Forage Brassicas and CSFB

[Will7]

Do forage brassicas suffer from csfb in the same way as osr? I am in Mid Lincolnshire and have never had any problem getting the crop of osr established, it is in the Spring where the rot (literally) sets in. A forage crop would have been eaten by then. I have no luck planting kale in May, it is ravaged by csfb.

I was particularly thinking of hybrid forage rape and a leafy stubble turnip direct drilled between last years cereal stubble as early in August as I can which is how I currently plant my osr.

Many Thanks

we use radish for grazing it’s far more tolerant

Thanks Shakerator,

What radish do you use, and how long does the grazing period last?

Thanks

Forage radish and tillage radish being eaten here, drilled a couple of weeks ago but think it'll get away from it although not looked at it for a couple of days.

Charlock coming up in spring barley is full of flea beetle holes.

A leafy turnip is a good option for rapid establishment and can be grazed 6-8 weeks after sowing.

We have some forage brassicas treated with a unique combination of soluble nutrients and bio-active compounds. One of its advantages is Increased vigour and early rooting to help the crop at its most vulnerable stage.

It seems to be helping by what early growers are experiencing.

oilseed radish we have used for efa as part of a catch crop, as can be grazed after October 15th, but need to establish by 20th august so needs to be early land

oilseed radish more root than top, some radishes run to flower quickly giving more above ground biomass, although never going to get that much growth after cereal imo.

grazing period depends on stocking density and autumn weather of course

I've yet to have more than minimal damage to turnips sown in late July/early August. CSFB have a resting period around then.

To be able to get them established that early I would have to broadcast them into the standing crop, which is always an option I suppose....

Would Pacifica plus applied to wheat affect forage rape and stubble turnips sown after the wheat

 

[Brisel]

Possibly, if it was applied late & hasn't had much rain since.

csfb preferred my field of OSR to the one containing stubble turnips and forage rape,

Possibly, if it was applied late & hasn't had much rain since.

A neighbour has asked if i would grow some forage rape and stubble turnips after the wheat, i would DD the crop so maybe not a good idea
Is there anything else worth growing to graze with sheep that won't be affected by the Pacifica plus?

 

[Brisel]

Forage rye?

Take this with a pinch of salt, but I did a trial (spray miss!) in wheat with April applied Atlantis in a dry spring then direct drilled osr into the stubble afterwards. No discernible difference in the oilseed rape establishment and autumn growth. I had to go and Roundup the blackgrass & wheat out where I'd missed it so it showed up in the following crop.

Atlantis has a residual effect - TAG trials showed 60% control of BG from pre em Atlantis only. @Fromebridge will know more about that trial. Lexus, another SU, had an unofficial recommendation for pre em grass weed control in its latter days after it was shown to be pretty useless post em.

The results of my spring drilling of kale so far:

After beet, on sand, ploughed, power harrowed, rolled, drilled with unidrill, good establishment, minimal damage.

After beet, on medium to heavy land, ploughed, power harrowed twice, drilled with wheat as a nurse/confuser crop, rolled, drilled with kale, good establishment, minimal damage.

After failed direct drilled OSR on sprayed off grass ley, paraplowed direct drilled, poor establishment severe damage, complete failure.

The way it looks to me is that your best chance of success is to grow it on light land, in a fine firm seedbed produced my conventional cultivation following a crop that doesn’t also provide a good habitat for the beetle.

Considering how dry it’s been I am pleasantly surprised by the success of establishment by conventional cultivation. There has been more moisture loss than by direct drilling but seed to soil contact and speed of root development has been much more rapid and uniform.

Has it had su Chem how will you establish it , we learnt the hard way it nails it as it starts to grow.

I know it won’t be much use, but I was sent this absolutely savage photo earlier.....Stubble turnip...or was. Big beetle too.

Today, as far as i'm aware.
