- Weed Weapon Long Term contains two post-emergent 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.
Weed Weapon Long Term contians a third active which is a pre-emergent and prevents new weeds emerging for an extended period. - Watch our videos on Weed Weapon weed killers.

By the way, this stuff is awesome, got rid of the little weeds trying to come through my nice new driveway in days!

Hi guys, just a quick note to let you know how pleased I am with your weed weapon [Long Term] formula. I applied this mid winter and was skeptical that it was going to work. Then suddenly the weeds died very soon after. I realise that applying in summer would work quicker. I was impressed that it killed the moss in our pavers as well and after 2 or 3 months has not reappeared.
