The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type or a mutated protoporphyrinogen oxidase (PPO) which is resistant or tolerant to a PPO-inhibiting herbicide by applying to said site an effective amount of said herbicide. The invention further refers to plants comprising wild-type or mutated PPO enzymes, and methods of obtaining such plants.

Plants having increased tolerance to herbicides

Transgenic or non-transgenic plants with mutated protoporphyrinogen oxidase having increased tolerance to herbicides

The invention refers to plants comprising wild-type or mutatedPPO enzymes, and methods of obtaining such plants. The present invention further refers to a method for controlling weeds at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type or a mutatedPPO enzyme which is resistant or tolerant to a PPO-inhibiting herbicide by applying to said site an effective amount of said herbicide.

The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type or a mutated protoporphyrinogen oxidase (PPO) which is resistant or tolerant to a benzoxazinone-derivative herbicide by applying to said site an effective amount of said herbicide. The invention further refers to plants comprising wild-type or mutated PPO enzymes, and methods of obtaining such plants.

The present invention refers to a plant or plant part comprising (i) a recombinant polynucleotide encoding a wildtype or mut-PPO polypeptide, and (ii) a recombinant polynucleotide encoding a CYP450 polypeptide, the expression of said polynucleotides (i) and (ii) confers to the plant or plant part tolerance to PPO-inhibiting herbicides.

The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a mutated protoporphyrinogen oxidase (PPO) which is resistant or tolerant to a PPO-inhibiting herbicide by applying to said site an effective amount of said herbicide. The invention further refers to plants comprising mutated PPO enzymes having a substitution at a position corresponding to position Leu397 of SEQ ID NO:2 and an amino acid substitution at a position corresponding to position Phe420 of SEQ ID NO:2, and methods of obtaining such plants.

The present invention relates to a method for enhancing the performance of a pesticide comprising the step of contacting an adjuvant and the pesticide, wherein the pesticide is present in a concentration of less than 10 wt % in the resulting composition containing the adjuvant and the pesticide, and wherein the adjuvant contains a guanidine of formula (A) as defined below, and/or a salt thereof. The invention also relates to a composition comprising an auxin-herbicide and said adjuvant; to a use of said adjuvant for enhancing the performance of a pesticide; and to a method of controlling undesired vegetation, which comprises allowing a herbicidal effective amount of said composition to act on plants, their habitat or on seed of said plants.
