Abstract
The present disclosure relates to the use of certain substituted phenyl uracils comprising a cyclopropylcarboxylic acid-based side chain, or agrochemically acceptable salts thereof, for controlling or preventing weed growth in plant growth areas of transgenic crop plants that are tolerant to PPO inhibiting herbicides. The disclosure also provides herbicide tolerant transgenic plants, seeds, cells, and plant parts containing the recombinant DNA molecules, as well as methods of using the same.
Claims22
A method for controlling or preventing weed growth in a plant growth area, wherein the method comprises the steps of:
- (a) providing in said plant growth area a plant or a seed that when grown produces said plant, wherein the plant comprises a recombinant DNA molecule comprising a DNA sequence encoding a heterologous HemG protein, wherein said protein confers tolerance in said plant to an herbicidally active compound corresponding to a compound selected from the group consisting of A1, A2, A3, A4, A5, A6 and A7, or an agrochemically acceptable salt thereof, wherein:
- A1 corresponds to:
- 1-ethoxy-1-oxopropan-2-yl 1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate;
- A2 corresponds to:
- 2-{[(1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl] phenoxy}cyclopropyl) carbonyl] oxy}propanoic acid;
- A3 corresponds to:
- 1-methoxy-1-oxopropan-2-yl 1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate;
- A4 corresponds to:
- 1-ethoxy-2-methyl-1-oxopropan-2-yl 1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate;
- A5 corresponds to:
- 1-ethoxy-1-oxobutan-2-yl 1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate;
- A6 corresponds to:
- 1-(ethoxycarbonyl)cyclopropyl 1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate;
- A7 corresponds to
- 1-(allyloxy)-1-oxopropan-2-yl1-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1 (2H)-yl]phenoxy}cyclopropanecarboxylate And
- (b) applying to said area an amount of said compound effective to control or prevent weed growth in the area.
