Nettle Control in Established Grassland

Nettles in an established ley can be controlled using Pastor* herbicides.

nettles

Make sure the nettles are at the correct growth stage - actively growing, but preferably before flowering - in order for them to take in the chemical properly and for it to translocate down into the roots. If they are too big then cut them and treat the regrowth, usually 2-3 weeks later.

For spot treatment around the farm, to stop nettles from spreading their seeds, use Grazon* 90, which will not only kill the nettles but docks and thistles as well.

Pastor

Contents 50 g/litre clopyralid
75 g/litre fluroxypyr
100 g/litre triclopyr
Apply when nettles are actively growing, preferably before flowering
Pack Size 2.0 litres
Dose Rate 3.0 litres/ha
Water volume 300-400 l/ha

The weeds must be actively growing.

Leave 2-3 weeks after cutting/grazing to allow sufficient regrowth before spraying.

After application allow:

  • 7 day grazing interval before returning stock to treated areas
  • 28 days before mowing for maximum translocation

Grazon 90

To spot treat nettles use Grazon 90.

Contents 240 g/litre triclopyr
60 g/litre clopyralid
Apply when nettles are actively growing, preferably before flowering
Pack Size 1.0 litre
Dose Rate 60ml / 10 litres of water


The weeds must be actively growing.

Keep livestock out of treated areas for at least 7 days and until foliage of any poisonous weeds, such as Ragwort, has died and become unpalatable.
Fields should not be cut or grazed for 28 days following application to allow Grazon 90 to fully translocate into the root system for long term control.
Grazon 90 is rainfast in 2 hours.
