Abstract

The present invention concerns a new use of glyphosate or derivatives thereof for the increase of yield and/or quality of crop plants that are tolerant to glyphosate selected from sugar beet, fodder beet, corn, oilseed rape, and cotton.

Claims

1. A method of increasing the yield of glyphosate tolerant crops selected from the group consisting of:

sugar beet, fodder beet, corn, oilseed rape and cotton;

the method comprising;

treating said crop with an effective amount of glyphosate or a derivative thereof.

2. The method of claim 1, wherein the glyphosate or derivative thereof is applied at a usually lethal dose between 0.18 and 5.3 lb. acid equivalents/acre (0.2 and 6.0 kg acid equivalents/ha).

3. The method of either claim 1 or 2 wherein the glyphosphate or derivative thereof is applied in a single treatment or in successive treatments.

4. The method of claim 3 wherein the glyphosate derivative is a glyphosate salt or a mixture of glyphosate salts selected from the group consisting of:

mono-isopropylammonium glyphosate, ammonium glyphosate, and sodium glyphosate.

5. The method of claim 3 wherein the glyphosphate or derivative thereof is used in a formulation comprising:

an adjuvant selected from the group consisting of;

amines, ethoxylated alkyl amines, tallow amines, cocoamines, amine oxides, quaternary ammonium salts, ethoxylated quaternary ammonium salts, propoxylated quaternary ammonium salts, alkylpolyglycoside, alkylglycoside, glucose-esters, sucrose- esters, and ethoxylated polypropoxylated quaternary ammonium surfactants.

6. The method of claim 3 wherein glyphosate or a derivative thereof is used to increase the yield and/or quality of a sugar or fodder beet.

7. The method of claim 3 wherein the crop contains a gene which encodes EPSPS polypeptide.

8. The method of claim 3 wherein the crop contains a gene encoding a glyphosate oxidoreductase enzyme.

9. The method of claim 3 wherein the crop contains a gene encoding a class II EPSPS enzyme.
