Herbicidal formulations for triethanolamine salts of glyphosate

Abstract

A high strength herbicidal composition including water; glyphosate, predominantly in the form of a combination of triethanolamine salt and potassium salt in solution in the water in an amount of about 350 grams or greater of acid equivalent per liter of the composition wherein the composition is formulated to include triethanolamine in an amount to form a salt with about 10% or greater, by weight, of total glyphosate and to include potassium in an amount to form a salt with a percentage of total glyphosate so that the combined sum of glyphosate in triethanolamine and potassium salts is more than 50% of total glyphosate; and optionally, one or more surfactants and/or one or more humectants.
