Blackgrass chemical attack

[Flat 10]

Not needed to go down that route, also it is very costly compared to topping up FFCT

But compared to defy?

Avadex certainly has a place. But I have always kept it for wheat after oats. The aim here has always been to avoid any contact sprays....except roundup.

3.0 lt Defy £18 / ha - Avadex £38.50 plus contractor charge

Is there any proof that avadex works any better tho if so then surely worth the extra cost

There is.

All our no tilled wheat after osr has a sprinkling of blackgrass. Too much to rogue but not enough to affect yield but will need a spring crop next. I dropped the pdm out as it was so wet and I thought it would harm the crop (I still think this was the correct decision). I think it’s just something we have to live with to be honest. I have some quite clean crops considering how early we drilled some and I am sure if we had cultivated they would be a disaster.

No matter what chems you chuck at it unless you address rotational, drainage and management issues changing chems will not do anything. As we all no you can do the exact same things every year and get completely different levels of control

Would bg seed hends out now be viable if sprayed with roundup. If hand routing now some come up by all roots and some brack of just under surface question will they regrow to produce seed head . Only small patches but want ro try and nip it in the bud. Only found two small patches last year very near harvest some heads then we're beginning to shead. Information much appreciated.

If you're roguing now you need the whole plant out. Here in lincs it's just poking out and starting to flower. I'd say I've got until Lincolnshire show week (so roughly a month) to pull it before it starts to shed / the wheat ears scratch me too much.

There are trials which show it both ways. Personally found when drilling later end of October don’t justify extra cost.

Does anyone know of luximo will offer much extra? My friends who works for basf says it’s good but he would!
On avadex I’m really not sure how much it brings to the party for extra cost and wild and tame oats seem to get through it. I had to Broadway my wheat after oats despite it having avadex, that’s costs a lot.

Avadex pre-em followed by 4 litres Crystal plus 0.2 litres DFF. But not all in one go if a heavy rain event due before peri-emergence.

Liberater.

Avadex the Cost is justified for wild oats anti resistance stratagy
pre emergence glyphosate as late as possible ( ideally day before emergence )
Notill drill deep so wheat takes a couple of extra days emerging by which time more of the surface shallow germinating bg is 1 leaf
after osr leave the volunteers till after drilling ideally 6 inches of fence cover this keeps the surface moister and allows the pre em to be more effective
use double spring break crops between wheat crops once every six years

I would imagine this (or a couple of spring barleys) will have the best affect.

Before al lour real heavy BG land went to AD grass, used to be ww osr ww w beans. Many have bemoaned beans, but bar one year always over 5t/ha. Best year 7t. Just prior to emergence atack of kerb, centium and nirvana (expensive-but not as much as ending up with bentazone) was leaving land almost spotless for BG-all bar tramline cracls in summer. They were subsoiled in and shallow powerharrow (or tow a lump of telegraph pole). Modern LD subsoiler points would make a better job thann we used to I would imagine. A good 10 inch spaced DD tine drill likewise. 6-8 inches deep. Always October-sometimes tricky operational conditions-but compaction they hate so much was if anywhere above them with a fissure to emerge from.

Spring barley followed by a spring non cereal
unfortunately now beans cannot have Avadex or clethadin I also spray off the weeds before mid august with glyphosate
linseed can have Avadex but planting later ( May) you need the right combine and time the glyphosate well
if black grass controll is the aim then drill no earlier than 10 th April with high seed rates

 

[teslacoils]

Crawler going. Kerb not far behind. Replan your bg rotations after that. Sigh.

When glyphosate is banned then we really are buggered.
Do they actually want any food grown in this country ?

Back to grass leys and the plough.

Back to grass leys and the plough.

But what is the point of grass if we cant have cattle because we cant spread sh!t and we wont be able to plough because it releases CO2
