- Find out what makes Weed Weapon the best weed killer.
- Weed Weapon contains two active ingredients of different types. These actives, glyphosate and saflufenacil, work together in what is called a synergistic way; improving the efficacy of both when used together.
The use of two active ingredients also means that it will control weeds that might be resistant or tolerant of glyphosate alone, and it greatly reduces the risk of development of resistance in weeds.
Resistance to herbicides through overuse of the same single active ingredient is a concern for farmers, horticulturalists and gardeners. It is good practice to use products that combine actives of different types to prevent resistance developing. - Watch our videos on Weed Weapon weed killers.

I tried Weed Weapon on the weekend, spraying all the weeds in our paths then went out for a couple of hours. When I came home, all the leafy weeds had turned completely black and the grassy ones had browned-off considerably. Couldn't believe my eyes!

On Saturday the 26th of October I purchased a 2.5 litre container of ready to use Weed Weapon . The main weed issue I had was thistle and stinging nettle. Within 24 hours my weed problem was completely taken care of. I had tried other weed killer brands without satisfactory results. I wish to thank you for producing a GREAT NZ product at a GREAT price that does an EXCELLENT job.
