Methods and compositions for weed control
First Claim
1. A method of controlling a Sorghum species plant comprising:
- treating a Sorghum species plant or a part thereof in need of control with a first herbicidal composition comprising a double-stranded RNA (dsRNA) polynucleotide, an organosilicone surfactant in a concentration of about 0.2 percent or greater by weight, and an effective dose of a nonpolynucleotide herbicide, wherein said dsRNA polynucleotide is identical or complementary to at least 21 contiguous nucleotides of a Sorghum species gene polynucleotide selected from the group consisting of SEQ ID NOs;
26, 27, 30-36, 38-41, 43, 46-57, 59-66, 76, 79, 82, 84, 86, 87, 90, 93-120, 122-129, 131-133, 136, and 140-153, wherein said Sorghum species plant is more sensitive to said nonpolynucleotide herbicide, relative to a similar plant treated with a second herbicidal composition not containing said dsRNA polynucleotide.

Abstract
The present invention provides novel compositions for use to enhance weed control. Specifically, the present invention provides for methods and compositions that modulate gene expression in johnsongrass. The present invention also provides for combinations of compositions and methods that enhance johnsongrass control. The invention comprises a method of Sorghum species weed control, in particular johnsongrass (Sorghum halepense) plant control comprising an external application of a herbicidal composition to a Sorghum halepense plant or a part of the Sorghum halepense plant in need of control, said herbicidal composition comprising a polynucleotide, an organosilicone surfactant concentration of about 0.2 percent or greater, and an effective dose of a nonpolynucleotide herbicide.
