Established Grassland
Weed control
Controlling weeds in pastures is important because they:
- Compete with grass for space, light, nutrients and water.
- Are unpalatable to stock.
- Can be poisonous e.g. ragwort or buttercup.
- Take over the pasture and left unchecked limit ability to graze.
- Can spread to neighbouring properties.
- Make pastures look messy, untidy and unkempt.
Herbicide control options
A grassland herbicide will not cure the underlying problems but will help renovate the pasture to a more productive level for a period of time.
Knapsack control works out more cost-effective if weed populations are below 5% (count number of docks and/or thistles in a 5m x 7m area – this number gives the % weed population).
Choose a product that will deliver a:
- High level of safety so grass growth is unaffected.
- Grazing interval that is short so animals can return back to paddocks quickly.
- High level of grass safety so grass growth is unaffected.
