Clear field Rape varieties

[Mr Charisma]

I grew clear field PT 229 three years ago , through the growing season I always felt it was just falling behind the other varieties but it yielded reasonably albeit 35 cwt against 40 cwt for the Harper and 41 cwt PT 119 ,,,,,,, but the clear field did it's job in a strong charlock field .

So this next season my rape is on all strong charlock ground ,,,,,, having had crop damage two years on the trot with fox albeit with very good charlock control I'm looking and have been told that there are some new clear field varieties in the field this year ,,,,,

Anyone with some advice !!!!!!

From what I understand, as soon as the CL gene is bred into a variety, it loses a % of yield.
The yield loss has to weighed up against herbicide damage and poor Charlock control.

DK Imperial here has been as vigorous as Elgar and Alizze this season.

I would say if you are expecting a big Charlock problem then go with the CL variety.

There are a number of CL varieties about now but they will all be a few per cent off the best. A number of these have not gone through official trials or are just going through now. Imperial will be the biggest in the market and a number of people here will have it for the first time this year I am sure. After that Veritas from DSV has quite a few hectares out there.

Don't bother with PT229CL. Second year of growing it here. It did 1 t/ha less than everything else last summer but I'd already got the seed for this year's on farm. Weak on light leaf spot, blind flower sites, highly sensitive to clubroot... I chose it because it is short and early to mature, so would have time to blow the combine down after harvest before dropping CL seed elsewhere where I'm still on normal varieties.

As above, CL varieties carry a yield penalty. 5% less than everything else in TAG trials last year across all CL varieties. The CL herbicides have a lot of gaps in the weed spectrum too, but they do cover the major ones like poppy and charlock. If you've grown HEAR previously then it will clean out volunteers. It's surprising how much of your osr crop comes from previous seed when you see the CL herbicide at work! The Cleranda + Dash stunts blackgrass nicely too, giving you time to wait for perfect kerb/crawler conditions later on.

Why grow it? Marginal osr land due to weeds. Remember the erucic acid claims last harvest? It's a useful management tool and adding a litre of CMPP to cereal BLW programmes afterwards to cover CL volunteer control is hardly expensive. Cost wise, after 2 years the CL hasn't worked out much cheaper seed & sprays but not putting a pre em on does give better autumn vigour and at least most of your spend is later on in case you're worried about slugs/flea beetle wiping it out in the early days. If you're on bottomless charlock infested clay and don't fancy spraying Fox in January then this is for you.

Do the sprays reliably kill cranesbill and hedge mustard?

From our experience, hedge mustard is a prime reason for growing Clearfield. The Cleranda does the job on that but not cranesbill.

PT229 had a tough start here and did not perform as well as we had hoped. The charlock control was excellent, did did have a serious poppy issue last year, we think it was the clearenda going on a little late. Have imperial and aquarel this year I am very pleased with both, the imperial is tall. I do have lots of charlock and have always had problems using Fox so the clearfield suits me well. The charlock losses are much greater than the yeild loss from clearfield. I have extended the OSR rotation but dont want to drop the crop as the alternatives dont fit the farm.

This. Small cranesbill is killed by Cleravo but not bigger stuff. Quinmerac helped with cleavers. Your only alternative for hedge mustard in osr is Centium pre em.

Galera would be a good companion for the CL herbicides as it mops up what imazamox doesn't cover - mayweeds, bigger cleavers & thistles

I have a field that needs a break, that grows World class hedge mustard to the extent of choking out the rape. Unsure if I am brave enough to try it.
Like the idea of not being front-heavy on pre -ems on a crop that CSFB might finish off.

If the weed spectrum were cleavers and charlock, would you be happy with the control of both from the CL herbicides plus Galera / Shield later to control them all? I hate cleavers.

 

[Green oak]

Any ideas on the price of seed please.

 

[Barry]

Some varieties about 5-7% more than normal hybrids. Some are closer to normal hybrids.

It's such a risk to rely on Galera with the timings now, that I used Centium pre em, then Clearavo.

A good bloke to ask is @farming4profit

 

[Mr Charisma]

Thanks for the replys , my own experience was very good control of the charlock ,,,,, where we went wrong was not controlling the volunteer wheat early enough , because the cleranda controlled volunteers we waited for as long as possible to get all the charlock that was going to germinate by this time the volunteers had become a bit strong

 

[Brisel]

I've always done the cereal volunteers in September so I don't have to bring the October Cleravo/Clesima timing forward.

There is one new Clearfield variety that is up there with conventional hybrids, but seed in short supply (shorter supply). Prices are not bad at all now as most key breeders have one, so competition is good. I note original poster is in Stratford upon Avon - I am passing through that County on 12th June, would happily call in to discuss in detail.

 

[Clive]

We have Veritas and ptcl299

Veritas miles better than the 299

Both very clean crops re weeds

Grew some Veritas last year, on a par with Imperial, but was late to mature last year.
