Maximising BG control in spring barley

[Flat 10]

Thoughts please. Getting more in it than ideal these last few years. Similar approach required to winter wheat? Later sowing, stale seedbed, robust seedrate?
Pre-ems worth it if soil moisture available? Anything else? Don't know if I would dare wait after end of march here. Thanks

If you have to move soil in september
Bad black grass drill later
use Avadex

i notill and plant in April disturb no soil and loose no moisture and use a very high seed rate
cultivate in the spring and drill later will not work very well

Keep it simple. Straight into warm soil at the end of march minimising moisture loss so the crop gets in and flies. I never bother with a pre em in the spring and don’t skimp on seed, it’s one of the cheapest inputs if it’s home saved. If your land is light then earlier in march would be fine depending on the year.

As above, high seed rates and Avadex. You can stack 2 half doses of flufenacet products but always read the label first. If you need to move soil, do it in the preceding autumn.

You can reduce the seed burden considerably by a few spring crops but ultimately you will be selecting for spring germinating seed so alter your strategy occasionally.

our worst black grass control comes from late march or April no till disc drilling of spring barley here, so complete opposite to what you are experiencing.

personally I find the best way is to get as vigorous and big a crop as possible to swamp it out, don't knacker it with loads of herbicides.

Plant more seeds, later. Fert down the spout. Warm weather. I'd not bother with a preem as likely slow the barley while the bg will laugh at it.

My experienced SB growing neighbours ridicule my use of pre em on my occasional efforts with the crop. They say it’s a “total waste of money”. Bg is endemic here and they produce good crops which rely on crop competition. Normally after autumn ploughing and March drilling.

The worst bg control is march drilling then cold wet 4 weeks
later planting needs a much higher seed rate 600 seeds is not too much and n in the seedbed preferably 3 weeks before drilling

Sorry to hijack but got a similar problem with a field full of ryegrass. Light soil following wheat. It had Simba SL in September followed by a light press a few weeks later to remove the first flush. Left to grow over winter then sprayed off in January.
Was planning to drill with a Rapid without the system disc early March.
Any point in a pre-em for ryegrass?

How bad is it? Only you can weigh the cost against the reward. The stuff always seemed to germinate all year round for me.

I keep looking and thinking about it....but nah not yet.

 

[teslacoils]

Any thoughts on spreading 5t/AC chicken muck on, and drilling straight in? I'm going to drill straight into stubbles, at half rate, cross-drilling and with the front discs just making some light fluff.

Won't need any N after that. Just mind it will get leggy.

 

[teslacoils]

Will be rolling the chuff out of it once up anyway. Normally put all N in seedbed. Seedlings be ok sat next to plop?

Yes

That's what I'm worried about but it's had a good kill so I'm thinking low disturbance is the best option now?

It’s as good as March, anyone planting spring barley yet on their bad blagrass land? What seed rates for this time of year? Never drilled our cold heavy land this early before and 400 seeds seems quite high???

Use a spreader with discs not vertical beaters or it’ll be very stripey!

How warms the soil? As said above it germinates all year round and is much worse than blackgrass! You want whatever you plant to get up and grow so may be better leaving it a couple of weeks for things to warm up.

Just got in from dressing the seed now I could drill but not inclined too.

Mate drilled his barley 3 weeks ago on not quite so bad Blackgrass land, not a green spike anywhere.

Just worried that when it starts raining it won't stop.

Sprayed this off last week, does this count as bad blackgrass?

If it doesn't then this would, sprayed off a month ago, with a senior moment on the gps.
