Nobody does tough weedkilling better

Do you need to get rid of tough and invasive weeds?

If you have weeds like ivy, gorse, convolvulus, blackberry, wandering trad or onion weed then you need a weed killer you can trust to kill them, roots and all. New Zealand based weed killing trials have proven that nobody does it better.

The trials were conducted by Eurofins Agroscience Services, Hastings, NZ. Ivy and Wandering Trad were treated with Yates Zero Tough weedkiller and two key NZ competitor tough weedkillers in a greenhouse (average air temperature of 13oC), over a 31 day period commencing 25 July 2017.

Check out the graphs and photos below to see how Zero Tough out-performed our competitors. We’re rather proud of the results – and we’re confident it’ll help you deal with the tough weeds at your place.

How To Use

  • Shake well before using.
  • Use Yates Zero Tough on weeds and grasses when they are actively growing with enough healthy leaves to take up the spray.

  • Do NOT spray if rain is likely within 2 hours.
  • Best applied when temperatures are over 10°C.
  • Repeat spray after 2 weeks if necessary.
  • Do NOT apply on or around food or animal feed crops.
  • Do NOT allow spray to contact or drift onto plants you do not want killed – hose off immediately if accidentally sprayed.
