Apply herbicides to yellow bristle grass before seed heads ripen. Avoid moving stock from infested to clean paddocks – seeds can survive in dung.

Don’t make hay from paddocks heavily infested with yellow bristle grass or other summer growing grass weeds – the seeds survive in hay. In contrast, yellow bristle grass seeds do not survive in well-made silage and wrapped baleage.

If your run-out pasture was infested with summer-active grass weeds (such as yellow bristle grass) last summer, consider growing a forage crop for one or two summers prior to sowing the perennial pasture. This provides the opportunity to selectively spray the summer-active grasses and prevent weed seeds from replenishing the seed bank and infesting newly sown pastures.

Apply herbicides to yellow bristle grass before seed heads ripen.

Avoid moving stock from infested to clean paddocks – seeds can survive in dung. Don’t make hay from paddocks heavily infested with yellow bristle grass or other summer growing grass weeds – the seeds can survive in hay. In contrast, yellow bristle grass seeds are highly unlikely to survive in well made silage and wrapped baleage.
