1. A method of plant control comprising:
- treating a plant with a composition comprising a non-transcribable polynucleotide and a transfer agent, wherein said non-transcribable polynucleotide is from 18 to about 700 nucleotides in length and is at least 85% identical or at least 85% complementary to an ACCase gene sequence, or to an RNA transcript of said ACCase gene sequence, wherein said ACCase gene sequence is selected from the group consisting of SEQ ID NOs;
1-92 and a polynucleotide fragment thereof, wherein said transfer agent conditions the surface of said plant for permeation by said non-transcribable polynucleotide, and whereby said plant'"'"'s growth, development, or reproductive ability is reduced or said plant is more sensitive to an ACCase inhibitor herbicide relative to a plant not treated with said composition.
