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.
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.
