Definitions

  • the present invention relates to a herbicidal combination comprising isoproturon, diflufenican and flufenacet.
  • the present invention also relates to methods of using this combination and the use of the combination to control weeds, particularly Alopecurus myosuroides, commonly known as black-grass. BACKGROUND TO THE INVENTION
  • Alopecurus myosuroides also known as black-grass, slender meadow foxtail, twitch grass and black twitch.
  • Alopecurus myosuroides is an annual grass, often found on cultivated and waste land, and can grow up to 80 cm high, often growing in tufts.
  • Alopecurus myosuroides may be, for example, a weed of cereal crops as it produces a large amount of seed which is shed before the crop is cut. It can occur at very high densities competing with the crop and seriously reducing the yield of crops such as wheat and barley if not controlled.
  • herbicides may be used to control the growth of weeds.
  • EP 021 1518 relates to herbicidal compositions comprising diflufenican in combination with a urea herbicide. Such a combination is said to have a greater than expected activity against certain weed species when applied pre- or post-emergence.
  • EP 0531 1 16 relates to compositions comprising flurtamone and diflufenican and their use in controlling the growth of weeds, for example Avena fatua, Alopecurus myosuroides, Galium aparine and Lolium multiflorum.
  • weeds for example, Alopecurus myosuroides, develop resistance to a range of herbicides used to control them.
  • the present invention provides a herbicidal combination comprising isoproturon, diflufenican and flufenacet.
  • Isoproturon (3-(4-isopropylphenyl)-1 ,1 -dimethylurea or 3-p-cumenyl- 1 ,1 -dimethylurea) is a well-known selective, systemic herbicide used in the control of annual grasses and broadleaved weeds in cereals.
  • Diflufenican N-(2,4-difluorophenyl)-2-[3- (trifluoromethyl)phenoxy]-3-pyridinecarboxamide
  • Flufenacet N-(4-Fluorophenyl)-N-isopropyl-2- ⁇ [5-(trifluoromethyl)-1 ,3,4-thiadiazol-2-yl]oxy ⁇ acetamide
