advice in this situ would be welcome. Thanks.
  2. I would spray off again with roundup post drilling to get those little extra bits plus add as much liberator as you can (.3l/ha) is the limit but maybe get your calculations wrong and add more up to .5l/ha or max out on DFF. Also up the seed rate. I think there are few other options - maybe sow 10th April to maximise regrowth beforehand.

    You will win the battle if your keen. I let brome get out of hand because I wasn't attentive enough - I'm slowly bringing it down again.

    Don't be afraid to plough if it suits you. I don't like doing it because I'm religious.

    Avadex granules applied post drilling?

    been in exactly this situation years ago, Sterile brome was our blakgrass ! resisted the temptation to plough and its has worked, land is very clean now

    spring cropping, rotational diversity and avadex / broadway star were all key parts of getting on top of it

    I would be weary of applying too much DFF in the spring in a no-till situation. DFF is a very persistent and stable molecule. It has a half life of 300 days I’m told. It may then interfere with the following crop/cover crop.
  6. I can't remember the habits of brome, is it worth shallow cultivating this field asap and trying to get some more to flush before another go with glyphosate?

    I agree with up the sowing rate. I would stick with the liberator though if it was me.

    Think most brome species are best left on surface to germinate iirc - they are slow / late germinators so late autumn / spring drilling helps a lot

    Meadow, soft and rye brome seed are not ripe when shed so need a delayed stale seedbed. Barron/sterile and great brome seeds are shed ripe so scratch the surface/ stale seedbed straight after harvest

  9. I agree with you. I suppose it depends on your rotation. Liberator/DFF on a spring crop before OSR will probably be safest off cultivated. I'm having to go to light cultivation for brassicas after barley because of the barley toxins playing havoc with brassica germination with the wet summers but I do wonder if DFF plays a role even 320 days after

    Spring barley is the wrong crop here. If you must sow barley, delay the drilling then use another dose of glŷphosate following a light surface cultivation, use a high seed rate and Avadex. Better still, sow linseed/beans/peas instead that improve the post em herbicide options.
  11. As I thought, wasn't a simple affair but memory went blank.

    Only scratch till this stuff or otherwise is it plough time.

  12. Avadex Covers wo as well as bg and brome in spring cereals

    I Use a zero tolerance in break crops and use broadway antlantis on wheat crops where there is a history of brome

    To beat brome in DD - its not at all tricky. Spring cropping is the key BUT broad leafed spring cropping, and in the worst fields back to back spring cropping with cover crops between them. The broad leafed crops give you the cheapest hit using quizalofop (falcon) and open up lots of chances for multiple glyphosate applications. Avadex does a good job. An example - Cover crop into spring beans into cover crop into spring wheat. The spring wheat gives you the chance to use flufenacet and atlantis.
