Product Overview

Hammer® 400 EC Herbicide has shown to be a highly effective and versatile tool for broadacre use prior to the establishment of winter and summer crops or commencing and maintaining a fallow. When used in combination with knockdown herbicides, Hammer® 400EC Herbicide significantly increases brownout and improves control of hard to kill weeds such as Marshmallow, Capeweed, Paterson's curse and Wild radish.


Hammer® 400 EC Herbicide is a non-residual, contact herbicide that is readily absorbed by green leaves and stems of broadleaf plants, with no translocation within the plant to roots or to other, unsprayed leaves. When used at the label rates, Hammer® 400EC Herbicide has no residual activity from herbicide that falls onto soil which results in a nil re-cropping interval to all winter and summer crops.


Hammer® 400EC Herbicide shows robust and consistent control of hard-to-kill broadleaf weeds. Hammer® 400EC Herbicide has excellent compatibility with glyphosate and paraquat based herbicides for broad spectrum weed control.
