What product was that Robbie?I've been told by the experts tribenuron is the kiddy on mayweed but this last few years I've been really disappointed with the control.
This year I used florasulam less than full dose has nailed foot high mayweeds that had flower buds on them.
I know it's too late now but might be worth thinking about for next year.
I was using sumir. Max dose is 0.15lt/ha and I went at 0.1 but did add some cheapo starane which made it equivalent to, I think 3/4 dose of spitfire.What product was that Robbie?
