Product Detail

Grazon Pro is a weed killer for docks, thistles, brambles, nettles, gorse, broom, sycamore seedlings and a large range of other weeds.

This selective weed killer spray takes over from the well-known favourite Grazon 90, and still continues to offer the best control via a knapsack on weeds such as docks, thistles, nettles, bramble and broom plus other difficult to control weeds in grassland and pasture situations.

Key points

  • Fast acting, grass safe and controls a wide weed spectrum
  • Herbicide kills to the roots, offering long-term control
  • Rain fast in 2 hours
  • Value for money: a 1L pack gives 16 knapsacks when mixed in 10L batches
  • Application using a knapsack only: check out our range of knapsack and handheld sprayers that are perfect for applying Grazon Pro
  • Apply 'medium' spray as defined by BCPC
  • Spray weeds thoroughly to the point of 'run-off'
  • Grazing animal exclusion: 7 days (longer if poisonous weeds i.e. ragwort are present)
  • If weeds cover more than 5% of the area to be treated - then Pas Tor may be more cost effective
    • Pas Tor is suitable for broadcast spraying via a tractor or ATV

See Grazon Pro label for all weeds controlled plus other top weeds below.

Using Grazon Pro for treating woody weeds

Between the months of June and August, it is the perfect time for targeting woody weeds such as bramble, boom and gorse. If these weeds are left untreated they can quickly spread through grassland and severely reduce the amount of grazing land that is available. Ideally, they should be sprayed whilst they are actively growing before they start to flower and have a good leaf coverage.

Sycamore seedlings

Many paddock owners realise how important it is to control sycamore seedlings if they are grazed by horses and ponies. Some seedlings contain the toxin hypoglycin A and ingestion can cause a potentially fatal condition called equine atypical myopathy. Although not on the label, Grazon Pro will give good control of these seedlings. Please note any extended grazing intervals if controlling poisonous weeds.

For equine paddock owners who do not hold NPTC sprayer qualifications, then the armature product SBK Brushwood Killer will give good control.

Grazon Pro Weed Killer also gives strong control on the following:

Annual weeds

Black Bindweed, Black nightshade, Chickweed, Cleavers, Cranesbill, Dead-nettles, Fat-hen, Field bindweed, Forget-me-not, Medick, Pale Persicaria, Scarlet pimpernel, Self-heal, Small nettle and more

Perennial weeds

Bramble, Broom, Gorse, Clover Trefoil, Coltsfoot, Common Sorrel, Docks, Fools Parsley, Giant Hogweed, Gorse, Ground Elder, Hawthorn, Hemlock, Himalayan Balsam, Japanese Knotweed, Lesser Celandine, Mallow, Mugwort, Nettles, Ribbwort, Rosebay Willow Herb, Self-Heal, Silverweed, Thistles, Vetch, Water Dropwort, Yellow Flag Iris
