Abstract
The present invention provides novel compositions for use to enhance weed control. Specifically, the present invention provides for methods and compositions that modulate glutamine synthetase in weed species. The present invention also provides for combinations of compositions and methods that enhance weed control.
Claims20
A method for potentiating activity of a glutamine synthetase (GS) inhibitor herbicide in a plant comprising
- (a) applying to a surface of the plant a composition comprising at least one non-transcribable polynucleotide and a transfer agent,
- wherein the at least one non-transcribable polynucleotide is from 21 to about 700 nucleotides in length and is identical or complementary to at least 21 contiguous nucleotides of a glutamine synthetase (GS) gene sequence or an RNA sequence thereof, wherein the GS gene sequence is selected from the group consisting of SEQ ID NOs:
- 1-4, 6-389, and 392-2056, and
- wherein the transfer agent conditions the surface of the plant for permeation by the at least one non-transcribable polynucleotide, and
- (b) applying the GS inhibitor herbicide to the plant;
- whereby the at least one non-transcribable polynucleotide permeates the interior of the plant and induces suppression of a GS gene, thereby potentiating activity of the GS inhibitor herbicide in the plant.

A method of reducing growth, development, or reproductive ability in a plant, comprising
- treating a plant with a GS inhibitor herbicide in combination with
- (a) at least one non-transcribable polynucleotide that is
- from 21 to about 700 nucleotides in length and is identical or complementary to at least 21 contiguous nucleotides of a glutamine synthetase (GS) gene sequence or an RNA sequence thereof, wherein the GS gene sequence is selected from the group consisting of SEQ ID NOs:
- 1-4, 6-389, and 392-2056, and
- (b) an organosilicone surfactant,
- whereby growth, development, or reproductive ability is reduced in the treated plant compared to a control plant treated with the GS inhibitor herbicide alone.
