Grosafe Prickle Weedkiller controls Onehunga weed and other broadleaf lawn weeds.
Grosafe® Prickle Weedkiller is a selective weedkiller for the control of Onehunga weed and other broadleaf lawn weeds. Contents will treat 100 square metres of lawn. Onehunga weed is very common in New Zealand lawns, producing a mass of small prickles over the summer. The optimum time to apply Grosafe® Prickle Weedkiller is in October, after the majority of plants have germinated and before they set seed. A second spray in autumn will reduce the problem for next season. Do not apply below 18oC or variable results may be achieved. Other lawn weeds controlled by Grosafe® Prickle Weedkiller include thistles, plantains, daisies, Cape daisy and pennycress.
Directions: Shake well. Mix 10ml per litre of water and apply to 5 square metres using a spray unit or water can. Best applied to short evenly mown lawn under active growing conditions to ensure an even coverage of all foliage. Do not spray if rain is likely within 24 hours. Keep pets off treated lawns until the spray is dry.
Caution: Applying a higher rate than 1 litre per 5 square metre may result in burning
