ProGrass

Herbicide

NEW fast-acting, wide spectrum herbicide for 2025

ProGrass is a selective herbicide for use in established grassland to control tough-to-kill perennial weeds namely: docks, buttercups, dandelion, common nettle, cow parsley and common hogweed.

The label supports a short cutting interval of just 7 days; useful for applications between silage cuts when it is not always possible to wait for the standard 28 cutting interval that is on the label of most other dock control products.  Note that for optimum reduction in weed biomass, wait for at least 21 days following treatment before cutting.

About ProGrass

Benefits

  • ProGrass is rapidly translocated to the roots ensuring long term weed control and allowing a 7-day cutting interval where needed.
  • Stock grazing can resume 7 days after application (this may need to be longer if poisonous weeds are present).
  • Rainfast in 2 hours.
  • No special manure management requirements.
  • The concentrated formulation means a lower dose rate than other options, so more convenient handling and disposal of packs.

Best Use Advice

  •  1 application per calendar year.
  • Apply from 1st March to 31st October in established grassland.
  • If the grass (and hence the weeds) have been cut or grazed, leave sufficient time to allow for regrowth to occur before spraying.
  • Application rate of 1.5 l/ha.
  • Must be applied using 3* drift reduction technology.
  • Apply to healthy, actively growing weeds at the optimum growth stage.

Crops

  • Established grassland (over 12 months old)
