Woody Weeds Infestations

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).
