Abstract:
1. A method for selectively controlling targeted herbicide-resistant weeds or volunteer plants comprising topically applying onto a surface of said weeds or volunteer plants one or more polynucleotides and a transfer agent in a manner that does not integrate said one or more polynucleotides into a chromosome of said weeds or volunteer plants; wherein said transfer agent is selected from the group consisting of an organosilicone surfactant and a cationic lipid; wherein said transfer agent enables said one or more polynucleotides to permeate from the surface of said weeds or volunteer plants into cells of said weeds or volunteer plants; wherein said one or more polynucleotides comprise a sequence essentially identical or essentially complementary to a coding or non-coding sequence of an endogenous gene of said weed or volunteer plant or a messenger RNA that is transcribed from an endogenous gene of said weed or volunteer plant; and wherein said endogenous gene: (i) is an essential gene for maintaining the growth or life of said weed or volunteer plant, (ii) encodes a protein that provides herbicide resistance to said weed or volunteer plant, or (iii) transcribes to an RNA regulatory agent.
