Woody Weeds

Grazon® Extra

Herbicide

Grazon Extra is primarily used for brushweed control plus difficult to control broadleaf weeds in fallow situations in northern Australia. In Southern Australia it is the standard for volunteer lucerne removal prior to cereal cropping.


Features

Mode of action

Acts on both foliage and roots to provide rapid brownout of leaves, dry down of stems and destruction of the root mass to prevent regrowth.

Residual activity

Ingredients remain active in the soil and prevent seeds of the target woody plants and secondary weeds from germinating for many months after application (in some cases up to two years).

Selectivity

Controls the target weeds without harming pasture grasses.
