Hammer Herbicide 5L

Hammer is a rapid action total herbicide containing a brand new active ingredient combination of Pyraflufen-ethyl and Glyphosate which kills most annual and perennial broad-leaved and grass weeds when used as directed.

Hammer 5L - MAPP no. 15060


Active Ingredients: 240g/l Glyphosate and 0.67g/l Pyraflufen-ethyl as a Suspo-emulsion.
Hammer has approval for use on hard surfaces, in addition to natural surfaces not intending to bear vegetation.

The unique combination of Pyraflufen-ethyl and Glyphosate was developed by scientists in France and the UK, and trialled over the course of two years at the company's Levington Research Station near Ipswich and on areas of non-cultivated and industrial land.

Pyraflufen-ethyl acts rapidly causing the visible signs of destruction of the aerial part of the plant within 24 hours by inhibiting the enzymes that drive photosynthesis, while the systemic action of Glyphosate, completes the total kill.

Hammer effectively controls a broad spectrum of annual and perennial weeds, including the tough brush weeds bramble and bracken.

Applied post-emergence, Hammer is ideal for application between April and September when weeds are actively growing. Once applied, it's rainfast within six hours.
