Hi, I too have a major barley grass in pasture, problem but no funds to combat it by reseeding, fertiliser & soil analysis as we're now on the pension.
3 yrs ago we had an early 'break', good growth, sprayed with Glycosphate, great kill followed by more rain/warmth & regrowth. The seeder arrived, I asked him about all the greenery (b. grass of course!) but he said no need to respray, it'd be fine. We only have 12 acs, sowed 8 of them & you can guess the rest of the story. We now have about 80% of the damned stuff so, as you can imagine, the land is rather unproductive.
