Barrier H vs Headland Polo - which is 'best'

[scimitargtc]

Title says it all - can't find a direct comparison as to which is 'best' from effectiveness to cost - barrier h is around £45 - £50 and we used it to treat 1/2 acre with about 150 rosettes - polo is around the same cost, quoted as 'up to' 10 acres and from the dilution rates would appear to be a cost effective alternative accepting is it a 6 monthly treatment... any comments?

Can't comment on Barrier H, but used Polo on ours & it took a long time for the Ragwort to die( over 2 months, & stronger plants were only stunted).

I would recommend spraying now & again in Spring if needed. We sprayed in May & it didn't do that good a job. Think label recommends September from memory.

Never heard of Polobut it sounds like Ragtime which I found crap and went back to Barrier H

I used headland polo to shift buttercups (ragwort under control) and its been great - took a long time to die off, but now beautiful clean paddocks!
