摘要:
Provided is a stable high-strength herbicidal oil-in-water emulsion composition comprising: a) a discontinuous oil phase comprising, with respect to the oil-in-water emulsion, from about 25 grams active ingredient per liter (g ai/L) to about 300 g ai/L of at least one oil soluble herbicide active ingredient and from 0 grams per liter (g/L) to about 300 g/L of a water immiscible organic solvent b) a continuous aqueous phase comprising, with respect to the oil-in-water emulsion, from about 260 g ai/L to about 570 g ai /L of a water soluble salt of glyphosate and from about 200 g/L to about 500 g/L of water and c) at least two non-ionic ethylene oxide/propylene oxide (EO/PO) block copolymer emulsifying surfactants with at least one having a hydrophile lipophile balance (HLB) value of about 13 to about 16 and at least one having an HLB value of about 22 to about 29 and with each having a molecular weight (mw) of about 5000 or higher, with the combined emulsifying surfactants comprising, with respect to the oil-in-water emulsion, from about 1 g/L to about 200 g/L. A preferred oil soluble herbicide is fluroxypyr-meptyl. Further provided is a method of preparing the composition.
