Abstract

The invention pertains to a method for manufacture and use of pesticides or agricultural spray adjuvants that counteracts the effects of hard water cat ions on anionic pesticides when applied in water spray solutions.

Claims

1. A water soluble glyphosate composition comprising:

(a) an aqueous glyphosate solution comprising glyphosate or a salt thereof;

(b) a concentrated solution comprising sulfuric acid and a polyamine surfactant selected from tallow amine ethoxylate and coco amine ethoxylate combined in an agricultural spray solution;

wherein said composition does not contain ammonium sulfate (AMS); and

wherein said composition consists of a ratio of 1 quart to 2 gallons of (b) to 100 gallons of (a); and

wherein said composition has a pH above the PKa₂ of glyphosate, and wherein better herbicidal efficacy is provided in comparison to 5-20 pounds AMS per 100 gallons of (a).

2. The composition as claimed in claim 1, wherein said acid has the ability to completely or nearly completely dissociate in water and react with cations.

3. The composition as claimed in claim 1, wherein said polyamine surfactant is tallow amine ethoxylate.

4. The composition as claimed in claim 1, wherein said polyamine surfactant is coco amine ethoxylate.

5. A water soluble glyphosate composition of claim 1 wherein said composition consists of a ratio of 1 quart to 1 gallon of (b) to 100 gallons of (a).

6. The composition as claimed in claim 1, further comprising sodium bisulfate.
