Claim:
1. An herbicidal composition for weed control in crops genetically engineered for tolerance to glyphosate or other herbicides, comprising glyphosate salt and phosphite at a molar ratio of about 1:2 to about 4:1 glyphosate salt to phosphite; wherein the composition is formulated by combining the glyphosate salt with a phosphite, or with a polyphosphite, or with a combination of phosphite and polyphosphite; wherein the composition is formulated as a liquid for dilution to an application rate of the dissolved glyphosate salt of between about 0.47 pounds per acre and about 4.13 pounds per acre; and wherein the composition is effective in controlling weed growth in the genetically engineered crop while reducing setback or yield drag in the crop to which it is applied, as compared with an equivalent crop treated with an equivalent amount of the glyphosate salt in the absence of the phosphite.
