Charlock in OSR

[Jimbo26]

Hello,
I am growing OSR this year on some ground that has had problems with charlock in the past. Apart from growing a Clearfield variety I wondered whether any one had some tips on how to control it, such as a weed wiper.

Thanks
Jim

What does your agronomist say ?

Hope for some hard frosts!

Direct drill the rape

Hard frost best if all.
Fox is very hard on the crop, can see to the inch where you miss a bit.

ethametsulphorloran Not spelt right but that will clean it up. It’s a dry flow able powder.
‘it’s been around for over twenty years so should be cheap too

Hope for bright sunny days (Hence the frost relationship) before and after Bifenox application, and drill with a little disturbance as possible.

We call it Salsa here, and it's the cause of much rage. The Irish have it, yet we do not.

If the charlock is really bad it will smother the rape before winter and bifenox. Clearfield is really then the only option.

In France we use Callisto (mesotrione) 0,15 l/ha + Cent7 (isoxaben) 0,2 l/ha at 6 leaves or just Cent7 on its own if its not that many of them.
Works best when its cold.
I think both these actives are approved in the UK just not on rape.

Top it on a frosty morning to just skim over the osr. Hard frosts over winter will do the job but there’s no guarantee of getting them.I have used a flail mower but this year the tractor wheels did damage the rape plants it drove on as the frosts were so hard after topping. First year I used a spearhead batwing topper but the skids damaged plants especially when turning. Flail mower works well as it’s linkage mounted but only 2.4m wide so it’s bit slow. Combine yied meter is not showing any losses on the area mown. The crucial part is timing the topping before the osr growing point gets too tall. Charlock has died off on the 3 years I have done this.

I have a field that will never have osr again because of the charlock, the only real success I have had controlling it is Clearfield. Fox is just too temperamental to use.

A split application of Fox can sometimes work better than a single high dose. The first application sensitizes the charlock, the second then kills it fully.

Clear field is the answer for charlock .
No question about it.
