Winter Grass Killer
Winter Grass Killer is a selective herbicide for control of winter grass that is suitable for use on couch, bent, buffalo, ryegrass, brown top and Kentucky Blue Grass. It is not suitable for use on Kikuyu or fescue lawns.
The product breaks down quickly – no residue in soil and is economical to use as 15 mL treats 100 square metres of lawn. Winter Grass Killer should be applied as a fine spray as soon as the winter grass appears and before it has a chance to flower and set seed.
Winter Grass (Poa Anna)
This weed is difficult to control as it has built up resistance to most chemicals. It is also very active in winter, when most lawn varieties have gone dormant. New varieties of turf that resist winter dormancy, such as Sir Walter Soft Leaf Buffalo, Tif Tuf and Sir Grange, are much better at resisting the invasion of winter grass. In those older varieties of grass, such as winter green couch, Qld Blue etc that go dormant in winter, it is often only the winter grass that gives your lawn any colour. Ideally, you should not allow winter grass to take over those dormant lawns. The winter grass will compete and win for any available nutrients spreading thicker each year
When to Use
You apply this product after the winter grass has come up, however the longer you leave it the less effective the chemical will be. Completely eradicating the weed before it seeds and improving the general health and coverage of your lawn will help you to control weeds in your lawn. All weeds are easier to kill when they are healthy with more surface area to suck up the chemical, so try not to mow the lawn before spraying. Try and spray when the weed is more juvenile. This way you spray before it seeds and before the stem gets more mature and woody. This will allow the chemical to be absorbed better into the plant.
How to use
Dilute 15ml of Winter Grass Killer in 10 litres of water and apply over 100 square metres of lawn.
