Grassland Paddocks & Pasture Weed Control

Weed Control

Controlling weeds in paddocks is important because they:

  • Compete with grass for space, light, nutrients and water.
  • Are unpalatable to your horse or pony.
  • Can be poisonous, e.g. ragwort or buttercup.
  • Take over the paddock and if left unchecked limit ability to graze.
  • Can spread to neighbouring properties.
  • Make pastures look messy, untidy and unkempt.

There are several control options. These include:

  • Dig them out - OK for small numbers.
  • Cut them down - temporary effect as perennial weeds will grow back.
  • Use a herbicide – via a knapsack or boom sprayer (ATV or tractor).


Which herbicide to use?

Much will depend on how many weeds are present. Knapsack control works out more cost effective if weed populations are below 5% (count number of docks 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.
  • Short grazing interval so animals can return back to paddocks quickly.

Envy® and Grazon®Pro meet these requirements. They are professional use products which you can use if you hold a PA2 (for boom sprayer) and/or PA6 (for knapsack) certificate of competence (visit  for details of your nearest course).  If not then seek training or employ a spray contractor or local farmer to do the job for you.
