Not enoughI think the AB6 option has the potential to bugger up the field for 2 years, there's a chance Blackgrass will set seed before a delayed spray in May. On a small field I fallowed last year it was heading early and I sprayed it off on 6th of april which makes me think that's not an option I want.
Also agree, most land needs a crop over summer so stick with spring barley I think. All it should need when drilled mid April is Avadex a cleaver spray and 1 fungicide, we all have the fert and seed waiting , anyone think 400 seeds /m in reasonable conditions (big assumption !) is NOT enough ??
