Abstract:
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.
Abstract:
The present invention relates to a method for improving the efficacy of anionic herbicides (B) under hard water conditions, comprising the steps of a) providing at least one anionic herbicide (B) and at least one aminocarboxylate (A), selected from the group consisting of methylglycine diacetate (MGDA; A1), glutamic acid diacetate (GLDA; A2), iminodisuccinate (IDS; A3), N-(2-hydroxyethyl)imino diacetate (HEIDA; A4), ethylenediamine-N,N′-disuccinate (EDDS; A5) and their salts; b) diluting components (A) and (B) with water, wherein the concentration of dissolved calcium, magnesium, iron and aluminum salts in said water is more than 120 ppm; and c) applying the diluted mixture to the area to be treated.
