To start OSR drilling next week?

[Brisel]

You’re looking at an expensive pre em like a metazachlor plus quinmerac or DMTP eg. Katamaran and Centium and will still have to follow up with Kerb and/or Crawler later. The costs for these equate to a pre em of Centium for cleavers and hedge mustard followed by Astrokerb later and big pre ems hold the crop back. At least that way you’re not front loading your spend and can wait to see what you’ve got later

What broad leafed weeds have you got? I assume it’s non Clearfield.

Not clearfield

You've pretty much said what I was thinking. To cover all bases I was thinking katamaran turbo which if it done the job and was all I needed it would be ok but you think I'd still need the kerb which is then ££££.

I'm not keen of centium I've heard several reports of it being harsh in the emerging rape.

Think I'll stick with metazachlor early post em once I know I've got a crop and then astro kerb.

Normal spectrum for light land. Not a lot of charlock, runch,hedge mustard, Shepards pearce could be one to think about which doesn't give me any options other than centium.

I usually use Metazachlor once the crop is passed the cotyledon stage but best read the label. Maybe a couple of true leaves, but not preem as I'm never sure I will get a crop and I think it knocks emergence.

Last time I grew it Metazachlor was sufficient at that timing and we have lots of cranesbill.

This year I am using centium preemergence because I have some In the store that I didn't get on in time for preem last year. Supposed to be good on cranesbill. I'll leave the Metazachlor out and use Astrokerb later if necessary for blackgrass. It's also pretty good on bigger cranesbill as well in my experience, certainly much better than Fox and Galera which didn't even slow it down here.

 

[Brisel]

Kerb or Crawler might not be necessary if you're one of the minority who doesn't have grass weed issues.

 

[Brisel]

Not much you can do with cranesbill in osr other than dimethanamid P pre em or Fox on a frost later. Some new Arylex chemistry coming next year I believe, which will help.

Edit: just looked up Belkar which you referred to earlier for the Arylex. http://arylex.eu/belkar-launch-hungary/

I didn't think Centium (clomazone) was that effective on Cranesbill but I could easily be wrong. Maybe check with your agronomist.

I don't think clomazone is any good on cranesbill either but would be happy to be corrected on this.

Serious amount of rain now. No worries about lack of moisture now.

 

[ollie989898]

I'm after a bit of advice.

In the absence of any problem grass weeds other than wild oats -which can be tidied up with fops/dims, is it possible to just use a pre/early post em and not bother witb crawler,kerb or astro kerb and what would be the best mix.

I don't want to spend a fortune early and still need something later but if I can get away with just pre/early post em, I don't mind spending what's needed.

I know theres now belkar for later BLW control but that's rather expensive at the moment.

What BLW burden do you have?

A lot of people are now opting to drill farm saved seed and waiting until they have an actual crop at the 4 leaf stage before spending money on it. You have a range of good BLW options now. Not a catch all by any means but they are useful.

Make the best seed bed you can, it needs to be firm to give perfect seed to soil contact. You want a full and even emergence.

Have you got much more drilled since your first lump 10 days or so ago? Rain here all thurs and v heavy friday afternoon, to wet for drilling on sat, thought it was going to rain yday but hardly did but was out anyway, got a start this morning and rained off at lunchtime. Forecast good from tomorrow onwards though!

Did 60ac on Saturday, but apart from that none other than the 300ac we did a while ago. As with you, could have probably done some more yesterday, but had a lunch booked and was thus slightly flat-footed.

 

[limestone brash]

the only blws I've managed to control in rape once they reach any size ie at the Crop definitely viable stage are thistles and mayweed (clopylarid)
For me pre em is essential in rape
I’m always amazed to hear of people on here who don’t touch their rape till Christmas
It would be a weedy mess if i did that!

Is there any data out there (@Feldspar) to show whether its worth spraying osr for flea beetle? Everyone knows that there are resistant ones but is it still worth removing susceptible ones? Are there any stats to suggest what percentage of the population is resistant or not? I'm certainly not advocating repeated spraying but rather wondering whether 0 sprays would be better than 1 or 2 as it might allow beneficials to build up?

I didnt spray at all last year for them, year prior it did bugger all so just let it to it's own devices, I got away with it. Looking this evening at the volunteers in the OSR stubble there appears to be a very small amount of shot holing but not as much as I expected, plenty of slugs about mind.

I have emailed you a slide. I would certainly not spray more than once. We sprayed about 25% of our area last year and I'm not sure I could really see that it made a lot of difference, but I'm not certain on that. Resistance levels are high in this area, so it's only going to work if you hit them and even then only a small %.

Job done direct after combine the same day. Drilling on dry no compaction ... And yesterday first serious Rain after ages...

 

[farmer steve]

Feels like it's never going to rain enough here to get any rape drilled successfully and keep it growing. Still hardly any moisture, only seem to get the odd shower off rain with a few mm. Few hours later can't tell there has been anything. Ground still rock hard like concrete.

20mm yesterday on top of 25mm Thursday and a 10 sat night means its pretty damp here. I think there was some Friday too. Tried to pull some OSR land up this PM and gave up as too wet. More forecast Thursday. Very surreal as was so dry despite us having 40mm in storms a fortnight previous. Can't believe how much it has changed and that you haven't had any.

Drilling again now. Just about going again with the Claydon. Just walked first drilled OSR and a nice new flush of most of the stuff that didn't germinate before. Few slugs (and not many CSFB contrary to my thoughts following a quick look the other day) so more pellets.
