Claims
- 1. A method of herbicidally controlling weeds selected from the groups consisting of annual grasses, annual broadleaves, perennial grasses and perennial broadleaves by contacting said weeds with a herbicidally effective amount of a composition sufficient to provide from about 0.1 to about 0.5 pound per acre of the isopropylamine salt of glyphosate and an effective potentiating amount of from about 2 to about 4 pounds per acre of ammonium thiocyanate, wherein the weight ratio of ammonium thiocyanate to the isopropylamine salt of glyphosate in the composition is within the range of from about 4:1 to about 40:1, sufficient to enhance the herbicidal activity of the glyphosate.
- 2. A method according to claim 1 wherein the weeds are selected from the group consisting of ryegrass, mixed crabgrass, mixed foxtails, mixed bluegrass, mixed fescues, Canada thistle, chickweed, common dandelion, yellow nutsedge, common lambsquarter and johnsongrass.
