Grazon Pro is a selective weedkiller for the control of perennial broad-leaved weeds such as nettle, docks & thistle in established grassland. The best method for the effective control of weeds such as these is by using a selective herbicide such as Grazon. Grazon Pro is a strong weedkiller that will control the weeds listed on the label but will not harm grass, making it the market leading product for spot spraying unsightly paddock weeds.
Grazon should be applied from April - October in good growing conditions to a dry leaf. We recommend avoiding spraying if rain is forecast as this may hamper the products effectiveness. To ensure no areas are missed or over dosed, we recommend mixing in Blue Dye which will temporarily colour the area you have sprayed blue. This will in turn save both time and money.
Horses & other livestock will need to be kept out of the treated area until any poisonous weeds such as ragwort have died and become unpalatable. It is important to control weeds such as ragwort as it is toxic to grazing horses and is undesirable in grass grown for silage, hay and haylage. Ragwort is also troublesome as it spreads rapidly; the seeds are easilly picked up by the wind and deposited elsewhere.
Livestock can be returned to the area that has been treated by Grazon Pro weedkiller 7 days after application. Please see the product label for more details and always read before use. If you are unsure please contact our technical team for free, no obligation advice.
