1. A method of Lolium species plant control comprising:
- treating a Lolium 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 Lolium species gene polynucleotide selected from the group consisting of SEQ ID NOs;
46, 65, 88, 89, 91, 92, 94, 95, 98, 99, 104, 105, 114, 122-126, 129-134, 136, 138, 139, and 145-151, wherein said Lolium 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.
