Thistlex Weed killer for thistles in paddocks & grassland

Key points:

  • Thistlex is translocated to the root - killing the entire plant
  • Rain fast in 2 hours
  • Thistlex weed killer offers fantastic control of spear and creeping thistle, it also has a good effect on the following weeds: nettles, dandelion, mayweed, clover, vetch, tare
  • Not suitable for treating Japanese knotweed
  • There is more of a demand for manure to part replace peat in some manufactured composts and more home-grown vegetable production. As a result products containing clopyralid, such as thistlex, should not be used on grass which is going to be made into hay. This will in turn reduce the likelihood of clopyralid residues being found in manure which would affect sensitive crops.

Application notes and guidance:

  • For best results, apply Thistlex when the weed is at the Rosette stage approx. 200mm across
  • Thistlex weed killer has no LERAP restrictions, meaning that it is ideal for use alongside water features, lakes and drainage channels
  • Keep livestock excluded from sprayed area for at least 7 days after spraying. Single application per year on established grasses (1 year old +)
  • To be used with a boom sprayer only
