Group 4 Herbicide Grazon Extra is primarily used for brushweed control plus difficult to control broadleaf weeds in fallow situations in northern Australia. In Southern Australia i t is the standard for volunteer lucerne removal prior to cereal cropping. Grazon Extra uses place cell growth disruption (all pyridines) to control the weeds. Key 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. Show more
