Does bifenox do anything to cranesbill (5-6 leaves and 10cm across)? TIA
It's a big No no to say you used fox for charlock with the EAMU you have to say it's for geranium species but it isn't any good on it.
If you'd only used belkar 4 days ago you'd have been ok[emoji6] it's good on cranes bill by all accounts.
Fox has geranium species on the SOLA for application to osr but in my experience, does very little unless the cranesbill is very small. Smaller than you've just described. Your justification for the SOLA will still have to cite cranesbill though even if the main aim is charlock. Keep the rate up to the 1 litre max and use a decent methylated oil like Zarado. A good water volume and fine spray quality helps with coverage. I hope the crop is well waxed up.
The cut off date for Belkar was 31st December and 8 true leaves.
@Woodlander and @Oat may have a more educated view on this.
Not a lot to add really. The EAMU is for geranium species, but as you say, generally only works on smaller cranesbill, and control is usually a bit hit and miss. Problem is that it is your only option really at this time of year. Some people have had reasonable results with Astrokerb on cranesbill, but that may depend on what you have already applied. Belkar will be the way to go in the future if cranesbill is a specific target weed, but again, will work best when applied earlier to small weeds
Astrokerb twists it up but doesn't kill it all IME.
Not over impressed with Astrokerb here,esp when you think it's nearly double the cost of straight kerb.

Like @Woodlander I can't add much more. Fox has EAMU approval specifically for cranesbill, so in theory it should do something, but usually this is only when the cranesbill is small.Not a lot to add really.

Everyone uses it for charlock, but you have to record it as being for cranesbill. For use on charlock it often works best after frost has weakened the plants slightly. A split dose (1.5+1 L/ha) and adjuvant often help also.
The main other options for cranesbill are dimethamid-P (in mix with other actives) applied pre-em, or Belkar or Astrokerb post-em, but the level of control can be variable. Alternatively, you can use Cleranda on Clearfield crops.
