If you're using it as a weed killer, mix at about 2.5% ratio... in one U.S. gallon, mix about 3 fluid ounces. Be careful of this stuff in dry form, since it's an oxidiser and has been known to cause explosions when clothing is saturated with the powder... Additionally, it's quite persistent. Residual amounts in the soil can be expected for several months to a few years depending on application rates.
If you're killing broadleaf weeds, you might want to consider a selective brand so as to not kill all green leafed plants, such as grass... unless that's your need...
