Fertilome (11262) DECIMATE Weed & Grass Killer (32 oz)

NO Glyphosate! And it works much better on the grasses and weeds in my decorative rock in Arizona at 5000 ft elevation. Ferti-lome Decimate uses Glufosinate-ammonium as its active ingredient which is less harmful to the environment. I started using this product when a local nursery recommended it for a weed that loves winter temperartures. The directions say it works best at 80 degrees F or higher but it works for me at daytime temperature between 40 and 60, it just takes longer, The price through Walmart is much lower than what I paid at the nursery and the delivery was quick.
