Claims
- 1. A herbicidal composition comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of about 40 to about 48 percent N-phosphonomethylglycine acid equivalent by weight.
- 2. The composition of claim 1 further comprising a surfactant component in solution or stable dispersion in water, comprising one or more surfactants in a total amount of about 20 to about 200 grams per liter of the composition;wherein said surfactant component is selected such that the composition has a cloud point not lower than about 50° C.
- 3. The composition of claim 2 wherein said surfactant component is selected such that the composition exhibits no crystallization of said N-phosphonomethylglycine or salt thereof when stored at a temperature not lower than about 0° C. for a period of up to about 7 days.
- 4. The composition of claim 2 wherein the total amount of surfactant is about 60 to about 200 grams per liter of the composition.
- 5. The composition of claim 2 wherein the glyphosate concentration, expressed in percent a.e. by weight, is higher than the maximum concentration that would provide acceptable storage-stability if all of the glyphosate were instead present as the isopropylammonium salt.
- 6. The composition of claim 2, wherein the surfactant concentration, expressed in g/l, is higher than the maximum concentration that would be attainable if all of the glyphosate were instead present as the isopropylammonium salt.
- 7. The composition of claim 2 having a viscosity less than an otherwise similar composition wherein all of the glyphosate is instead present as the isopropylammonium salt.
- 8. A herbicidal composition comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of not lower than about 40 percent N-phosphonomethylglycine acid equivalent by weight.
- 9. A herbicidal method comprising diluting in a suitable volume of water a herbicidally effective amount of a composition of claim 2 to form an application composition, and applying the application composition to foliage of a plant or plants.
- 10. A herbicidal method comprising diluting in a suitable volume of water a herbicidally effective amount of a composition of claim 8 to form an application composition, and applying the application composition to foliage of a plant or plants.
- 11. A herbicidal composition comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of not lower than about 420 grams N-phosphonomethylglycine acid equivalent per liter of the composition.
- 12. A herbicidal method comprising diluting in a suitable volume of water a herbicidally effective amount of a composition of claim 11 to form an application composition, and applying the application composition to foliage of a plant or plants.
- 13. A herbicidal composition comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of not lower than about 480 grams N-phosphonomethylglycine acid equivalent per liter of the composition.
- 14. The composition of claim 13 wherein said N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, is in solution at a concentration of about 480 to about 540 grams of acid equivalent per liter of the composition.
- 15. A herbicidal method comprising diluting in a suitable volume of water a herbicidally effective amount of a composition of claim 13 to form an application composition, and applying the application composition to foliage of a plant or plants.
